It's not wishful thinking -- there really are bath toys that move without batteries! Meet the floating Sea Spinner wind up bath toy. This adorable toy shark is ready to float and play, and best of all, it requires no batteries to move and spin its way through the tub. Little ones can easily wind up the bottom fin to make it go, go, go. It's designed to be water-tight, so you don't have to worry about mold and mildew, either. Equipped with a floatie and a smile.
