Although Pierceton does offer these pieces all individually, if you are considering adding all of them to your play space, you may as well save yourself some money and order the Set of Four Rubber Animals. The set includes a crocodile, dolphin, frog and turtle, and can accommodate several children comfortably. They all boast one piece construction so you do not have to be concerned with rough seams causing scratches, cuts or irritation on delicate skin. These pieces of playground equipment inspire creative fun that children will want to go indulge in. You have the option of six different colors, so you can order them all to match or each one as a different color. Governmental security groups have authorized this Set of Four Rubber Animals, and they meet CPSC guidelines.
