The Illumivor Mecha-Shark is a glowing radio-controlled predator with animated chomping teeth, a smooth moving tail and ominous sound effects. Menacing in the light, these mechanized carnivores really come to life in the DARK, when they appear to be swiftly swimming across the the floor. Illumivor Sharks are huge, measuring 18 inches from nose to tail. Control the attack with a cool Shark Fin Controller (included).
