Before 4 ABY , the Imperial Oplovis sector fleet was in the Yuvern system and engaged a fleet belonging the Rebel Alliance . Adiss observed the battle from a starship of his own as the Imperials were overwhelmed and fled the system . Behind the scenes . Cane Adiss is the only Yuvernian to appear in " Star Wars " media to date , having debuted in Richard Marquand ' s 1983 film as an unnamed background puppet . He can be seen in at least one shot , when Chewbacca is being led from Jabba ' s throne room by a Gamorrean guard . However , the book " " claims that Adiss did not make the final cut of the film . The CD - ROM " " similarly asserts that the Adiss puppet was built for the film but is only seen in its " " reference book . The puppet was initially painted orange with dark orange spots , and during production of the film , was the subject of a joke between Industrial Light & Magic employees . During a photoshoot of their creature shop , they hung a " NO HUNTING " sign on one of the puppet ' s necks . Adiss ' s species was not identified as Yuvernian until 2006 , when his backstory was developed for StarWars . com ' s Hyperspace feature " What ' s The Story ? " by John Hazlett ( writing as " jSarek " ) . Hazlett established Adiss as a Yuvernian from Yuvern , a planet that had been introduced in 1990 ' s " Rebel Alliance Sourcebook " . To this day , no photo or description exists of Yuvernians below their necks . Hazlett originally gave additional details regarding the Yuvernian parental collective in his entry , including the fact that all adults of the species were required to look over a year ' s hatching of Yuvernian eggs in any given community . He also surmised that in the collective , the year of an egg ' s hatching was more important than the identity of the egg - layer . Realizing that he had to detail these facts unobtrusively in the context of Cane ' s life , Hazlett cut them early in the writing process .
