Dogsong comes from Undertale, the independent role-playing game created and scored by Toby Fox and released in 2015. The track is part of the game's well-known soundtrack, which fans have shared, remixed and clipped for years across video platforms and soundboards. Its short, catchy melody made it easy to lift out of context, and creators now use the brief excerpt as a shorthand for playful chaos in memes, edits and streams. That lasting connection to Undertale keeps it recognisable even to viewers who have never played the game.
