Learning is tons of fun with the Drop & Go Dump Truck™. Drop a colorful rock into the top of this cute toy dump truck, and watch it tumble into the bucket. Your little one will learn numbers as the interactive truck counts each rock. Once the rocks are in the bucket, push or pull the truck along to see the rocks rumble inside. Then, lift the hinged bucket to unload the rocks and start again while developing motor skills. The dump truck also includes 3 colorful buttons that play melodies, phrases and teach tools and colors. Batteries included for demo purposes only. New batteries recommended for regular use.
