Well after doing some experimenting, 9t seems I've managed to create a very, very, vey, very niche little drabble-y fic, to say the least. Not only is it a Gravity Falls and Star Vs. the Forces of Evil crossover, the Gravity Falls part of it comes from the Future-Pines AU I've developed and written overly-extensively about (if you're not familiar with it, just go to my profile and prepare to be inundated.)

For the (possibly very, very, very small) cross-section of my usual readers that watch and like both shows, I hope you enjoy this oddity I cooked up! It's only one little story for now, but we'll wait and see if I can cook up anything similar later on down the road! - SGA

"...Okay, so….uh….."

"Are you alright?"

"Yeah, yeah, it's just….wait, so….okay, I'm sorry, but let me get this all straight one just more time." The teen politely asked as tried to wrap his head around the situation. "You watched us fall into your world, then were told that we got here with dimensional scissors and that one of us is a magical princess from another world that's separate from the one that I'm from, and….you're honestly just fine with that? Seriously, no big deal at all?"

The near-identical young man and woman both nodded jointly in casual affirmation before the latter erupted with bubbly giggles.

"We said it twice before already! So why would it be a big weird deal the third time you asked?" She laughed. "Silly!"

"I mean, this definitely a first for us," Admitted the young man, who was quick to clarify "But just with the specifics, and not so much what's happened in general. This actually isn't the first time that we've seen someone come out of another dimension." .

"And not the weirdest thing we've seen ever!" Added his sister. "If anything, you two are low, low, looooow on that list!"

"See, Marco?" The teen's friend and dimensional travelmate smirked triumphantly from not too far away. "Told you they meant it the first time they said it! They're totally okay with us! Isn't that right Mar….uuuhhh, wait, no, hold on, don't tell me, don't tell me, iiiiit's…..Mabel?"

"Yes indeedy!" Mabel Pines gestured back. "And you're….Star, right?"

"Uh-huh, thaaaat's me! Star Butterfly!" She proudly announced, and the young woman clapped her rosy cheeks and let out a squeal.

"Ooooohhhhh, that has to be the best, name, EVER!" Mabel proclaimed with delight. Star beamed happily at the enthusiastic compliment and performed a thank-you bow.

Marco rubbed the back of his neck and smiled weakly at the Pines siblings. "Uh….huh. Okay, then. Sorry about getting so weird, I guess I was just...pretty surprised by the easy reception."

"Don't worry, it's cool. We're no strangers to weirdness." Assured Dipper. "Trust me when I say that we deal with quite a lot of it."

"But thankfully not everywhere! Or all the time either. Mostly just around here when we visit our great uncles,because it's like, Cray-Cray Central. But when freaky stuff does come up, we're pretty much total pros at handling it." Mabel then clasped her hands and excitedly leaned in close. "So! Now all that's finally out of the way, how about you join us and the rest of our family for dinner?"

"Wait, really?" Asked Marco, surprised yet again by the Pines quick acceptance and hospitality. "Well...I mean, that does sound nice, but…..we just kind of showed up out of nowhere, and you barely even know who we-"

"Pffft! Don't worry about it! Strangers are just people you haven't made friends with!" Mabel cheerily brushed aside his objections. "We can set up a couple extra places at the table, easy. And Soos is making his famous tacos tonight, and there's always plenty enough to go around!"

"Yeah, it wouldn't be a problem at all. And I'd honestly really like to hear more about what things are like on your end." Dipper then stepped that last remark back a little lest he came off as over-curious, knowing all too well that he could definitely be hyper-inquisitive to a fault at all. "I mean, we'd all really like to hear more."

"Thanks, but…." Marco was still being over-cautiously polite about the affair. "But….we probably shouldn't."

"Why not?" Mabel protested.

"It's no offense to you guys or anything. Honest! It just feels kind of...just like, really rude on our part. I mean, we totally messed up where we were going, crashed your world from out of the blue, and so I don't want you to feel pressured or anything to feed Star and…..Star? Star?"

His best friend had long since left the conversation. She was now currently and fully occupied with the little tots that were crowding around her. Star's eyes sparkled brightly with sheer joy as the children looked up at her with their big eager gazes.

"So awe you a pwincess?" Gladys asked as she bounced up and down.

"No, she's notta princess!" Finn gave his own opinion. "Lookit, she's gotta wand. That means she's a….a wizard! A girl-wizard! With magic powers an' stuff!"

"Pwincesses can be magicky too!" The little girl argued with her brother. Star tittered uncontrollably at the sight that the two tiny identical twins cut.

"Lucky for you little cutie pies, I'm both! Princess AND magic-wielder extraordinaire!" She performed a graceful twirl on her toes, and with a blast of her wand she created a small burst of fireworks that crackled up into the air. The children gasped loudly with awe.

"Ahbwa!" Phoebe squeaked excitedly as she clutched the teen's leg and watched the swirl of colors sparking above them. The little baby redhead made Star squeeze her fists and coo involuntarily.

"...Star? Star!" Marco kept calling impatiently. "Staaarrrr!"

"What?" She finally noticed.

"We should probably get going back-" He tried to suggest, and was immediately met with protest.

"What? Nooooo! These people are soooo nice! They just asked us to stay around for a bit, and look! Marco, just look!" With a sweep of her arms she gathered Mabel's twins and Dipper's little daughter up into her hold. "Have you ever seen babies this adorable in your whole entire life?"

"Star-"

"Babies, Marco! Baaaaaaaay-bieeeeeeees!" The smitten girl cooed as she flashed him doe eyes.

"Star, we totally crashed their dimension. It'd probably-"

"Nuh-uh!" If he wasn't going to give in easily, then neither would she. After cutting him off with a blunt refusal, Star turned on a dime and raced off around the Mystery Shack.

"Wait, Star! Star! Hey!" Marco yelled as he took off. "STAR!"

"Can't hear yooooooou! Too busy going off to have fun with my new buds!" She sang back. The tiny twins just cheered loudly in agreement, while Phoebe clung tightly to their strange but intriguing new friend. While one teen chased the other, the unfazed elder twins calmly watched on.

"I think they're probably sticking around." Dipper confidently concluded. He of all people know how futile it could be to try argue against strong-spirited women, thanks to being a twin sibling to one and a husband to a tough-as-nails lumberjill.

"Sounds good to me! I'll tell everyone that we got some guests joining us." Mabel rubbed her hands with happy anticipation. "Oooh, before I do that…. Hey! Hey! Star and Marco! I'm going inside. Either of you two want a drink or anything?"

"What do you have?" Star breathlessly replied.

"Soda, water, and a fresh pitcher of Mabel Juice-"

"I don't know what that last one is, but I'm pretty sure I want it!" Star said excitedly as she passed the siblings by, all while still carrying all the children and evading the panting Marco.

Mabel turned to her brother and flashed him one of the biggest, toothiest smiles that he had ever seen in his entire life. "Ooooohh, I DEFINITELY like her….."
