Six colours to match! When your switch or the edge of this device is touched, the dice spins and reveals one colour. The child then automatically scans and selects the matching colour on the caterpillar’s body. When the child matches all the colours, all the lights gently twinkle and a soothing tone is played. Original game pieces included. Size: 9½" x 7" x 3¾"H. Requires 4 AA Batteries.
