Undertale is a 2015 indie role-playing game created by Toby Fox, where dialogue appears letter by letter in text boxes accompanied by a distinctive typing blip that changes with each character voice. Frisk is the human child the player controls throughout the underground adventure. Clips of the typing effect spread through fan games, animations and soundboards because it captures the game's lo-fi charm in less than two seconds. It remains popular for recreating RPG conversations and for signalling typed thoughts in short videos.
