Nope, it's from Twitch Plays Pokemon. The pokemon depicted as ghosts you see here were accidently released by the 50,000+ people that were all trying to control the game by inserting commands into the chat. They've beaten the original Pokemon Red and Crystal. In following 5 days, Emerald will be next. But for the time being they're playing other games while the rom is being prepared.
