A storm current has disrupted a shipment of the undergarments of King Neptune's underwear, spreading them across the ocean floor. Neptune has called upon his subjects to collect the lost undergarments, with a reward offered to the one who collects the most pairs of underwear.
Players progress through 9 levels of play by collecting 99 pairs of underwear in each level. Playable characters include SpongeBob, Patrick, Mr. Krabs, Plankton (unlockable), and Sandy. Levels are populated by jellyfish, who can swim away with pairs of underpants. These stolen underpants can only be retrieved by attacking the jellyfish, and failure to attack at the right moment results in an electrical shock. The jellyfish can be purple, blue (these ones steal the underpants), red, or yellow.
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 can be used 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 a score of 55 and a score of 3.5 out of 5 on GamesRadar.
