This is a game set within the SpongeBob SquarePants mythos, but plays similar to a Smash Brothers game. Up to four players can play at once either locally or online. The players can choose from among several of the cartoon's familiar characters. There are 10 levels through which the players will advance. The object of each level is to be the first player to collect 99 pairs of underpants. The players can attack each other in order to disrupt each other. There are power-ups to collect and other obstacles to avoid. Single-player features Solo Quest mode and Time Attack mode.
