The crickets chirp is an old comedy trope for silence after a flop, long used in cartoons and sitcoms before games adopted it. This version comes from Deltarune, the episodic role-playing game by Toby Fox, in Chapter 3 and its TV World section hosted by Tenna. Fans clipped the moment and reused it outside the game as a reaction sound for dead chats, failed bits and uncomfortable pauses. Its link to Tenna's show format explains why it feels like a live studio audience refusing to respond.
