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 falls asleep on the bus and ends up in a town full of Bikini Bottom doppelgängers; after Squidward loses his memory, he adopts a new tough guy persona.

Plankton closes the Chum Bucket and moves to a new town, but Mr. Krabs suspects he is still up to no good; when SpongeBob accidentally picks up Neptune's magic trident, there is no telling what trouble he may cause.

Plankton steals Sandy's pelt to impersonate her; Plankton tries to launch himself into Mr. Krabs' head and misses his target.

SpongeBob and Patrick take Squidward jellyfishing; SpongeBob is a victim of Plankton's scheme.
