We believe in the buddy system, which is why we created Pool Petz: so your little ones will never set out on the open water of a pool alone. They come in a ton of fun animal shapes and each is covered in mesh fabric that dries quickly. Instead of boring, old hot air, we filled them with our patented beans for plenty of buoyancy - and those same beans make the Pool Petz lightweight and easy for small hands to pick up and carry.
