WEEBLE
Weeble
Weebles is a trademark for several lines of children's roly-poly toys originating in Hasbro's Playskool division on July 23, 1971. Tipping an egg-shaped Weeble causes a weight located at the bottom-center to be lifted off the ground. Once released, gravitational force brings the Weeble back into an upright position, though inertia causes the toy to wobble briefly before coming to a standstill. Weebles have been designed to have a variety of shapes, including some designed to look like people and like animals, among others.The above text is a snippet from Wikipedia: Weeble
