When I was in the deep North, by the edge nearest of the North Pole I was attacked by what I thought was the great white grizzly bear that I was hunting for centuries...Nay, it was a regular polar bear although there was something peculiar about it..we fought for countless hours with his claws and my steel spear, it was an equal match for the polar was quick on his four feet, occasionally he would let out this roar of to which I thought was a call or a cry for help. 6 hours after this event happened his polar bear buddies came by and gained up on my so I tried to make the best penguin screech I could. Eventually this worked because I could see a whole flock of those flightless monsters. 3 hours later there was a war between the polar bears and the Penguins. So yes, I have had my fair share of fighting polar bears.
