Attention construction site! Enjoy sorting and transporting with the colorful tipping truck that invites learning, playing, and moving. The contents include numbers, colors, and tools. The movable tailgate with a lever for tipping the load wobbles while driving. It features three colored tool buttons and a magical opening that recognizes the balls. The electronic wheel triggers sounds, phrases, and melodies, including two sung songs and ten children's songs (lyrics in the manual) with volume control. The child-safe battery compartment ensures safety, and there is an automatic shut-off function. Two AAA demo batteries are included.
