Mynock / Legends A mynock was a silicon - based parasitical organism found across the galaxy that was often seen leeching power from spacecraft . In addition , they could absorb matter from a ship ' s hull causing it to breach , and if not caught in time , cause catastrophic failure . Anatomy . Mynocks often attached themselves to passing starships to chew on power cables . A drop in the power of the hyperdrive could increase the travel time . They were considered parasites by pilots and starport personnel , and failure to properly shake them off in orbit before landing could result in quarantine . Mynocks were one of the few species that could live in the vacuum of space . They had bat - like wings which they could use to fly in atmospheres . However , they were often limited to the vacuum of space due to an allergy to helium found in the atmosphere of many planets . This allergic reaction would cause them to inflate and nearly explode before dying . Many spacewalking sport hunters would kill mynocks by attaching helium - based grenades to them in what was called " Mynock Puffing " . They fed on electrical , stellar , and electromagnetic energy , and would thus attach themselves to power cables or ion ports on ships and structures . The energy was absorbed through a big sucker - like mouth located between their eye stalks . Some Mynocks had legs , while others were legless . In atmospheres , a mynock produced a loud , piercing screech . As they lacked any major organs , they reproduced by mitosis , but only after they had consumed enough material required for replication . A few ( sub ) species appeared to have existed , including one that had a normal mouth , rather than a sucker - like one , and another that had blue skin and gave birth to live young . They were commonly eaten by another silicon - based creature , the exogorth , and were the favorite prey of tailring s , who devoured them with voracious relish . Swarms of mynocks could be found alive , flying around a space slug ' s innards for an extended period of time before digestion began . While living in a slug , they could obtain sustenance by feeding on its veins and intestinal lining . Despite being a silicon - based lifeform , a properly prepared mynock could also be ingested by carbon - based life forms ; they were sometimes used in Twi ' lek cuisine , such as Mynock Coronet City . However , they were usually seen as a last resort meal by converting their flesh into bioplasma for space stations or colonists , albeit low quality and bitter tasting rations . Mynocks tended to flock together , generally in a pack of ten , however could migrate annually in large groups . The most notable of these migrations were the famed migrations of Roon , where the sky could literally become darkened from swarms of these creatures . They tended to protect territory in which they resided and would attack in larger numbers if they felt threatened . It is possible that they communicated using pheromones , telepathy , or even through a . Subspecies of mynocks included the salt mynock and sulfur mynock of Lok , the atmosphere - breathing Vynock that lived on Corellia , Talus and Bothawui , the Tatooine mynock , and the Talusian Fynock . Atmosphere - breathing mynocks also lived on Imdaar and were known to attack those piloting speeder bikes through the planet ' s swamps . A group of sentient mynock s , related to mynocks , evolved on a lone asteroid in the MZX32905 system near Bimmiel . Snow Mynock s were found on Hoth . History . During the Galactic Civil War some factions within the Rebel Alliance used mynocks as nuisance tactics against the Imperial space fleet . When the Imperial Security Bureau learned about hidden mynock incubation facilities , they sent agents to level the buildings . The Mynock in culture . Because mynocks were generally considered to be loathsome pests , the word " mynock " was used as a disparaging term . However , in recognition of the mynock ' s skill at evading attack , the Jedi Order named a form of lightsaber combat after the beast : Soresu . Cade Skywalker also had a starship called " Mynock " . Jacen Solo , Ben Skywalker , and Toval Seyah used the code name , Team Mynock , on their mission to infiltrate the Centerpoint Station . Mynocks were believed to have little charisma , and irritating people were sometimes compared to mynocks . Mynocks were spiced and eaten at some times by the Twi ' leks , in a way that was reportedly considered good - tasting by other species , although this seems unlikely unless these other species are also silicon based , given that silicon based and carbon based biochemistries are incompatible . Behind the scenes . Mynocks were first introduced in the .
