View Controls →Yoshi and the Mysterious Book is a 2026 side-scrolling platform game developed by Good-Feel and published by Nintendo for the Nintendo Switch 2.
The game follows Yoshi as he dives into the pages of a living encyclopedia called Mr. E (Mister Encyclopedia), exploring the habitats of bizarre creatures and documenting their traits.
The world is rendered in a distinctive stop-motion animation style, with painterly textures and pencil-sketch outlines giving it the feel of an illustrated picture book brought to life.
The main story spans 6 chapters, each set in a different environment. Four post-game chapters unlock after completing the main story.
Post-game chapters: Underground (285★) · Tallest of Trees (353★) · Miniworld (421★) · Moon (500★)

No. Yoshi and the Mysterious Book is a Nintendo Switch 2 exclusive and is not available on the original Nintendo Switch.
There are 10 chapters total — 6 in the main story and 4 post-game chapters. You need at least 218 stars to unlock all main chapters, and up to 500 stars to unlock the final post-game chapter (Moon).
Chapters are unlocked by earning stars. You earn stars by making Discoveries in creature habitats — each discovery gives 1 star, and completing a Big Discovery gives 3 stars. You can replay habitats to earn more stars.
Each level is a creature's Habitat. Your goal is to study the creature by interacting with it and using it to interact with the environment. Each new behavior you uncover is a Discovery, which awards a star.
Tokens are gold glyph-shaped coins collected during levels. They can be spent to unlock Discovery hints — first showing a silhouette of an undiscovered trait, then more details with additional tokens.
No. Yoshi cannot be defeated in Yoshi and the Mysterious Book. There is no health system or game over — the focus is entirely on exploration and discovery.
No. Yoshi and the Mysterious Book is a single-player only game with no multiplayer mode.
The main story (6 chapters) takes roughly 8–12 hours for a thorough playthrough. Completing all 10 chapters including post-game content and reaching 500 stars adds several more hours for a full 100% run.
