If you have any interest in the Mixels toys or cartoons, you might be interested to know that there are two official games on the Google Play store (I happened to spot them there a little bit ago, I imagine they are on itunes as well). The first is Mixels Rush, and the other Calling All Mixels. Both games are free, though supported by in-game advertisements, and Calling All Mixels is listed as having in app purchases.
