Cave skettos, or simply skettos, were a species of non-sentient, ferocious flying pests found on the desert planet of Tatooine. Capable of growing up to one meter, they boasted four powerful legs, a prehensile tail, four wings, a mouth full of fangs, and eyes that provided excellent night vision. They spent the daytime sheltering from Tatooine’s twin suns before emerging in swarms at night to feed on smaller airborne critters and suck the blood of larger sleeping animals.
