The secret jingle comes from Nintendo's The Legend of Zelda series, where a musical cue has signalled that the player has discovered something hidden, such as a concealed room, passage or item. Versions of the cue have appeared across many Zelda games since the early entries in the series, helping it become one of gaming's most familiar reward sounds. Online, creators lifted the clip for reaction videos, gameplay edits and memes, using it as shorthand for a discovery, a plot twist or a hidden joke.
