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.

Mr. Krabs must pretend that he is a pirate when his grandfather comes to visit; SpongeBob discovers that Squidward is a member of a secret society and decides that he wants to join.

Frustrated that he's seen as cute instead of evil, Plankton builds a robot to punish anyone who says "aww!"; Patrick crushes the mailman, so he and SpongeBob deliver the mail around Bikini Bottom.

Squidward spends a day at the laundromat with his fellow Bikini Bottomites; SpongeBob and Patrick must track down Old Man Jenkins' prized worm hog.

SpongeBob, Patrick and Squidward are swept away to a remote tropical island by a giant wave.
