THE COWS USE SPEARS
(okay those were voulge/bardiche but whatever still look spear-y enough to me)
I think the question is how a cow can walk on two legs and hold a polearm at the same time with it's hoofs?
They are not actually cows, btw - no udders! They are bovines, hehe
EDIT: LOL the ninja text got me, read it too late haha
