OH DEAR GOD
I'm on easy (i can't stand the creepers on any other setting) and i was looking at 2 skeletons with an iron sword,ready to kill them for arrows,when suddenly (i had my sound off) i go and look at a zombie and SUDDENLY CREEPER and the creeper annihlated a tree i was hiding behind and a mound of dirt.
I wasn't harmed,thanks to my combination of gold,leather,and iron armor,which only took half a armor piece.
EDIT: Then the skeletons chased after me,i did some damage to both of them and one shot the other and they got into a battle,in which the one standing in front of me won,conveniently.
