Invader Zim #29

Plot

The city is a dark place… as dark as new Darkpoop Cola, an exclusive Poop Cola flavor available for a limited time! When Gaz demands her brother get her some of the precious cola in the middle of the night, Dib enters a shadowy underground of Poop-driven factions warring for control of all Poop-kind. But why? Is there more to Poop than meets the eye? And is it all just too stupid for Dib to care about? Part one of a two-part story.
