Abstract
A mechanical toy capable of turning itself upside down has a body shell shaped to include a curved surface such that when it is self inverted it rolls upon the curved surface back to its upright position. The body includes supporting members, preferably wheels, on which the body normally will rest. An inverting member is operatively attached to a motor and cyclically raises one end of the body allowing the body to pivot about a pivot surface which imparts a rolling motion to the body. The body rolls from the pivoting surface about its curved surface to its upright position and then preferably rolls on its wheels until it once again inverts itself.
