Zim and gir laughing together

Zim and GIR laughing at the concept of a race prone to germs

Zim and GIR watch the end of Intestines of War where the humans have discovered the Aliens' weakness; germs, and is using this new found knowledge to restore peace on Earth. As the film ends, Zim mockingly laughs along with GIR, both convinced that any race with a proneness to germs are inferior. Zim then goes down to his base, proceeding to try a demo pair of germ vision goggles. Though confident at first, Zim becomes a germaphobe seconds later. Now shaking in fear, he orders the full version from Callnowia.

Scared Zim

Zim now in fear of germs

Soon, Zim's package arrives at his doorstep. Clearly able to see the germs around him, he snivels over the amount of bacteria and gets his cleaning equipment while GIR returns to the base holding a muddy pig. The malfunctioning SIR goes elsewhere, and Zim begins to sanitize his home along with his computer. A while later, Zim inhales the scent of his germ free base, admiring his work. However, he spots a small germ crawling in the cracks of his kitchen, which he exterminates moments later.

Germs 3a

GIR trying to hug Zim

Before Zim can proclaim his so-called victory over the small pests, GIR arrives at the base and lets loose another army or germs upon his arrival. To make matters worse, GIR begins to roll around the living room, making Zim tell his henchman to stop. Believing Zim was simply in a grouchy mood, GIR walks forward to him and tries to hug him. Zim's first resort was to run outside, but has been proved useless and ran back inside to escape the massive amount of germs outside, only to have GIR successively fully hug him. To get GIR out of the way, Zim puts him back into his dog suit and ties him to a tree in his front yard. Suddenly, Zim remembers about his mission as an "Invader" Zim tries to clear his mind of his fear by calling the Tallest so he can report his current progress.

Did that scare you too

Red and Purple scared by Zim's behavior

Inside the The Massive, Red and Purple groan after hearing Zim's call and discuss they should have sent him somewhere much more dangerous before answering the transmission. Zim tries to tell his leaders that all is going well, but is distracted by the ever growing number of germs getting into his base until he begins to yell out that he will destroy all of the germs in his sight, laughing evilly before the connection goes dead. As the screen buzzes, Purple asks Red if he was scared by that as well, to which he nods.

Gimme all the meat

Zim demanding meat

Low on disinfectant, Zim goes outside and unties GIR from the tree so they can go and get more cleaning products. He sprays his robot to clean him and then both leave. By the time they reach the store, it is night time. GIR is the first to spot the store and tries to run over to its, but is repeatedly stopped by Zim, who is spraying the area in front of him. Annoyed, GIR grabs the can of disinfectant to get more out. Suddenly, he spots a MacMeaties restaurant and runs over to the building—along with the can. Zim follows his henchman into the fast food restaurant, and looks in horror at that filth-covered customers inside. Upon finding GIR, the Irken makes a surprising discovery; the burgers are completely free of germs. Zim is told why they serve germ-free meat by an employee, as well as what they are made of: Used napkins. Realizing he could use this as a way around his fear, Zim demands to have the restaurant's meat.

The next day, Zim arrives at school covered in meat and greets his fellow students enthusiastically as they stare.

Facts of Doom

Cultural References

Exploding alien

An alien allergic to germs.

  • When Zim watches the video in the beginning, the issue with germs being able to kill off and stop an alien invasion is a reference to H. G. Wells' novel The War of the Worlds, where the Martians are killed by simple bacteria. The alien ships in it also slightly resemble the Martian War Machines from the 1953 film version, and use the 1953 heat-ray sound effect for their lasers.
  • MacMeaties is a fairly obvious parody of both McDonald's and Burger King.
  • In the movie, when one of the scientists is discussing about evacuating people to a homebase and live on the stars, he could be referencing the Philip Wylie's & Edwin Balmer's novel When Worlds Collide, where humanity evacuates Earth and live somewhere else in space.
  • Zim wearing tissue boxes on his feet is a reference to the business tycoon Howard Hughes' extreme germophobia during his later life, in which he stayed reclusive in a darkened hotel room, naked and wearing tissue boxes on his feet to protect them from germs.
  • Callnowia looks an uncanny resemblance to the Death Star from Star Wars: Episode IV A New Hope.


  • Zim breaks the fourth wall by spraying the disinfectant spray at the screen to the viewer.
  • This episode marks the first time that Zim has mentioned his Squeedly-Spooch, the super-organ that members of the Irken race have. However, it isn't explained what it is until "Dark Harvest".
  • A game on Nickelodeon's official website, titled In-Sanitation, was based on this episode. It has since been removed.
  • The scientist seen in the movie is seen throughout the series, most notably in "Halloween Spectacular of Spooky Doom", in which he sentences Dib to a lifetime in the Crazy House For Boys.
  • This is also the second time Dib nor Gaz appear, the first time being "Walk of Doom".
  • This episode marks the second appearance of The Tallest, and the first appearance of their redesigns.
  • In this episode, Zim is shown with four fingers. But, in most other episodes, he's shown with only three fingers.
  • This episode is the fifth episode to use the squiggly Invader Zim font in the title instead of the official font.

Changes & Cuts

  • "NanoZIM" and "Germs" were originally supposed to air as a pair. However, "Dark Harvest" and "Bestest Friend" were deemed too twisted to be aired together, so the partners were switched.

Things You Might Have Missed

  • After the pig leaves Zim's house, a motorcycle sound can be heard.
  • The famous Wilhelm Scream is heard in the opening movie, when one of the alien spaceships destroys a car.
  • Jhonen Vasquez and Steve Ressel are sitting inside MacMeaties. They also have the script for "The Nightmare Begins" on the table, meaning they're possibly discussing about it as they are seen talking.
  • There was a poster in the MacMeaties restaurant that read "JUST SAY YES".
  • GIR's eye twitches when Zim sprays him, though GIR's eyes are covered by his dog costume.

Inconsistencies and Animation Errors

  • After the scene when Zim closes the door to get away from GIR, his PAK's colors were reversed.
Five sec demo

The five-second demo.

  • Zim's Computer said that he would have a free five-second demo, though the demo actually lasted almost twenty seconds.
