The globe has a knob to turn the light and sound on and off; and also to increase or decrease the volume. The settings on the globe are touch activated, not real buttons. They include: light, direction/speed of the mobile spinning, song, or different sounds. Each feature can be used together, independently, or pick and choose between light, sounds, and rotation of the mobile.
The bears in the globe light up and can be white, red, green, blue, or alternate between all the colors or turn the light off and just have music or spinning.
The different extra sounds the globe makes are a baby giggling/cooing or babbling, heartbeat on a sonogram, a stream with birds, a brook with frogs, or just birds.
This mobile has helped tremendously with sleep training our daughter.
