Fosh The Fosh were a sentient avian species from an unknown world , possibly hailing from the Corporate Sector . Biology and appearance . The Fosh were bird - like creatures with slim torsos and delicate arms tipped with four - fingered , talon - like hands that evolved over tens of thousands of years from wings . Due to the frail nature of their bodies , Fosh tended to shy away from conflict and confrontation . Their necks in particular were most vulnerable , and were reflexively guarded during combat . They were , however , agile creatures with a typically avian stance and flay - toed feet useful for jumping . The Fosh had a convex face ending in a beak - like mouth , around which were tufts of soft whiskers . The head of the Fosh was capped with two twisting antennae , the use of which remains unknown , and a feather - lined ridge protruding from the skull . These feathers shifted color depending on the Fosh ' s mood : Green indicated inquisitiveness , thoughtfulness or amusement ; orange was a sign of happiness ; and gray was anger , disgust , irritation or seriousness . One of the most intriguing aspects of the species was the chemical makeup of its tears . Female Fosh especially had lacrimal glands that enabled them to alter their tears to produce a variety of pheromonal substances that affected males during mating . The Sith apprentice Vergere had such a control over her tears that they could , with the aid of the Force , be engineered to produce any number of chemical substances ranging from poisons to healing fluids more powerful than bacta . Society and culture . The Fosh as a people were very private , preferring to remain unnoticed by the larger galaxy . They commonly spoke only on matters of great importance , content to simply listen at other times . It was believed that the Fosh population was small , although this may simply have been an effect of their ability to conceal themselves from other species . The Fosh were , however , adept at political intrigue , and culturally , they were a manipulative species similar to the Bothans , but much more devious — many Fosh were bigots , looking upon other races as inferior , sometimes even as toys for their own amusement . They would create plots within plots to achieve either highly complex or at times very simple goals . They spoke indirectly to others , rarely revealing their true desires , and were fond of riddles and analogies designed to confuse and confound . Because of this , the Fosh were a highly self - serving , self - interested species that was only generous when their actions hid an ulterior motive . The Fosh were , however , wise enough to spot the dangers inherent in other species , and were vigilant in their dealings with outside races . History . Due to their secretive , private nature , Fosh were little seen in the galaxy at any point in its history . It was possible that the species was one of those targeted for extinction by Emperor Palpatine , though even as of the decade prior to the Clone Wars , the species was considered to be largely extinct . The only notable Fosh to have an impact outside of the species ' homeworld was the Jedi Knight Vergere , active during the final decades of the Galactic Republic . After the Yuuzhan Vong attacked Zonama Sekot , Vergere traveled with the alien invaders for many years , ultimately returning to the civilized galaxy with Jacen Solo . Up until this time , even New Republic Intelligence was not aware of the species ' existence . However , Droma once saw a Fosh in the Corporate Sector . Behind the scenes . The Fosh pictured in " The New Essential Guide to Alien Species " has knees that bend like a humanoid ' s , however it is stated that they bend backwards like a crane ' s . As with most vertebrates , this joint is actually the ankle , rather than the knee .
