Sheepy is a sheep character from Piggy, the Roblox horror game, and the infected version appears in Piggy: Rebooted, a fan-made reimagining of the series that recreates its chases and jumpscares. Clips of the scare were shared in gameplay videos and reuploaded to soundboards, where Roblox horror fans kept using them for edits and reaction moments. Like the Roblox oof and the FNAF jumpscare scream, it survives because it instantly signals danger and a failed escape, giving creators a short, recognisable shock they can drop into almost any scary sequence.
