Deltarune is Toby Fox's episodic role-playing game, and Chapter 3 takes place largely in the TV World ruled by Tenna. Short interface and environmental effects from the chapter are frequently clipped by fans for soundboards because they are instantly recognisable to players despite lasting only a second. This sonar cue spread through gaming edits and meme posts where a brief ping communicates searching or discovery faster than dialogue. Its connection to a popular recent chapter keeps it in circulation among Deltarune fans sharing favourite moments.
