(Crappy cover pic is bound to change) Poppy's reign as Queen is put to the test when her home faces a new threat in the form of Barb, Queen of the Rock Trolls. The new discovery soon leads Poppy and her friends to find that there are other kinds of trolls in the world, each defined by a string that represents their type of music. When Barb plans to take the strings and destroy all types of music, the clock is against Poppy and the Gang to unite the trolls kingdoms and get them working together to help defeat her. (Like the other fics of the same title, this is not official, just what I think will happen based on the trailer and some headcanons)
