Yoshi and the Mysterious Book Review: A Love Letter to 30 Years of Yoshi

I was six years old when Yoshi’s Island launched on the Super Nintendo. I don’t remember the year precisely, but I remember the feeling — sitting three feet from a CRT television, watching Yoshi flutter across levels that looked like they’d been drawn with crayons and coloured pencils and infinite care. Nothing else on the SNES looked remotely like it. Thirty-one years later, Yoshi and the Mysterious Book on Switch 2 made me feel precisely that again — and this time, my own child was sitting next to me, equally wide-eyed, demanding we play the next world immediately.

Yoshi and the Mysterious Book – Nintendo Switch 2 (opens in a new tab)

The Switch 2 family game of the year. Buy it the moment you own a Switch 2 — possibly before you own anything else.

This is a 10/10. Not hedged, not conditional on being a Yoshi fan. A flat, deserved perfect score for Nintendo doing what only Nintendo can: reaching into the past, finding the soul of something beloved, and rebuilding it on new hardware with enough new ideas to feel genuinely fresh rather than cynically nostalgic. The Mysterious Book is the best Yoshi game since the original, and it isn’t particularly close.

📖 The Storybook World: Visual Artistry at Its Peak

The premise is elegantly simple: a mysterious ancient book has opened, and Yoshi must leap through its pages to rescue the stories that have been scattered across its worlds. Each world is a different chapter, rendered in a different handcrafted art style. World one looks like a child’s watercolour diary — loose, warm, joyful. World three shifts to intricate paper-cut silhouettes, all shadow and geometric precision. World five is a felt and wool tapestry, three-dimensional and tactile in a way that makes you want to reach into the screen.

The Switch 2’s hardware does something genuinely impressive here. On the OLED screen in handheld mode, the art styles are so crisp and detailed that the game looks like a living illustration. Docked to a 4K television, each world has enough resolution and shadow detail to reward close inspection — you’ll notice things on the tenth playthrough that you missed on the first. The art direction team deserves recognition that extends well beyond a game review. This is a visual achievement.

The Mysterious Book mechanic extends into the level design itself. Pages of the book physically make up the terrain — you run across sentences, leap between illustrations, and watch as the story literally bends and folds around Yoshi’s movements. In certain levels, a gust of wind turns the page mid-run, revealing a secret route behind the papery layer. It’s clever, consistent, and beautifully realised.

🥚 The Egg Mechanic: 30 Years of Polish

The core of every Yoshi game is the egg. Yoshi swallows enemies, converts them to eggs, and uses those eggs as projectiles — tossed with a reticle aim that demands both spatial awareness and a certain casual recklessness that is enormously satisfying to master. Yoshi and the Mysterious Book doesn’t reinvent this. It doesn’t need to. What it does is execute it better than any previous entry.

The aim assist scaling is precisely calibrated. With assists off, the reticle is manual and the egg arcs with real momentum — satisfying for adult players who want a skill ceiling. With assists on, the reticle snaps to nearby targets and the arc flattens slightly — making it accessible to players who might be four years old and holding a Joy-Con for the first time. Both modes produce the same tactile thwack when an egg connects, the same shower of coins and fruit, the same delighted enemy reaction. The feel is universal.

The platform Yoshi and the Mysterious Book was built for. If you're on the fence about Switch 2, this game tips the scales.

New to Mysterious Book is the Storybook Egg — a special projectile that, when it hits a story-marked surface (usually a piece of illustrated text in the background), opens a hidden page with a bonus challenge inside. These secret rooms are the game’s flex zones: more demanding platforming, timed egg puzzles, a hidden Whimsy that completes the level’s illustration. They’re entirely optional, which means younger players skip them without friction, while completionists like me will spend an embarrassing amount of time hunting every last one.

👥 Two-Player Co-Op: The Real Test

We are, as a household, big Yoshi fans since the SNES era — and this means my child arrived at the Switch 2 with opinions. Opinions about Yoshi colours (green is correct, red is acceptable, anything else is chaos), opinions about who gets to swallow which enemy, opinions about the fairness of egg distribution. The two-player mode in Mysterious Book accommodates all of this with remarkable grace.

Both players control a Yoshi simultaneously — each in a different body colour, each with their own egg supply. The innovation is the toss mechanic: either Yoshi can pick up the other and throw them across gaps that would otherwise be unreachable. It sounds gimmicky. In practice, it creates genuinely collaborative platforming moments where one player positions themselves as a living stepping stone while the other launches forward to hit a trigger. The roles constantly reverse. Neither player is the “helper” — both are essential.

For younger children, the game’s Mellow Mode (a returning favourite from Yoshi’s Woolly World) gives Yoshi wings that prevent falling into pits. This turns a potentially frustrating experience into a pure exploration game: fly freely, find the secrets, collect the flowers. Our sessions moved fluidly between standard mode for the more confident platformer moments and Mellow Mode when concentration wavered. The game judges neither choice.

🕹️ Switch 2 Features: More Than a Checkbox

Nintendo Switch 2 games are supposed to use the new hardware features meaningfully, not just slap them on as marketing bullet points. Yoshi and the Mysterious Book earns its Switch 2 designation. The HD Rumble 2.0 implementation is worth noting specifically: different egg throws have different haptic characters — a light toss feels like a gentle thud, a power throw sends a satisfying percussive pulse through the controller, and landing the Storybook Egg on a hidden page triggers a unique multi-stage rumble pattern that signals discovery before the visual effect even completes.

The GameChat integration in co-op works exactly as intended for playing with family members on separate consoles. Voice chat through the Switch 2’s built-in mic — no external app, no QR code nonsense — is the kind of obvious usability improvement that should embarrass every previous online co-op implementation Nintendo has shipped. The mouse control sections in certain puzzle rooms (using the detached Joy-Con as a pointer device on a flat surface) feel like a genuine new mechanic rather than a tech demo: you’re physically aiming Yoshi’s egg throw by moving the controller like a mouse, and the spatial translation is immediate and accurate.

🌸 Level Design: The Highest Craft

The level design in Yoshi and the Mysterious Book is, in the most straightforward terms, excellent. Each world introduces a central mechanic — weight-sensitive paper platforms in World 2, ink that spreads and recedes on a timer in World 4, shadow puppetry that flips the silhouettes of enemies in World 5 — and then iterates on it through six or seven stages before introducing the next idea. Nothing is introduced and immediately abandoned. Nothing overstays its welcome.

The boss encounters are the best in the series: each one is a puzzle expressed through the world’s art style, requiring egg throws that interact with the boss’s illustrated form in ways that feel clever rather than formulaic. World 3’s boss involves folding the paper-cut arena itself to expose vulnerabilities. World 6’s finale uses the felt-and-wool texture as a literal threading mechanism. They’re inventive, brief enough not to frustrate young players, and just difficult enough to feel earned.

🎵 Sound Design: Complete

The soundtrack is composed in the tradition of Yoshi games — light, melodic, texturally appropriate to each art style — but several tracks in Mysterious Book achieve something more. The World 5 felt theme uses what sounds like literal plucked wool strings and thumb piano, and the effect is genuinely moving in a way that’s hard to explain rationally. The egg-toss sound effects have been rerecorded and sit in the haptic register — you feel the throw at the same moment you hear it. Co-op sessions get louder as excitement builds, which is always the correct metric for a family game.

🧮 For the Completionist Dad

Every world has three collectibles per level: Smiley Flowers (the main progress item), Red Coins (twenty hidden in each stage), and a Whimsy hidden in a Storybook Egg room. Hitting the 100% mark in a world unlocks a bonus stage that is markedly more demanding than the main game. This is the correct structure for a game targeting mixed-age families: the main path is accessible to children, the completion layer is challenging enough for adults who grew up on Yoshi’s Island and have thirty years of platformer instinct to deploy.

The game does not count steps between the easy path and the completion target — but the gap is real and satisfying. We’ve finished the main story and are currently at 67% completion, which feels like a full second playthrough ahead of us. At the family gaming pace we maintain, that’s several more months of Saturday afternoon sessions.

Is Yoshi and the Mysterious Book a Switch 2 exclusive?

Yes. It is currently exclusive to Nintendo Switch 2 and requires the new hardware. There is no announced version for original Switch or other platforms.

How does two-player co-op work?

Both players control a Yoshi in a different body colour, each with their own egg supply. The key mechanic is throwing each other across gaps — making co-op genuinely collaborative rather than parallel play in the same room.

Is Yoshi and the Mysterious Book suitable for very young children?

Yes, from around age 4. Mellow Mode gives Yoshi permanent wings that prevent falling into pits, turning the game into a pure exploration experience. It’s the most accessible Yoshi game for young players.

How long is Yoshi and the Mysterious Book?

The main story takes 12-15 hours in co-op. Completing all Smiley Flowers, Red Coins, and Whimsies extends that considerably — with bonus worlds unlocked for full completion in each chapter.

Is this similar to Yoshi's Island on SNES?

In spirit, completely. The handdrawn aesthetic is a direct continuation of what made Yoshi’s Island revolutionary in 1995, and the egg-tossing core mechanic is lovingly preserved. The storybook setting and Switch 2 mechanics are entirely new — it honours the original without copying it.
