Gamma radiation can get expensive and dangerous so try using this Child Avengers Hulk Light-Up Costume to turn your kid into the Incredible Hulk! It includes a jumpsuit and a mask. A branched vein is painted on each side of the chest and outlined with tiny green LEDs, which light up when the "On" switch on its battery pack, located in a small pocket on the inside of the suit, is pushed; it uses two hearing-aid-type batteries. Instructions are included. Complete this costume with a pair of Hulk hands and let your kid go smashing!
