Abstract
A molded rubber toy is formed with a hemispherical base, a shaft extending upwardly from the base, a spoke-like array of arms extending from the shaft and a bumper formed on the top end of the shaft The arms limit the tipping movement of the base, and the base is heavier than the combined weights of the shaft, arms and bumper so that the weight of the base rolls the toy back onto the center of its spherical base surface and into an upright position when the toy is upset from its upright at-rest position.
