"...Mabel?"
She didn't even seem to hear her brother; she was still glaring up at Ford, crushing the bouquet of flowers in one trembling hand.
"You are not welcome here," she said icily. "You need to leave. NOW."
The bright, eye-piercing light that was filling this world suddenly took on a slight red tint. All the cute animals and brightly colored people stopped in their tracks, an turned their heads in the group's direction, just like something out of a horror movie. The fact that the vibrant eighties music was still playing at top volume did not help at all.
Ford barely stopped himself from drawing his gun. Instead he slowly knelt to be on his niece's level.
"I understand that you might be a little upset with me-"
"You're not listening to me." Her voice trembled with rage. "Mabeland doesn't allow jerks who destroy families. This place only allows perfection, and never-ending summer!" A few seconds later a purple, heart-shaped cloud appeared over her head, and a rain of sprinkles poured down onto her head; she stuck out her tongue to catch a few bites, without taking her glare off Ford. She swallowed them, and then continued. "You are banished, Great Uncle Ford." She snapped her fingers, and suddenly a pair of giant waffles, with giant muscled arms, began marching towards them. Or at least putting on the appearance of marching, since they had no legs to speak of. They were floating in a very authoritative fashion.
Ford got to his feet, and quickly drew his gun, blasting both of them into pieces. Mabel just clapped her hands, and four more appeared.
"Mabel, we don't have time for this!" Dipper pleaded. "Weirdmageddon is happening right now, and-"
"And blah blah blah, some kind of crisis is going on that's got you in a tizzy, right?" Suddenly Mabel's glare was focused on him. "Well guess what, Dipper? Here in Mabeland, there are no crises besides figuring out whether I should have ice cream or chocolate cake for breakfast! Or both, with edible glitter all over them! I got my wish of endless summer and never having to grow up, and I am not giving it up! So you better either get used to it, or leave here with him!" She pointed at Ford with the now very-crumpled bouquet...and then looked away. "That's what you were gonna do anyway," she whispered bitterly.
Despite himself, Ford flinched before shooting down the newest group of giant sentient waffles. He hadn't expected...this. Not from the perpetually cheerful girl who had complimented his hands the first time they met, and who didn't seem to have an unhappy bone in her body. But it was becoming rapidly clear to him that he'd been wrong about that, too.
Mabel took a deep breath, and then turned her gaze on her three other friends with her familiar bright smile. As she did, the lighting returned to normal, and all the other inhabitants, except for the waffles, resumed their previous activities.
"You guys are welcome to stay here with me, though. You can have anything you want; Mabeland will provide it, sometimes before you even know you want it!"
She clapped her hands, and seconds later they were all cleaned up, torn clothes as good as new and injuries gone. A flying hamburger began hovering next to Soos's head; after a second's hesitation he turned and bit into it.
"Whoa, pudding center. Nice!"
Wendy elbowed him in the side. "Soos!"
Soos smiled sheepishly. "Sorry dude. I couldn't resist."
Mabel gave an annoyed glance over her shoulder as another soldier disintegrated. She sighed and clapped her hands; another ten appeared. "He's going to get tired eventually. When he does, he'll be banished forever and we can get started planning a big party, now that you guys are finally here!"
"Um, Mabel-" Wendy began.
"In the meantime, I already have some surprises for you!" Mabel clapped her hands again, and the three of them were surrounded by people.
All of Wendy's friends were there, looking happy and carefree-even Thompson. "Wendy!" Nate cheered, grinning and slinging an arm over her shoulder. "We missed you! C'mon, let's go vandalize some stuff!"
Wendy tried not to match his grin.
A luchador with a big mustache beamed at Soos. "I have returned to you, my son! Would you like to go play catch?" A baseball and catcher's mitt appeared in his hands.
Soos let out a small, delighted squeal, while his hands rose to either side of his pudgy face.
A tall Asian boy appeared at Candy's side, who appeared to be from a Korean drama film. He smiled and winked at her, before saying, "Nawa hamkke, gaja segsihan agassi."
Candy's pupils dilated. "All my dreams are coming true." She started to reach for his hand-but then quickly pulled away. "No! Fight it, Candy! Be strong for Grenda!"
Mabel blinked. "Wait, Grenda? What happened to Grenda?"
Before Candy could answer, there was a horrified scream behind them as the last waffle soldier was blasted into pieces, which slowly oozed syrup onto the ground.
Ford strode towards them, with Dipper hurrying at his side.
"Mabel, I'm sorry about our fight, and that things aren't great right now, but we're not letting you stay here," Dipper said quickly before she could open her mouth. "We can't stay here; it's not a good place, no matter how nice it seems. You need to come back to the real world with us."
All the stuffed animals gasped, and covered their mouths in shock. Even the sun (which of course was wearing sunglasses) made an appalled sound.
Mabel's eyes widened...before narrowing back into that unsettling glare. "Oh, you've really done it now, Dipper. You just broke our one rule: never, ever, EVER mention reality!"
Seconds later, a glowing light appeared behind her, which opened up to reveal the red, raging hellscape that was the real world.
"I guess if you want something done right, you have to do it yourself." She clapped her hands.
Seconds later, both Dipper and Ford had risen into the air, and were being levitated towards the portal.
Dipper looked to Ford in desperation-and saw that despite his clearly trying to remain calm, his eyes were wide with terror.
Because this happened to him thirty years ago. He got in a fight with part of his family, and-
"Wait!" he protested, squirming futilely in the air, "Don't we at least get a fair trial?!"
They stopped, and the portal closed up again.
"Oh, you want a trial?" Mabel asked darkly. "Fine. We can have a trial." She lowered them to the ground. "We can have it right. Now."
"How ya feeling, Goldfish? Had enough yet?"
Stan struggled to get a handle on his raspy breathing, before glaring through swollen eyes at the triangle and his ugly minions.
"Heh. This is nuthin' compared to what I went through in Colombia."
Bill sighed, and began circling him with his arms behind his back.
"Stubbornness really does run in the Pines family, doesn't it? Even when you have nothing left to lose, you still think that you have something worth fighting for. It would almost be cute if it wasn't so dumb."
The gaggle of monsters surrounding him cackled and gibbered in agreement.
"Try shooting lightning at him, boss!" the pink one hissed. "I love how they smell when you do that!"
"Yeah, make his heart stop!" the blue one who'd captured him suggested. His jubilant smile faded when he saw the looks everyone was giving him. "...What?"
"We need him alive, Keyhole," another of the monsters growled. "You forget that already?"
"Uh-no, I just-"
"FLAY HIM," the one with a giant binky said around it.
Bill floated back into Stan's line of vision.
"Things can get a lot worse for you, Stanley. But just tell me what I want to know, and it can all stop, right now."
"Okay."
He blinked. "Wait, really?"
"No." Stan tilted his head back, and spat out a thick red glob right into Bill's eye.
He grinned savagely as the triangle screeched, and frantically tried to clean it out.
Soon after, Stan started screaming again.
I apologize if Mabel's hostility or level of insensitivity seem a little out of character for her. My belief is that Mabeland is specifically designed to draw out the worst aspects of her personality, and amplify them tenfold. Plus she hasn't been here as long as in the show, so her anger and hurt over Dipper and Ford's perceived betrayal are still fresh.
Also, I apologize if Google Translate butchered the Korean.
