GameplayPatrick Star, Eugene H. Krabs, Sheldon J. Plankton, and Sandy Cheeks. Levels are populated by jellyfish, who can swim away with pairs of underpants. These stolen underpants can only be retrieved by attacking the jellyfish, failure to attack at the right moment results in an electrical shock. Most pairs of underpants are scattered around levels, though several are hidden in objects such as pipes and boxes which must be destroyed. Power-ups such as a magnet to draw in nearby bloomers can be collected throughout the levels; though, some can have negative effects such as reversing the controls.
- The game received mixed to negative reviews from critics due to the confusing level design. Metacritic gave the game 3/5, IGN ranked it 4.7/10, and GamesRadar gave it a 3.5/5.
- Some of this game's soundtrack is reused from the previous game, Spongebob Squarepants: Creature from the Krusty Krab]].
