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's house becomes infested with a mail-order flea circus meant for SpongeBob; Squidward fakes being sick to get out of work, but his agony only begins when SpongeBob arrives to care for him.

SpongeBob and Patrick accidentally board a ship full of prisoners; SpongeBob and Patrick find themselves left behind on one of Sandy's extreme wilderness expeditions.

Gary has a pet translation collar, and he's talking up a storm; when a small clown gets left behind by the circus, SpongeBob takes the hapless harlequin under his wing.

SpongeBob's friends must search for him when he develops amnesia and goes missing.
