Hello. I am a thoughtful concrete mixer. I speak cheerful phrases, play child-friendly melodies and songs, and make funny sounds. There is a bright button to press. An additional button makes the drum rotate and triggers corresponding sounds. I respond to the movement of the wheels. I react to the magical sensors of the Tut Tut Baby Flitzer playsets. There are 3 sung songs and 6 children's melodies. The child-safe battery compartment and automatic shut-off ensure safety. Demo batteries are included.
