INFO: The Hoovers were a small, quadruped sentient species, little-known throughout the galaxy. They were brown with black eyes and disproportionately large trunks; with this, some sucked the blood of other sentients. Hoovers could become sophisticated technicians, utilizing their tiny size to effect repairs from inside machinery. The technician Attark was a pet of Jabba Desilijic Tiure, living in the Hutt's Palace on Tatooine in 4 ABY.

BIOLOGY AND APPEARANCE:The Hoovers were a sentient species of quadrupeds with each of their limbs ending in black, cloven hooves. They had a disproportionately long snout compared to their small body size. Hoovers could use these snouts—also known as nose trunks—to slither through clothing and around blankets. It also enabled them to suck the blood of sleeping victims, belying their otherwise harmless appearance. They had two large, black, pupiless eyes, pointed ears, a wide mouth, and a small tail. A narrow ridge began at the top of their heads and ran down their backs to their tails. At least some Hoovers had brown skin, which was heavily wrinkled.
CULTURE AND HISTORY:To the wider galaxy, the Hoovers were a mysterious and little-known species. They were part of the the galactic community by at least 4 ABY, when the Hoover Attark was a member of the Tatooine court of the Hutt crime lord Jabba Desilijic Tiure. Although considered to be a pet of the Hutt, he had tremendous technical abilities, and, due to his small size, was able to manipulate detailed electronics, sometimes crawling inside machinery to repair it from within. During the night, Attark drank the blood of other members of Jabba's retinue. He was present when Luke Skywalker, Leia Organa, and Chewbacca infiltrated Jabba's Palace to rescue a carbonite-encased Han Solo, an event which subsequently led to the death of Jabba and the splintering of his criminal empire.
