One Foggy Summerween

A/N: Hello, the Halloween season inspired me to write this story. Hope you enjoy it!

Prologue: We Need Costumes!

Mabel Pines just finished sewing the last stitches of her costume. Her lips curved into a smile as she looked over the colorful design. The woven fabric formed every type of hard candy one could think of, from suckers to gummy candy.

"Dipper! It's ready!" she called.

The thirteen-year-old boy rushed into their room. His sister held up the collage of colors.

"Here you go?"

Dipper eyes sprang wide open and his mouth fell into a frown. "Uh, I'm wearing that?"

"Yeah!"

"I'm not wearing that," he said.

Now Mabel joined him with a frown. "But the candy thing was your idea," she reminded him. Mabel was so excited for this year's Summerween. She and Dipper were first introduced to the holiday the previous year when they first came to Gravity Falls. There was a Christmas in July so why not a Halloween in June?

"I'm dressing up as the chocolate bar. I thought you we're going to be the hard candy," Dipper tried to help her recall the original plan.

"Oh." Mabel walked over to the long, freestanding mirror across the room and held up the costume to her body. "I guess this would mesh with me better." She turned to her twin. "But I made it with your measurements."

"Try it on to see if it fits," Dipper suggested. Mabel threw it over her clothes. She forgot to account for the fact that she would be wearing it over clothing and she had grown a bit from last summer. "See, it fits you great!" her brother complimented.

Mabel turned towards him and replied, "Okay. I'll wear this one. Now I need to start on your costume. Are you going to be a plain chocolate bar or a nutty chocolate bar?"

"No nuts. You're nuts enough for the both of us."

The two laughed as Mabel took off the costume. She grabbed the measuring tape, putting it around her brother's waist.

While the twins worked on Dipper's costume, the elder Pines twins were rummaging through the hallway closet. Stan grabbed parts from costumes he'd used in previous years. Everything was stored in a boxes and it wasn't very organized.

"This is going to be the best Summerween ever!" he exclaimed as he hand various costume parts to Ford. "It'll be just like when we were kids! Remember when we dressed up as mutants or aliens? Or mutant aliens?" he went on.

Ford nodded and laughed. "I actually do. But, aren't we too old for this, now?" Stan froze for a moment with raised gray eyebrows.

"Too old? You're actually saying that after everything that's happened? Both of us should be dead by now, but we're not! So, I'm living it up until I am! Here, take this scary wolf mask." Ford took it while rolling his eyes.

"Okay, so what are we doing exactly?"

"It's great! Every year I dress up in a scary costume and I have a bunch of trick planted up my sleeve, as well as every other part of my body. When the kids come get candy, I scare the crap out of them!"

"That doesn't sound very nice."

"It's not about being nice! It's Gravity Falls' second Halloween, and the people here go nuts over it. It's a time to scare a bunch of costume clad children who come to your house begging for candy." Stan threw his arm around his brother.

"And this year, I get to spend it with my brother, a man I have come to have a great deal of respect for, especially after a year with him on a small boat in the Artic." A tear fell from his eye that he quickly wiped away. The biggest smile graced Ford's mouth.

As Stan pulled more items out of the closet, Soos trotted down the hallway wearing his usual happy grin on his face. He stopped and acknowledged the two brothers.

"Hello, Mr. Pines and Dr. Pines,"

Ford shook his head. "I've told you before, Soos, you don't need to address me so formally."

"Uh, I didn't think I was supposed to dress you at all, sir."

The elderly scientist couldn't help but chuckle. "Soos, you are an original."

"An original what?"

Ford continued laughing. "Alright, that's enough of that." He now held a fury wolf costume and full-headed wolf mask in his hands. "This will be interesting." He turned to Stan. "Do I really have to wear this?"

"No. You could wear the wolf boy costume I put Dipper in for one of my attractions last year."

"Wolf boy? What would I have to wear?"

"Wolf ears, nose and tights."

"You made Dipper wear that? Wasn't he embarrassed?"

"Hey! I had to toughen that boy up when he first got here," Stan insisted.

"Well, there's no way in hell I'm wearing that," Ford returned bluntly.

Stan returned a wide grin. "So it's settled. You'll wear that wolf costume," he pointed at the gray fury ensemble.

Ford let out a hard sigh. "Fine."

Dipper came down the stairs, as there was a knock at the door. He kept a casually stride as he continued over to answer it. Wendy stood on the other side with a cool smile, holding out a flyer.

"Hey!" the teenage boy greeted. His eyes fell to the piece of paper with a black shadow forming a skeleton and dripping blood red letters reading, 'Wendy's Summerween Bash.'

"It's that time of year!" she exclaimed.

"Oh, you're throwing another party?" he asked.

"Yeah, but this year it's at this barn. We're doing a haunted hayride too."

Dipper raised a skeptical eyebrow. "Isn't that kind of—I don't know—kiddish?"

"Not the way we do it!" she replied with great enthusiasm. "It's going to be much better than last year! And I want both you and Mabel to come."

Dipper's mouth opened in a wide, excited smile, but then it dropped. "Uh, I don't know if Mabel will go for it. She wants us to go trick or treating again."

"You can do both dude. The party doesn't start until nine-thirty. Go trick or treating or whatever, then come party with us."

Dipper nodded. "Okay."
