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 makes it his mission to become normal; SpongeBob wakes to find that everyone in Bikini Bottom is gone.

Patrick and SpongeBob learn to tie their shoes; Squidward is in charge of the Krusty Krab.

Sandy Squirrel is homesick; Plankton tries to get SpongeBob to be mean.

SpongeBob and Patrick create their own zoo that is made entirely of bubbles; the Krusty Krab goes under emergency quarantine, but no one knows who is carrying the mysterious illness.
