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.

SpongeBob and Squidward become stranded in the desert while delivering a pizza; SpongeBob loses his pineapple home.

The friends become unstoppable after Sandy teaches them karate; before long, the entire town learns the martial art and joins the action.

Patrick becomes smart after he gets hit on the head; Sandy's experiment causes SpongeBob and Squidward to meld into one body.

SpongeBob micromanages an all-out shindig for the denizens of Bikini Bottom.
