Car Carrier from Melissa & Doug. This is a simple, classic toy that's irresistible for kids who love everything on wheels: the carrier has two tiers, and the top level swings down to load up. Your child will have a ball loading the four included cars on and off, and "driving" his truck around. The Melissa & Doug Car Carrier's trailer can be hooked and unhooked from the cab – it's simple enough for small children to do on their own, too. The included cars are compatible with wooden train tracks, adding to the Car Carrier set's play value.
