A square yellow sponge named SpongeBob SquarePants lives in a pineapple with his pet snail, Gary, in the city of Bikini Bottom on the floor of the Pacific Ocean. He works as a fry cook at the Krusty Krab. During his time off, SpongeBob has a knack for attracting trouble with his starfish best friend, Patrick. Arrogant octopus Squidward Tentacles, SpongeBob's neighbor, dislikes SpongeBob because of his childlike behavior.
A new secret Krabby Patty formula has disastrous results for Bikini Bottom, and only SpongeBob can save the day; Mr. Krabs and Plankton have to take boating school classes.
Patrick inducts SpongeBob into his prestigious society of dullards and doofuses; Patrick takes his grime to a new extreme, playing around in so much trash that he becomes unrecognizable.
When Mr. Krabs gets in trouble for littering, he makes SpongeBob and Squidward clean up Bikini Bottom; a sea bunny ravages Squidward's garden, but SpongeBob thinks it's cute.
Plankton invents a machine enabling him to switch lives with Mr. Krabs; SpongeBob volunteers for lifeguard duty.
