This short voice clip, just under five seconds long, delivers the repeated warning 'PBBV is watching, PBBV is here' in a low, menacing voice. It feels tense and uneasy, like someone unseen has just noticed you and is closing in. It comes from Gorilla Tag ghost stories, where PBBV is a fan-made figure said to watch or follow players.
