The Werehog comes from Sonic Unleashed, released in 2008, where Sonic transforms at night into a slower, brawler form with stretchy arms. Its nighttime stages use a separate battle theme that starts whenever enemies appear. Fans later isolated that music and Sonic's transformation scream, and this mixed version credited to Rinerous spread on soundboards as a short meme clip. It stays popular with Sonic editors because the pairing instantly signals the Werehog without needing any footage from the game itself.
