Everwing is a vertical scrolling shooter released on Facebook Messenger's Instant Games platform in 2016, where players fly fairy guardians with dragon companions. Dragons are obtained by hatching eggs, with common eggs being the most basic tier. The end-of-hatch sound signals that the incubation is complete and the new creature is ready to collect. Clips of Everwing's interface sounds circulated among mobile and browser game fans, and this short cue became useful beyond the game as a generic fantasy hatching and unlocking effect for videos and edits.
