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.

Squidward takes a new job as manager of Weenie Hut Jr's; Squidward gets trapped on his way to return a nearly overdue library book.

Gary is given a set of limbs to keep up with SpongeBob, but soon makes his owner look sluggish; Plankton practices ruling the world by shrinking himself and declaring himself king of SpongeBob's aquarium.

When a prehistoric sponge is unfrozen, he causes chaos all over town and only SpongeBob can communicate with him; when a flock of clams descends on Bikini Bottom, SpongeBob has to get them out before they ruin the whole town.

Squidward swallows his clarinet reed; Patrick disguises himself as a girl.
