While I was playing Minecraaft on my Xbox, the second day in my survival world with my sister, I was a flash of a black figure, I couldn't make out what it was, but I think it was shaped like a player, it was on peaceful. It was there for half a second, It was infront of a tree. The figure was completely black, This is very weird, I never seen it in my worlds, I wonder what it is, can someone tell me what it is?
