Laughing Robot No.36021 by Yonezawa - A Battery Operated Japan Robot with mystery bump and go action. Push the button on his head and he laughs or hear a space sound. Robot stands 10 inches tall and operates via 2 C cell batteries. When switch at rear is turned on, robot moves in bump-and-go mystery action fashion. When button on head is depressed, robot will either laugh or make siren sounds. If the head button is depressed while it is moving, the robot stops and "talks". It then continues to bump-and-go.
The robot comes in a light blue color, black color and a chrome color variation. All perform in exactly the same way as the light blue color variation. There is also blue chrome color whose name is in the Japanese language on the box which translates into "New Patrol Robot". Instead of laughing, it speaks in Japanese.
