This is a short, bright Nintendo tune by Kazumi Totaka, lasting about fourteen seconds, built around a simple, bouncy melodic line that feels instantly familiar. It gives a playful, conspiratorial lift, like sharing a wink with someone in on the joke. Totaka hid versions of it as an easter egg across several Nintendo games, so hearing it feels like stumbling on a secret meant to be found.
