Your little one will discover a symphony in motion with this sun and moon musical mobile. The crescent moons are made in a soft white curly boucle and the suns are a creamy yellow velour. Their smiling faces are expertly embroidered. This musical mobile plays nursery songs for 20 minutes, has an on/off switch, and volume control. It plays Twinkle Twinkle Little Star, Brahms Lullaby and Rock-a-Bye-Baby and turns off automatically after 20 minutes to help preserve the battery life. Requires 3 AAA batteries, not included.
