The Amazing Wave of Light Animatronic Dolphin is a work of art that combines lights, sound and movement. The visual experience is hypnotic, creating a relaxing tranquil environment for any room in your home or office. You can choose from three modes: 1) Watch it move in a well-lit room with the Sound & Movement Mode; 2) Bring it into the bedroom shut the light off and watch the Movement, Sound and Light Mode take over - completely relaxing you; 3) Simply use it in the Movement Only Mode (with no sound or light) and be mesmerized by the slow graceful movement of the Dolphin. The Amazing Wave of Light Animatronic™ Dolphin has a built-in Sleep Timer Mode; with the push of a button it can be set to turn off in a 30 minutes to one hour. Cons: One user reported that the dolphin's nose got stuck and wouldn't go back down.
