Minimoose is a supporting character that would have made its official debut in the unfinished episode "Nubs of Doom". However, due to the cancellation of the series, it only appeared in "The Most Horrible X-mas Ever".


Minimoose was originally made to be the ultimate tool of destruction and a replacement sidekick, after Zim got tired of GIR constantly being distracted by Suck Munkeys. Instead, Zim created a floating stuffed animal that takes the form of a floating, purple, nose-less moose.

It works very similarly to Chibiusa's Luna-P toy in Sailor Moon R. While appearing to be a failed creation, Minimoose truly is a tool of doom, but Zim doesn't know how to use it. However, GIR did manage to accidentally activate its built-in weapons while playing with it.

Minimoose would have disguised himself as a tiny airplane in "Nubs of Doom", much like GIR's dog costume. This was the only real known consistent disguise he would have had, although in Issue 24 he was disguised as a bucket.


Minimoose's personality wasn't shown much and it's unknown whether it is somewhat diabolical and mischievous in nature, or innocent and carefree like GIR. In the script for the unfinished episode "Nubs of Doom", it was very obedient to his master and completed all his tasks.

This was because Zim was originally going to install an Obey-o-nator-2000X, the most unquestioningly obedient computer brain in the galaxy, but Zim wanted it to be even more unquestioningly obedient.

Zim also accepted a top-secret experimental Vortian doomsday device offered by Vortian Prisoner 777 and incorporated it into Minimoose's construction. Minimoose, unlike GIR, is not tempted and distracted by Suck Munkeys, which was more than enough obedience for Zim.

Role in Invader Zim

Minimoose was supposed to be a primary character, but due to the series' cancellation it never got to be one. For some odd reason he only communicates through squeaking but that doesn't seem to be an issue since the characters around it can understand its speech, although the audience cannot. Its original purpose was to replace GIR as Zim's companion, although due to its failure to live up to expectations, Zim keeps both GIR and Minimoose with him at his base.

Minimoose made his debut in "The Most Horrible X-Mas Ever", but Zim mentioned that he has had Minimoose with him "the entire time." This is a reference to the unfinished episode "Nubs of Doom", which was scheduled to air before the premiere aired. However, due to Invader Zim's cancellation, Nickelodeon only let the animation team finish one episode, and they sided with the Christmas special. This resulted in Minimoose being a mystery to the fans.

Minimoose's role in the comic series has been mostly limited to cameos, though in some issues it has a slightly larger role:

  • Near the end of the first issue, it distracts Dib long enough for Zim to escape in the Voot Runner, setting up the events of the following issue.
  • In Issue 3, it serves as Zim's mount during his scheme as the artist "Shminvader Shmim", carrying him around from place to place.
  • In Issue 24, for the first time ever it actually accompanies Zim and GIR off Earth to the black market planet Cyberflox and is left behind with GIR when Zim is abducted.
  • In Issue 25, Minimoose and GIR fly the Voot Cruiser to planet Dooq to rescue Zim from Fitzoo-Menga's clutches.
  • In Issue 27, Minimoose is first seen being used as a bowl for GIR's food. It later does a terrible job at causing a distraction in order to stop Xooxi from boring Zim further, and finally gasps in shock when Zim insults their "host."
  • In Issue 38, Minimoose serves as Zim's primary assistant in his latest plan while GIR is busy impersonating Dib.
  • In Issue 44, Zim uses Minimoose to fly around Meat Mountain as he carries out his newest plan, similarly to what happened in Issue 3, though in this case Minimoose was most likely used to protect Zim against coming in contact with meat.


Only four functions of Minimoose have been seen:

However, Minimoose contains many more deadly super weapons in "Nubs of Doom", giving the name to what would have been it’s debut episode. Minimoose is also capable of giving speeches, as shown when it introduced Santa Claus and the teleporter to the people of Earth, who cheered massively; either due to Santa's presence, or that Minimoose made a satisfactory speech.

Minimoose is also shown to be quite persuasive. In "Nubs of Doom", another speech was made by Minimoose to get the "Stop Piling Cows" protest group to leave the base. Also in issue 1 of the comic series, Minimoose was able to distract Dib with idle conversation long enough to allow Zim to launch into space.


Invader Zim (TV Series)

Invader Zim (Comics)


  • Like the SIR Units, Minimoose is genderless, but is identified by whatever gender pronouns its master dubs them.
    • It was confirmed by Jhonen Vasquez at San Diego comic-con during the Invader Zim: Enter the Florpus! panel that Minimoose's assigned gender is undetermined, and it could be either male or female.
  • Unsurprisingly, Minimoose has had more appearances in the comics than in the TV series but has yet to have an issue where he is central to the plot.
  • Unlike Zim or GIR who needs disguises to conceal their identities from the humans, Minimoose technically doesn't necessarily need one since the resembles an Earth creature and doesn't have to worry about keeping its abilities hidden since most people are oblivious.
  • In Issue 38, Zim at one point uses Minimoose like a cell phone or walkie talkie to communicate with GIR.
  • Minimoose's vocabulary consists of small squeaks, - pronounced "Nyah!" - which are done by series creator Jhonen Vasquez.
  • As shown in Issue 44, Professor Membrane seems to think that Minimoose is one of "nature's deformities", which would explain why no one questions why it's purple or can float and squeak.
