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.

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.

SpongeBob volunteers to baby-sit; SpongeBob and Patrick volunteer as guards at the museum, while Squidward attempts to hang his painting unnoticed.

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

Patrick gets his license and wins a car; a document reveals that Patrick is next in line to become a king.
