Online soundboard listings identify this clip as the Denny Scream, a recording dated to 2013 that became associated with a 2015 piece titled Midnight Corn. From there, editors began reusing the same long wail for Denny, and sometimes for Silver and Luigi, turning a single character scream into a reusable reaction for panic and failure. Because the voice is so distinctive and the take is short enough to drop into a meme, a short video or a soundboard button, it has kept circulating among creators who want an instantly recognisable burst of cartoon distress.
