The clip comes from Sonic.EXE: Spirits of Hell: Round Two, a fan-made horror game built on the Sonic.EXE creepypasta that has haunted the internet since the original story appeared in 2011. Like its sibling Sally.EXE: The Whisper of Souls, the game turns cheerful Sonic stages into survival horror, and its jumpscare stings have become shorthand for retro-game dread. Lifted onto soundboards by horror fans, the scream now appears in creepypasta readings, Game Over edits and reaction videos, keeping the blue blur's evil twin alive in meme culture.
