The pneumatically-operated robotic toy includes an internal bellows or air pump which forces pressurized air to flow from the internal air pump or bellows through passageways into hollow arms of the robot. Inasmuch as the arms of the robot include bellows, this flow of air causes the arms to move from an open to a closed position, or vice versa. Air pressure holding joints are provided to permit several degrees of freedom of movement. Alternatively, the internal bellows may be positioned in the head of the robot, and movement of the head will cause the arms to move up and down. A flexible rotatable suction cup base may be provided. A second internal bellows may be provided, either in the torso or in the head, for activation of the suction cup base of the robotic toy.
