It replaced Squidward Chat and probably also replaced The Guitar Lord too. From the one episode shown, it mainly consisted of the Guitar Lord playing his guitar with SpongeBob playing the electric piano and Patrick playing the drums, Sandy line dancing, Pearl cheerleading, Mr. Krabs advertising the Krusty Krab in mid-air, all while being pelted by blasts from Plankton's "death ray."
