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.
Bubble Bass and the dirty bubble team up to become Bikini Bottom's nastiest nefarious nuisance; Plankton joins the SquarePants family in the hope of becoming closer to SpongeBob and the secret formula.
SpongeBob and Mr. Krabs turn an old submarine into a mobile Krusty Krab; SpongeBob and Patrick engage in an epic battle over cleanliness.
When the Krusty Krab is left filthy, a magical fish teaches SpongeBob how to keep surfaces looking spiffy, lickety-split; SpongeBob is recruited to cook in the big leagues, but first, he must prove his worth in the test kitchen.
SpongeBob's friends must search for him when he develops amnesia and goes missing.
