Overgrown mane is another type of mane mutation which causes the fur of an organism to spurt. When the cubs are born it is impossible to stop the growing fur. Once it reaches adulthood it's obvious the organism has extremely long and thick fur. The fur grows all over the body which can cause easy tripping and loose objects to get stuck in the fur, although the overgrown mane is not lethal and the organism usually has a normal lifespan.
