Plankton using a pair of robotic arms to lift up and get away with a Krabby Patty.
The following is a list of schemes used by Sheldon J. Plankton to steal the Krabby Patty secret formula and/or put the Krusty Krab out of business. Most of Plankton's plans come from Karen, but he usually takes all the credit. Note that all such schemes with the exception of Plan Z and Plan 3,087 have failed.
First movie[]
- Plans A-Y - These are all the plans in 25 folders that Plankton had employed before, which all had failed. He thinks he has exhausted every plan until Karen reminds him that there is one more letter in the alphabet for him to try. On November 12, 2004, SpongeBlogger (part of The SpongeBob SquarePants Movie marketing campaign's Nickelodeon support)[1] had them listed:
- Plan A - "Request that Krabs relinquish Secret Krabby Patty Recipe."[2]
- Plan B - "Stealthily remove Secret Recipe from Krusty Krab grill. Stealthily remove self from Krusty Krab. Quickly."[2]
- Plan C - "Give dim-witted fry cook shiny golden spatula. Convince dim-witted that tomorrow is my birthday. Convince dim-witted fry cook that we are friends, and friends give friends presents on their birthdays. Convince dim-witted fry cook to give me the Secret Recipe."[2]
- Plan D - "Enter slumbering fry cook's brain and engage Total Control Device. Instruct SpongeBob to deliver Krabby Patty to the Chum Bucket for examination."[2]

- Plan L - "Win unwitting fry cook in poker game from rival Krabs. Will require cheating. Fake NICENESS so fry cook will return kindness with Krabby Patties."[2]
- Plan M - "Engage the Switch-Lives-Just-To-Know-What-It's-Like-O-Mogrifier and trade places with Krabs."[2]
- Plan N - "Attend absorbent fry cook's party. Play putrid party game. Convince Krabs that the game card he receives says, 'Discuss the Krabby Patty Secret Recipe.'"[2]
- Plan O - "Construct cockroach costume. Don masterful disguise and enter Krusty Krab undetected. Stealthily remove Secret Recipe."[2]

- Plan W - "Construct mechanical limbs for Krabby Patty. Mount Krabby Patty. Ride 'em, Krabby Patty."[2]
- Plan X - "There never was a Plan X"[2]
- Plan Y - "Plan Y was...Someone hacked my list!!!!"[2]
- Plan Z - The one plan that Plankton missed. This one was the most evil of the other plans, and even lemon-scented according to Plankton himself. He used this to steal King Neptune's crown, and put the blame on Krabs so King Neptune can freeze Krabs, then Plankton gets his hands on the formula, and brainwashes Bikini Bottom's residents. However, he does not count on SpongeBob and Patrick, and after they retrieve the crown from where Plankton hid it - with some help from David Hasselhoff - the two bring it back in time. When Plankton orders his minions to annihilate SpongeBob, he destroys their helmets via heavy-metal music. All the freed Bikini Bottomites run him over, and he is then arrested for turning Bikini Bottom into a living nightmare by enslaving it and framing Mr. Krabs.
Second movie[]
At the beginning of the movie, Plankton tries to steal the formula with a plane, tank, and robot. These all fail. This Plankton is soon revealed to have been a robotic dummy all along and the real Plankton is hidden inside a penny. Plankton, on the phone with Karen, infiltrates Mr. Krabs' safe and replaces the formula with a fake bottle. SpongeBob comes into Mr. Krabs' office and finds Plankton stealing the formula. They fight over the formula and suddenly, it disappears into thin air. Later, Plankton decides to go into SpongeBob's brain thinking that he is lying about not remembering it, but it once again backfires after Plankton is fed up with sweetness inside SpongeBob's head.
Third movie[]
Plankton sneaks to the Krusty Krab at night, takes a small piece of a Krabby Patty SpongeBob left on the register, and analyses it, copying the secret formula. However, it backfires once Plankton accidentally falls in the fryer, burning the copy of the formula. Later, after he finds out that SpongeBob is the one who ruins his plans, he takes the advantage of his snail Gary taken to King Poseidon and allows SpongeBob and Patrick to ride to Atlantic City, hoping that they will never come back.
The plan actually works with Mr. Krabs falling in disgrace and giving the formula to Plankton but he feels guilty for what he did and decides to help him rescue SpongeBob, Patrick and Gary from King Poseidon.

- "Shopping List" - Plankton follows SpongeBob and Sandy around and steals the bag of ingredients in hopes of making Krabby Patties. However, this fails when it was revealed that the ingredients that SpongeBob and Sandy got were fake while Mr. Krabs has been hiding the real ones. So as a result, the Chum Bucket exploded after Plankton makes the fake recipe.
- "Patnocchio" - Plankton poses himself as Patrick's conscience in order to get a Krabby Patty so he could figure out the formula. This fails when Patrick's real conscience arrives and tells Patrick that Plankton's a fake, which results in the two stepping on him.
- "Plankton Paranoia" - After successfully helping SpongeBob and the gang put Mr. Krabs' insane behavior to a stop with a surprise party, Plankton sees the bottle with the secret formula left on the table. When he opens it, he finds a lit dynamite in the bottle and it explodes, destroying the Chum Bucket in the process.
- "Call the Cops" - Plankton steals the formula again, but he immediately gets taken away by the police and the formula is put in the evidence room. He teams up with Patrick to escape his cell and head to the evidence room to get the formula back. This fails when Mr. Krabs snatched it from him, causing a massive brawl. Eventually, they all get arrested and placed in the same cell Plankton is in.
- "Surf N' Turf" - Plankton steals the formula off-screen after SpongeBob hands Sandy the bottle it was in. This fails when SpongeBob snatched it back from him.
- "The Grill is Gone" - When Plankton heard that a group of obnoxious and immature children stole the Krusty Krab grill and made it into a racing cart, he decided to participate in the race in hopes of getting the formula. This fails when Mr. Krabs flicked Plankton off the racing track.
Season 12[]
- "The Krusty Slammer" - Plankton vandalizes the entire town of Bikini Bottom by painting graffiti messages about Mr. Krabs as an attempt to attract people. However, his plan fails when he gets arrested by the police. But towards the end, it's Mr. Krabs who gets arrested and ends up being tortured by Plankton. This is one of the few episodes ending with Plankton getting the last laugh.
- "King Plankton" - Plankton attempts to take over SpongeBob's aquarium filled with sea monkeys, but it backfired when they rebelled against him.
- "Plankton's Old Chum" - Plankton tricks SpongeBob into hiding rotten chum all over Bikini Bottom when he told him about Chum Day, a fictional holiday he just made up and a holiday similar to that of Christmas. It seemed to have worked well at first, until the Health Inspector gives him a fine and forces him to eat all of the rotten chum.
- "The Krusty Bucket" - Plankton tries to create a clone using the DNA samples of himself and Mr. Krabs' hair to steal the formula. However, his plan backfired when the clone takes over both the Krusty Krab and the Chum Bucket.

- "Handemonium" - Plankton brings the Chum Bucket glove to life in order to beat Mr. Krabs in an arm-wrestling match and steal the Krabby Patty formula. Although he succeeded in defeating Mr. Krabs, his plan of stealing the formula backfired when the glove went on the loose and attacked Bikini Bottom.
- "The Ghost of Plankton" - He turns into a ghost using a ghost extracting machine to steal the formula, with the help from the Flying Dutchman, but fails due to the fact that the bottle was too solid to float through the safe.
- "The Hankering" - When Plankton learned about Mr. Krabs' craving on chum, he attempts to trick him into giving away the secret formula in exchange for a lifetime supply of chum. Plankton nearly succeeded until he and Mr. Krabs get into a massive brawl which led to the secret formula sinking into the chum. Plankton attempts to retrieve it by swimming through all the chum. Mr. Krabs assumed that his business is ruined, but SpongeBob reminded him that Plankton is tiny and it would take him forever to swim through the chum to get the formula. In the end, Mr. Krabs managed to save the formula and foil Plankton's plan by eating all the chum, which eventually ended up swallowing Plankton in the process.
Season 13[]
- "A Place for Pets" - After everyone starts to make animals costumes so they can eat at the Krusty Krab, Plankton goes into his pet, Spot, so that he can get the formula. However, Plankton is digested by Spot and when he comes out, he only has his eye left.
- "Lockdown for Love" - Plankton gets Patrick to dressed up as him so that he can sneak out to the Krusty Krab without Karen noticing.

This causes Karen to become angry at Plankton for tricking her and she immediately deletes the secret formula.
- "C.H.U.M.S" - At the beginning of the episode, Plankton analyzes a path through the Krusty Krab's air ducts to steal the formula. However, SpongeBob is washing the restaurant with a hose, and he accidentally sprays the hose at Plankton, making him end up in the sewer. Later on, he meets the C.H.U.M. organization, of which worships him, and he uses them to convince Mr. Krabs to give him the formula. However, this plan fails when SpongeBob accidentally hoses down the giant chum monster.

Dirty Bubble traps SpongeBob, Squidward, and Mr. Krabs with a distraction and Plankton steals the formula, but E.V.I.L finds out that the formula is just a recipe for a sandwich.

Before Petunia can get back into the flower shop, Squidward (not knowing Petunia is actually Plankton) stalls her and tries to propose to her. The timer goes off and the bouquets explode, exposing Plankton's disguise and his plan foiled.

Trivia[]
- A deleted scene from "Sandy's Rocket" seen only in the chapter book based on the episode involves Plankton tries stealing the formula from the Krusty Krab during the night, only to be caught by SpongeBob and Patrick.
- Ironically, Plankton's plans that do not involve stealing the formula are usually the ones that are close to success.
- There have been times where his aim is not to steal the formula, as in "Atlantis SquarePantis," he aims to rule Atlantis and kill the fellow tourists. SpongeBob SquarePants (musical) and "The SpongeBob Musical: Live on Stage!" are another example.
- Although there are simpler alternatives for stealing the formula, Plankton always chooses completely illogical and complicated plans. For example, in "Plankton's Army," he uses a robot to order coral bits and jumping out of the dollar to surprise Mr. Krabs instead of programming the robot to order a Krabby Patty.
- "20,000 Patties Under the Sea," "Banned in Bikini Bottom" and "Free Samples" are the only episodes where SpongeBob is unaware of Plankton's scheme throughout the episode.
