Hidden in a remote place surrounded by high mountains, there lies a secret valley. There is an entrance, but you could pass by it a hundred times and still not see it... Spring has arrived, and our friends of the hidden valley are celebrating in musical style! Mister Cold and his band of friends have played and danced their way to the Garden of Fairies and all the way to the Ogre's house. When Mister Cold suddenly disappears, and the gang find themselves in a spooky part of the woods, they fear the worst... until a new instrument joins their tune!
