Kappa Mikey Season 1 Episode 16 Battle of the Bands

The cast stumbles upon a bunch of instruments in the soundstage's audio booth and decides to start a band. They stink, but Ozu mistakes a ringtone on Mikey's cell phone for the band's music and changes the LilyMu show to take advantage of their musical abilities. They play along with the ruse for a while, but when the LilyMu Band gets called out by a rival group of girl rockers, a Battle of the Bands ensues.
