Yoshi and the Mysterious Book releases May 21, 2026

Nintendo announced today that Yoshi and the Mysterious Book will release on Nintendo Switch 2 on May 21, 2026. The announcement comes with a trailer and obviously on Mario Day. 

Below is an overview of Yoshi and the Mysterious Book via Nintendo:

Play as Yoshi and discover quirky creatures in the pages of a talking book named Mr. E!

Mr. E needs Yoshi’s help to remember all about the creatures living inside his pages. Open him up, explore each habitat, and experiment to learn about the creature that lives there. What does it do? What does it taste like? How does it interact with its environment? How will it react if you smash it, carry it around, or give it a piece of fruit? There’s only one way to find out!

Make discoveries, collect Stars, and…hey, what’s Bowser Jr. doing here?!

As you try new things with each creature, you’ll naturally make discoveries, clear habitats, collect Stars, and unlock more pages to explore. You can even give each critter a name!

But what’s this? Bowser Jr. is also popping up in these habitats?! What could he be up to?

Yoshi and the Mysterious Book will only be available on the Switch 2 and will cost $60 for the digital and physical versions of the game.
