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.

Patrick befriends a sea monster; SpongeBob and Squidward search for answers when things begin to disappear from Bikini Bottom; Madame Hagfish puts a hex on the Krusty Krab; SpongeBob and Patrick search for a legendary drain on the ocean floor.

Patrick invents a new board game and invites SpongeBob, Sandy and Squidward to play it with him; after accidentally flushing Mr. Krabs' safe, SpongeBob and Squidward must go into the sewers to find it.

Plankton tries to befriend Squidward so he can get the Krabby Patty formula; the citizens of Bikini Bottom clamor for Patrick's artwork after an art critic praises him.

Sandy Cheeks takes a rocket ship into space; Mr. Krabs gives SpongeBob a pair of squeaky boots.
