Abstract
Pneumatic action toy creatures each have a body with a hollow resilient compressible portion. An opening in the compressible portion receives an elongated piston with a cross section substantially conforming to the opening to provide for pneumatic reciprocation of the piston. At least one set of opposed members is mounted for pivotal movement with respect to each other in a direction, and about an axis, generally transverse to the elongated dimension of the piston. Either by an enlargement on one end of the piston, or through interaction with the opposed members, the throw of the piston is limited to retain the one end within the compressible portion. Reciprocation of the piston upon compression and release of the resilient body portion actuates pivotal movement of the opposed members through mechanical engagement.
