Hello. I am a responsible police car. I speak cheerful phrases and make funny sounds. An additional button triggers great effects. I play melodies and songs. There is a glowing button to press. I respond to the movement of the wheels and the magical sensors of the Tut Tut Baby Flitzer world playsets (sold separately). I have 3 sung songs and 6 children's melodies. The child-safe battery compartment and automatic shut-off ensure safety. Demo batteries are included.
