Jem - Season 3 - Eps 34: The Day the Music Died
After Jem disappears with Riot to Mexico all hell breaks loose when Pizzazz and the other Misfits take over Starlight Music and Starlight Foundation. The Holograms and the remaining members of The Stingers, Rapture & Minx, join the Misfits to make a mega-group. Rio, the Holograms and the Stingers decide to try and track down their friends, who by now, after a boating accident, are stuck on a deserted island. They are found and go back to the states. When Jerrica returns, Pizzazz (who is at her wits end - the Starlight girls have totally run riot) hands over Starlight Music and Starlight House back to her. Alls right with the world after this and everything goes back to normal.
