About the title
The pop trolls are in shock — it turns out the world of music is much bigger than they thought. Raves, open-airs, classical concerts, and of course hip-hop battles — dizzying fun awaits them. But the unstoppable Queen Barb is planning to destroy it all... so that hard rock can rule the world unopposed! Poppy, Branch, and their new friends set out on an incredible journey: they must unite all the trolls and stop Barb.
