Sky: Children of the Light, often shortened to Sky COTL, is a social adventure game by thatgamecompany where players fly through open skies and oceans and meet gentle creatures along the way. Short creature sounds from the game are commonly saved and shared by fans as soundboard clips, and numbered versions such as this one usually mark a second take or a slightly different recording of the same call. It remains useful because Sky players recognise the calm, aquatic tone instantly, even outside the game itself.
