Invader Zim: Enter the Florpus

When Zim and GIR suddenly reappear on their lawn after years of absence, an obese Dib Membrane, who had been awaiting their return, confronts them. Zim reveals that his disappearance was part of a plan to make Dib physically unfit to oppose him, allowing Zim to begin Phase 2 of invading Earth. Zim contacts the Almighty Tallest to explain Phase 2 to them, but realizes he has forgotten what Phase 2 entails due to having been in hiding for so long.
