The secret jingle comes from The Legend of Zelda series, where it has signalled a hidden discovery since the original Nintendo game in 1986. As later Zelda titles reused the familiar tune, players began to associate it with solving a puzzle or opening a concealed passage. Clips of the sound then spread through gameplay videos, streams and short-form edits, where creators borrowed it as shorthand for any unexpected find. It endures because the melody is instantly recognisable, even to people who have never played the games.
