Hello my wonderful readers! I'm so sorry for taking so long to post another part. I got so caught up in school and exams, then I got caught up in summer, and now school's back, but I'm finally writing again. Just because it has been so long I'm reminding you that in the last chapter, it seemed like Bill knew Dipper was going to hurt you at the fair, which led to Dipper finding out that Bill is involved with the paranormal in Gravity Falls but isn't sure if he wants to tell you because you and Bill are good friends. Maybe rereading the chapter would be helpful?
Anyways, lets get to the story!
Mable's POV:
The day started with the usual maple syrup races between Dipper, Y/n and I. But things got a little more interesting when Stan came into the kitchen demanding that we all went for a ride in his car.
After a very bumpy car ride, Stan pulled into a parking lot and crashed into a handicap sign. He turned to us and announced, "Here we are, the Summerween Superstore!"
Dipper, Y/n and I looked at one another with a confused and curious glance.
"Wait, Summer-what?" Dipper questioned.
"Summerween!" Stan explained. "The people of this town love Halloween so much, they celebrate it twice a year. And wouldn't you know it, it's today!"
"I'm intrigued," Y/n grinned as she undid her seatbelt.
"An excuse to wear a costume and you get a bunch of candy... sounds like a good idea to me!" I declared.
Dipper and I undid our seatbelts and the three of us ran into the Summerween Superstore yelling, "TO THE COSTUME AISLE!"
We made it to the costume isle which had every costume from Spiderman to rainbow unicorns. As much as I wanted the unicorn costume, I had a better idea in mind. I took three costumes off the rack and handed one to each Dipper and Y/n.
"Go try the costumes on!" I smiled. "You guys are gonna love it!"
The two of them looked at me a little uneasy but still followed behind me as I skipped towards the change rooms with a big smile on my face. We all went into our own change rooms. I quickly threw on my costume and put on the matching hat. I stepped out of the change room and waited for Dipper and Y/n. It wasn't long before both of them stepped out in their costumes. Neither of them seemed to like their costumes very much, but I'm sure they were smiling on the inside.
The costumes were meant for three people. I was strawberry jam, Dipper was peanut butter and Y/n was a piece of bread. All of them were super cute costumes!
"Sooo, what do you guys think?" I asked in a sing-song tone. "Do you love it?"
"I love your creativity, Mabel, but I'm not sure I want to be a piece of bread for Halloween," Y/n admitted.
"Then what are you gonna be for Halloween?" I wondered. "Oh! An idea is happening here! You could be a... rainbow unicorn!"
"Actually, I have something else in mind," Y/n said walking towards the costume isle with a sly grin. She came back with a costume in hand, but I couldn't make out what it was. She walked into the change room and shut the door.
Dipper and I waited for a couple minutes. When Y/n immerged, she was wearing a form-fitting greenish black suit with tall black boots. She had a backpack over her shoulders and a pair of goggles rested on her forehead. It wasn't sparkly like the unicorn costume, but she seemed very happy in it, so I liked it. I wasn't sure what she was supposed to be, but clearly Dipper knew. I glanced over at him to find him staring at Y/n very intently. Someday, I'll use my matchmaking skills to get them together, it's so obvious they like each other. I'm just waiting for the right moment.
"What do you think?" Y/n asked softly as she fiddled with the backpack strap of her costume.
"It's no sparkly unicorn, but you look great!" I smiled.
"A Ghost Harassers costume?! No way Y/n! It looks amazing on you!" Dipper exclaimed, wide eyed.
Y/n's cheeks turned a light shade of pink. "Aw, thanks Dipper."
Dipper smiled and scratched the back of his neck. "I-I mean it. You really look amazing."
Dipper and Y/n stared into each others eyes. I stood back and admired the romance before I interrupted them. "Well, whenever Dipper is done drooling over Y/n, I say we should go have some fun!"
"Hey! I wasn't drooling!" Dipper blurted, trying to defend himself.
"Whatever you say, Dipping sauce," I laughed.
Before long, the three of us were out of our costumes and making messes around the store. Dipper was pushing me and Y/n in a wheelbarrow. We continued to knock over shelves and merchandise. I glanced over at Stan who was checking out the fake blood and subsequently spilling it everywhere.
Everyone in the store looked happy except for the cashier lady, she looked like she could really use some smiley face stickers. The cashier picked up a walkie-talkie and mumbled, "Have the police come and eject the Pines family from the store."
I looked over at Stan who was clutching a smoke bomb in his hand.
"NOT TODAY!" Stan yelled, throwing the smoke bomb.
Stan ran out of the store, barrels of fake blood in hand with Dipper pushing Y/n and I in a wheelbarrow behind him.
Dipper's POV:
After a very bumpy ride home in Stan's car, me, Mabel, Y/n and Soos were hanging out in the living room at the Mystery Shack.
"I'm so excited!" Mabel exclaimed.
"We're gonna have the best costumes, get the most candy..." I thought aloud.
"And have the biggest stomach aches ever!" Y/n laughed.
I love hearing Y/n laugh.
"Dude, I've never seen you guys so pumped," Soos said in his superhero costume.
"Well, back at home, me and Dipper were kind of the kings of Trick or Treating," Mabel explained. She pulled out our trick or treating scrapbook and showed the pictures of us in matching costumes. "Twins in costumes, the people eat it up. And now that Y/n is with us, its gonna be even better!" She beamed, flashing her big smile at Y/n.
"Well, you dudes better be careful out there. It's a night of ghouls and goblins. Not to mention... the Summerween Trickster..." Soos whispered eerily.
"The Summer-what-what?" Mabel asked.
Soos looked at us very seriously. "The Trickster goes door to door, so the legend goes, eating children who lack the Summerween spirit."
Well, you don't have to worry about us. We've got spirit to go around." I replied, throwing a piece of candy in my mouth. After a slight taste of the candy, I started to cough. "Ugh! What is this stuff?" I reached in to the candy bowl. "I've never even heard of these brands. Sand Pop? Gummy chairs? Mr. Adequate-Bar?"
Y/n rolled her eyes. "Seems like Stan to buy the cheapest candy he could find."
"It's looser candy!" Mabel complained.
"Quiet your discontent, children, lest the Trickster overhear," Soos warned.
I picked up the candy bowl and threw the loser candy out the window, ignoring Soos' warning. As I was throwing another handful of candy away, the doorbell rang.
"Trick-or-Treaters. Quick! Give'em that terrible candy," Stan yelled from his room.
I opened the door expecting to see some trick-or-treaters, but was greeted by Wendy and Robbie instead.
"Hey Dipper!" Wendy said happily. "I just came to get my jacket. I left it here. Again."
Robbie glanced at the candy bowl I had in my hands. "What's with the candy? You're goin' trick-or-treating or something?" He retorted sarcastically.
"Well actually I, uh-" I started.
"Shut up, Robbie," Wendy interrupted. "Of course he's not going trick-or-treating."
"No! Uh, yeah. Trick-or-treating is for babies. I guess..." I trailed off.
"You should come to this party with us. Tambry's parents are out of town, and it's gonna be OFF THE CHAIN," Wendy suggested as she handed me a flyer.
Wendy and Robbie walked out of the shack and got back in the van.
"Hey guys, wait! Maybe I'll see you at the party!" I shouted.
"It's at nine, don't forget!" Wendy called before she drove away.
I looked at the orange flyer Wendy had given me and sighed.
I know that I have plans to go Trick-or-treating with Mabel, and I know that I like Y/n. I know that I thought I was over Wendy... but at the same time, am I really over her? It's not like I can just turn off my feelings... Besides, it's only one night and I hang out with Mabel and Y/n all the time... What am I gonna tell Y/n and Mabel?
