How many legs does a polar bear have?
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…
Polar bears move just by walking around with their legs. They are also very good swimmers, though they tend to use the "doggy-paddle" style of swimming where they are using their front feet and legs as propellers and their hind legs as rudders (and a bit to propel them as well) as they swim on the surface of the ocean.
