They see you trolling, but nobody’s hating. That’s because there’s so much that rocks about this build-it-yourself LEGO playset – especially for young Trolls fans. Kids will get to put on a wild Volcano Rock City concert complete with all sorts of crazy theatrics, like movable felt wings on each side of the stage, spinning platforms for epic rock battles between Poppy and Barb, and enough exclusive costume and hair accessories to put Mariah to shame. What a sweet, sweet fantasy that is.
