Undertale is a role-playing game released in 2015 and created by Toby Fox, where gold is earned by winning battles or sparing monsters. The bright sound that accompanies a gold reward became familiar to players through repeated play, and clips of battles and playthroughs soon carried it onto YouTube, TikTok and soundboard sites. Creators kept using it outside the game because the chime is short, cheerful and instantly linked to earning something. It now works as a quick audio shorthand for a reward, even for viewers who have never played Undertale.
