ZOOB 250 Construction Set from Infinitoy is a building set with a difference - pieces move after kids put them together. Kids can play with their ZOOB creations instead of just looking at them. Pieces snap, click, and pop together to form joints that rotate, limbs that extend, axles that spin and lots more. ZOOB encourages your child to learn, explore, and create using the most important tool of all...their imaginations. ZOOB 250 building toy set includes 250 ZOOB pieces in a re-sealable storage bin. Complete with full-color instructions for 23 creations. Unlimited Creative Building!
