Here's the second future head canon, enjoy!
The sun peaked over the hills of Canada, shining brightly and greeting everyone with its warmth... Sort of, it was freezing thanks to the snow everywhere. Marco pulled back the curtains in his room and breath in the air that flowed through his open window, the sight was beautiful. Small tufts of frozen rain were strewn about the hills and fields are of the small valley he lived in, finally being able to escape from his apartment back Manhattan.
After taking in the glorious view, Marco walked over to his drawers and pulled out some cloths, being careful not to wake his sleeping wife.
Marco, now fully dressed in a red lumberjack style shirt and Blue jeans that draped just over his ankles, walked into the dining room and poured himself a cup of black coffee. As he took small sips of the warm, bitter liquid, he heard small squeals from down the hall. He smiled and then rolled his eyes as the squealing was followed by a loud explosion from the hall.
"Marco! Would you go tell the kids to calm down! It's only 9 pm, for Mewni!" Star yelled in annoyance. Marco chuckled and put down his mug, he walked down the hall and peeked into the second door on the right. Inside the room were two small children, one was a girl his dirty blonde hair and emerald green eyes, she looked about eight years old. The other was a boy with shaggy brown hair and sky blue eyes, a couple years younger than the girl.
The two sat in a deep crater and seemed to be fighting over an object in the boys hands, "Give it back!" the girl yelled as she tugged at he boys hair. The boy held the object back and pushed away the girl with his free-hand.
"No! It's mine!" he screamed, the battle between the two raged on for a few minutes, that is, until Marco cleared his throat. The two children immediately stooped fighting and looked directly at their father with wide eyes.
"Actually" Marco smugly said as he walked over and took the object from the boys hands, "This belongs to your mother." The object transformed in Marcos hands, it turning a light shade of purple with ribbons and wings attached to the handle of the wand, its head reverting back to its normal form. The children lowered their heads in shame and Marco grabbed them into a headlock, the kids squealed with laughter as they were thrown about the room in their dads loving arms. They continued to wrestle each other until a small laugh erupted from the doorway. Marco and his kids looked up to see the alpha dog of the family, smirking and giggling at the three's antics.
Marco dropped the two kids and pointed at them in accusation, "It was all them! They dragged me into a war and had to fight back!" he yelled, Star just smirked even wider and walked down next to her husband in the giant crater. She grabbed her wand from his hand and kissed his cheek, he lightly blushed and scratched the back if his head.
"I told you we shouldn't have taken it!" the girl scolded her sibling, the boy just scolded her right back with, "You're the one who dragged me out of bed for the stupid thing!" The two pushed their foreheads together in anger, lightning crackling from their hands.
Marco walked over and separated the two before another fight could break out, Star looked over her children and spoke in an authorized tone, "Ruby! James! As punishment for your crimes against the sanctity of my kingdom, your punishment is to go play video games in the living room!" Ruby and James looked at their mother in confusion, as did Marco, until she finished her sentence.
"But the only game you can play will be… SONIC 06!" She yelled, standing on the tips of her toes and pointing to the sky with her wand. Ruby groaned in annoyance and walked with James to the living room, once they were gone, Marco walked over to his wife and slipped an arm over her shoulder.
"Well, that was quite the wake up call!" he exclaimed and looked at Star with bright eyes, he leaned in an tried to kiss her but she quickly sidestepped out of the way and he fell forward into the dirt.
Star crouched next to him and poked his side, "You're in trouble too hot stuff! So you can go play with them." Marco groaned into the dirt and mumbled something incomprehensible. Star just smirked and walked away smiling.
Today was going to be a long day.
