Abstract: An activity toy with a body including a hollow cylindrical portions supported on a base and having pivotally mounted arms has a hollow upper member including a skull with extrusion openings. The bottom of the upper member has a loading opening for a plastic amorphous solid substance. Attachable about and spaced from the skull is a clear plastic mask formed of separable halves clamped together at the bottom by the engagement of hooks and tabs and at the top by a detachable hairpiece. Near the bottom, the mask is maintained in a relatively tight relation to a flange on the hollow upper member. The upper member with the mask attached is secured to the body by a bayonet lock. Within the body is a piston with diametrically opposed gear racks that are engaged by gear segments on arms pivotally mounted to the body.
