Abstract
Sketelay animals toys capable of rolling and bouncing comprise polyhedra or other skeletal structures which can be inscribed on an imaginary spherical or ellipsoidal surface, torii and linear members which form a cylinder with circular cross-section, or elliptical and linear members which form a cylinder with elliptical cross-section. The skeletal animal toy is formed of an elastomeric material, which is preferably natural rubber, synthetic natural rubber, or a blend of natural rubber or synthetic natural rubber and one of a plurality of blending polymers including butadine rubber, styrene-butadiene rubber, nitrile rubber and ethylene-propylene-diene-monomer rubber.
