Swimline`s Blue Dolphin Stable Ride-On is almost as fun as swimming with real dolphins. The inflatable pool toy for kids is made of heavy-duty materials that will withstand years of enjoyment. The dolphin is made with a flat design for greater stability. Dolphin toys for kids allow your children to exercise their imagination while they play in the pool. Swimming pool riding toys are recommended for kids age 4 and up. Non-slip hand grips are included on either side of the head.
