Journey to Shangri-La - S3.E22

The Holograms hear the story of Shangri-La, a magical city that no one can find and contains magical music. They decide to go in search of the city in order to learn the music and add it to their act. Naturally, the Misfits follow them to find out what they are up to. When Pizzazz and Roxy are poisoned by thorns in the snowy mountains, the others learn that only the magic music of Shangri-La can heal them. An old woman shows the Holograms how to reach the city, and the girls learn the music in time to heal Pizzazz and Roxy. The Misfits try to go to Shangri-La themselves, but the city vanishes.
