A lot or a little?

The parents' guide to what's in this game.

Positive Messages

The bare-bones story in this game revolves around overcoming great obstacles in a selfless quest. The focus isn't the story, but it does help create a sense of happiness and adventure. 

Positive Role Models & Representations

Players embark on this colorful journey alone, and their character acts as the sole potential role model. There is little in the game upon which kids might realistically model behavior, but the primary objective -- to rescue a captured friend and thwart the plans of the evil Dr. Strangelove -- is a noble one.

Ease of Play

Most young players should be able to make their way through the game without too much difficulty. Typical of the genre, there are a lot of puzzling twists and turns, and some players likely will need to play through some levels a few times before figuring out exactly how things work.

Violence & Scariness

Throughout the course of various side-scrolling levels, players will encounter colorful, non-human, fantastical "enemies." Players can attack these enemies to remove them from the level. There is little sense of any seriously violent aggression, though; the enemies just exist as a hazard to make the game more challenging.


This game exists to grow the brand of the Moshi Monsters website, which encourages players to make digital purchases to enhance their online experience. The game contains a digital code that allows players to unlock content on the website.

What parents need to know

Parents need to know that Moshi Monsters: Katsuma Unleashed is a platformer game in which players run and jump through a variety of brightly colored side-scrolling levels. The game is based on the popular Moshi Monsters website and online community and includes a special code that can be used to unlock content on the website. In line with other games of this genre, players can attack whimsical enemy creatures that disappear when hit. There is no gratuity or aggression at all in this low-level violence. The enemies are simply among various hazards found throughout the game meant to add a layer of challenge.

What's it about?

MOSHI MONSTERS: KATSUMA UNLEASHED puts players in the role of a colorful Moshi Monster who sets out on a side-scrolling adventure to rescue friends kidnapped by the evil Dr. Strangelove. After players complete the main story, they can continue to play a handful of mini-games. But this game doesn't exist to tell a compelling story so much as it does to expand the Moshi Monsters experience to a media beyond the website that originally created the franchise.

Is it any good?

Moshi Monsters: Katsuma Unleashed doesn't bring anything drastically new to the table, and it won't go down in history as one of the all-time greats of its genre. That said, it succeeds modestly in its ambition to be a fun and colorful adventure for its young target audience. The game uses a tried-and-true formula with basic gameplay, colorful graphics, and smooth controls. Players who are already fans of the Moshi Monsters website will enjoy the familiar characters and themes. And, to its credit, the game does a good job of living up to the well-designed aesthetic and charm of the website. On its own, though, it doesn't really stand out among the many great side-scrolling platformers available for Nintendo 3DS.

Talk to your kids about ...

  • Parents can discuss this game's apparent consumerism via its promotion of a paid website. Does this game make you want to spend more time on the Moshi Monsters site? Is that a good or a bad thing?

  • Have you ever been in a tough situation in which you thought the odds were against you? How did you handle the situation?

  • If your friends were in danger, what would you be willing to do to save them?
