Frostiggy comes from Piggy: The Result Of Isolation, listed here in its Reimagined form, a fan made Piggy horror experience built around isolated, winter themed encounters. The jumpscare sound is attached to the character's attack moment, when the quiet exploration breaks and the threat appears at close range. Clips of that moment circulated among Piggy players online, and the audio was separated for soundboards so creators could reuse the scare outside the game. It remains popular for short horror edits because the hit is instant and recognisable to fans.
