Halloween is right around the corner and you still don't have a costume? What, does it need to knock you upside the head or something? Put on this Boy's Hammerhead Shark Costume for trick-or-treating and bring out the marine biologist in all your friends. This silly get-up is made of a plush polyester foam that will keep you nice and cozy as you swim around those deep sea trenches. The top is molded with the hammerhead shark's famous nose, two eyes staring out from under it. The long sleeves are closed off with seamless mittens to make it look like you have flippers. The sharp-toothed mouth is actually a gap for your face, making it look like you were its most recent meal! A tall fin and long tail are sewn into the back of the Boy's Hammerhead Shark Costume. Slip into in and tune into Shark Week!
