Yesterday at 8:30pm, Stevie (my 9-year-old sister) saw something on the menu screen on a lily pad. It was all pitch-black. The next time she saw it, when she was in a SMP (survival multiplayer), she saw it again, which was strange, because she didn't invite anyone. Repeat: anyone.

The next time, while I was with her, she saw it again. This was from a ruined portal, and the top half of the... *ahem*... thing was Entity 303 and the bottom half was, once again, pitch-black. The next time, when she was in her base, it supposedly nearly killed her in-game and splashed an invis potion on itself, then nearly burned her base to the ground. She deleted the world after that.

It must be some sort of demon that the developers accidentally created out of a villager, player model, etc., so don't put in the same seed Stevie did. (1124791)
