This is the classic Intex ride-on shark. It has a pair of sturdy grab handles to hold on to. Each front fin is a separate chamber to give the shark extra riding stability. They are each inflated with their own number 2 size valve while the rest of the body and fins are inflated with a third number 2 size valve.
