Abstract: A sounding toy constructed of a hollow, resilient body having a rigid, tubular valve member extending through a body wall and a toy balloon located inside the body receiving an inner end of the valve member by the neck of the balloon being trapped between two tubular portions of the valve member. Repeated, rapid, squeeze and release of the body everts and reciprocates the balloon through the valve out from and back into the body, inflating the balloon outside the body each time with a startlingly loud and sharp pop or crack.
