Undertale bone zone

Short bone rattling sound effect from Undertale, tied to Sans and Papyrus skeleton attacks. Gamers use it for skeleton jokes, spooky edits and meme hits.

This is a brief, sharp bone effect lasting less than a second, with a dry clack and rattle that sounds like cartoon skeleton bones snapping into place. In Undertale it fits the skeleton brothers and their bone attacks, so hearing it instantly signals something bony, goofy and slightly threatening at once. The hit is clean and percussive, with no music or voice underneath, which makes the joke land immediately. It works as a punctuation mark rather than a scene, turning a reveal, a fall or a skeleton reference into a quick visual gag.
