The sound comes from Nintendo's The Legend of Zelda series, where opening a treasure chest has long been accompanied by a short, celebratory jingle that tells the player an item has been found. The cue has been kept and adapted across many Zelda games, which helped it become one of gaming's most recognisable reward sounds. Online, it spread through gameplay clips, streams and edits, where creators reuse it far beyond Zelda itself. It endures because it instantly signals success, discovery and a small prize, even to viewers who have never played the games.
