It’s been a busy 24 hours for Yoshi fans. Yesterday, Nintendo confirmed Community and Star Wars actor Donald Glover would provide the voice for its elastic-tongued dinosaur in the upcoming Super Mario Galaxy Movie. Now, we know when Yoshi’s next game will release.
Yoshi and the Mysterious Book, a sidescrolling platformer exclusive to Switch 2, will arrive on Thursday, May 21.
Nintendo made the announcement today initially via its Nintendo Today app and then across social media, in celebration of this being Mario Day (because March 10 looks a bit like Mar10). There’s also a new trailer to watch, which offers our best look yet at gameplay.

Today’s trailer introduces us to Mr. E, a talking encyclopedia, whose pages are full of odd creatures. Diving into the pages from the book will see an adorable inky Yoshi leap in and observe the animals for himself. And by observe, of course, we mean swallow.
Thankfully for the frog found in today’s trailer, Yoshi soon decides the animal isn’t particularly tasty. After spitting it out, the frog will gamely blow bubbles for Yoshi to hop into and ride, allowing for some quick platforming. By feeding the frogs different foods, you can create different kinds of bubbles, and unlock further discoveries about the species. You can also name the species yourself (which we’re sure players will be completely normal with).
As you progress further through the game, new environments and many more creatures will be unlocked for Yoshi to research. And at the end of the trailer… there’s a reveal that Bowser Jr. will somehow be involved in the proceedings too.
Yesterday’s Super Mario Galaxy Movie-focused Nintendo Direct confirmed Glover as Yoshi, plus Wednesday star Luis Guzmán as Wart, and Issa Rae as Honey Hive Galaxy’s Honey Queen. We also got to see a good chunk of new footage from the film, as Bowser Jr. begins his own diminuitive reign of terror.
