 Bloody GIR is an Easter Egg visible in several episodes of the  series. To see him, one would likely need a DVD player capable of  viewing screens frame by frame. The most visible instance of bloody  GIR is in the opening sequence of Mortos der Soulstealer. The image  is evident for at least two frames in the end of one of the pipes  that snakes out of Zims house. Bloody GIR has also been sighted in  Bad, Bad Rubber Piggy as the last pig goes through the "space time  object replacement device". He has also been seen in the voot  cruiser sequence in the opening of Plague of Babies. He is seen  looking in the window of the voot at the left hand corner of the  screen several times, some more noticeable than others. Bloody GIR  was born when Jhonen drew an image of GIR covered in blood. He  wanted to make an episode that featured bloody GIR but Nickelodean  would not allow it. He decided to slip the image into several  episodes without their knowledge.
