Deltarune is an episodic role-playing game created by Toby Fox, first released in 2018 as a companion story to Undertale. Its battle system uses short, distinct audio cues for attacks, defence and recovery, and the heal chime marks spells and items that restore HP. As clips and memes from the game spread on video platforms, players began lifting familiar battle sounds for edits outside the game. The heal effect stayed popular because it is instantly recognisable to fans yet clear to newcomers, making any quick recovery feel like a game mechanic.
