Undertale is a 2015 indie role-playing game developed by Toby Fox, known for its pixel art, branching choices and memorable menu sounds. The create sound comes from the opening naming sequence, where players enter a name for the fallen human before the story begins. As clips of gameplay and fan projects spread on YouTube and soundboards, this short confirm tone became shorthand for starting something in a game. Its simple retro design still fits modern edits, streams and memes built around character creators and RPG menus today for many players.
