" Zim! Stop!" [M/N] hissed as he smacked Zim's hands away from the tiny cakes he had bought from the store this morning. He had to fight three old ladies for it and he was sure one was at the hospital at the moment. " These cakes are for our guest!"

" ZIM HAS NO INTREST IN YOUR GUEST!" Zim huffed, his arms crossed over his chest. He was wearing his usual Irken uniform but [M/N] had managed to shove the Irken into a sweater for the occasion. It took three hours and lots screaming. " Why must we let humans into the base? Dib will only try to get into the lab!" Zim glared at the cakes as [M/N] walked passed him with them, he watched as the tallest placed them in the fridge. " You will compromise the mission."

" Oh come on, stop being so serious Zim." [M/N] said as he heard the kettle hiss, using a oven mit, [M/N] picked the kettle and placed on the counter. " Live a little, plus maybe you'll learn more about Christmas or earthly customs."

" ZIM NEEDS NO EARTH CONDOMS!" Zim huffed as he itched his wrist, the dumb sweater was ichy. He moved into the living room and glared at the tree that stood in the corner of his base living room. It was an ugly horrible thing, it smelled funny and looked funny too. The tree had purple tensile wrapped around itself, white and yellow little ball ordainments hanged at the end of branches and then the little ugly looking angel on the top. The tree was hideous. Huffing the Invader sits on the couch, his eyes glaring at the tv.

How can his tallest celebrate this human holiday? It was only about giving presents and being greedy to when it came about the gifts you receive. What a mockery, only tall people should be given gifts anyway.

" Zim, can you please open the door? It's been ringing for a couple a minutes." Zim grunts, he must've daydreamed. Getting up, he opens the door and immediately locked eyes with the human-stink. A growl came from the back of his throat as he spat out, " Dib-stink."

" Space-boy." Dib spat before groaning as Gaz punched him, at the back of his head. " What was that for?"

" Because you were being annoying." She huffed as she entered the home, their father following behind her. " Don't make yourself a target today, this is our first holiday out of our house." She hissed before walking to the couch and sits down, her squinted eyes back on the gameslave. Mateo comes in with an armful of gifts, he hummed as he sets them under the tree before looking up. The house was different from his, there wasn't much furniture around but had a purple couch and a purple recliner. A chirstmas tree in the corner with cute decore around it.

" Hello, Mateo." [M/N] greeted, he was now in his human disguise. His hair pulled back a bit by nice human gel, white button shirt and another equally ugly santa sweater on top, dark jeans and dark shoes to match. He had a sliver plate filled with many cookies on it, all in different shapes and different colors. Most of them were white, green, red and some had black to fill in Santa shoes and his buttons. He sets the plate on the small table that came up as he began putting the plate down, " Enjoy." Gaz reached over and picked up a Santa head, hitting the head off it. " That's my girl." Mateo praised.

" You like it when Gaz bites the head off Santa?" [M/N] questioned with a tilt of his head. Mateo hummed, " Why Of course, my daughter shares my dislike when it comes to Santa. Santa, that filthy money gobbler." Mateo cursed as [M/N] tilts his head still a bit confused. Well if that is what he likes to think then so be it.

" I just thought the head was tasty." Gaz said as she ate, Zim rolled his eyes. He picks a cookie off the plate and began biting it aggressively as he glared at Dib who seemed to be amazed about his base, of course he would, it was Zim's and [M/N]'s base after all. " The longer you stare at him won't make him blow up." Gaz snorts.

" Pft. I'll liquified his organs, it's a bit more neater then blowing him up." Zim hissed as he began chewing on the rest of the cookie. He licked his lips as he grabbed another one, " Howdy y'all!" Gir squeaks as he comes out the kitchen wearing a Santa skirt with bells on it with a matching hat.

" Is your dog talking?" Mateo asked as [M/N] giggles in a nervous manner before tugging on the others arm. " No, but come, I am almost done with the tamales." [M/N] said as Mateo follows him into the kitchen, " I knew this was part of your tradition and I enjoy the store that I went to retrieve them from." On the small kitchen table was 13 white boxes filled with every tamale he could possible order. " Zim helped me carried them here, though he complained about the smell."

" I see.." Mateo stared at the boxes, and walked over to the boxes. [M/N] stood next to him, eyes wide and he played with his hands nervously. Did he do good? Did he get the wrong food? Mateo opens the first white box and three clean and warm tamales laid in the box, mist came up hitting against the scientist goggles. " Are they what you wanted?" [M/N] asked.

" Yes! And they're still hot, ready for consumption." Mateo said as he turns towards the babysitter who grins, pride swelling within his chest. " You didn't have to get them, just so you know, I mean.." God his mouth felt like jelly and stiff at the same time when he talked to [M/N]. He had told the baby-sitter some older traditions that he did as a child. Staying up until midnight to open presents, making tamales with his family though it was only the women, watch his dad and uncle play cards and drink beer or eggnog, then they fall asleep after opening presents. " I really appreciate the food, perhaps next year we could make them together...with the kids of course.." Mateo tugged at his cowl, feeling nervous that he even asked.

" I would enjoy that." [M/N] smiles as he looked at the food, " Though, I wouldn't want to make the kids wait too long for the presents. I want to see their expressions when they open their gifts from me."

" I can agree, they need their eight hours of sleep." Mateo placed the white box down and rubbed his gloved hands together. " Though, Gaz can live on four hours of sleep, very impressive."

" That's not good Mateo." [M/N] said before hearing a crash, the taller Irken looked into the living room with Mateo who watched too with mere curiosity.

GIR was screaming and running around with a mistole hanging from his ears, Dib and Zim were fighting and rolling around on the metal floor. Dib was choking Zim and Zim was hissing and kicking Dib in the gut repeatedly. Cookies were on the ground and being crushed as the boys rolled over, Gaz was still sitting and playing her game like the good girl she was. Plus she didn't want to clean their mess if she got involved.

" YOU SPACE FREAK!"

" YOU BIGHEAD FROG!"

   Both boys hissed as they fought, [M/N] sighs before walking into the living room but Mateo was quicker, he pulled both boys away from each other. Zim hissed in the grasp, swinging his arms and legs wildly. Dib lays limply in his fathers grasp as they were sat on the couch, Gaz was in between them.

" Now boys, today isn't about fighting." Mateo said as he looked at the two, " today is about Christmas and gift giving, our first holiday together too. Now, I know you two like to play but play in a modest way. Dib, my boy child, please don't wreck things while we're here in [M/N]s and Zims House. Please try to be respectful." Dib sighs nodding, " I'm sorry [M/N]." Dib said in a quiet voice.

" And Zim, I'm sure your father worked hard to make this cookies and decorate, I'm sure your boys will be boys play time can wait until after the holiday." Zim huffed, arms crossed, " Plus I'm sure he got you that movie you've been eyeing~" Mateo hinted and Zim flinched and looked to the scientist with wide eyes. " You've been good, the both of you. Keep up the good behavior and we might open presents early." Both boys glared at each other before sighing.

" truce until after Christmas?"
" Truce for now, stink-Dib."

[M/N] smiles, walking over. " Thank you for handling that, I would've let them off with a slap on the wrist." Mateo turn to him, smiling, " No problem, I learn from the best of handling these situations with my own kids." [M/N] smiles, his disguise heating up around his face. Cheeks pink and eyes drifted away for a second. He only looked back to Mateo when he saw him falling-

Wait falling?!

[M/N] gasped, grasping the scientist by his shoulders but Mateo was much heavier than the Irken leader so he crumbled a bit and eyes widen as his lips touched something soft. [M/N] looked down to his lips, seeing he halfway pulled mateos collar when he caught him. His eyes wide as mateos too, it wasn't really a kiss but their lips were pressed together tightly.

" Ewwwee! Oh disgusting!" Zim exclaimed and covered his face with his hands. Gir was giggling, " I did it! I got grandpa a boyyyyyyyfreedeeeeinnnnndddd!" He screeched as he jumped off mateos back. " now eat the mistletoe!" A green plant smacked against [M/N] face which made the tall Irken drop the human.

" Oh my..." [M/N] covered his mouth, eyes wide and giggling. He didn't look at Mateo who laid on the floor, Gaz and Dib was around their father, Gaz kicking him lightly.

" Oh my....." Mateo wheezed, " Are you and [M/N] getting married now?" Gaz asked, her game paused as she unsquinted her eye to look at their father. " Is He our new dad?" Dib asked in a teasing tone.

" Kids stop, you're gonna give me a heart attack if you ask questions like that."

Zim kept his face covered but turns to [M/N] who kept giggling, " Does Zim and the Dib-thing have to fight to the death for the title of son? Zim will destroy him if he must!"
