The chest jingle comes from Nintendo's The Legend of Zelda series, first released in 1986, where opening large chests signalled finding a key item, weapon or piece of equipment. Composers for the series turned the moment into a recurring musical cue, kept and rearranged across games like Ocarina of Time and Breath of the Wild. Shared in gaming videos, streams and memes, the fanfare became shorthand online for finding something valuable, long after players first heard it on Nintendo consoles.
