One morning, SpongeBob looks at his calendar and realizes that it is the first day of summer, and he gets excited. When he goes to work, he sees Mr. Krabs even more excited for summer. SpongeBob asks him why, and he says that on summer vacation, children go around spending money, and the Krusty Krab will get more profits through kiddie meals, which he raises the price of from $1.99 to $4.99. However, he sees that the children are all at a new playground, and decides to make a playground of his own called Krabby Land.
At work the next day, Mr. Krabs reveals the grand opening of Krabby Land, which he proudly built himself. Krabby Land is a little more than a dopey-looking assembly of cheap and dangerous attractions. The children are horrified, yet speechless with disappointment, but Mr. Krabs gives them coloring books/liability waivers and says that whoever hands theirs back gets to meet "Krabby the Clown." He tells them that the clown will come soon, and tells SpongeBob to stall the kids while he counts the money.
SpongeBob pretends to be Krabby's sidekick, "the Krabby Patty Burglar," but the children hate him. He accidentally injures himself while trying to amuse them by blowing bubbles and getting soap liquid in his eyes, which makes the kids laugh. He realizes that the kids like it when he is in pain, and begins intentionally harming himself, even hiring two thugs to torture him by feeding him lima beans.
After a while, SpongeBob goes to Mr. Krabs, who is sorting through a large stack of money, and tells him that he cannot stall the children anymore, being horribly beaten and missing limbs. Mr. Krabs tells SpongeBob he is being selfish and tells him to "get back there and stall," but upon seeing SpongeBob's limbs flying around, he fears that his windows will be smashed, so he tells him to let the crowd of children enter the restaurant for Krabby the Clown's arrival. Excited, the children and SpongeBob rush in front of Mr. Krabs, who welcomes Krabby the Clown. However, it turns out that Mr. Krabs turns around and immediately puts on a bow tie and a blue-painted tomato on his nose, and does a cheap imitation of the clown. He then walks back into his office, leaving the children and SpongeBob jaw-dropped in confusion. This latest rip-off is the last straw for the children.
An extremely disappointed SpongeBob confronts Mr. Krabs, expressing his disdain for such a rip-off. Mr. Krabs undresses from his costume and finally says to SpongeBob that he does not care about the children, but for their money and is willing to do whatever it takes to get their money, and even calls the kids stupid and foolish enough to be the victims of his scam. He then taunts SpongeBob for being unable to stop him in time by saying twice, "Survival of the fittest."
Mr. Krabs tries to go to the bank with the money he has made, but he is confronted by an angry mob of children who have overheard his confession and are planning to punish him. Mr. Krabs, realizing that he is about to be punished and has given the kids his confession which was not taken well, tries to reconcile, but fails as the kids charge, beat him up, and destroy the playground.
Inside, SpongeBob is bewailed that he will never learn the true meaning of summer. Monroe then calls SpongeBob over about the summer miracle, where the kids take back all their money and distribute it back to themselves. SpongeBob guesses it is the true meaning of summer, but he asks Squidward where Mr. Krabs is, who is missing out the summer fun. The scene cuts to Mr. Krabs, tied on fours between wooden poles, who warns to return his "green stuff" and begs for freedom. However, the thugs, paid by the children for his swindling, reply to him with a can of lima beans and a truckload of them, causing him distress by the torture like what SpongeBob did earlier — only to learn not to underestimate the kids.

- This is the second episode where SpongeBob calls Gary "Gare-Bear," after "Krab Borg."
- This is the fourth episode where SpongeBob gets ripped in half. The previous three were "Texas," "Procrastination," and "I Had an Accident."
- This episode was foreshadowed in "Squid on Strike" when SpongeBob holds up a sign that reads "Krusty Krab Funfair" due to mishearing Squidward, which attracts a line of customers who think there is an amusement park at the Krusty Krab.
- The title card is shown on a small poster during the middle of the episode.
- In SpongeBob Comics #52, there is a comic strip titled "Krabbyland." The only difference between that comic title and this episode's title is that the comic title combines the words "Krabby" and "Land" into one word.
- Krabby Land is a spoof of McDonaldland and the McDonald's play places. Krabby the Clown is a spoof of Ronald McDonald, while the Krabby Patty Burglar is a parody of the Hamburglar.
- The motto of Krabby Land, "Where a kid can have fun-for the right price.", is a reference to Chuck E. Cheese's motto, "Where a kid can be a kid."
- When Krabby Land is first seen, the structure is approximately twice as tall as the Krusty Krab, with the resemblance of medieval architecture. But when Mr. Krabs unveils it, it is much shorter than seen previously.
- In the end, the wrinkles on Squidward's head disappear.
- When the line of people is seen before zooming into Krabby Land, most or perhaps everyone in line are adults or adult height.
- Also, when Mr. Krabs tries to leave the Krusty Krab to go to the bank, the kids are much smaller than they were in the previous scenes. When they are seen getting their money back, they are back to their usual sizes.
- On the Sponge for Hire DVD-credits, this episode is listed as "Krabbyland," combining the two words into one.
- SpongeBob wears a red mask around his eyes when he blows an irregular shaped bubble. However, when the bubble pops and the bubble water spills onto his eyes in the close-up view, the mask is gone.
- Just when SpongeBob ends the monologue "They enjoy other people's misery.," his voice slightly fades from the echoing sound to the normal sound and his mouth unexpectedly does not move.
- When Squidward replies to SpongeBob when he says that he thought what Mr. Krabs said was the true meaning of summer for a long time ago, he replies, "You mean this morning?"
- This is false, considering SpongeBob walked back to work after the playground "infiltration" with Mr. Krabs.
- When SpongeBob visits Mr. Krabs' office, the door on the side shows a hallway that cannot possibly even fit in the Krusty Krab instead of the kitchen.
- When Mr. Krabs is watching kids with his spyglass, he drops it, but in another scene, there is no spyglass on the ground.
- When SpongeBob falls into the box of bowling balls and the kids are laughing at him, in the group of children there are two Monroes, one with a hat and one without.
- When SpongeBob pulls out the bubble soap and wand, his eyelashes are seen on his red mask
