Invader Zim vs Star Butterfly

Zim arrives at Echo Creek

No POV:
All of the invader and Zim was among the crowd listening to what the Tallest has to say. "This is your standard issue information retrieval unit, also known as a SIR. It will assist you in gathering valuable knowledge during your mission." Purple says and Red adds "It's also a thermos!" Purple them picks up a SIR unit and says "Who wants this one?" Which a invader yells out "I do!" Which Purple throws it at him Which the invader yells "Ow! Thank you!" He yells "Everyone else, line up and take a robot!"  Red yells out as every invader lines up to get their own SIR unit.
Zim POV:
I was in line to get my very own SIR unit and I was next. "Finally! A robot slave of my own!" I Said as I reached out my hands to get my robot. "Um, eh, we have a top-secret model for you, Zim." The Red Tallest says as they start looking at something which they must be getting my robot ready for me. "I can't wait!" I thought as I saw the SIR robot in front of me which it just lies there and I was a bit confuse. "It looks kind of... not good." I told them trying to figure out why. "Yes! Well, that's what the enemy will think!" Purple says as Red nods in agreement and purple adds "Get it?" "I see! Very good! It even fooled me! I am honored to be trusted with such advanced technology!" I Said as I was happy that they trusted me with this special model and I saw the robot turning on and it's eyes glowed red and it runs up to me and it says. "GIR, reporting for duty!" "GIR? What does the 'g' stand for?" I asked him which his eyes turned blue and he says "I  don't know!" He then starts hitting his head repeatedly and saying "Wheeeeee hoo hoo hoo! Wheeeeeeee hoo hoo hoo!" "Um, is it supposed to be stupid?" I asked them. "It's not stupid. It's advanced!" He told me even though I still think that it is stupid but who am I to complain to the Almighty Tallest!
Time skip
Me and GIR were on my ship heading to the planet that the Tallest has told me to go and I will do everything that I can do to make them proud and show that I am the their top Invader. "Okay, GIR! Our mission starts now! Let us reign some doom down upon the filthy heads of our doomed enemies!" I told my Robot "I'm gonna sing the doom song now! Doom doom doom doo doom doom" He says repeatedly.
Six months later
It had been a month since we had left the Armada and GIR was still singing Doom repeatedly and I was just done. "GIR... Would you please stop singing?" I Asked him as I was about to attack him until I heard the computer say "Proximity warning: Planet ahead." I looked at the control panel and I saw the image of the planet which Said Earth. "GIR, we're here! We're finally here!" I told him which he gave a indication that he was not done singing. "Doom, doom, doom, the end! Ooh, what's that?" He asked me which I answered "Planet Earth! This must be the place. Okay, first we have to set up a base of operations." "Heehee." GIR giggled "Focus GIR! This is where your advanced information gathering skills come in handy!" I yelled as his eyes turn red and he salutes. "Yes my master!" He Said as his eyes turn back to blue and rushes to the window as we were flying through the clouds. "You have to observe what these... Earthenoids consider to be... normal. Then, based on your observations, we make our disguises... and our home." I told him as we flew past tons of buildings and I was looking for a place to build our base and I then saw a perfect spot. "Here! We build here!" I Said as the ship stops between two buildings and it lands. I then get off the ship and I looked around and I yelled "Ooh, that was easy! GIR! Get out here!" Which he jumps out and falls on his face. "Hurry GIR! What did you learn?" I Asked him which he gets up and says "I saw a squirrel." I was puzzled on where he is going with this. "It was doin' like this-" He says as he starts to imitate a squirrel. "Concentrate, GIR! It is time for disguises!" I told him. "I wanna be a mongoose." He says "Shhh! We have to be quiet!" I told him as he saluted and runs up to the ship and we were choosing what our disguise should be and after three tries we found out perfect disguise.
