Poop Dawg is a metafictional character who made his first and only appearance as the representative/mascot of Poop Cola in Door to Door. His name parodies the real-life rapper Snoop Dogg and is also an homage to the Pepsi mascot Pepsiman. He is never seen without his costume on.
Poop Dawg was seen in Door to Door as a person in a dog costume, encouraging kids to fundraise in the hope of winning a nonexistent "mystery prize", which caught Zim's interest. Later in the episode, he appeared as a "Gangsta Spectre o' D'feat" to try and discourage Zim, who was suffering heat-induced hallucinations as a result of his fruitless attempts to win the mystery prize. Here, Poop Dawg appeared to be clad in a Grim Reaper-esque cloak, and surrounded by mist.
Poop Dawg's hallucinatory "spectre of d'feat" persona appeared later in the episode, looking into the window when Zim first used his hologram device to successfully get people to buy candy. At the end of the episode, he was seen again mocking Zim, following the revelation that there was no mystery prize.
- Poop Dawg is based around Pepsiman. Pepsiman was Pepsi's mascot in Japan in the 90s; appearing in several commercials, is playable in the Japanese Sega Saturn version of Fighting Vipers, and has his own PlayStation game, and his mission in life is to make sure that people are enjoying Pepsi products.
- Poop Dawg was voiced by Phil Lamarr
