Sprunki is a fan-made, Incredibox-style music game in which players mix sounds from colourful characters to create tracks, and it spread widely through gameplay videos and short-form clips online. Retake versions revisit that formula with new character designs and darker themes, and Mr Tree is one of the game's tree-like characters. In horror versions, familiar characters are reimagined with distorted sounds and unsettling visuals, which is why clips like this one are shared for spooky edits, reaction videos and Halloween-themed content.
