Deltarune is a role-playing game created by Toby Fox, first released in 2018 as a follow-up to the world of Undertale. Its distinctive chiptune music and retro sound effects have made its audio popular for reuse, with fans clipping short moments for edits, streams and memes. A brief falling sound like this one is easy to recognise out of context, because the descending tone immediately signals a drop or a mistake. That instant readability is why it keeps appearing in short-form videos, reaction clips and gaming compilations.
