Since the fight between the Irken leader with a heart of gold and the scientist with a stubborn mind, the tension between them was harsh. So thick that you can cut it with a knife. It was so thick, that it made Dib's and Professor's fight seem like nothing, a speck on a wooden table basically. While their fight was a huge mud stain on the carpet, one that probably wouldn't come out, ever.

Every time [M/N] came over, he was either quiet around Professor Membrane or gave simple and small responses, sometimes he would even ignore the other. The first friend he had mad on this planet already hurt him, he wanted to dig a hole, bury himself and come back stronger but sadly, bills needed to be paid. The telephone one of course, he rather have that then be tracked by his PAK phone if necessary.

It been hard, losing a friend like that but he was right, [M/N] was there as an employee, nothing more or less. He wasn't Mateo's friend, he wasn't, they only hanged out as friends which [M/N] expected but he enjoyed it, a lot.

Now, its been a week since the whole incident, and [M/N] was currently packing two bags for an exciting adventure. Ms.Bitters class had been forced to take on a field trip, it was the class' turn now and everyone was excited, the kids at least. The Zoo they were visiting was out of city, into another one, three hours away. So the possibility of clean things and people, it sounded like a dream come true.

[M/N] was selected out of a machine to be a human chaperone for the children along with three other parents. He had watched tv shows about this kind of human children event,  and about Zoo's in general. His favorite part is when the penguins began to dance because of the much taller penguin started first with his tapping feet. He would hope to see another Mumbo.

" Dad? Are you done preparing us for this horrid, stupid, dookie, trip?" Zim asked, marching into the kitchen with his human disguise on, and looked over the two purple bags, one for him and one for [M/N]. " Why do we have to go anyway?"

" Well, your school-mates seemed to enjoy the idea and wouldn't it be nice to survey the other human amusements on this planet?" [M/N] asked, " It would be a nice way to understand humans and their fun."

" My mission is to destroy Urth and take over as their overlord, why would I care what they like?" Zim asked, his tone stiff and sharp. " What's wrong with our forms of fun?"

" I don't enjoy when they take different smeets with different physical effects to the training ward for target practice." [M/N] said, his tone cold and harsh. Not directly towards Zim, but to what the control brains decided to do with the poor smeets that were made differently. " Abusing smeets isn't something I find entertaining." Zim flinched a bit, he remembered most smeets with physical defects were taken off by many robot arms and onboard a small ship, most of them making noises and crying. A painful memory he had. [M/N] clapped his hands and took a deep breath, a calming one.

" We should head out soon, the darn yellow machine will be here any minute now." [M/N] cooed as he moved with the bags, it was an overnight trip which [M/N] found to be a lovely idea, being around human animals at night. 

" Do you think the Almighty Tallest are still doing that?" Zim asked, once he slide over the pink sweater over his head. It was a tiny bit big on him, and the sleeves almost hid his hands. His eyes watching outside as Gir walked from behind them, eating a taco and slurping an icee, making obnoxious sipping noises. " Since you aren't there to delay the ships taking the smeets on the other side of Irk?"

[M/N] stared out the window, and closed his eyes, " Of course, I'm not there to stop them. All I can hope is that some would run away or hide." He opens his eyes as he clicked the disguise on, his usual looks with his hair and eyes, but with a yellow hoodie on, white shirt under the hoodie with a light blue jean jack over the hoodie. Light color jeans with black boots for shoes, something hipster and young, it looked nice on him. " Come along, the yellow machine is here." [M/N] said as both walked out from the home and Gir locked the door behind them, with a loud high-pitched laugh.

Once they got on, Zim sat on a seat, arms crossed as [M/N] sat beside them, putting the bags down by their feet. The kids on the bus were loud and rowdy, some screaming or chatting loudly to their friends. One of the other parents was sitting in the back, looking anxious and nervous, she was biting her finger which bothered [M/N] a tiny bit. The guy up front, was too busy texting on his phone and dressed in a sleek suit, ignoring the kids. " Are they always so noisy?"

" Sadly." Zim replies as he glared out the window. The machine began driving down another street, [M/N] look out the window too, the sun was high still and the kids kept talking loudly and occasionally threw things around. They were weird warm babies.

The machine stopped and [M/N] heard the doors open, must've been the last pair of kids and looked only to frown quickly when he noticed the last chaperone was his boss, Mateo Membrane or to the public; Professor Membrane. He noticed the two younger Membranes behind him, making him smile. " Hello Gaz, Dib." He greeted before yelping as Zim poked his head out from their seat and glared.

Dib glared right back. " ZIMMMM!"

" DIBBBBB!"

" Now, Now, son, let's sit down before the bus resumes itself." Professor Membrane cuts in, as he leads his children to the sit across from [M/N] and Zim. " You two can play once we arrived at the Zoo." He added as Gaz sat by the window, Dib in the middle and Mateo at the end. " Nice to see you [M/N]. I haven't realize that you were picked to be a chaperone either! Usually, I'm busy with work at the lab but it's good to come out and enjoy field trips with my children."

" That's good, it's nice for you to be a father once in a while." [M/N] saw from the corner of his eye, Mateo flinching but barely. A little beam of pride lit up in him, then it died away when guilt ate at it. 

" Being a father is one of the best jobs, being a scientist is the other one and being a well respected vet is too." Mateo said with his usual upbeat voice. " Or gamers." Gaz added as she kept hitting buttons on her switch.

" Gamers too, and Paranormal Investigators." [M/N] added with a smug tone when Dib looked to him with a large smile on his lips then went back to glaring at Zim. Zim shoots it back, and a growl coming from the back of his throat. 

This was going to be a long day.

After a two hour drive towards another city, kids whining and complaining about getting off the bus while pushing down Zim every chance when he moved to go after or try to claw at Dib. [M/N] sighs happily once the bus opened up and everyone got outside, he takes a deep breath. " Fresh Air, so good."

" It's contaminated like everything on this dookie planet." Zim snipped as he moved back when other kids came out, arms crossed and pout clear on his face. " It smells worst over here."

" Of course, animals live at the Zoo, it would smell like them." [M/N] said as he held the bags, once everyone came out of the bus, the vehicle speed away. He turns ahead at the opening as a young lady, with blonde hair and brown eyes walked up to them. She seemed dazed and wore an outfit with Zoo on the chest pocket. She was just like the human-workers back in their own city.

" Welcome to the Zoo, I am your guide, E-Erin, and COME AND ENJOY OUR LOVELEY WORK." She screeched out the last part, like other humans did. Erin leads them inside the Zoo, and everyone awed at the sight around them as they walked in. Immdeaility the kids began pointing and cooing at the sight of the monkey's. [M/N] wrinkled his nose in disgust as the smell came close, and covered his mouth and nose with his palm as Zim did too.

" What's that mud stuff they're flinging around?" A girl asked from their group, Erin grins, " Monkey crap." Students seem more amazed than disgusted like the two Irken's.

" How unsanitary." [M/N] groans as he looked away as some landed on the window with a loud noise. Zim almost hurls but looks away, his eyes looking around for something else to watch. 

" It may to be unsanitary, but this is how monkey's cure their boredom." Professor Membrane spoke up, holding his hand up high with his pointer finger pointed upwards. " They are actually intelligent beings, smart enough to work with NASA or paint pictures."

" If there're so smart, why are they the ones stuck behind glass?" Zim asked, his tone smug and confident. [M/N] would scold Zim usually, but he was right? Why wouldn't the hairy human just break out the glass window? Stupid Monkey.

" Because my dear student, animals out here with us would kill us and eat us with their razor sharp teeth. The carnivorous ones would anyway." Professor Membrane added, his hand still kept his position.  " That's one of the greatest things about the Zoo, seeing animals closely without the trouble of possible death."

" What's the fun in that?" Zim asked but was ignored as Erin began showing them towards the monkey exhibit. " WHY CAN WE NOT FIGHT THE MONKEY'S!?"

" Because most of the species is extinct, gah, how stupid are you Zim~" Dib asked, and mocked a bit as he walked along with the group. " They're going extinct, just like how I'll extinct your stupid race."

" Ugh-Uh.." Zim stammered before huffing, " Yeah right, I'll take you serious when your head shrinks, Dib-thing." This time Dib sputters for a retort but [M/N] moved in between them, placing his hands on their shoulders.

" BOYS! you two may play and argue after listening about the monkeys and other hairy creatures."[M/N] cuts in and directed them towards the group. " Now please be g-"

" These monkeys, the Capuchin, are monkeys that are Omnivores." Professor Membrane said, gesturing to the monkey's from behind the glass. " They-" Erin coughs into her fist and glared at the Professor. 

" Sir, are you here to work for the Zoo?"

" Why, No-"

" Do you wear the Zoo name on your white dress thingy proudly?"

" This is actually a L-"

" No, no you don't, so shut up or go away."

Professor Membrane coughs into his fist and shifted a bit, " My apologizes." [M/N] rolled his eyes as he looked at the monkey's that seem to stare back at them. He could tell, Professor Membrane did want to say something, anything. And he knew, the guy wasn't sorry either.

" These Monkey's are boring like the others!" Zim pointed out, " This is boring!"

" For once, I'm with Zim, can we please move on?" Dib asked, tugging on [M/N]'s sleeve, " Please? Anything!" 

" Can we go see the snakes?" Gaz asked suddenly, " Or something better?" She went walking by [M/N]'s side as well, her Hazel eyes looking up to the adult with a raised eyebrow. Not begging like the other two morons.

" Fine, as long as we meet at the lodge here tonight then I don't see why not." [M/N] glanced at the tour guide who drone fake facts. Slowly with the three children, he began shuffling towards the snake habitat. He perked up hearing footsteps and glanced to see Professor Membrane walking behind them, " Why?"

" She won't let me talk and plus, those are my kids.." He pointed out bluntly. " I know we are not on good terms but for the children, could we at least be a bit civil and nice?" [M/N] thinks over it before sighing, if it was for the children then how could he say no? He wanted them to have a good day here, despite the smell of Dookie everywhere. " Friends?" He offered [M/N] his gloved hand.

" Friends but if you dare be mean to me, I will feed you to those darn cappuccino monkey's."

" Capuchin, but that seems fair."
