SpongeBob SquarePants teams up with Plankton to recover Mr. Krabs' coveted Krabby Patty formula in Truth or Square. The platform-style action has you controlling the yellow cartoon character through an assortment of familiar locales, including downtown Bikini Bottom, the Krusty Krab, the Jellyfish Fields, and Rock Bottom, while advancing across 12 levels. With the help of Plankton's memory machine, SpongeBob will also revisit ten of the "happiest moments" in his underwater life. It is hoped that by revisiting his past, SpongeBob will remember where he placed the secret formula. In addition to jumping and spinning, SpongeBob can morph into a sledgehammer, water gun, and explosive cannon to defeat rivals. Both the Wii and Xbox 360 versions of the game feature cooperative support for two players.
