Just like the original 7" windup made in the 1950's in Japan. Wind him up and watch the sparks fly! Sparks shoot out of the hole in his chest as he walks. On/off switch on his back pack control the action. Great classic boxy design from which many other robots were born! The walking mechanism on Sparkling Mike is very unique and referred to as the "pizza cutter mechanism", whereby each foot has a wheel attached to a shaft that moves inside the foot enabling Mike to walk. An ingenious design which causes Mike to skate rather than walk at times! For adult collectors only. For decoration only.
