When Spirit was born he was special. Unlike Permafrost, Frostbite had a Mutated pup with a different look. He was Albino. The pale skin and red eyes were a clear sign of that. His fur was so white it had an unearthly glow to it that made him look as if he was a ghost. He was definitely a stand out pup compaired to his sister Moss who blended in with her suroundings.
Even though he stood out so much due to his special look he was treated just the same as any other wolf in the pack. He had a positive outlook on life which was ironic given his undead apperance.
At times outside wolves who wondered into the pack teritory would be scared by his apperance and think he was indeed a spirit due to his look and unearthly glow. It was almost too good of a defence. When he wasnt "scareing" wolves with his ghostly aperance he was hunting with his mother, aunt, and patches which he had unoficially labled as his uncle.
