Aqua Squisheez represents a totally new concept in squishy and grow products. Filled with a material that expands in water, Aqua Squisheez will "inflate" five time their original size in about 30-45 minutes after emerging in water. Once inflated they become super soft and squishy, and will not dry out or shrink. Lots of fun to watch grow, and even more fun to squish and play with! Five styles to choose from!
