Papyrus is one of the skeleton brothers in Undertale, the role-playing game released in 2015, where he dreams of joining the Royal Guard and constantly announces himself with a loud, boastful laugh. Fans began clipping that laugh for edits and reaction videos, and it later travelled through TikTok and YouTube as shorthand for overconfident reveals and absurd entrances. The 'becomes real' version plays on that joke, imagining the cartoon skeleton stepping into the real world, which is why creators still use it for surprise appearances.

Papyrus's loud NYEH HEH HEH laugh from Undertale, used in memes when the skeleton becomes real for surprise reveals and goofy villain moments.
This ten-second clip captures Papyrus bursting into his signature loud, wheezy laugh, a high-pitched NYEH HEH HEH that rises and repeats until it feels almost unstoppable. The voice is theatrical and overconfident, exactly the way the tall skeleton from Undertale tries to sound cool while failing spectacularly, and the sudden energy makes any reveal feel bigger and sillier. Hearing it instantly signals that something absurd is about to happen, whether a character appears out of nowhere, a plan backfires, or a joke lands with far more confidence than it deserves.
