i-CAT even changes his mood to suit your music. Simply play something new and i-CAT entertains you with expressive movements and flashing LED lights that change color. Touch the lights on his face to add "scratch" and "drum" effects to the music. He even features a "Beat Builder" Memory Game, where you have to repeat i-CAT's lights and sound sequences. Requires 2 "AA" batteries, not included. Measures 3.25" x 3.25" x 3".
