If you could have any animal's hair, whose would you choose? If you chose a polar bear's double couat, you would never have to wear a hat when playing in the snow. If you had a reindeer's hair, it would help you stay afloat in water. And if you had a porcupine's hair, no bully would ever bother you again! The animal kingdom has lots of awesome types of hair, but yours is pretty great, too!.
