Tommy Fungus and the Dungeons was a band, formed by Wario and Waluigi after they were kicked out of Johnny Mushroom and the Kingdoms by Scott Masterson in "Who is Scott Masterson?". In the episode, Wario and Waluigi hoped to become more popular than Johnny Mushroom as revenge for being kicked out. Unfortunately, only Waluigi's girlfriend Walgina showed up for auditions, and they were forced to accept her in the band despite her poor singing skills and Wario's overall dislike for her. After FedEx arrived with their instruments, they quickly convinced him to join the band as well.
