Blorch was one of the planets marked for conquest by the Irken Empire. Invader Larb was originally assigned to conquer this planet, but due to his height increase, it was instead assigned to Invader Skoodge, shortest of the official invaders. In an amazing turn of events, Skoodge not only completed his mission, but was also the first to do it. Blorch became the first planet conquered in Operation Impending Doom II, and was converted into a Parking Structure Planet. Before the planetary conversion, Blorch was inhabited by savage rat people. Blorch was also the planet Zim made GIR find when he first tested out GIR's new guidance chip
