" Plot summary . Padmé , Jar Jar and Threepio arrive on Naboo and are greeted by Queen Neeyutnee and Captain Typho . The Queen demands that she petition the Senate or the Jedi High Council to assist them ; Padmé says that a scout team of droids is not enough proof , which is why they must analyze the tactical droid caught from the scouting party . After taking out the droid ' s eyes , they trick it into thinking it is with the Separatists and have it report . All the droid can tell is a top secret lab on Naboo before being crushed by Jar Jar ' s bumbling when the latter tries to catch a blue bug emerging from one of the battle droid ' s bodies . It is found the bug could have only come from the Eastern swamps , in whose mud the tactical droid is covered . They contact Master Yoda and Master Mace Windu and ask them to send two Jedi : Obi - Wan Kenobi and Anakin Skywalker . Padmé and Jar Jar then opt to personally search for this secret lab while the others extract as much information from the other droids . Out in the plains , a female Gungan shaak herder named Peppi Bow notices that a few of her shaaks start to collapse dead , so she ushers her herd away , realizing that the river they drank from is tainted . Soon after , Padmé and Jar Jar arrive , but they are attacked by Peppi until Padmé brings up her blaster . Peppi directs them to follow the river to find the source and offers to guide them , but Padmé declines , instead sending for an escort back to Theed . As they traverse the swamp , they are being spied on by a camera . Then they find a secret hatch , but there is no way to open it . Suddenly , they are surrounded by battle droids , taken prisoner and placed into the bunker . The man in charge , Dr . Nuvo Vindi , reveals that he has recreated the Blue Shadow Virus , a deadly disease that was wiped out from the galaxy long ago . He had also perfected it , able to turn it from a liquid strain into an airborne strain , which would be used to eradicate the warmongers . Upon arriving on Naboo , Anakin , Ahsoka and Obi - Wan learn of Padmé and Jar Jar ' s departure . Anakin sends Ahsoka with Peppi to find them , while the rest of them analyze the data from one of the lobotomized droids . They find out that Vindi is planning on deploying virus bombs to key star systems . Typho directs them to Vindi ' s secret lab , which has three entrances . Anakin fears the risk of contamination , but Obi - Wan states that one planet is less than the entire galaxy . Ahsoka and Peppi search the swamp , inadvertently find a spy cam and manage to hide from it . Ahsoka contacts Anakin and Obi - Wan , who instructs her to detonate a bomb in the south bunker while they enter through the hatches . Anakin then joins with Rex and his men to start the mission ; Obi - Wan reminds him that the safety of the galaxy is worth more than Padmé ' s life and she may already be dead . Ahsoka levitates a thermal detonator , perfectly dropping it on the hatch and distracting many of the droids to her position ; Rex and his team also arrive to assist her as they hack their way through droids before having to retreat with the entrance of droideka s . This allows the others to infiltrate the base unheard . But as Anakin enters Vindi ' s lab , he finds Vindi torturing his hostages with electricity , forcing him and his clones to surrender . As Vindi leaves Padmé and Jar Jar to suffer , he runs off with his virus bomb ; Anakin breaks free and saves them . Obi - Wan arrives with the Bomb Squad . Unfortunately , as Obi - Wan and the bomb squad finds all the bombs , Vindi activates them . With Vindi and another droid each carrying a detonator , they split up between the two . Obi - Wan tries to catch Vindi , but the villain throws away a number of virus vials , forcing Obi - Wan to catch them while Vindi makes his escape . Meanwhile , Padmé and Jar Jar track down the droid , managing to prevent it from escaping . With the bomb squad ' s help , they are able to deactivate all the bombs , just as they capture Vindi . Behind the scenes . In the script , the tactical droid was originally a medical droid . This is why C - 3PO says to it , " We all want to hear your tale of medical heroics . " Originally in the script , after Vindi ' s servant droid LEP - 86C8 took the bomb , it left , never to be seen again . Padmé found the missing bomb in the greenhouse room , hidden for no apparent reason . The addition of the scampering droid with the bomb was made not only for story logic , but to add the humor when it startles Padmé .
