The movie follows SpongeBob SquarePants (voiced by Tom Kenny), a cheerful and optimistic sea sponge who works as a fry cook at the Krusty Krab restaurant in the underwater city of Bikini Bottom. When the nefarious Plankton (voiced by Mr. Lawrence), the owner of the rival restaurant the Chum Bucket, steals the secret formula for the Krabby Patty, Bikini Bottom is thrown into chaos.
Determined to save the Krusty Krab and recover the stolen formula, SpongeBob teams up with his best friend Patrick Star (voiced by Bill Fagerbakke) and sets out on a quest to Shell City, a dangerous location where they believe the formula has been taken.
