Deltarune is Toby Fox's episodic role playing game, and Chapter 3, released in 2025, is set inside a TV world ruled by the flamboyant host Tenna. His segments parody classic game shows, complete with a live studio crowd that cheers, laughs and gasps on cue. Players clipped this particular ooh because it captures that theatrical atmosphere in under four seconds. Shared on soundboards and in fan edits, it has become a reusable shorthand for collective surprise far beyond the game itself, especially in gaming videos and memes.
