This is the plush teddy with a built-in MP3 player and internal speaker for playing soothing lullabies at naptime or a cheerful soundtrack during play. It comes pre-loaded with 90 minutes of calming nature sounds and classic children’s songs such as The Wheels On The Bus, Brahms Lullaby, and Twinkle Twinkle Little Star. Parents can add six hours of their own music or voice recordings (for example, a favorite bedtime story) to customize its three playlists for different times of day or different children.
