3D wooden puzzle that you build into a robotic dinosaur! This is not your average puzzle - he walks, roars, and turns. The Dino's are clap controlled: one clap walk & roar, two claps to turn right, and three claps to turn left. Incredibly fun to build with detailed instructions for every step of the way. Be prepared to spend some time on this as they are complex designs that will intrigue and challenge your young engineer. Precision cut wooden sheets require no glue or tools to assemble. This product is also environmentally friendly with the wood sourced from a protected forest where we replace two trees for every one utilized.
