This sound is widely known from The Legend of Zelda series, where a short jingle signals that the player has uncovered a secret. The effect became strongly associated with hidden rooms, discoveries, and puzzle rewards in Nintendo-era game culture. Over time, it spread into YouTube edits, livestreams, and meme clips as a quick audio shortcut for “you found it.” It still gets used because the cue is so short, clear, and instantly readable even to viewers who only vaguely recognize the reference.
