Gaster is the secret, largely unseen figure tied to Undertale, the 2015 role-playing game by Toby Fox, and his presence has become a shorthand for hidden lore and unsettling discoveries among fans. Because he is rarely shown directly, even a tiny associated sound carries a lot of weight in fan edits. Numbered clips like this one circulate on soundboards, where creators grab the shortest, most recognisable fragments for memes, theories and horror-style videos. Its staying power comes from that mystery rather than any single famous scene.

A short, glitchy Gaster sound effect from Undertale, used for sudden reveals, jump scares and creepy moments in memes, edits and fan videos.
This clip is a single, split-second Gaster blip, barely longer than a blink, with a hollow, slightly distorted electronic tone that sounds like a corrupted line of game dialogue. It arrives without warning and ends before the listener can settle into it, which is exactly why it feels so unsettling. In a video, that tiny burst reads as a glitch in the scene, a hidden presence stepping into frame, or a character noticing something they should not have seen. It does not explain itself, so viewers fill the silence after it with dread, curiosity, or a joke landing at just the wrong moment.
