Crackbot ® / Sucharaka Bot ® manufactured by Tomy ®
Crackbot and Sucharaka Bot has a sound sensor located on the top of his spiral tail. You could clap your hands and he would stop, perform a number of movements with his head, then carry on. He moves around in a circle and while doing this his body rotates and his arms swing violently, as if he had loose joints on his body. When a sound was heard, he stops, raises his head up and down while making noises and then moves on.
Requires 3 C size batteries
