S1·E10 Junk in the Trunk

Coop accidentally damages a vital part of Megas, the photonic stabilizer. Without it, Megas will go up in a blaze of fiery glory and explode, which will not only destroy Megas, but also, everything within a 100-mile radius. Fortunately, Coop found a junk planet that probably has just about everything. Unfortunately, Varshin the Dealer wants Megas' time drive to complete his own robot and sends various "zombie" robots to retrieve it. Even more unfortunate, Goat has come along for the ride, and is thoroughly annoying Kiva, not to mention he's fantasizing about a personal robot of his own without any idea how to get or build one properly.
