Piggy began as a Roblox horror game built around infected animal characters, and Sheepy is one of its sheep characters, shown here in her uninfected form before the infection storyline. Piggy Rebooted keeps that cast and chase format alive for fans creating their own chapters and clips. Short scare sounds like this spread through Roblox edits alongside the ROBLOX oof and the FNAF Jumpscare Scream, because a familiar character plus a sudden scream works instantly, even outside the original game, in compilations and fan made horror shorts.
