If you've been itching to pick up the Pokemon TV App, you can now grab it on Kindle devices. It'll feature over 700 episodes of the show, and although they cycle, you can watch a metric boatload of Pokemon at all times. The app is also updated constantly with new content and trailers (like the upcoming movie).
You can pick it up for free if you want, so don't worry about a subscription or anything like that. Gotta catch 'em all!
