For nearly 25 years, Nintendo sound designer and composer Kazumi Totaka has been sneaking a song — a 19-note melody commonly known as "Totaka's Song" — into the company's video games. From Mario Paint to Yoshi's New Island, the simple tune has appeared in multiple Nintendo games, and usually requires some digging to find.
Now the tune has been discovered in a new Nintendo game: Mario Kart 8 for Wii U.
According to a video from Somewhat Awesome Games, "Totaka's Song" is secretly being sung by the game's spectator Yoshis, the ones who hang out trackside on courses like Donut Plains 3, Yoshi Circuit and Sweet Sweet Canyon. Pull up to one of those Yoshis and you might just hear him hum the tune. That's a fitting format for the musical Easter egg, as Totaka serves as the voice of Yoshi in a long list of Nintendo games.
The first reported appearance of "Totaka's Song" comes from Game Boy game X, and you can hear multiple instances of Totaka's secret tune in this compilation video.
