While Cody reminds the " shinies " — the younger and inexperienced clones who are manning the station — the importance of their duty , Rex notes that the station looks unusually clean . One of the clone troopers , Stripe , explains that an MSE - series droid that had been nicknamed " Rodent " by the clones spends a significant amount of time polishing the station , which Stripe believes to be the result of a glitch in the droid ' s programming . The inspecting officers immediately see the droid ' s action as suspicious and issue an alert Code Aurek on the station . Rex orders the clone troopers to search the station and find the droid by whatever means necessary . During the search , a clone trooper nicknamed " Bouncer " asks Stripe for his opinion about the alert , wondering whether the officers conduct the same drill at every inspection . Stripe , however , realizes the danger of a potential spy within the base and abruptly tells Bouncer not to ask stupid questions . When the droid is spotted by one of the clones , Rex immediately points his blaster at it , preparing to shoot . Seeing that his position as a spy is revealed , Rodent tries to escape , but Rex chases the droid and destroys it with a blaster shot . However , the droid ' s wheels are revealed to be individual droids of their own , and they try to escape by splitting up . One " wheel " is smashed by a clone trooper with his helmet , another one is shot down with a blaster , and a third is disabled when electrical energy from a loose wire is directed at it . When looking for the fourth wheel droid , Stripe notices that it is heading toward a grate . He realizes that if it gets through , it would be impossible to find again . Determined to stop the spy , Stripe throws a V - 1 thermal detonator at the grate , which destroys both the droid and a solid portion of the station ' s interior . When Rex asks Stripe if such a radical solution was necessary , Stripe proudly responds that as a clone , he never leaves anything half - done .
