Furms are small creatures encountered in Hollow Knight Silksong, the sequel to Hollow Knight from Team Cherry. Their singing became a small standout moment for players exploring the world, because the gentle chant contrasts with the danger and silence around them. Clips of the Furms performing were shared by fans in gameplay videos and edits, turning the brief in game moment into a recognisable sound outside the game. It remains popular with Hollow Knight fans who use it to mark cute, peaceful or unexpectedly funny scenes in their own content.
