Sand People

Sand People were a germophobic race of sentient silicon-based humanoids native to Tatooine. Despite a reputation for engaging elaborate philosophic dialogs, they only spoke in gargles and grunts to outsiders. Sand People wore sack-cloth robes and frequently showered themselves in ashes leading some ethnologists to theorize that they were in mourning. However, when approached to learn the truth of this, Sand People would run them over with turbo-charged banthas.
