Wol Cabasshite / Legends Wol Cabasshites were sentients originating on Wol Cabassh . Evolving from a non - sentient parasitic species , the Wol Cabasshites could survive in vacuum due to their genetic makeup , making them widespread across the galaxy by the Imperial Period . Their culture was built entirely on philosophy , rather than technology , and for communication they were able to exude a magnetic field wherein they " sang " to one another . This led to confusion amongst the other sentients of the galaxy , and the Wol Cabasshites soon came to be regarded as " bizarre . " Their texts would be studied by the intellectual elite of the galaxy , and apparatuses were invented to allow Wol Cabasshites to properly interact with other sentients , but the dual - brained sentients instead preferred to simply eat and muse about the nature of the universe . Several Wol Cabasshites rose to prominence in galactic history , the most famous being Jedi Master Omo Bouri . Biology and appearance . Measuring approximately 0 . 8 meters long in standard configuration , Wol Cabasshites were small , hardy creatures that could survive in both vacuum and atmosphere due to the fact that they lacked a respiratory system . Their internal organs were contained within a naturally - pressurized chamber , which was also resistant to extreme temperatures . Most of their body was made up of a large stomach ; Wol Cabasshites also possessed two brains , one for digestive purposes and the other to govern cognitive functions . Wol Cabasshites had high - plasma diets , and as a result , had a highly metallic content level in their blood . They extracted metals and nutrients from everything and anything they came into contact with . There were no known substances considered toxic to Wol Cabasshites , but they were especially susceptible to Brainworm Rot Type A , an airborne virus that afflicted their cognitive abilities . Wol Cabasshites reproduced by expelling their stomach linings , which became pupal Cabasshite . Adults were also able to exchange genetic material by grooming each others ' tongues ; in these instances , the offspring would feature isolated genetic properties of their " parents . " Using internal muscles , Wol Cabasshites could radiate a magnetic field with a twenty - five meter range . This field was used for communication between Wol Cabasshites , as they would use phonemic pulses of energy with syntactic contours within radius . The communication often came in the form of singing , but when it came to communicating with other species , the Wol Cabasshite would have to be in direct contact with said sentient . This was often unsettling to foreign sentients . Society and culture . The Wol Cabasshites , unlike contemporary cultures of the galaxy , did not build their civilization on technology , but rather , philosophy . They recorded several texts , which were a cause of curiosity in other sentients . Magnetic singing was one of the most important aspects of Wol Cabasshite culture , as it was their primary form of communication . Sentients developed apparatuses that enhanced or allowed the Wol Cabasshites locomotion , communication , and defense , but most were content with either simply eating , or contemplating the nature of the universe . History . The Wol Cabasshites first evolved from parasites , and after millennia of spacefaring along with their non - sentient plasma leech cousins , they found themselves widespread across the galaxy . The musings of their culture soon became an object of interest for the self - styled intellectual elite of the galaxy , but the Wol Cabasshites at large were a largely misunderstood race , with their texts being regarded as " bizarre . " The ability held by select Wol Cabasshite to communicate with other sentients upon contact caused great speculation , as the ordeal was said to be uncomfortable by the non - Wol Cabasshite . Rumors abounded that the Wol Cabasshite could control the brains of other sentients . Due to the fact that Wol Cabasshites were largely indecipherable by other cultures , several different communication devices were developed by non - Wol Cabasshites . These went largely ignored by the Wol Cabasshites , however . When Wol Cabasshites were afflicted by Brainworm Rot Type A , it was considered difficult to diagnose , simply due to the nature of Wol Cabasshite anatomy , and the lack of familiarity amongst other sentients . In 22 BBY , Wol Cabasshites and Anomids on Coruscant were severely affected by an outbreak of Brainworm Rot Type A in the Manarai Heights region , though the Coruscanti officials were able to contain it . In 1 ABY , a thriving batch of Brainworm Rot Type B was discovered in a ronto lair on Tatooine . Fearing that it would evolve to Type A and wipe out Tatooine ' s Wol Cabasshite populace , Ambassador Lurll hired a spacer to clean out the lair and quarantine the virus . Wol Cabasshites in the galaxy . One of the most famed Wol Cabasshites was Omo Bouri , the Jedi Master who taught future Jedi Council member Saesee Tiin and orchestrated the Treaty of Trammis in 124 BBY . Tiin , a natural telepath , found it difficult to communicate with Bouri , as he found the Wol Cabasshite method of communication to be highly alien . Tiin would reflect upon this as being a refreshing experience for someone who could instantly read the mind of most sentients . In 1 ABY , Wol Cabasshite ambassador Lurll hired hunters to kill several batches of creatures known to be carrying Brainworm Rot Type B on Tatooine . During the Imperial Period , the Wol Cabasshite Ghoel took up residence in Jabba ' s Palace on Tatooine . No one suspected his intelligence , as he was immobile . He would often try to lick passers by , presumably to communicate with them . Behind the scenes . The Wol Cabasshites first appeared in Richard Marquand ' s , where they were shown , fleetingly , in the Jabba ' s Palace sequence . Their name appeared in 1983 as part of the Airfix " Jabba The Hutt Throne Room Action Scene " kit , and was later retreated in the " " Jabba ' s Palace Limited " " set of the " Star Wars " Customizable Card Game . The backstory and elaboration of the species was provided by " ejmacki " through StarWars . com ' s feature , " What ' s The Story ? , " which worked with information provided in the card game . The " What ' s the Story ? " information would later be used by Ryder Windham in his 2007 reference book , " " , and in 2008 ' s " The Complete Star Wars Encyclopedia " .
