Punpun is the bird-like protagonist of Inio Asano's manga Oyasumi Punpun, and darker fan edits of the character have become a familiar sight in short-form meme videos, where a cute design is twisted into something unsettling. This jumpscare clip follows that same pattern, using a sudden loud sound to sell the transformation rather than telling a story of its own. Like a scream meme, it works because viewers already recognise the contrast between Punpun's innocent look and the horror-style payoff, so creators reuse it as a quick shock in edits, compilations and reaction clips.

A short, sudden Shadow Punpun jumpscare sound effect with a loud, startling hit, used in meme edits and reaction videos to shock viewers before a reveal.
The clip hits without warning: a sharp, loud burst that feels like a door slamming open in a horror scene, followed by a tense, distorted tail that makes the moment feel much bigger than its single second. It is built for surprise rather than atmosphere, so the shock lands instantly and then cuts off before the listener can settle. In a video, that sudden spike grabs attention, breaks a calm setup and turns an ordinary edit into a startling punchline, especially when the image switches at exactly the same moment to a dark or unsettling version of Punpun.
