Nerfs were herbivorous nonsentient animals which originated from Alderaan. They were so nonsentient, in fact, that they could be hunted by Gungans. They were tended to by nerf herders and commonly consumed as food by many of the galaxy's inhabitants. Dishes made from nerfs included braised nerf, nerf steak, and nerfburgers. Nerfs were so common that by 0 ABY, they had virtually overrun Alderaan, and were well on their way to establishing a utopian society when the planet was destroyed by the Death Star.
