The Nerf is a pack animal, a bit like a bison, they have curved horns and long fur. The animal is also used for meat. It was first mentioned on Star Wars Ep.4 and it is meant to live on the planet Alderaan. The long fur tangles and mats really easy and because of this it get insects and things sticking to it and makes it smell pretty bad. Shepherds that raise nerfs are called nerf herders.
