Abstract
A rollable toy having a body with axles having rollable members thereon. Each axle has a stepped, resilient, headed male portion and a female portion with which it mates, each portion having an outer socket for receiving a boss on a spherical wheel member. The wheels may be fixedly or removably mounted to the axles and may have loose contents creating a sound when rolled. A face member may be removably mounted on the body.
