Dib spillin poop

Dib spills Gaz's darkpoop.

The issue opens with Dib caught in the middle of a mystical conflict between two figures fighting over a bottle of Darkpoop flavor Poop Cola. Dib narrates the oddity of this, before flashing back to earlier in the evening, showing him traveling all over the city in search of the limited edition Darkpoop.

A further flashback reveals that the reason for this is because, when fighting with Gaz over the TV remote, Dib knocked over and spilled her own bottle of Darkpoop. Their father then states that, as this accident was Dib's fault, he owes it to Gaz to retrieve a replacement Darkpoop.

Gaz further states that Dib has to replace the soda or apologize for spilling it; as Dib refuses to accept blame for the accident, he sets out to find another Darkpoop. But every store he visits is sold out, having sold all their Poop stock to GIR (a cutaway revealing that this is because Zim is making him use it to clean fudge stains off the Voot Runner).

Poopy gir

All the darkpoop is sold out.

Eventually, Dib learns of a store called the Den of Convenience which may still have some Darkpoop. Traveling there, he searches through the various flavors of Poop before finally finding a Darkpoop and buying it. Before he can leave, however, he is attacked by a hooded figure called Nightnubs, who tries to take the Darkpoop from him, only to be attacked in turn by a man named Fizzmitz. The two fight, with Dib stuck in the middle, until Nightnubs manages to get ahold of the Darkpoop and escape.

Afterwards, Fizzmitz tries to convince Dib to walk away, but Dib points out his receipt, which proves he is the rightful owner of the Darkpoop. As such, Fizzmitz brings Dib along to the secret headquarters of the secret organization Poopwatch, of which he is a member. He reveals that Poop has been used by wizards for centuries, as drinking it allows for control of the fabric of reality, and Darkpoop can grant access to a dark dimension which could destroy the world.

Nightnubs takes the last darkpoop.

Dib is highly skeptical of all of this, finding it to be ridiculous. But his protests are cut off as Poopwatch's psychic seer, who was trying to track the Darkpoop, is overwhelmed by its power. As Dib touched the Darkpoop, it is believed he can more successfully track it, so he is recruited as a new psychic.

He is then made to drink every flavor of Poop, until the sugar rush sends him on a vision quest; he sees the past and future, and is able to learn Nightnubs plan - to summon a monstrous Poop Dawg known as Poopthulhu.

Dib also sees that Zim is the key to stopping this, much to his annoyance.
