Boomer will react depending on the mood he is in. he can open and close his jaws, roar and change the color of his eyes in three different colors; blue when he is happy, purple when in training and red when mad. The mood is activated through interaction, like patting his nose and pulling his tail. This Dino toy uses a self balancing technology similar to the Segway. With just two wheels, the Dino can move in all directions and turn without falling. A wireless remote is also included to get complete control.
