Zim and Dib finally have their dream of parenthood, when Zim is requested as a Tallest, despite his famously short stature. Not long after he gave birth, Zim must be whisked away for his new duty of royalty, reluctantly leaving Dib and his new baby alone on Earth. It absolutely tore him to pieces, but he can't let the rest of the Irken society know.... he and his family would be killed. So, Dib must raise a child alone while Zim tends to his new Tallest needs.
