Senni Tonnika / Legends Senni Tonnika was a Kiffar female and identical twin of Brea Tonnika . The two were known as the Tonnika sisters and became infamous con artists under the New Order . In 0 BBY , they earned additional fame for being in the Mos Eisley Cantina when Luke Skywalker first met Han Solo , but in fact , the " Tonnika sisters " in the Cantina were the Mistryl Shadow Guard warriors Shada D ' ukal and Karoly D ' ulin , masquerading as Brea and Senni in the course of a mission . Biography . The best - known source of information on the Tonnika sisters is a biographical entry written by Rebel Alliance historian Voren Na ' al . However , his account contains a number of inadvertent inaccuracies , and it is unclear how far it can be trusted . Early years . According to Na ' al ' s account , the sisters were near - Human " Kiffu " who grew up on the colony of Kiffex ; although " abandoned " by their parents in early childhood , they were raised by the colonists in safety and with affection , but they were led astray through a desire for money which their homeworld could not offer . When a young scout pilot arrived on Kiffex to take on provisions , the teenage twins persuaded him to take them offworld with them , claiming falsely that they had been maltreated by the colonists . Several problems with this version of events must be noted straight away . Kiffu is not the name of a species , but of a planet , the homeworld of the near - Human Kiffar ; the settlement on Kiffex was a notorious prison colony , an infamous den of lawlessness and depravity strictly interdicted by the local security forces . It can be inferred that the sisters grew up on Kiffex , and escaped in their teens through the help of a scout pilot who had landed at the colony ; it may even be true that they were treated with relative affection and compassion by the criminals among whom they spent their formative years ; but the entire timbre of the standard account must be treated with caution . Career as con - artists . Over the following years , the Tonnika sisters acquired a reputation among the galaxy ' s leading con artist s , running several notorious scams against high - society targets , ranging from crimelords to members of the Galactic Empire ' s new elite . On one occasion , they conned Grand Moff Argon out of twenty - five thousand credits , and in 0 BBY , just before the Battle of Yavin , they were on Tatooine to attend a party thrown by Jabba Desilijic Tiure at his palace on the edge of the Dune Sea . In this much , at least , Na ' al ' s account would appear to be broadly accurate . However , Na ' al was incorrect in his claim that the twins were arrested in Chalmun ' s Spaceport Cantina in Mos Eisley , a few hours before Alderaan was destroyed . Although he later acknowledged this mistake , he remained ignorant of the true identities of the women who had been in the cantina : the Mistryl Shadow Guard warriors Shada D ' ukal and Karoly D ' ulin . Masquerading as the sisters , they were arrested by Imperial Colonel Parq , who was hunting the real twins , but subsequently released by Rebel agent Riij Winward . The Tonnika sisters themselves eluded capture , despite the efforts of Argon ' s agents , and continued to operate as con artists . The true identities of the Mistryl " Tonnika sisters " were not disclosed in Winward ' s report to the Rebellion , and would go unrevealed to Rebel / New Republic personnel until D ' ukal petitioned Leia Organa Solo to join the New Republic during the Caamas Document crisis . Identical twins . Many of the stories told about the Tonnika sisters turn on the difficulty of telling them apart . They often masqueraded as a single woman named Bresenni , and Vul Tazaene , a Kiffar security officer searching for them , was in love with one of them , but did not know which . One of the best - known — and perhaps most reputable — stories about the sisters involves Han Solo , and a scam on Lando Calrissian . Solo had come to know the sisters through his dealings with Jabba Desilijic Tiure , and persuaded them to help him play a trick on the smooth - talking scoundrel . Solo arranged for Calrissian to meet " Bresenni " in The High Stakes Casino on the planet Balfron , and although Calrissian thought that his new " girlfriend " suffered from severe personality shifts as the sisters swapped around in the role , he genuinely believed that he was growing close to her when Brea and Senni revealed the deception . As he watched a holo - message from Han , Calrissian was at first dejected and angry , but quickly softened , although he vowed to get even with Solo for the stunt . Behind the scenes . In " " , two tall girls appear together in the Cantina scene , wearing matching catsuits , and with braided hair piled high on their heads . Played by real - life friends Christine Hewett and Angela Staines , they were known by the simple production nickname " Space Girls " Christine Hewitt has since been identified as portraying Shada D ' ukal , disguised as Brea Tonnika with Angela Staines portraying Karoly D ' ulin , disguised as Senni Tonnika in 1977 ' s . It is sometimes thought by fans that the girl who kisses Han in the ANH rough - cut is one of the Tonnika sisters . In fact , this " Cantina Girl " is a different character known only as Jenny , played by actress Jenny Cresswell . In " " , these characters were identified as the interplanetary con - artistes Brea and Senni Tonnika , but the article insisted that the sisters were identical twins , both 1 . 6 meters tall , while the characters seen on screen were visibly different in height and appearance . Hence , Timothy Zahn ' s short story " " established a retcon that identified the girls in the Mos Eisley Cantina as Shada D ' ukal and Karoly D ' ulin , disguised as the Tonnika sisters . This retcon was possible due to the original " Galaxy Guide " material being presented from an in - universe perspective , as the work of Voren Na ' al . Subsequently , however , the " Galaxy Guide " version of events has been further undermined by the depiction of Kiffex in the " " comics , particularly in the " " storyline , which is largely set on the prison - world .
