Mike appears in Deltarune Chapter 3, the third chapter of Toby Fox's follow-up to Undertale, set inside a television-themed world. His laugh quickly became a favourite clip among fans after the chapter's release, shared in short edits and soundboards as shorthand for a mischievous showman. Because the laugh is short, distinctive and easy to recognise without dialogue, creators keep reusing it for reaction videos, gaming moments and memes, long after the initial wave of Chapter 3 playthroughs.
