Pokemon turns 20 today, and there are a lot of ways to celebrate — but none are as good as watching an entire day's worth of the anime. Starting tonight at 9PM ET, an official Pokemon Twitch channel will be holding an animation marathon, broadcasting 24 straight hours of movies and shows. Earlier today, starting at 1PM ET, a separate Pokemon channel began by showing a variety of gameplay footage and interviews to celebrate the special date. Maybe it'll even include a glimpse at Pokemon Sun and Moon, which were just announced yesterday. And if you're looking for something to do while you watch, the original Pokemon trilogy of Red, Blue, and Yellow are available starting today on the Nintendo 3DS.
