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.

Mr. Krabs manufactures Krabby Patties on an industrial scale, but it drives a wedge between SpongeBob and Patrick.

Plankton tells Patrick he's his conscience so he can convince the wooden-headed star to steal him a Krabby Patty; when Mr. Krabs puts in an open kitchen, SpongeBob gets stage fright and has to invent a new persona.

SpongeBob tries to find a way to get Squidward to visit him at his home; SpongeBob must search for a new pair of pants after his square pants shrink in the dryer.

Plankton joins the League of E.V.I.L.; SpongeBob and Patrick take Squidward on a plane to a tropical resort.
