Mission to Rugosa / Legends The mission to Rugosa was an operation that took place in 22 BBY during the Clone Wars . The Galactic Republic and the Jedi High Council sought to build a base in the Outer Rim Territories for further combat against the Confederacy of Independent Systems , and Grand Master Yoda was dispatched with a convoy of clone troopers to the coral moon of Rugosa to engage in diplomatic negotiations with Katuunko , the king of Toydaria . However , the Dark Acolyte Asajj Ventress arrived first to negotiate with Katuunko on behalf of the Confederacy and its Head of State , Count Dooku . The Republic convoy was ambushed by several Confederate frigates , but Yoda was able to land on the moon in an escape pod with three clones . Ventress posed a challenge for the Jedi : she would send her best battle droid forces to capture him , and if he defeated the droids , Toydaria would be given reason to ally with the Republic . Should Yoda fail , Toydaria would join the Confederacy . Yoda accepted the terms , and he and the clone shock troopers Lieutenant CC - 4477 , nicknamed " Thire , " Jek , and Rys separately fought the droids . The three clones defeated a squad of B1 battle droids , but Yoda arrived to rescue the clones from a group of oncoming B2 super battle droids . After escaping , the four took refuge in a cave , where the Jedi Master imparted his wisdom upon the clones to inspire their efforts . Yoda proceeded to defeat several Confederate droid squads and three Armored Assault Tanks single - handedly , and Ventress broke the terms of the competition , dispatching droideka reinforcements to eliminate the Jedi . Thire launched a rocket and caused an avalanche , however , crushing the droids . With the Confederacy ' s attempt at a treaty foiled , Dooku ordered his apprentice through a hololink to assassinate Katuunko . Yoda and the clones arrived in time to stop the assassination , and Ventress was forced to activate pre - planted explosives to cause a rockfall and escape . Yoda was able to stop the rubble , and Katuunko promised Toydaria ' s service to the Republic , before departing aboard an LAAT / i gunship with the Republic diplomatic forces . Prelude . In 22 BBY , as the Clone Wars continued to rage on across the galaxy , the Galactic Republic sought to establish a base in the Outer Rim Territories for further combat against the Confederacy of Independent Systems . Supreme Chancellor Palpatine contacted the neutral king of Toydaria , Katuunko , aboard his personal " Peregrine " - class star yacht , the " Thief ' s Eye " . A potentially important Republic ally in the war , Katuunko had witnessed the Republic ' s compassion for civilian refugees firsthand during previous negotiations with Republic representatives , and he had even gone so far as to secretly assist Republic relief efforts in the Battle of Ryloth . Because of this , Katuunko agreed to enter into discussion with the Republic . The Toydarian king requested for a Jedi to be sent , as he had always wanted to meet one ; because of this request , the neutral moon of Rugosa was chosen . The Republic asked Grand Master Yoda to serve as its ambassador in the diplomatic negotiations . Upon receipt of his mission , Yoda left the galactic capital of Coruscant with clone troopers Lieutenant CC - 4477 , Jek , and Rys . The Confederacy used the recently built listening post Skytop Station to intercept the messages between Katuunko and the Chancellor , however , and dispatched several " Munificent " - class frigates to lie in wait for the Republic convoy . The Confederacy intended to stop the Republic convoy from reaching Rugosa and prevent negotiations between Katuunko and the Republic from taking place , while the Dark Acolyte Asajj Ventress was sent to Rugosa to persuade Katuunko to join the Confederacy , under orders to use any means necessary to achieve her objective . The mission . Confederate ambush . Being the first to arrive on the moon aboard the " Thief ' s Eye " , Katuunko and his guards were surprised by the appearance of two B1 battle droids and Asajj Ventress , whom Katuunko did not recognize . The Dark Acolyte claimed to be an emissary for her Master and displayed a holoprojector , allowing communication to be made between the king and the Confederate Head of State , the Sith Lord Count Dooku . The count was aware of the Republic ' s desire to establish a base in Hutt - controlled space and proclaimed the inability of the Jedi Order to protect others , as the Jedi were unable to protect themselves . The Republic " Consular " - class frigate arrived above the moon , carrying Yoda and several clone troopers . The convoy hailed the Toydarian royal delegation but received no response . Two Confederate " Munificent " - class frigates then came out of hyperspace and began firing at the vessel . Clone Captain Zak was willing to abandon the mission in order to save Yoda by returning him to Coruscant . However , Yoda stated that his mission was on the moon ' s surface and that the convoy should flee while he took three clone troopers to Rugosa in an escape pod . To increase the chances of the maneuver ' s success , the convoy launched all of its escape pods . On the moon below , Dooku stated that the Separatist Droid Army could better protect Toydaria , outnumbering the Grand Army of the Republic 100 - to - one . However , Katuunko doubted this , having heard that a single Jedi was worth a hundred battle droids . Meanwhile , with all the pods launched , the Republic convoy left the system . The Confederate warships attempted to shoot down the escape pods but missed Yoda ' s pod . The trial . Katuunko watched the Republic ship flee through his rangefinder , and Ventress attempted to use the retreat to illustrate the Republic ' s weakness . Further away in the jungle , CC - 4477 — nicknamed " Thire " — managed to patch into the king ' s communication system , allowing Yoda to speak to Katuunko through a holotransmission . The king was pleased to see the Jedi Master , having previously believed that Dooku had frightened him away . Yoda became aware of Ventress ' presence , as the Dark Acolyte proposed a contest to demonstrate which side was superior in strength . Ventress planned to dispatch her forces from the T81 Division to capture Yoda , and if he defeated them , the Toydarians would join the Republic . If the droid forces defeated Yoda , however , the king should consider joining the Confederacy . Katuunko was opposed to such a contest , as he did not request a meeting with the Jedi Master to have him engage in a fight . Nevertheless , Yoda promised to reach the rendezvous point by nightfall , and Ventress agreed with the king ' s demands that the Jedi had to be given a fair fight . After returning to her base , Ventress contacted Dooku and stated that her forces were being deployed . As Supreme Leader of the Confederate delegation , she did not intend for Yoda to get his fair fight and dispatched the recently promoted 224 with the task of leading the droid forces , and the battle droids prepared to ambush the Republic ' s diplomatic squad . Led by 224 in his Armored Assault Tank , the main column of Confederate forces advanced into the jungle . Yoda and his men made their way to the rendezvous position on a different path , as the Jedi Master was certain that their enemies were already heading toward them . The droids began to go through the coral of the jungle , but the dense foliage prevented the tanks from advancing . Yoda and the clones split up , seeking to use their surroundings to their advantage . The clones engaged a squad of B1 battle droids from the south and managed to defeat them , but B2 super battle droids then came to attack the clones , and the three were forced to flee . Yoda , meanwhile , was able to defeat an entire squad of droids on his own without even using his lightsaber . CC - 4477 was hit by a rocket fired by a B2 - HA series super battle droid and was wounded in the leg . Yoda appeared and aided the clones , using the Force to turn around a battle droid and destroy the rest of the squad . Droidekas soon appeared , and the Republic forces fled . Yoda , clinging onto CC - 4477 ' s back , deflected the lasers at a nearby tall formation of land coral , causing the droids to be crushed , and the four escaped to a cave to rest . The clones learned that they were low on ammunition , but the Jedi Master imparted his wisdom on the clone troopers to further inspire their efforts . After hearing the sounds of the droids approaching in the distance , Yoda and the clones exited the cave . The Jedi and his men arrived on a ridge to observe the advancing droids below , which were passing through a narrow pathway . Yoda left the clones on the ridge and faced three tanks and a large number of droids alone . The Jedi Master destroyed all of them , along with 224 , leaving Katuunko amused and Ventress angry . However , Ventress did not give up easily ; the Dark Acolyte broke the terms of the competition and secretly sent several droidekas to deal with the Jedi Master . As Yoda destroyed the last Confederate tank , the droidekas arrived , and the Jedi Master began blocking their laser attacks . CC - 4477 launched the last of the rockets at an overhanging rock above the canyon , causing an avalanche to crush the droids . Yoda then led the clones to the rendezvous point , remarking that it was not polite to be late . Endgame . Katuunko was greatly amused by the droids ' defeat . Through a holotransmission , he informed Dooku that one Jedi was not worth a hundred battle droids , but rather a thousand , and stated that he would be joining the Republic . Dooku urged him to reconsider , but the Toydarian king refused to deal with those who went back on their promises , as Ventress had broken the terms of the competition . Seeing that his plan had failed , Dooku ordered Ventress to kill the king , believing that negotiations might go smoother with his successor . Katuunko ' s guards tried to stop the Dark Acolyte , but Ventress merely Force - pushed them aside , knocking them unconscious . As Ventress attacked Katuunko with her paired lightsabers , she found herself confronted by Yoda , having arrived in time to save the king . Yoda used the Force to stop the Dark Acolyte ' s death blow from being struck . As Ventress ' droid escorts were dispatched by the clones , Yoda disarmed Ventress herself , and after examining her lightsabers , the Jedi returned them to her , having proven they were useless against his telekinesis , while commenting that she still had much to learn . Ventress was outnumbered , and Yoda suggested that she surrender . In order to escape , Ventress detonated pre - planted explosives at the " Thief ' s Eye " and caused the hillside adjacent to the Republic forces to collapse . Yoda was forced to telekinetically stop the rocks from crushing all of them , and as he did so , Ventress seized the opportunity and fled to her ship . Dooku , watching the events unfold through the holoprojector , commented before taking his leave that it was a pity that he had not been there himself . With the Confederate threat over , Yoda was able to enter into negotiations with Katuunko . The king stated that discussions were unnecessary , however , as the Jedi had already proven his worth . Katuunko presented his ceremonial sword to Yoda and entrusted him with his planet ' s protection while pledging Toydaria ' s support to the Republic , declaring that it would be an honor to fight on their side . A Republic " Venator " - class Star Destroyer arrived in Rugosa ' s orbit , sending down an LAAT / i gunship to pick up the victors , now that their mission was complete . Aftermath . The " Thief ' s Eye " , which had been destroyed on Rugosa , was eventually repaired . As the war continued , Dooku proved to hold a grudge against Katuunko for his refusal to join the Separatists , and the Toydarian king became a target for abduction when Dooku sent his new Sith apprentice , Savage Opress , to kidnap him at the king ' s palace on Toydaria . By doing so , Dooku hoped to force Katuunko into allying with the Separatists . Behind the scenes . The mission was featured in the October 3 , 2008 premiere of the on Cartoon Network and appeared in " Ambush , " the first episode of the series ' . The events leading up to the mission appeared in the " " , which led into the episode . It later appeared in the young readers book " " . In September 2010 , nearly two years after " Ambush " was released , the episode " Supply Lines " of " The Clone Wars " television series ' was released as a prequel to " Ambush " and explained why King Katuunko had been so willing to enter into negotiations with the Republic on Rugosa . The entry for Clone Commander CC - 1010 , nicknamed " Fox , " in the December 2008 " The Complete Star Wars Encyclopedia " incorrectly stated that Fox participated in the mission to Rugosa . Some of Hasbro ' s 2009 incorrectly stated that Yoda ' s mission took place to the Toydaria system and on Toydaria itself . The 2011 non - canon ical video game " " features the mission in its depiction of " Ambush . " Besides being much more humorous and comical than the episode , the game slightly modifies the mission ' s storyline ; instead of splitting up at the beginning of the mission , Yoda and the clone troopers stay together and engage the battle droids as a group . The young readers ' book " " erroneously classified Yoda ' s three accompanying clone troopers during the mission as an " army " of troopers .
