Cute colorful dinosaurs underneath a canopy of leaves gently soothe your baby to sleep while rotating around and playing Brahms Lullaby, Twinkle, Twinkle Little Star, and Rock-a-Bye-Baby. The dinosaurs are made in soft velour, have embroidered spots and laser cut felt spikes. This mobile plays music for 20 minutes, has an on/off switch and volume control. The mobile arm is covered in white velour and the music box sticker features a baby dino sitting in his eggshell. Requires 3 AAA batteries, not included.
