Phoebe the penguin is a sleep aid with soothing light and sounds. You could attach Phoebe to your crib using the velcro strap. Its removable module could play 7 pre-set sounds such as shushing (shh sshhh a doctor's proven technique), heartbeat, white noise, lounge music and 3 types of lullabies. You can record your own voice or favorite song for 30 seconds using the voice recording option. Select your preferred volume from low to high. In addition, the module shows a relaxing soft orange nightlight., After 20 minutes the light and sound switch off automatically. The optional cry sensor could reactivate the last used settings (only pre-set melodies). Once the module is removed you could wash the plush by hand and dry it in the air. Powered by 3x AAA batteries (not included).
