Mr. Krabs loves money, and is openly concerned about his profits above all else. Because of this, he pays his employees very cheaply (though SpongeBob doesn't care much) and serves his food for high prices.
The reason the restaurant is so popular is because of the Krabby Patty, a burger with a very top secret recipe, which has almost always been the signature Krusty Krab dish. Other Krusty Krab grub includes typical fast food products such as french fries and sodas, as well as underwater foods such as coral bits and kelp rings. All of these items make up the Galley Grub, the food menu of the Krusty Krab.
Besides Mr. Krabs, the restaurant has two employees: SpongeBob as the fry cook and Squidward as the cashier.
SpongeBob loves his job and excels at it, while Squidward loathes his job and does his job poorly. Squidward is annoyed by SpongeBob, though SpongeBob considers him to be one of his best friends.
The Krusty Krab's main business competitor is the Chum Bucket, owned by Plankton, who is Mr. Krabs' worst enemy (and former best friend).
While the Chum Bucket (the restaurant's only competitor) usually fails to attract customers due to its repulsive food products, there have been short instances where the Chum Bucket was doing successfully. These infrequent short periods of time are the only times when the Krusty Krab has any competition.
Stephen Hillenburg's original name for the Krusty Krab was the "Crusty Crab," but he decided the intentional misspellings of the "C"s for "K"s was funnier.
The restaurant itself may have once been an old New England lobster trap since it greatly resembles one. The original owners may have found the trap lying at the bottom of the ocean, and fixed it up and turned it into a building. Another theory is that the restaurant could have been purposely designed to resemble a lobster trap so it could look more nautical than a regular building.
In one version of the origin, the Krusty Krab was born when Mr. Krabs, who had been secluded in a deep depression after serving in the military that seemed endless, acquired a bankrupt retirement home called the "Rusty Krab."
However, in another version of the origin, Mr. Krabs was once a seafaring pirate and the Krusty Krab was originally his ship.
However, it is said that after retiring from piracy, Mr. Krabs sold his ship. He could have purchased the retirement home after this, and it could have been a coincidence that it was called the Rusty Krab and had the same shell design as Mr. Krabs' ship.
In "Friend or Foe," which revealed the origin of Mr. Krabs and Plankton's rivalry, it is shown that Mr. Krabs first went into the fast food business in his childhood. The Krabby Patty secret formula was created when a shelf was broken during Krabs and Plankton's struggles, making various ingredients slide into the patty batter. However, other episodes, most notably "Enemy In-Law," state that the Krabby Patty and its formula is a family recipe, such as in "Dunces and Dragons," which shows that the Krabby Patty was first served in medieval times by King Krabs, an ancestor of Mr. Krabs, who was introduced to it as a result of SpongeBob and Patrick's time traveling. As for salaries, Squidward and SpongeBob, the only two employees besides their boss Mr. Krabs, have varying salaries depending on the episode that are mostly for the joke. In some instances, they are paid an actual (if not minimal) paycheck, while some other instances show that they actually are to pay Mr. Krabs (this is most notable in the episode "Squid on Strike," where Squidward is forced to pay for his services). Another episode shows they are paid only one nickel (5 cents) a day, according to an episode in which Squidward mentions this fact and SpongeBob cannot stop laughing. "One Coarse Meal" shows that Mr. Krabs pays SpongeBob with Wacky bucks, a fake currency which obviously has no value, only just for a gag. In yet another episode, SpongeBob states that he had to pay Mr. Krabs $100 an hour when he first started working.
Design and features
The Krusty Krab building has a wooden chassis with glass windows/walls and appears from the outside as an old lobster trap. There is a large clam-shaped sign in front of the restaurant, similar to those used by real-life fast food restaurants, and five international maritime signal flags above the front door. There is a pole outside its right window as seen in the episode "My Pretty Seahorse." It shares a resemblance to a New England lobster trap. It might have just been built to look like a lobster trap, but it is also possible that it was actually formed from an old sunken lobster trap.
There is no parking lot, although boats always park outside on a road surrounding the restaurant. It is unknown how so many customers can fit inside the Krusty Krab, when there are no cars, but most customers walk to the restaurant, as seen in many episodes including it.
The drive-thru is seen throughout the first four seasons and in season twelve, but its most notable appearance is in the episode "Driven to Tears" when Mr. Krabs introduces it to SpongeBob. It is removed until the episode "Drive Thru," when an un-repaired hole is mistaken for a drive-thru, causing chaos at the Krusty Krab. Its purpose was to serve travelers and tourists that did not have time to eat at the Krusty Krab. In "Driven to Tears," it resembles a modern drive-thru, but in its latest appearance, it is cheaply built. It used tin cans with string for microphones, old napkins for a menu board, and a bent noodle for a sign. The drive-thru was gotten rid of after it caused chaos in the Krusty Krab. There is another drive-thru on the backside of the restaurant which appears in The SpongeBob Movie: Sponge Out of Water when Sandy is ordering Krabby Patties it also appears in "Bubble Bass's Tab" where Bubble Bass tries not to pay his tab and in "Drive Happy."
Other exterior features
In the episode "The Clash of Triton," Mr. Krabs is seen placing a wooden sign saying "No Refunds" to the ticket-buying crowd watching the boring drama within the Krusty Krab.
Like other buildings in the series, the Krusty Krab's interior design is sometimes highly inconsistent between episodes. The Krusty Krab's basic floor plan consists of one main eating area, with the kitchen, Mr. Krabs' office, and bathrooms in separate rooms at the back of the restaurant. There is also a crow's nest located in one of the pillars.
The order stand consists of a small boat directly in front of the window leading to the kitchen.
To go with the show's nautical theme, the Krusty Krab bears a striking resemblance to a New England lobster trap. When someone first enters inside, there is the main eating area, which, like most fast-food joints, is the largest room in the restaurant. The tables are made out of sailing ship steering wheels, with barrels as chairs. Near the kitchen door is the order station, where the cash register is located and where Squidward works, taking customers' orders and giving them to SpongeBob through the order window which is shaped like the bow of a ship. In some episodes, there is a salad stand near the order window, and a "Condiment Island" stand, with ketchup and the like. At the back of the restaurant are many rooms, which are very inconsistent but mostly correct in the following order. In "Krabs à la Mode," a thermostat is shown inside of the Krusty Krab. Mr. Krabs installs a ceiling fan in "SpongeBob vs. The Big One." It also has a small area in between the roof of the kitchen, Mr. Krabs' office, and the bathrooms, which appears to be a storage area. It is featured in "Penny Foolish," when Squidward sits on a box holding a flashlight over Krabs, and in "Truth or Square," when the crew broke a ventilation vent in order to get off of the air ducts. The Krusty Krab also features a "lock down" mode, in which metal plates guard the doors and windows.
On the far left is Mr. Krabs' office where Mr. Krabs works as an employer, with a money safe, a desk made out of an old sea trunk, chairs made out of old barrels, pictures, money on the wall, etc. There is also a door to the kitchen, where Krabs can check on SpongeBob from the kitchen. The safe is also where the Krabby Patty secret formula is located most of the time, and Mr. Krabs' money is hidden. On the other side of the wall, there are flags, a window, and a shelf where it holds artifacts.
There is a running gag where Krabs is seen admiring money in some way. This includes Mr. Krabs taking a money bath in the episode Nasty Patty. Sometimes he gets caught in the act by SpongeBob.
In the episode "Mermaid Pants," it is revealed that Mr. Krabs has a secret room behind the shelf where he stores many comic books. Mr. Krabs pulls on one of the books, revealing another secret room where his Captain Tightwad outfit is stored behind the back wall of the secret room.
Regarding its role in the series, many appearances of Mr. Krabs' office occur whenever employees need or want to see Mr. Krabs. In the episode "The Algae's Always Greener," however, it is the place where Mr. Plankton, Plankton's Mr. Krabs life-switched counterpart, resides.
The kitchen is SpongeBob's station where he makes the Krabby Patties and stores his cleaning supplies. It has a grill for cooking patties. There are storage cupboards for ingredients. A window is seen, which is used to place orders and to serve them once they are done. The kitchen is commonly used as a storage space.
The grill sits in the middle of an internal wall of the Krusty Krab, with a kitchen window placed above the grill, in which SpongeBob can easily give the Krabby Patties to Squidward. To the right of the grill is a fryer. On the back wall is a cupboard and some wooden barrels. One of the walls consistently has a bottle of ketchup, mustard, and mayonnaise on a kitchen shelf, as well as many black-colored pots and pans hanging on the wall.
In some episodes, it is vast, holding a "Patty Vault" full of Krabby Patties, a freezer that Squidward was frozen in for 2,000 years once, and many other hallways and rooms. Also, as seen in "Planet of the Jellyfish," the freezer now holds cases of mayonnaise. It has a refrigerator before in "Pat No Pay." According to the episode "Restraining SpongeBob," the kitchen's width is about 15 ft.
In the episode "Lost and Found," a trapdoor is located in the kitchen, leading to the Krusty Krab's "Lost and Found" room, where all items and people lost in the restaurant are stored until they're reclaimed.
There is one restroom located on the far back right of the dining room. It has urinals, toilets, and sinks. A sign saying to wash fins can be seen written in both English and Spanish. In most episodes, there are two or sometimes three stalls.
Other interior features
Most notably in "Truth or Square," there are shown to be many nooks and crannies in the Krusty Krab, such as a massive ventilation system. That system also has a surveillance room where there are computers that spy on every house in Bikini Bottom. In various episodes, it is shown to be hosts to several secret passages and rooms. Some examples are found in "Truth or Square" and "Chum Bucket Supreme."
There is also a storage room where food and other items are commonly stored.
In the episode "Born Again Krabs", a device known as the Pinch-o-Matic is shown to be installed in the kitchen. Its purpose is to state how much money is saved whenever an object is removed from the trash.
In the episode "Breakin'," an "Employee Break Room" is shown. The door of the room is located between the ones for the kitchen and the restroom, and it is hidden underneath the metal plating of the wall, a layer of wallpaper, and a layer of brick wall. The room's interior features a table and a chair, an old microwave and an old fridge, some shelves with miscellaneous items in them, a few posters, and a lightbulb hanging from the ceiling.
At the end of the episode "Squidtastic Voyage" shows Mr. Krabs wiping a "No Refunds" sign inscribed onto a golden slab near Squidward's workstation.
Apart from its excellent food, the Krusty Krab exhibits many of the undesirable qualities of real-life fast food restaurants. It is dirty and cheaply maintained, and the restaurant is sometimes shown to be in a state of disrepair. This is shown by the "faulty wiring" and green slime oozing from the walls in "Graveyard Shift."
In the "Krusty Krab Training Video," basic features of modern fast food restaurants implemented by the Krusty Krab are described as "the latest achievements in fast food technology" and given extravagant descriptions. This "technology" includes:
Policies and disclaimers held by The Krusty Krab for the employees include:
The Krusty Krab Employee Manual; Second revised edition; page 35; section 19; Clause 3A: All staff must remain on the premises until the day's receipts are fully accounted for. This is seen in "Can You Spare a Dime?."
The Krusty Krab Employee Manual; Second revised edition; page 35; section 19; Clause 3B: The proprietor reserves the right to be unfair. This is also seen in "Can You Spare a Dime?."
Think of the customer.
We serve all kinds. This is seen in "Bubble Buddy."
Everyone's money is good (an escaped convict with a sack of stolen money is shown eating a Krabby Patty). This is also seen in "Bubble Buddy."
The customers' jokes are always funny. This is seen in the episode "Sponge-Cano."
Krusty Krab Rule book; Rule #2: Never disclose the location of the secret formula! This is seen in "One Coarse Meal."
The Industries Labor Agreement; Section 9 number 34.44/429b specifically prohibits the disclosure of the secret formula to friends, even when those friends are "closer 'n two catfish in a skillet". This is seen in "Someone's in the Kitchen with Sandy."
Employees are granted a discount on food they ordered. This is seen in the episode "To Love a Patty."
Employees can have worker's compensation: Employees get paid while they are at home. This is seen in "The Splinter."
Policies and disclaimers held by The Krusty Krab for the customers include:
The Krusty Krab policy clearly states that once the patty has reached the customer, it is his / her responsibility. This is seen in "Born Again Krabs."
Money back guarantee (seen only in microscopic print). This is seen in "Pickles."
Policies and disclaimers held by The Krusty Krab for both customers and employees include:
The Krabby Patty secret formula is the sole property of The Krusty Krab and is only to be discussed in part or in whole with its creator Mr. Krabs. Duplication of this formula is punishable by law. Restrictions apply, results may vary. This is seen in "Imitation Krabs."
No outside beverages. No exceptions. This is stated in "Best Frenemies."
Nobody eats in The Krusty Krab for free (royalty or not). This is seen in "Rule of Dumb."
Due to Mr. Krabs' cheapness, The Krusty Krab is rarely shown to have any significant advertising, but has on several significant occasions. One of his methods of advertisement seen in the episode "As Seen on TV" was commercials.
Squidward is the director at first, but when Krabs sees the insane values of Squidward's commercial, he fires the crew and directs an extremely cheap and poorly made commercial using only himself, his employees, and his daughter. The commercial was shown in the "prime time slot" of 3:28 AM, and featured Pearl and Squidward playing teenage girls getting their first Krabby Patty from Mr. Krabs. SpongeBob made only two partial cameos in the commercial, but was extremely excited to see himself on TV and believed that he was now a celebrity. In the commercial, The Krusty Krab's slogan is jokingly shown to be "Come spend your money here!"
In order to attract new regulars into his restaurant, Krabs advertised his restaurant in a local newspaper in extremely small print (so small that anyone would need a magnifying glass to see), as seen in "The Krabby Kronicle."
In "Mermaid Man vs. SpongeBob," Mermaid Man and Barnacle Boy are hired to promote the restaurant, appearing in TV commercials for it. Kids meals are produced featuring Mermaid Man and Barnacle Boy toys. In "Bummer Vacation," SpongeBob is shown to own a Krusty Krab play set, which includes figures of SpongeBob, Mr. Krabs and Squidward. In "Yours, Mine and Mine," it is seen to have a toy made out of the Krabby Patty, which SpongeBob calls a Patty Pal. In "Born Again Krabs," Krabs sells Bikini Bottomite action figures until he realizes he is awake.
Mr. Krabs' Greedy Plans
Krabs has done more than 25 scams to try and get as much money as possible. His most villainous scam so far is the newspaper scam in “The Krabby Kronicle.”
Other than Mr. Krabs himself, The Krusty Krab has only two full-time employees: The fry cook, SpongeBob, and the cashier Squidward.
Squidward is the cashier, and stands in a boat taking orders for the entire work day. Squidward has also served as a fry cook in various episodes, including "Bubble Buddy," "Pickles," and "Breath of Fresh Squidward." Squidward hates his job, The Krusty Krab, Krabby Patties (unless the viewer is watching "Just One Bite"), and his peers at work. Despite his dissatisfaction, he makes little effort to find a different job, and has attempted to quit on only a few occasions, most notably in "Can You Spare a Dime?" The possible reason for his hatred to his job is having to work with SpongeBob (who in some episodes such as "Restraining SpongeBob" and "Squid on Strike") has gotten Squidward injured or in trouble with Mr. Krabs. The other possibility is the fact that despite his work it has been shown that even SpongeBob (the better worker) gets paid very little and knows that Krabs would be too cheap to raise his pay despite his work effort.
SpongeBob is the fry cook of the restaurant. In "The Original Fry Cook," Jim, quits after Mr. Krabs refused to give him a raise. He first applied for the job in "Help Wanted," the pilot episode of the series. Mr. Krabs and Squidward, wanting no part of him, sent SpongeBob on a fool's errand. While he was gone, an enormous crowd of anchovies stormed the restaurant, nearly killing Squidward and Krabs. When SpongeBob returned, he demonstrated his superhuman fry cook skills, serving all the anchovies, saving Squidward and Krabs, and securing his job. SpongeBob has been assigned other duties in various episodes, including has janitorial duties, "co-cashier" in "The Algae's Always Greener," "Parking Lot Litter Patrol" in "SpongeBob Meets the Strangler," "well money-retriever" in "Wishing You Well," and Lead Reporter for the Krabby Kronicle in "The Krabby Kronicle." At the end of The SpongeBob SquarePants Movie, SpongeBob is hired as the manager of the new Krusty Krab 2. According to the episode "Stanley S. SquarePants," SpongeBob's exact job title is "Vice Assistant General Manager in charge of certain things." It has been shown that he takes his job very seriously. As shown in "Pizza Delivery" he nearly gets both himself and Squidward to starve and get sucked into a tornado when refusing to relinquish the pizza showing that he would rather get both himself and Squidward killed then go with even one unsatisfied customer. He also seems to care less up to the point of obliviousness about Mr. Krabs' utter cheapness despite the fact that he pays them very little and has numerous times put his employees into physical harm in hopes of making even a small amount of money.
In various episodes, the Krusty Krab has hired additional employees. None maintain their job for more than one consecutive episode.
Patrick has worked at the Krusty Krab in several episodes. He was first hired at The Krusty Krab in the episode "Arrgh!," only to be immediately fired (and again later for the second time). He first properly worked at The Krusty Krab in "Big Pink Loser." In "Squilliam Returns," Patrick is assigned the role of hat-taker when Squidward takes over the restaurant to impress Squilliam. At the end of "Krusty Towers," it is implied that Mr. Krabs hires Patrick to work at his newly planned hospital (he addresses SpongeBob, Squidward, and Patrick as a group that they will be attending medical school), although whatever happened after this is unknown. In "Bummer Vacation," he took SpongeBob's job as an unpaid intern during his forced vacation. In "That's No Lady," Patrick, disguised as "Patricia," becomes the waitress of the Krusty Krab. In "Banned in Bikini Bottom," Patrick works as the bouncer to the secret Krusty Krab. In "Pat No Pay," he is forced to work at The Krusty Krab in order to pay for the numerous Krabby Patties he has eaten and failed to pay for. In "No Hat for Pat," Krabs wanted to have tourists eating at his restaurant but had no luck. He found Patrick standing outside doing nothing and wanting a hat, he applied for the job to advertise The Krusty Krab. He made no success but obtained his hat and started falling to the ground, bringing tourists and more customers. His falling made Krabs find more things to fall into and when the customers see that two were about to hurt themselves only Squidward did and stripped Krabs from his money earned thus firing Patrick.
Gary served as a waiter for the secret Krusty Krab in "Banned in Bikini Bottom." He also worked as a referee when a hockey team practiced in the frozen Krusty Krab in "Krabs a la Mode." He was also the "cleaner of the ick" in "Fungus Among Us." In "Shellback Shenanigans," Gary serves in sentry duty to prevent Plankton from infiltrating The Krusty Krab.
Charles worked at The Krusty Krab without Krabs knowing in "Welcome to the Bikini Bottom Triangle." While he was "holding down the fort," he somehow caught Plankton during Krabs and the Krusty Krew's absence.
This French cook from Fancy! came to the Krusty Krab during the Chef's Exchange Program in "Le Big Switch." As a professional gourmet chef, he was harsher and more practical than SpongeBob, much to Squidward's delight. His refusal to prepare meals unless his demands for expensive fancy essentials were met brought the Krusty Krab to bankruptcy; however, Mr. Krabs may have brought it on himself, due to his fear of spending more than he desired. Le Schnook returned to Fancy! as soon as his time in the Chef's Exchange Program was up.
Frank was once hired by SpongeBob, the Krusty Krab's temporary manager. In "Gullible Pants," Squidward told SpongeBob a false secret stating that Frank wanted a job as a fry cook. The latter gave him the job, and Frank thought that SpongeBob knows his secret, making him think that SpongeBob was threatening to reveal it. He did what the sponge says and cooked Krabby Patties as Squidward gives him more false secrets.
After replaced with Karen 2 by Plankton in "Karen 2.0," Mr. Krabs took Karen to The Krusty Krab after being thrown on the streets. Later, when Karen decided to forget about Plankton, Krabs hired her as the cashier, making Squidward the janitor. Not long after, Karen 2 and Plankton visited The Krusty Krab where the two computers had a fight, Karen reigning supreme. After having a brief shut down, Plankton took Karen back to the Chum Bucket, thus putting Squidward back into his position as cashier, in which Krabs used the remains of Karen 2 to dress Squidward up to attract more customers.
Mrs. Puff worked at The Krusty Krab only in "Summer Job." She accidentally smashes through the front door of the Krusty Krab with her boat and Mr. Krabs decides to have her work unpaid until the damages are fixed. Mrs. Puff mainly takes over Squidward's job at the register and Krabs assigns SpongeBob to look over her. Having enough of SpongeBob bossing her around, Puff storms out of The Krusty Krab and prepares to drive off, but a policeman arrests her for littering (she just threw SpongeBob's note on the ground).
Jim was The Krusty Krab's original fry cook before SpongeBob. He created the Jim Patty, which proved to dominate the Krabby Patty. However he was not happy that Mr. Krabs was paying him too low, so he quit his job (which presumably cost Mr. Krabs a lot of money due to his invention of the Jim patty and how he went to work in other restaurants). He became rich and visited The Krusty Krab in "The Original Fry Cook" in which time seems to have made him forgive Mr. Krabs and his cheapness.
In "Truth or Square," Squidward had a flashback remembering his life before SpongeBob and Patrick moved in next door. He seemed to be very happy and to have a similar personality to SpongeBob. Not SpongeBob (as Squidward imagined his name) seemed to hate his job like the modern Squidward and was possibly annoyed by him like Squidward is with SpongeBob. He worked at The Krusty Krab after Jim and before SpongeBob. He was presumably fired and replaced with SpongeBob after he moved in. It is unknown if that is his real name or if he was remembered that way by Squidward to show that he was not SpongeBob.
Larry disguises as Mr. Krabs in "The Check-Up" so the Krusty Krab won't be shut down. He was also the temporary manager in "Larry the Floor Manager" while Mr. Krabs was on vacation.
Being cheap, Mr. Krabs consistently pays his employees extremely poorly, although the exact amount varies. In "Squeaky Boots," SpongeBob's paycheck consisted of an envelope of money. In "Dying for Pie," Squidward mentions that he gets paid at minimum wage. In "Bossy Boots," when Krabs tries to get rid of all the stuff he bought for the Kuddly Krab, he sells them to SpongeBob for 1 years salary. This includes music, carpet, furniture, and stuffed animals. In "Skill Crane," Krabs gives SpongeBob and Squidward their paychecks, which consists of an envelope of money for SpongeBob and a huge bag of quarters for Squidward.
In "Bummer Vacation," Mr. Krabs holds up a dime and SpongeBob says that is more than what he makes in a year. In "Squid on Strike," Krabs deducts from SpongeBob and Squidward's salary for "goofing off." In "Big Pink Loser," SpongeBob claims that he actually pays Mr. Krabs rather than being paid himself. In "One Coarse Meal," it is revealed that Krabs pays SpongeBob with fake money called "Wacky Bucks."
According to the Krusty Krab Training Video, employees work under the unfortunately named philosophy of "POOP" which stands for People Order Our Patties. This video also explains how employees are required to maintain personal hygiene, keep their work station tidy and free of droppings, and keep supplies clean and organized. Employees must also be prepared for an emergency situation and watch out for Plankton.
Annual Employee Report Card
Report cards are kept to record the progress of employees on their tasks or job. The requirements include:
Keeps Work Area Clean
Arrives at Work on Time
Does a Laborious Task for Supervisor
Keeps up on Hygiene
There is also inspection for the employees (as seen in the episode "Missing Identity"). To pass the requirements, an employee must complete the following requirements.
Must have name tag on
Must be clean
The Krusty Krab is one of the most popular restaurants in Bikini Bottom. The place is usually full of customers except during episodes that involve trying to attract them. There is usually a significant line at Squidward's register and occasionally leads outside the doors into the distance with no one being discouraged from waiting in it to acquire food.
The food is so popular in fact that several times when customers are made to wait on food, rather than complain or simply leave, they will riot, such as in "Whatever Happened To SpongeBob?". Customers sometimes SpongeBob and Squidward and even damaging the restaurant despite attacking the Fry Cook and waiter being the opposite of helpful in that situation.
During the period where The Krusty Krab had a drive thru the town turned into a parking lot since everyone tried to use it, never occurring to anyone to just get out of their car and go inside like normal.
In several episodes, The Krusty Krab is temporarily changed or even converted into a different restaurant entirely.
In "Bossy Boots," Mr. Krabs hires Pearl to work at The Krusty Krab during her vacation. With the help of SpongeBob, she changed The Krusty Krab into the "Kuddly Krab," a girly teen hangout restaurant which served only tea, fries and salad. The restaurant featured a colorful design and featured stuffed animals and other novelty decorations. Despite its popularity among teens, the Kuddly Krab suffered an overall decline in profits and Pearl had to be fired. Pearl reveals that she was actually trying to be fired, as the job cut too much into her social life. The Krusty Krab returned to normal, and SpongeBob bought all the decorations for one year's salary.
In "Squilliam Returns," Krabs let Squidward temporarily transform The Krusty Krab into a fancy 5-Star restaurant so that Squidward could impress his highly successful unibrowed rival, Squilliam Fancyson. The plan worked, until SpongeBob went insane because Squilliam asked what's his name and destroyed the restaurant.
In "Le Big Switch," a French "exchange chef" from the Fancy! restaurant becomes the cook at The Krusty Krab, and The Krusty Krab is transformed into a five-star French bistro, where Krabs is ecstatic because he can serve minuscule portions for very high prices, including a putrid dish which can only lose its stench by shredding gold on top of it. The French chef does this, much to Krabs' disapproval. Squidward is also very happy because SpongeBob became an exchange chef and went to the Fancy! restaurant where his Krabby Patties were a huge hit even though it was not the type of cuisine suited for the Fancy! restaurant. Eventually, The Krusty Krab bistro goes out of business and SpongeBob brings back all the Fancy! customers, who were demanding Krabby Patties from The Krusty Krab, returning the restaurant to normal.
In "Selling Out," Krabs sells The Krusty Krab to a corporate mogul named Howard Blandy and goes into retirement. The Krusty Krab is converted into the "Krabby O'Monday's," a family diner that had a pleasant atmosphere but in reality, generated synthetic Krabby Patties made of sludge by machine. When Mr. Krabs took a job there as a result of boredom, he discovers this secret and goes on a rampage, revealing it to the customers and destroying the restaurant. He then buys the destroyed Krusty Krab back from Blandy for full price.
In "Krusty Towers," Krabs transforms the restaurant into the "Krusty Towers," a multi-story hotel after staying at one and witnessing the outrageous prices that hotels can charge. The Hotel is destroyed when Patrick performs a cannonball into the swimming pool in his room, causing the tower to collapse, leaving only the original Krusty Krab.
In "Krabs a la Mode," the restaurant is converted into an indoor ice ring, and later a swimming pool, when Plankton's plot to turn down the thermostat and freeze The Krusty Krab backfires.
In "The Krusty Sponge," Krabs, after receiving a review praising SpongeBob, transforms The Krusty Krab into a SpongeBob-themed restaurant called the Krusty Sponge. However, the soiled yellow "Spongy Patties" made Krabs be arrested. Krabs bribes the judge to excuse him by having Squidward give him rides on the train which was built around the restaurant.
In "SB-129," The Krusty Krab is shown to in some form still be in business two-thousand years into the future. Like everything else in the future, the restaurant is entirely plated in chrome.
In "Drive Thru," Mr. Krabs added a Drive Thru, but after this episode, the Drive Thru is never seen again. Also, the sides of the restaurant are wooden without the netting or glass as shown in every other episode.
In "Goodbye, Krabby Patty?," Mr. Krabs replaced the old Krabby Patty with a sand-made frozen alternative, converted the Krusty Krab from a restaurant to a museum, fired SpongeBob as fry cook and rehired him as tour manager, fired Squidward without rehiring him, and placing a large factory, dubbed The Krusty Factory behind the former restaurant. However, all these changes are reverted at the end of the episode.
In "The Krusty Slammer" Mr. Krabs ask his employees that he's turning the Krusty Krab into a prison system since he captured Plankton as a prisoner. Until SpongeBob gives Krabby Patties to the other prisoners which makes Mr. Krabs furious which he let the prisoners free. Until the next day, the other prisoners are back to there cells. Which he's now arrested for letting the prisoners free. And now he's Plankton's prisoner.
In "The Krusty Bucket" when PlanKrab came into the Krusty Krab he changes and takes over the whole entire restaurant, kicks out Mr. Krabs, and becomes manager of the Krusty Bucket.
Plankton attempted to walk right into The Krusty Krab and steal the formula. He tripped and made himself look helpless which made the public send Krabs to court. His new attempt was to sue Krabs for the formula. SpongeBob, impersonating as a lawyer, made sure that Plankton reveals his true intentions, resulting in another plan foiled. The public and jury turned against Plankton and labeled Krabs not guilty but cheap in the episode "Krabs vs. Plankton."
In the episode "The Krusty Sponge," Krabs was arrested for serving poisoned food. The entire town of Bikini Bottom was against him. Luckily, the judge was a SpongeBob fan, so he reconsidered and did not send Krabs "down the river." Instead, he would return the restaurant to its normal ways, and the judge would get a ride on the Fun Train as many times as he likes.
Krabs was arrested for avoiding to pay for a product by stealing. The judge, Horace A. Whopper, decided that he will give away free Krabby Patties all day afterward. SpongeBob gives away Krabby Patties served by the dozens as Krabs screamed in horror while watching. This most likely ruined the profits as seen in the episode "Patty Caper."
It has also been shown that due to Mr. Krab's utter cheapness and greed that he is willing to violate many workers' rights laws. This eventually got up to the point where it was almost as if it was slave labor at The Krusty Krab. It has been shown numerous times such as in "Fear of a Krabby Patty" and "Chum Caverns" that he has kept employees and customers captive at The Krusty Krab. It has also been shown that he pays them far below minimum wage ("Squid on Strike" and "Bummer Vacation"). He also has shown to physically abuse his workers (mainly Squidward) in episodes such as "The Krusty Sponge" where he has Squidward give a judge a ride on a train (that was pedal-powered) while at the same time having Squidward whipped like cattle. Also in "Squidward in Clarinetland" where he did not provide Squidward with storage space for his clarinet.
Mr. Krabs has also violated several health code and safety regulations. For example, in "Greasy Buffoons", he deliberately served food covered in grease to his customers in order to compete with Plankton, who was also serving grease-covered food. It got to the point that SpongeBob had to call the health inspector. In "The Krusty Sponge", Mr. Krabs served "Spongy Patties", which were basically Krabby Patties that became spoiled. Everyone who ate them turned yellow with green spots and developed aching, distended stomachs.

The location of the Krusty Krab relative to SpongeBob's house is not always the same. In the episodes "Help Wanted," "Plankton!," "Pickles," "Suds," "Hooky," "Missing Identity," and "Lost in Bikini Bottom" SpongeBob goes to the right of his house and passes Squidward's and Patrick's houses. In almost every other episode where the location of the Krusty Krab is relative to SpongeBob's house, he goes to the left (the list of episodes would take such a long time to type, but they also include the video game Revenge of the Flying Dutchman). Mr. Krabs is too cheap to buy the pieces of property to place a Krusty Krab when it is destroyed.
The address of the Krusty Krab is 831 Bottomfeeder Lane. In "Walking the Plankton," a letter is being delivered to The Krusty Krab in the beginning of the episode. If one pauses the episode at the right time, the address can be read.
Inside Mr. Krabs' office, one of the flags represents the flag of Scotland.
The fifth flag hanging outside the Krusty Krab resembles the flag of Ukraine turned sideways.
There are some episodes where the people are shown eating Krabby Patties even though SpongeBob is not in the Krusty Krab. This shows that either Squidward or Mr. Krabs know how to cook Krabby Patties or they simply get them from the Patty Vault that appears in "Just One Bite."
In the scene where SpongeBob washes his hands in the "Krusty Krab Training Video" (also seen in "Karate Choppers" and "Kenny the Cat"), there is a poster that says "Please wash your fins." Under those words, there are words in Spanish that say "Wash the fins" (Lave las aletas).
The alarm siren in the Krusty Krab has the exact same sound as the one used in The Shawshank Redemption.
Speaking of which, Clancy Brown is the portrayer of Capt. Byron Hadley, in the afformentioned film.
The Krusty Krab's doors have been shattered repeatedly throughout the episodes, but later in the episodes, the doors are fixed.
In "SB-129," it is revealed that the Krusty Krab is closed on Sundays while in "Squid's Day Off," it is open.
In "Nasty Patty," the sign is on the right side of the restaurant and has the name written in green neon lettering.
The Krusty Krab's largest order was 10,000 Krabby Patties, ordered by Plankton (who introduced himself as "Dr. Peter Lankton") in the episode "Fear of a Krabby Patty," in order to exhaust SpongeBob, so he could reveal to him the secret Krabby Patty formula. Luckily, SpongeBob did not reveal it.
According to SpongeBob Moves In!, the Chum Bucket and the Krusty Krab were opened on the same day. However, the Chum Bucket that appears in the series is not the original Chum Bucket. The Chum Bucket in the series opened sometime after SpongeBob joined the Krusty Krew.
Throughout the whole show, the Krusty Krab has appeared in all first episodes per season, with exception of Seasons 6, 9, and 10.
There is a real-life replica of The Krusty Krab located in Ramallah, West Bank, Palestine. Also in Mexicali,
, actually exists a restaurant called "El Krustaceo Burger" (Krusty Burgers in English) which looks the same as The Krusty Krab, including identical locations like Mr. Krabs' office, and the meals have names similar like the ones on the Galley Grub.
As of 2019, both real-life replicas of The Krusty Krab had been closed permanently.
All of the main characters have worked for the Krusty Krab at least once in the series.
