When the music starts pounding at Techno Reef, all the Techno Trolls move to the beat. The DreamWorks Trolls World Tour Techno Reef Bobble features 2 different figures inspired by the movie Trolls World Tour, Trollex, the leader of the mermaid trolls Techno Reef, and a Mermaid Kid. The Mermaid Kid figure has a bobble head, so kids can pretend he's rocking to the beat of the techno music. The set also includes a base inspired by Techno Reef. Put the Mermaid Kid on the base and touch the heart-shaped piece, and the base wobbles to make his head bobble. Kids can imagine they're visiting Techno Reef on an epic adventure to save all of music with this toy.
