This is the autonomous robotic dinosaur that erupts in Cretaceous fury at the slightest provocation. The velociraptor's snout has an infrared sensor that allows it to detect movement or objects. Once it locks on to its "prey," the dinosaur charges forward with feral howls and dervish-like spins. Closing its jaws by hand tames it momentarily, but if held closed for too long, it will begin to whimper angrily; double-clicking its jaws returns it to a state of rage. Bearing tooth-filled jaws and twin-clawed forelimbs, its two hind legs are coiled wheels that operate like a predator's tendons, enabling it to move rapidly over carpet, tile, and other smooth surfaces. The dinosaur can also be operated by the infrared remote that spins both wheels simultaneously for instant charges at a foe. Requires four AA and three AAA batteries. Ages 5 and up. 15" L x 5 1/2" W x 5" H. (2 lbs.)
