Zurg mutates Jo-Ad vegetables w/ Transdibulator. Team Lightyear goes to Jo-Ad to investigate the problem. Booster's childhood pal, Buster, was lured into helping Zurg w/ the promise of glory and power (he had been jealous of Booster getting to join Star Command while he was stuck back home on the farm).

Team Lightyear receives a call from Jo-Ad while in the early phase of an investigative mission (involving a series of thefts); Booster's family is letting Booster know that the bunzel harvest (the primary crop on Jo-Ad, which resembles eggplant) is due. When Booster claims that his duty to the Space Rangers supersedes his farming history, his Grandfather reminds him of the legendary ""Bunzel Fever"", that strikes down any native of Jo-Ad that isn't involved in the bunzel harvest. Booster dismisses the legend and eschews the harvest. When it turns out that the legend isn't a myth, Booster goes through a ""pon-far""-type thing, that is marked by him ""hulking out"" into a large, bellicose form that is determined to harvest bunzels, or anything bunzel-esque (...and since this transformation is also marked by him having spells of mistaking anything roughly ovoid for a bunzel, this gets fairly hazardous for anyone who is rotund and/or in a space ranger suit, XR, and Team Lightyear's ship

When Booster is kidnapped by the Raenoks, in order to conduct a prisoner trade for Varg (XR is sent to guard Varg, who quickly escapes and takes XR to Raenok), Buzz & Mira fly off to save him w/ a newly developed cloaking device that can render 42 and/or its crew invisible. While attempting to sneak into the Raenok prison, Mira and Buzz spot Booster's folks, who heard about their son's capture and decided to attempt to save him. This allows the invisible Mira & Buzz to get through the first line of defense, while the capture of the Munchauser's provides a distraction. When they're attempting to figure out how to get through the second line of defense, Becky and her father, the Sheriff from Roswell, arrive (having also heard the news of Booster's capture). The capture of the Roswelleans provides yet another distraction. Finally, the LGMs also decide to help, which almost allows for Mira & Buzz to free Booster (...and XR, and Booster's parents, and the Roswelleans...), but they end
