Luigi is Mario's younger brother and a long-running Nintendo character who has appeared across the Mario games for decades, from platformers to party and sports titles. Short game sounds like his footsteps have become popular on soundboards and in short-form video because they are instantly recognisable, even without any visuals. Creators reuse them to add a playful Mario flavour to edits, memes and streams, and often pair them with the Mario Jump sound to recreate a familiar run-and-jump sequence.
