Super Mabel Galaxy is a crossover with Nintendo's Super Mario Galaxy series and Disney's Gravity Falls. I do not own either one of the works. I do not intend to make this crossover for money, therefore I am not making this for profit; I do this for fan purposes and entertainment.

Super Mabel Galaxy is in Third Person Multiple, a work of writing when the narrator focuses on multiple characters (not as broad as Third Person Omniscient).

The inspiration of this crossover all started when Mabel Pines officially said, "It's a-me, a-Mabel!" (a reference on Mario's dialect) on that Rumble McSkirmish episode. ;v; I luv u Mabel!

This is a completely revised and edited version, where the chapters are shortened to approximately 1,000—2,000 words each, so it won't feel like you're reading a novel per chapter! XD And I've also removed some characters, as they were one too many and it felt very redundant and unimportant.

However, the elements of the story and its plot will remain the same.

Enough with this cheesy old Author's Note butt…

Enjoy!

"Happy birthday, kids!"

Mabel Pines exchanged silenced, astounded glances with her twin brother, Dipper. He mirrored the exact same confusion with her, despite the fact that they were twins.

Grunkle Stan had blew a party horn, which cued glittery, colorful confetti to shower down on the two baffled siblings. Grunkle Stan had his arms raised, looking down at the kids with a wide, toothy smile. He flitted his eyes sideways nervously.

"Er… haven't you guys remembered?" asked Grunkle Stan, surprised.

Mabel, once again, flitted her eyes at Dipper, who only replied with a shrug. "Is it Great Uncles Appreciation Day…?" trailed off Mabel, looking awkward. She would feel terrible if she had forgotten to by Stan a piggy bank to add with his collection.

Stan frowned. "No," he grunted. "I'm surprised that you've both forgotten about your own birthdays."

Dipper widened his eyes. "Ah, right!" he gasped.

Wendy, who rested her elbows at the front of the cash register counter, looked over at Dipper and Mabel with a laidback look in her eyes. "You guys are finally teenagers," she remarked with a slight grin.

Dipper looked over his shoulder at the lofty teenager. "We're officially teens!" he cheered with a fist pump on his small hand.

Coming from the dining room, Soos sauntered in. "Dudes," he said. "With it being your birthdays, you could possibly get something out of the shack for free!"

"Free?" Grunkle Stan instantly appeared at Soos's side, his eyes narrowed. Soos backed away a little from his glare. In one swift movement, Stan scampered over to the cash register, unceremoniously shoving Wendy to the side. He rapidly pressed random buttons to allow the tray to pop out, followed by a shrill ching. Stan dug his hand in the tray, shifting it from side to side momentarily, before pulling out two five dollar bills.

"Here's ten dollars for each of you," he told Dipper and Mabel, when he approached at their side, standing stiff. Mabel thought he looked as if he was going to break out in tears, but she couldn't tell clearly behind that gruff, stiff face of his. "Buy something, quickly, and furnish the money back to me. Got it?"

"Got it." Both twins said simultaneously and they went off, searching in different areas of the shack's main room.

Mabel gripped her five dollars firmly in her hand. She swam her eyes gently around, even though she was shaking like crazy in the marrows of her bones. Soon, she laid her eyes on a purple cap, resting on a shelf along with its copies. It looked a lot like Dipper's hat, only it had an apple shape stitched in the front. Mabel wasn't sure if she was used to hats. They could mess up my hair and make all the boys think I'm shabby, she thought.

An idea then came up in her mind like a lightning bolt. She rose to the tips of her toes and reached out her arms to grab the hat. "Come here, Waddles!" Mabel called out.

A plump, healthy-looking pig moseyed out from the dining room, his wet nose wrinkling in curiosity.

Once Waddles stopped at her side, she carefully placed the purple cap on his head. She paced back and leaned to her side, angling her vision on her pet, studying his flawless looks. She straightened up and clapped her hands together. "Oh, you'll make all the girl pigs roll in the mud!" she squeaked.

From the corner of her eye, she spotted Dipper walking up to Wendy, his face flushed. Beads of sweat were going down his face and his nose looked redder than usual. What does he have in mind now?

Dipper held up his arms, turning away shyly, his eyes closed tightly. His entire body stood stiff and Mabel noticed something glimmering in his hands.

Wendy looked down at what Dipper was holding; she gasped and her body, too, stiffened in a sort of way. "No way, where did you get those?" she breathed.

Realizing that Wendy's tone didn't sound at all offensive, Mabel watched as how Dipper turned his head back around, looking less tense. "They were in that dusty, old box next to that clothes hanger," he told her. He hesitated before adding timidly, "Do you like them?"

As if reluctant to answer, Wendy gently picked up the dazzling objects, which turned out to be silver, shining earrings in the shape of question marks. She observed them, as if expecting the slightest of blemishes. A warm smile then went on her face, from freckled cheek to freckled cheek.

"I like 'em, Dip," she commented casually, as if hiding the excitement she truly carried.

"They're for you," added Dipper quickly, followed by a mock-cough.

Wendy lowered her eyes at him, stunned. After a few moments, Wendy took a hand and ruffled Dipper's hat. "Thanks, doofus," she chuckled. "But remember, it's your birthday, not mines."

Dipper looked up at Wendy with glistening eyes before heading over to Mabel's direction. Mabel had suspected that Dipper knew that she was watching him the whole time.

"What did you get?" he asked her, suddenly drifting his eyes to Waddles.

Waddles reared up occasionally on his back feet and he oinked.

"Can I ask what this is all about?" asked Dipper flatly.

"Well," began Mabel, "I really couldn't find anything that suited me well in this old shack. So I bought Waddles a hat! Isn't he adorable?"

The pig reared up once more and rested his small hooves on Dipper's side, bowling him over. With Dipper playfully pinned to the ground, he refused and blocked his face with his arms as Waddles was brushing his wet nose to his cheek.

Mabel chuckled. Yeah, he's the cutest thing, alright.

After proudly singing the "Birthday Song", the crew had broken the tradition and went into a silent, mixed conversation, instead of blowing out the candles straightaway. Dipper and Mabel sat at a small table, where a light bulb hidden by swathes dimly lit the area. In the center of the table was a poorly-made cake. One of its sides were glittery and decorated with cats wearing sparkly bowties, supposedly representing Mabel's taste in bright colors. The other side was plain with white frosting.

As if finally realizing the cake's horrible demeanor, everyone's silent conversations faded to a stiff silence. Their eyes were rested on the cake.

Grunkle Stan cleared his throat dutifully in the silence. "I couldn't find a better cake designer in this blasted town," he announced nonchalantly.

Mabel rubbed her hands together, as if warming herself up in front of a campfire. Her eyes were round like moons and glistened with excitement.

Soos, who was standing behind her, rested his hand on Mabel's shoulder. "So," he said. "What is your wish?" His face then stiffened.

"Don't worry," reassured Mabel with a grin. "It won't be a talking horse."

Relieved, Soos sighed. "Well, what would it be, then, before we have laughing llamas, too?"

Something struck in Mabel's mind. She nearly rose in her chair light a rocket being ready to launch. She clasped her hands together and searched her eyes along the curious faces. "I've always wanted this wish, ever since I was eight," she exclaimed. As if she was made of a magnet, everyone had their bodies slightly leaned towards her; even Soos was faintly looming over her with watchful, wide eyes.

"My wish is to visit outer space! Yeah, sure, all the astronauts get to have their fun. But what I want to accomplish is something different. I want to meet aliens who are really good at fashion tips, and also ride of galactic ponies that shoot out lasers with their eyes. And maybe I can finally meet a space boyfriend named Leo!" She took time to catch her breath, as she was saying those things a little too fast to be caught in ones ears. She remembered Mermando, her old merman mate who was married to a dolphin now.

The face that was blossomed on everyone's faces made Mabel's heart skip a beat. They each seemed either uninterested or confused.

Mabel chuckled at the eyes that pinned her down. "Why is everyone so… quiet now?"

Dipper was the one to respond towards her hyperbolic imagination. "Because it's illusory, Mabel," he said with a frown on his face, elbows rested on the table. He was looking businesslike since Wendy was standing next to him. "Maybe try wishing for something more realistic next time. Remember, we're teenagers now."

Stung, Mabel felt the eyes go to Dipper as he began telling his wish on becoming a detective. He's right, she thought soberly. He's being haughty only because Wendy's here. If she knows about Dipper's crush on her, then why is he still trying to impress her? Once Dipper's wishing came to an end, Mabel looked back up at the table. One day, I'll prove that having imagination isn't a bad thing.

A thunderous clap came from Grunkle Stan, who didn't seemed intrigued by either wish. "Alright, just blow the candles out already," he grumped. "My favorite game show comes on at five."

Both twins exchanged happy glances, untouched by their great uncle's grouchiness. Concurrently, Dipper and Mabel inclined forward at a respectable distance between them and the cake. Both lips puckered, they allowed a gentle waft to flow and curl from their lips.

The candles were out.

Grunkle Stan noisily pushed his chair back and shot to his feet. "It's five o'clock! I gotta' go—!"

Instantly, the cake somehow exploded into tiny bits of cake and frosting. Startled gasps came from everyone as the cake was utterly ruined. That cake was terrible anyways.

All eyes locked onto something new that stood on the table: a turtle-like monster covered in the cake remains with black, beady eyes and a bib with a messily-drawn mouth on it. His shell was studded with spikes and he had russet-colored hair, almost like an erect ponytail in flames. It laughed cockily in a childlike voice, its hands on his shoulders. Everyone was frozen in place until the monster went "boo!" Everyone yelped. The little monster chuckled. Everyone yelped again.

"Silence!" snapped the monster.

From behind Mabel, Soos's body had seemed to unstiffen. "Whoa, cool," he gasped. "It's a dino-dude!" He sounded rather fascinated then startled.

The little turtle monster swung his head up at Soos, his eyes flaring with fury. "Who dares call me that?" he sneered. "I am Bowser Jr.! And you must follow my commands!"

Fear ebbing away, Mabel took detail on how less scary this creature was starting to look. He was probably nothing but a young, vulnerable baby. "You're so cute!" she cooed.

Shyly, the creature gave her a sidelong glance. "Cute?" he echoed disbelievingly, kicking a large piece of cake to the side, as if revealing his roguishness and proving her wrong.

Grunkle Stan stared down at Bowser Jr blankly, his fears gone, too. "Okay, so the cake designer added a special surprise in the cake, too?" he said to himself matter-of-factly.

"Fools!" growled Bowser Jr, folding his tiny fists in a shaky ball. "I'll rip your precious Mystery Hack from the roots!"

"It's 'Mystery Shack'," pointed out Dipper blankly. "The 'S' is poorly dangling from the sign. What have we don't to you?" he asked quickly, looking just as confused as the rest.

Out of nowhere, thunderous cracking sounded above in the ceiling. Pieces of wood began raining down on them, dappling the table. Mabel looked up in fright as large metal pieces crunched their way into the shack's ceiling. They appeared to be like large, metallic hands gripping a hold on the shack itself.

Everyone around her began to panic, scurrying around like vulnerable sugar ants, except for Bowser Jr, who remained on the table, a smug look on his face.

"Let's get out of here!" shouted Stan as he passed by.

Suddenly, the ground had seemed to shift beneath Mabel's feet. When she leapt out of her chair to run away from the table, she noticed that some of the objects in the room were gradually sliding to one side of the room. She began sliding, too. What is going on?

Fear and excitement gripped in her chest. "Dipper!" she called out in fright, realizing that he wasn't at her side, especially at a time like this.

To her relief, Dipper came scurrying at her side. "Mabel," he panted. "I don't know what's going on!"

"Me neither," she replied nervously. She looked back to find that Bowser Jr had left the room. Where is he up to?

"Come on," said Dipper beneath the groaning and crumbling of the shack. "Let's find a way out of here." He grabbed her hand and they scurried through the room.

Suddenly, the ground had vanished beneath Mabel. She soon felt the whole world blur around her. We're falling! Her chest tightened as she and Dipper plummeted down for a short time, landing hard on the soft, luscious grass.

Fatigue washed over Mabel's entire body. She could feel Dipper breathing rapidly at her side. She could hear the occasional pecking of woodpeckers, but they were barely audible under the immense groaning of the Mystery Shack.

Having time to recover, Mabel opened her eyes. Her heart lurched when she realized that she was looking at a large hole in the ceiling… But they were sprawled out in the grass… did they get a new grass carpeting inside the shack?

"Mabel…" Dipper's weak voice sounded from beside her. "We're fallen through a hole."

Fully aware, Mabel rose up on her bottom. She and Dipper were seated on the grass, a few bruises along their exposed legs. She then felt Dipper's body stiffened. She followed his gaze and her heart nearly stopped at once. The Mystery Shack's being carried away into the air! Along with it, they saw a long, silver, metallic had that seemed to grip to the shack's roof. The silver arm glinted in the orange light of dusk. It was attached to another large thing that hovered high in the trees. It had the appearance of an airship.

Still inside the perilously swaying shack, Grunkle Stand ran against the front door, rapping it furiously. "No! The door's locked!" he shrieked. "Not today, world, not today!" He stopped and turned around to press his back against the front door, trying to maintain his balance with the swaying shack.

With the shack sloping sharply towards Stan's direction, Soos slid towards his direction and smacked hard against the front door. "Well," he said enviously. "Wish I had a birthday as epic as this."

Scanning his eyes around the main room, which was piled over in sides with valuable and invaluable items, he noticed that the redheaded teenager wasn't present. "What a minute," he mused. "Where's Wendy?"

Soos sloshed his eyes around. "She was just at the table," he said, before adding fretfully, "But what about the twins?"

Bowser Jr scampered along the long metallic piece that bridged between the shack and the airship. He leapt and landed squarely inside the massive airship. He released a shrill laugh. "Victory is ours!" he exclaimed, rising his arms in the air. He then walked over to another creature, a much larger version of Bowser Jr, only his russet hair flowed back and his spikes were more deadly. "Dad, we got her!" he told the larger monster. "Let's get out of this place!"

His "dad" looked over his shoulder, his burning red eyes sizzling with gratification. "We've got her," he announced in a low, thunderous voice.

Sorry this was slightly long! ;-; on the older version of SMG, I've had people complaining that it was 'too long'. I'm trying my best to not make the chapters succeed 3,000 words! But then who would want a really short chapter?

Speaking of chapters, there would actually be more of them, since I'm splitting the long chapters up. You're welcome.
