Yarnaby is a lion-like toy monster from Poppy Playtime, the indie horror series built around a haunted toy factory, and this clip comes from the Safe Haven chapter where players encounter him. Short jumpscare audio like this is routinely clipped by players, uploaded to soundboards, and reused in gameplay videos, edits, and reaction content long after release. It remains popular because it is instantly recognisable to fans of the series and, similar to the FNAF jumpscare scream, delivers a complete scare in under a second without needing any context.
