I was messing around with the new 1.4 Snapshot and I took this screenshot. Looks like the Wither Skeleton is my new favorite mob.

Noooo! The whole point of 1.4 is that it's all legit! These mods arn't like tekkit or any of the mods we've seen before. They will be released with the security that Mojang themselves wrote the code.
Im going to kill loads witch will be hard as they do 3 hits then x_x You Died! and get 3 of their head drops and make a wither boss
