I though that the NPC villagers are U.G.L.Y and chances are so did you! And thats why YOU are HERE to fix this ugly bug in Minecraft and replace them with a civilization of big headed creepers I even made up some lore just bear with me some more.

Some Creepers started thinking if there is more to life than walking around aimlessly and exploding during their time thinking they gained something valuable. A brain but in the process the explosive powder in their heads has disappeared too, because of this they where known as outcasts and decided to build their own civilization and as the years went on they have evolved. Grew hands and their bodies changed, learned how to speak and most importantly they learn how to build. Not destroy.

Yeah okey I am done and am Satisfied that those things will not pollute my world any longer!
