How do you become a polar bear?

It is impossible to become a polar bear unless you are born a polar bear. But you can become like a polar bear by imitating some of its distinct characteristics. If you want to look like a polar bear, you will have to make a costume of white fir, wear big teeth, and have two little ears and a little tail. You will then want to act like a polar bear, swim like a polar bear, and eat like a polar bear. But you will never mate with a polar bear or make little baby polar bears.
