Johnny Mushroom and the Kingdoms is a punk rock band, created by Mario and Luigi that first premiered in "A Band that is better than the Jonas Brothers!". The band later reappeared in "Who is Scott Masterson?". The band was the focus of "Guess who's not invited...again". In Operation: Blind Storm, Evil Dane offered to be the band's manager, which Mario and Luigi accepted (they were bribed with coins) and later created "Let the Goombas Hit the Floor." In the episode "JMK FOREVER!", they return to create an original song.
