Plot Summary

Dog brain 1

When Zim's headquarters are having security problems, Zim attempts to upgrade the security system and get the job over with. He decides to put GIR in charge of ensuring nothing goes wrong while he replaces the computer’s AI, but when GIR begins to try to retrieve his rubber moose, he inadvertently causes the house to shut down, along with himself.

However, Zim soon discovers that GIR's brain has been uploaded into the central hub of the house, putting him in complete control over all the systems in the base. Needless to say, GIR does not put this to good use. However, trouble really ensues when the robot develops a craving for tacos and burritos, causing him to detach his new "body" from the base, and, transforming the house into a giant quadrupedal form, proceeding to rampage through the city on his way to the Krazy Taco.

After many fruitless attempts to reason with GIR, Zim decides to use the robot's obsession to his advantage: after buying GIR's beloved tacos at the Krazy Taco, the Irken refuses to give them to GIR until the robot returns to the base. GIR quickly complies, leaving a swathe of destruction on his journey home. Once the house re-connects with the base, GIR finally agrees to have his mind restored to his old body, as he discovers that his house-form lacks a mouth - which is essential for eating tacos.

Facts of Doom

Cultural References


Dog brain 2
  • This is the second episode where GIR has a prominent role. The first is "Walk of Doom" and the third and last is "GIR Goes Crazy and Stuff".
  • Zim originally told the elevator he wanted to go to the storage level, but for the rest of the episode he says the equipment room.
  • Officer Prambly (who debuted in "Walk of Doom") shows up again right after GIR sets the gas truck on fire, and he repeats his line from the other episode ("Get him!").
  • The police officer who says "Must be one of them new ones!" is the same officer from "Megadoomer". He is voiced by Kevin Hamilton McDonald, the voice of Almighty Tallest Purple and both characters sound somewhat identical.
  • The events of this episode has the second-longest time span in the series itself, because it takes place an entire year. Although, this might've been an exaggeration for comedic purposes. The longest time span in an episode was "The Most Horrible X-Mas Ever" where Mr. Sludgey tells kids two million years in the future about the worst Christmas ever.
  • This episode is the fourth where Dib and Gaz don't play a role, as well as the fifth time when Gaz isn't physically seen.
  • The scene in which a man sees how GIR crushes his new green car is based on a real experience of Rosearik Rikki Simons, GIR's voice actor. During the development of Invader Zim, Simmons bought an expensive green car, so Jhonen Vasquez and the crew found amusing to destroy it in the episode.[1]

Changes and Cuts

  • From what someone said during the episode commentary, when GIR says "Argh, where's my mouth?!", he was originally supposed to say something along the lines of "The pain, the pain".

Things You Might Have Missed

  • In this episode the Krazy Taco worker that Zim pays sees Zim without his disguise on, and does not react in a shocked manner.
  • The phone booth that a happy guy used had the word "OBEY" written in graffiti on it.
  • When GIR unleashes a host of floating video screens to overwhelm Zim, they're playing scenes from various early animated shorts. These same scenes appeared on screens during the reprogramming of the Roboparents in the episode "Parent Teacher Night".

Inconsistencies and Animation Errors

  • When Zim contacts the Tallest at the end of the episode, his PAK colors are reversed.
