Dogsong is a track by Toby Fox from the 2015 game Undertale. In the game, it is strongly associated with the annoying dog character and the series' offbeat sense of humor. The tune became a favorite in fan videos, memes and gameplay edits because its looping, playful feel instantly signals mischief and absurdity. It is still widely used by Undertale fans and creators making dog jokes, retro game edits or short clips that need a recognizable burst of quirky game music.
