Yoshi and the Mysterious Book at a glance:

  • A platformer starring Yoshi from the Mario series.
  • Rated E for Everyone with a Content Descriptor for Mild Fantasy Violence.
  • Gameplay centered around exploration and observation may be attractive to younger players.

There’s a lot of excitement for Yoshi and the Mysterious Book in my home. Not from my one-year-old, but from my wife. Over the years, Yoshi games have become events: We’ll order takeout, charge up our controllers, and plow through any Yoshi game together.

If you’re on the fence about whether the next installment starring Yoshi is appropriate for your family, here’s a full rundown to help you decide!

Is Yoshi and the Mysterious Book Appropriate for Kids?

Yoshi and the Mysterious Book is rated E for Everyone, with a Content Descriptor for Mild Fantasy Violence. This means that any violence in the game is minimal, and very easily distinguishable from anything one would experience in real life.

For some more in-depth information, ESRB’s Rating Summary explains that “enemy creatures may dive towards Yoshi, resulting in brief yelps of pain (though no lasting damage/injury occurs); Yoshi can toss eggs or rocks at objects and enemies. Boss battles/challenges depict more protracted combat, with cannonballs and/or objects hitting larger creatures.”

Friendly reminder: A game’s rating category is based on what you may see or experience while playing in a game. It does not change depending upon the challenge or difficulty of a game. So, just because Yoshi and the Mysterious Book is rated E for Everyone does not necessarily mean players of all ages will be able to play without frustration. However, Yoshi games do tend to be inviting for younger players, and often include various settings and handicaps to help all ages enjoy the play.

Where Can I Play Yoshi and the Mysterious Book and How Much Does It Cost?

Yoshi and the Mysterious Book is available only on the Nintendo Switch 2. The game costs $59.99 for the digital version and $69.99 for the physical version.

What is Yoshi and the Mysterious Book About?

What would Yoshi and the Mysterious Book be without both the titular character, Yoshi… and a mysterious book?! The story begins as Yoshi and his pals enjoy their island paradise, only to find a talking book falling from the sky. The book – named Mr. E (short for Mr. Encyclopedia) – is chock full of blank pages that used to house information about all sorts of creatures.

An image of the inside of a book with faded brown pages. The pages feature a daisy-like creature, along with how that creature helps Yoshi interact with the environment. This includes blurbs like "Makes flowers bloom," and "Rides on Yoshi's Back."

Mr. E cannot actually read the pages to learn about said creatures. You see… Mr. E’s eyes are on the front cover of the book, so the contents of his leather-bound body are a mystery! Yoshi agrees to help research the creatures by jumping into Mr. E’s pages and exploring.

Oh my gosh… Mr. E… Mystery. I just got that!

How Does Yoshi and the Mysterious Book Play?

Yoshi and the Mysterious Book arms Yoshi with a toolkit of moves that may be familiar to anyone that has played a Yoshi game in the past. Yoshi can jump, ground pound, and swallow creatures with his prehensile tongue. Yoshi and the Mysterious Book adds a “tail flick” to the arsenal, which hoists an enemy or creature onto Yoshi’s back when it makes contact.

Crazee Dayzee is rising on Yoshi's back in a storybook-like world. CrazeeDayzee is a daisy with little green legs and a smiling face. Behind the pair, text appears under a bed of flowers that says, "Makes flowers bloom!"

The objective is not to defeat enemies, but rather to learn about creatures. You and your kids can guide Yoshi to interact with creatures to unlock Discoveries. Let’s walk through how this works with an early creature called Crazee Dayzee.

As you experiment with Yoshi’s moves, you’ll unlock more information about Crazee Dayzee:

  • Crazee Dayzee is light, so it can ride on Yoshi’s back.
  • When Yoshi licks Crazee Dayzee we discover that it tastes sweet.
  • If Crazee Dayzee is on Yoshi’s back and they run past some budding flowers, they will bloom.

These are just a few of many Discoveries about Crazee Dayzee that Yoshi can record in the into Mr. E’s pages. You and your kids can then leverage how these creatures interact with the environments to traverse the world, unlock more creatures to research, and learn how each creature interacts with others within Mr. E’s pages.

With enough Discoveries, you and your kids will unlock additional chapters with more complex challenges and interactions between creatures.

As mentioned, most of the gameplay is not aggressive, and environments are intended to be explored rather than conquered. Yoshi does not have health and the creatures you find are not your enemies. Even so some creatures will go after Yoshi, but Yoshi will simply emit a little yelp if hit and carry on with adventuring.

Keeping Your Kids’ Discoveries Age-Appropriate

Setting your kids up for fun, age-appropriate experiences is not always the most straightforward process. Fortunately, there are tons of resources to help you streamline that.

Unsurprisingly, I always recommend checking the ESRB-assigned rating information first. The age and content ratings provide a great, familiar, and trustworthy look at what to expect from a video game. All games that are available physically (in a box that you’d order online or pick up in-person from a store) also have Rating Summaries, which provide a lot more contextual information about why a game received the rating it did.

Of course, sometimes you’ll want more information. For most games you can find gameplay videos, previews, trailers, and more with a quick internet search. Many games also have demos that you can play yourself to get some first-hand experience with a game before giving the green light to your kids.

We also recommend establishing some commonsense household rules around video games in your home. Talking to your kids about what they like about their favorite games will help you better understand which rules work for them. Check out ESRB’s Family Gaming Guide for some tips and conversation starters.

You can back these rules up with parental controls, too. All devices capable of playing video games offer parental controls settings. You can activate these to manage what your kids play (based on the ESRB rating information), when and for how long, with whom they can play online, and whether they can spend money on new games or in-game purchases. ESRB has step-by-step parental controls guides for many of the most popular consoles and devices at ParentalTools.org.
