Quockran The Quockrans were a sentient species of slugs native to the planet Quockra - 4 . The species had a large , fat body that tapered to a tail . Their torso also had two arms , ending in stubby digits . The black - skinned Quockrans had no differentiated internal organs . During their evolution , their homeworld was a moist planet . Nevertheless , the climate changed , becoming dry and hot . This drove the Quockrans ' society underground , apart from short forays to the surface . The Quockrans were a xenophobic species , desiring isolation from all other species . When the Minos Cluster was colonized late in the administration of the Galactic Republic , offworlders reached Quockra - 4 . The Quockrans responded to this violation of their isolation by manufacturing an entire society of droids to act as intermediaries with the offworlders . These droids traded with offworlders , largely keeping the existence of the Quockrans a secret . Biology and appearance . The Quockrans were a sentient species of giant slugs . Their bodies had a large , fat torso that tapered to a tail marked with large rolls of fat . Quockrans averaged between 1 . 4 and 1 . 7 meters in length , although some had the ability grow as long as two meters . The Quockrans had a significant paunch and large drooping breasts . They had two arms that ended in four stubby fingers . The slug - like creatures had black skin , with splotches and other growths running down their midline and tail , as well as down the top of their arms . They had no differentiated internal organs , which limited the injury a single wound could do to their bodies . Quockran heads appeared knobbly . Each Quockran had a nose high on its forehead , with its eyes below this , one on each side of its heads . Below its nose was a large mouth , filled with sharp teeth . Quockran chins were large and drooping . Society and culture . The Quockrans were a xenophobic species , avoiding contact with other species if at all possible . While they despised offworlders , this rarely manifested as violence toward them . They were indifferent to galactic affairs and refused to get involved in political causes such as the Rebellion . If a Quockran was forced to interact with other species , they were surly and uncooperative , preferring , simply , to be left alone . To facilitate their isolation , the Quockrans manufactured an entire society of droids to interact with offworlders in their homeworld ' s sole city . Composed of thousands of different designs , both Imperial models and other , more exotic styles , and numbering over ten million individual units , the droids appeared to manage all the affairs of Quockra - 4 . The automata followed a clearly delineated hierarchy : three - armed yellow repair droid s were superior , giving out orders in their machine language ; red worker models were in the middle ; Imperial droids were at the bottom , functioning as translators for those of higher rank . With this system in place , the Quockrans were able to live far below ground , only emerging on the surface at night to loll about in the cooling desert sands . History . The Quockrans evolved on Quockra - 4 , the fourth planet in the Quockra system , located in the remote Minos Cluster of the southern Outer Rim Territories . The planet was originally moist , and the Quockrans lived on the surface . The climate changed , however , becoming a homogeneous desert , with several large salt flats . The surface temperature reached polar extremes , with soaring highs during the day and frigid temperatures at night . This drove the Quockrans deep underground , although they still occasionally emerged at night to enjoy the cooler , damper air . When the Minos Cluster was colonized , late in the administration of the Galactic Republic , the Quockrans created a droid society to interact with the newly arrived offworlders . The Quockrans used these droids as intermediaries for trading , and most inhabitants of the Minos Cluster were unaware the species existed . Any who were aware of the Quockrans ' existence and who tried to interfere with their affairs quickly found themselves in trouble . Shortly after the Battle of Yavin , a researcher from the Core Worlds tried to discover the " real natives of Quockra - 4 . " To facilitate his research , he offered a reward of up to 3 , 000 to traders for information on the architects of the exotic droids on Quockra - 4 . This led to some adventurers exploring tunnels below the planet ' s surface , encountering numerous groups of droids along the way — who progressively ignored them , ordered them to leave , and finally attacked them — before discovering Quockrans . These Quockrans refused to communicate with the adventurers . Behind the scenes . The Quockrans were created by Mark Rein - Hagen and Stewart Wieck for " " , a roleplaying game sourcebook published by West End Games in 1990 . This book , and its , include an adventure seed in which players try to discover the Quockran species , although no canon ical ending for this encounter is specified . This information was republished , albeit slightly condensed , in " Alien Encounters " in 1998 . " Alien Encounters " changes their height from the two meters established in " Galaxy Guide 6 : Tramp Freighters " to 1 . 4 – 1 . 7 meters . " Alien Encounters " also includes an illustration of a Quockran . The image used is a reworking of early concept art by Ralph McQuarrie of the character Jabba Desilijic Tiure , who appears in , first released in 1983 , and who has been identified as a member of the Hutt species . The concept art was published in " " later that same year . A mirrored version of the same image by McQuarrie is included in " Monsters and Aliens from George Lucas " , a non - canonical work published in 1993 , which collects concept designs created in various George Lucas projects . This book accompanies the image with a small blurb in the form of a personal advertisement . This identifies the species as a " Ytha " and requests a " hard - shelled creature for friendship / possible relationship . " In the West End Games roleplaying game , Quockrans are given statistics for players to use them as their own characters . Compared with the average Human , their perception attribute is slightly higher , while their technical skills are significantly higher . Their knowledge and dexterity scores are slightly lower than Humans , while their mechanical - and strength - based attributes are significantly lower . An exception is made to this low strength score when resisting damage , for which their score is significantly higher than the average Human .
