Xa, as this thermoplastic rubber skin is called, has unique features that inspire creativity and active outdoor fun. Push a balloon through an opening in the skin, blow up the balloon, tie off the stem and tuck the end under the skin, and you have an altogether new toy. Filling the balloon with water creates another. Stuffing Xa with a sponge, and wetting the sponge is yet another. This is exploratory play at its best. Phthalate and latex-free.
