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 prankster dad visits and brings all sorts of gags with him, much to Squidward's annoyance; Plankton tries to get a taste of the secret formula by attaching himself to SpongeBob's tongue.

Plankton's giant Chum Bucket glove runs wild in town, but SpongeBob has a handy friend to help them out; SpongeBob takes his first break ever at work.

SpongeBob sacrifices his perfect day to help his friends; Patrick gives SpongeBob his most-prized possession.

After a freak jousting accident, SpongeBob and Patrick are transported to a medieval version of Bikini Bottom.
