Nintendo has finally announced a release date for Yoshi and the Mysterious Book to celebrate Mario Day (March 10th, or MAR10) today.

Yoshi and the Mysterious Book is set to launch this spring on May 21st for the Nintendo Switch 2.

Here’s a rundown on the previously announced game, plus a new trailer:

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?
