Happy Mario Day! On this day where we celebrate the birth of one of video gaming’s oldest icons comes news that Yoshi and the Mysterious Book, the upcoming 2D title featuring everyone’s favorite green dinosaur, now has a release date. Per Nintendo, Yoshi and the Mysterious Book will be released on May 21st, 2026, for the Nintendo Switch 2.
Yoshi and the Mysterious Book is a lighthearted platforming adventure that drops Nintendo’s favorite green dinosaur into a magical storybook world. After discovering a strange book, Yoshi is pulled inside and must travel through its pages, with each chapter becoming a colorful stage filled with puzzles, enemies, and secrets.
Using familiar abilities like egg throwing and flutter jumping, Yoshi helps restore the story while uncovering why the book’s pages have started to change. It’s a charming, easygoing adventure that leans heavily into that classic Nintendo style of bright worlds and playful exploration.
