Can anyone rescue him before the shark finishes its snack? The munching shark costume is a funny adult shark attack costume. It comes with a gray polyfoam shark suit that features eyes, fins and an open bottom for easy movement. The shark's mouth is open for your upper body and gives the appearance of an attack. The mouth is lined with teeth and measures 17" wide by 14" tall. The suit is secured in place with clear straps and has a slit for the covered arm. The fins and nose of the shark should be stuffed for the best appearance. Play the "Jaws" theme song as you approach!
