Mario Kart World includes a Totaka's Song Easter egg. Discovered by one astute fan, this easy-to-miss detail appears to be within reach shortly after launching Mario Kart World for the first time.

Totaka's Song is named after Kazumi Totaka, a legendary Japanese video game composer who collaborated with Nintendo on dozens of titles since the early '90s. Apart from scoring games and handling sound direction, he's also known as the long-time voice of Yoshi. Totaka's Song has over three decades' worth of history, with its first appearance dating back to X, a 1992 Game Boy-exclusive space combat sim developed by Argonaut Games and Nintendo Research & Development 1. The melody has appeared in over 20 other games since then.

Mario Kart World is now confirmed to have joined the Totaka's Song roster, with the iconic 19-note melody recently being found in the flagship game from the Switch 2 launch lineup. The discovery was made by Reddit user CharizardTelephone, who initially didn't set out to look for Mario Kart World Easter eggs but changed their plans after hearing Mario humming a tune on the character selection screen.

Only One Mario Kart World Character Hums Totaka's Song

After spending a moment thinking about this quirky feature, CharizardTelephone came to the conclusion that the character selector may be hiding even more secrets. Being aware of Totaka's Song existence and knowing that its author has also voiced the protagonist across all the Yoshi games, the player immediately scrolled over the friendly dinosaur. Sure enough, Yoshi began humming the iconic melody within seconds of the cursor idling over him.

CharizardTelephone shared their discovery on Reddit alongside some gameplay footage clearly showing Yoshi humming Totaka's Song on the Mario Kart World character selection screen. The dinosaur seems to be performing all eight bars of the melody in a rhythm that is a bit slower than the classic version, making it more difficult to identify on the fly.

A very similar—if not identical—rendition of the melody also appeared in Mario Kart 8 and MK8 Deluxe, though it was significantly harder to notice. In those games, any Yoshi character had a chance to hum Totaka's Song during races, but only on select tracks. The melody wasn’t recorded in replays, making it extremely difficult to encounter organically. Another secret that Mario Kart World shares with its predecessor is a LAN Play multiplayer mode, which can be accessed by pressing R + L + left stick while the "Wireless Play" option is selected in the main menu.
