A new app has been listed up on Google Play based around coloring pictures of the mane 6 in various poses and scenes from the show. You can swap out colors to make them different, and play a few mini games throughout. Basically a new kids app.
Check out a trailer below, and the store page here where you can pre-register for it.
(Update) Apple Version up now!
Thanks to Robert and Andres for the heads up!
