It's fun to practice walking with these classic push toys. The little helicopter twirls its rotor and makes a click-click sound as it spins, and the wheel creates happy sounds as it turns. Both toys are made from all-natural, safe materials that help improve balance and directional skills. Helicopter: 18" long x 4" wide x 19" high Walk 'n Roll: 4" wide x 7" deep x 22.5" high Expertly crafted of chemical-free, recycled kiln-dried rubber wood, and finished with nontoxic water-based paint. When helicopter is pushed, the rotor blades spin and create a clicking sound, providing an incentive to push. When the Walk 'n Roll wheel turns, the wooden ball inside hits the panels, creating sound. Ages 18 months and up.
