The Car Carrier from Green Toys encourages imaginative play with its smart & simple design, moving parts, and no batteries required! Kids can attach the trailer to the truck, extend the two rear ramps, and load up all three included cars before they hit the road to adventure with this super-cool play set. It doesn't feature any metal axels or small parts, so it's great for both indoor and outdoor play. Finally, it's made from 100% recycled plastic, so it's totally green, too!
