The Werehog is the nighttime transformation Sonic takes in Sonic Unleashed, the 2008 Sega game where a curse splits his speedster form from a stronger, stretch-armed beast form. Clips of his pained yell were later ripped from gameplay and cutscenes and shared as a standalone reaction sound. Its short length and recognisable Sonic voice made it easy to drop into edits, memes and fan videos, where it now signals pain, shock or a forced transformation without needing any context from the original game.
