Birch

Birch is a dark chestnut colored she-wolf with white markings that consume most of her body's color. She has a black nose and red skin. She was named after the complex carbohydrate, cellulose. Sometimes, when she passes her pack members, she can hear them say, "Oh lord, not this Birch again!". Wait, I she her name was Cellulose? But Birch trees are made of cellulose, right? Cellulose suspects that Birch may also be her name, and has therefore started responding it it.
