Travel back in time with D-Rex, a walking, roaring, chuckling prehistoric pet. The rubbery robotic reptile with over-sized feet and tiny arms moves around like a real T-Rex. D-Rex responds to touch by moving his eyes, nose, mouth and tail. Or you can give him a command using the plastic bone-shaped controller. With five different modes (attack, seek, question, prank and guard), D-Rex is hours of fun.
