When the villain known as Dirty Bubble kidnaps geriatric super-guys Mermaid Man and Barnacle Boy, it's up to SpongeBob SquarePants to mount a daring rescue of his favorite heroes. Though a series of 3D platform levels set in SpongeBob's hometown of Bikini Bottom, players must explore hidden areas and defeat dangerous enemies. It's lucky that "The Yellow Avenger" got hold of Mermaid Man's utility belt, as special powers such as "Super Strength," "Super Speed," and "Summon Sea Creatures" are sure to come in handy along the way.
