Mountain Nerf
this species of nerf evolved on the planet Fennesa, after a group of colonists brought them to the rocky world. Originally from the main stock of nerfs from the planet Alderaan, mountain nerfs on Fennesa have adapted to life in mountainous terrain over several thousand years. This led to a problem for the colonists, as the nerfs were able to hide in the crags and crevices of the mountains and were hard to capture for shearing or slaughter. The saliva of the mountain nerf contained an acidic compound that helped them digest food. This saliva was not poisonous to the colonists, but could produce a burn on the skin if not washed away.
