Angry Birds Star Wars was released in 2012 as a crossover between Rovio's bird-flinging mobile game and the Star Wars universe, with pig characters taking on Imperial roles and Probe Droids appearing among the mechanical enemies players had to knock down. Short clips from mobile games like this later circulated on soundboards because creators wanted brief, recognisable game audio for edits rather than long music tracks. The Probe Droid defeat sound has survived that way, as a compact effect that instantly signals a small enemy being taken out in a playful, cartoon version of Star Wars.
