Upon arriving at the factory, a robot sucks up all the Krabby Patties, and Patrick, unintentionally, in the process. During the opening credits, SpongeBob SquarePants and Patrick Star deliver a truckload of several million Krabby Patties to a Krabby Patty processing and toybot factory. Calamitous states that by feeding fairies Krabby Patties, they can emit a magical gas that, combined with the ghost energy, can be used as a form of fuel for his army of 'Toybots,' evil toy duplicates of abducted and scanned heroes.

The game opens with Jimmy Neutron's nemesis, Professor Calamitous, being a contestant on a reality show called 'The Biggest Genius'. Players journey through Bikini Bottom, Amity Park, the Ghost Zone (GBA version only), Fairy World, Pupununu Village (handheld version only), Retroville (handheld version only), and Calamitous' Lair (console version only), as well as the Toybot Factory, which is divided into multiple segments.
