Devsisters is a South Korean game company best known for Cookie Run, the long-running runner and puzzle RPG series starring cookie characters. Its short logo jingle has become part of the opening ritual for millions of mobile players, heard every time the games launch. As Cookie Run clips, fan animations and edits spread on video platforms, the sting was lifted on its own and shared as a recognizable gaming sound, used by fans who want an instant reference to the series without showing any gameplay.
