Our green remote-controlled RC Walking T-Rex LED Dinosaur is mammoth fun at a prehistoric price. At 18"L and 12"T, this walking, roaring dinosaur toy for boys and girls moves, makes sounds, and lights up! Powered by a total of 5 included, installed & replaceable AA batteries in the dinosaur, a simple toggle of the on/off switch along with the use of the remote control has the primitive T-Rex predator on the move. Its lifelike jaws open to roar and its eyes flash green while its tongue blinks red & blue. With each step forward, the spine down its backlights up and flashes red and blue as it ferociously warns of an imminent attack. A great gift for ages 3+.
