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.

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.

Stardom goes to SpongeBob's head after he appears in Krabs' low-budget commercial; Squidward becomes impoverished.

SpongeBob is forced to go back to the milkshake academy when he learns that his milkshake license has expired; SpongeBob and Patrick must take care of Squidward when he reverts to being a baby.

SpongeBob suspects Patrick of stealing his jellyfishing net; SpongeBob builds a ventriloquist dummy modeled after Squidward.
