Luigi's Mansion 3, released for Nintendo Switch in 2019, brought back Boo, the shy white ghost from the Mario series who hides its face and flees when looked at directly. The game's playful take on haunted houses made Boo's panicked voice a favourite among players, and short clips of the scream began circulating on soundboards and in gaming edits. It remains popular because it works as a light-hearted jumpscare scream, scary enough to startle, but cartoonish enough to stay funny in memes and streams.
