This is about the time Summerween happens in the show. Actually someone in another fanfic said it was June 22, so I'm a little late. However, I'm still going to do a Summerween chapter, taking some ideas from the show and adding in my own stuff. There's going to be two parts to this episode. Here is part one.

Enjoy!

Chapter 4: SUMMERween?

Zyon walked down the usual road he took to the Mystery Shack. His feet stopped and his eyes shifted to a building he never saw before on this path. The giant sign on the roof read, Summerween Superstore. His eyes narrowed with curiosity at the sign. Looking at his phone, he saw he had a half hour before his sift began at work. It was only a ten-minute walk from where he stood. He had some time to kill.

Upon entering the store, Zyon found himself immersed in a world of Halloween. He loved Halloween! Though, he was surprised to see the store popping up around this time of year. The brunette at the register eyed him carefully.

"Is there an adult with you?" she asked.

Zyon returned the same skeptical glare. "I'm fifteen," he said. The woman rolled her eyes and shook her head. Zyon noticed that she kept her eyes on him as he walked down one of the aisles. It seemed like many store owners in this town had problems with teenagers and children coming into the stores alone. Seeing what happened to the lady in that other store he visited not too long ago, he could see why.

As the teenage boy looked around at the fake, scary decorations, he heard some familiar voices. He peeked around a plastic witch by a caldron to see who it was. His eyes popped wide open as he saw Dipper and Mabel talking to Stan.

He heard the old man's gruff voice. "Get as much as your little arms can carry, kids! This is going to be the best Summerween ever!"

Mabel came running around the corner, almost running Zyon over. She halted immediately.

"Hey! Are you getting your costume for Summerween?" she asked.

"What's Summerween?" Zyon asked.

"Its Halloween in the summer!" Mabel exclaimed. "My grunkle is going to give out candy and me and Dipper are going trick or treating!" A tiny laugh escaped Zyon's mouth. "You two still trick or treat?"

Mabel's smile fell. "What's wrong with that? What are you doing for Summerween?" she returned sourly. Suddenly, his phone beeped.

He pulled out his phone and looked at the text.

Zyon shrugged. "I'm going to a party," he said.

He showed the invitation that Tambry just sent him. Mabel looked at the screen showing an orange flyer with black lettering reading, Tambry's Summerween Party: Bottles will be spun. No pictures better end up online.

Mabel did her own shrug with her hands. "Dipper and me will have our own party after we get all that candy! To the candy isle!" she screamed as she bounced off.

Zyon walked into the area with all the costumes. This was pretty late notice on Tambry's part, but it wasn't like he had any plans that evening after work. Speaking of which, he had to be to work in twenty minutes. Then again, his boss was at the store. He had more time as long as Stan was here too. His eyes scanned over the possible choices, a pirate, a vampire, a warlock, a hippie...choices...choices...

Grazing over the plastic bags, he saw one that called to him, Dragon Warrior. It was perfect! The garment appeared medieval with gold plated armor and armbands. There was also a fierce looking golden head garment with spikes protruding from the helm. He took the costume and headed towards the front. Suddenly a voice came over the PA system.

"Have the police eject the Pines family from the store!"

"Not today!" Stan shouted as threw a smoke bomb at the cashier and pushed a cart full of merchandize out the exit doors with his niece and nephew chasing after him. Zyon Slowly walked over to the counter as the smoke cleared. The woman still coughed and hacked for a moment. The large man who was the store's security walked over.

"You missed them!" the woman shouted angrily. The three looked outside as a red Oldsmobile backed into the telephone phone knocking it onto a giant billboard of a jack-o-melon.

"Let's move!" Stan yelled as he sped away.

Zyon slapped the costume onto the counter.

"Can I hurry up and pay for this, I gotta beat my boss to work!"

When Zyon got to the shack, he saw Stan's car parked diagonally on the grass. He let out a sigh and prepared himself for his boss's rant on him being late to his job. However, he walked inside to see Soos scowling down at him.

"You're late. Not cool, Dude."

Zyon raised an eyebrow. "You're lecturing me? Where's Mr. P?"

"He's uh—planning for tonight. You know its Summerween, right?"

"Yeah, that's the reason I'm late," Zyon explained. "I stopped by the store to get a costume." He showed Soos the dragon warrior outfit.

"Whoa! Cool!" he exclaimed. "So, you goin' trick or treating?"

Zyon rolled his eyes. "No, man. I'm going to Tambry's party?"

"You are?" he heard his female coworker's voice.

Zyon turned to see Wendy walk through the shop entrance. Soos crossed his arms as he stared sternly at her."

"Wendy, you're late too!"

"Oh, sorry Mr. Ramiez," she answered with a sarcastic tone as she rolled her eyes. "Are you being Stan today?"

"I had to. Stan took Dipper and Mabel to the summerween store. Someone had to stay here and take on the duty of managing the shack." He laughed lightly. "That a funny word, 'duty.'"

At that moment, Stan stuck his head into the shop from inside the house.

"Hey Soos, anything to report?" he asked.

Wendy mouthed to him, 'Don't tell him I was late.'

"Uh," he turned to see Stan furrow his brow with a stern glare. "Zyon and Wendy came in late," he said quickly then left the room. Wendy let out a groan.

"Soos!" she yelled.

Stan stared both his employees down. "So, both of you were late today?" Wendy looked away. Zyon saw the killer stare on his boss' face and broke.

"I'm sorry, sir!" he began. "I stopped by the Halloween store, or I mean the summerween store? Uh—I saw you guys there—"

Stan's glare softened. "You were at the store? Did you happen to witness anything like, I don't know, a basket of candy and decorations being pushed out the door after being paid for by my own currency I named Stanbucks?"

Zyon raised an eyebrow with a smirk lining his lips. "You mean, did I witness you shoplifting after throwing a smoke bomb at the cashier?" The two stood in silence, staring at each other.

"Uh, I'll let you two off with a warning. No more being late, okay?" Stan finished his half threat and hurried back into the house.

"Dude, that was awesome, Z," Wendy said.

Zyon smiled at the redhead. "I guess it's a good thing I went to the store." He held up his costume. "I'm wearing this to Tambry's party. It's cool, right?"

Wendy looked over at the picture of the model on the bag. "Yeah. I've got a costume too. You'll see it at the party."

"I don't get a hint?" Zyon tried.

"It's totally opposite of me," she responded.

Zyon narrowed his eyes in thought. "Like what? A fairy princess or something?"

Wendy burst out laughing.

"Oh my God! I'd never dress up like that! No, you'll see," she said.

A few costumers walked in and aimlessly wondered the shop. Stan walked in and began his usual spiel, trying to entice the couple to go on a tour.

As time went on, more and more visitors came to visit the Shack. One of these people was Robbie. As soon as the Emo walked in, Zyon felt the liveliness of the place drop. He made a direct path right to Wendy, leaning on the counter.

"So, I'll pick you up for Tamby's party around eight. We can get some food first.

"Sounds good," Wendy agreed. Then her eyes went to Zyon. "Hey, how are you getting to the party?" she asked. Robbie's eyes widened at the thought of the new kid getting invited to what would be known in this town as the biggest Summerween bash of the year.

"Whoa, Wait! How did you get invited?" Robbie protested.

Zyon opened his mouth to answer, but only a small sound escaped.

"What do you mean, Robbie?" Wendy said crossly. "He's hung out with us for a while. Why wouldn't Tambry invite him?" Robbie responded with a grunt.

"Yeah, man. Tambry and me are cool," Zyon answered. He felt a sense of pride when he told Robbie his confident connection to the group. However, the dark clad teen returned a glare and Zyon lost his words. Instead, he started his daily routine at the shop as he opened new boxes of snow globes, key chains, and bobble heads. He stacked the shelves full of the cheaply made items, periodically turning to eavesdrop on the conversation between Wendy and Robbie.

"So, how skimpy is this costume you're wearing?" Robbie asked with a dopey grin. Wendy playfully shoved him.

"Shut up, Robbie," she said giggling. "You'll see it at the party."

"But, I'm picking you up for the party."

"Yeah, I'm changing at Tambry's. She and I are doing the ensemble together."

Now Zyon wondered what her costume looked like. He began picturing her in whatever his mind came up with until he realized he wasn't getting any work done.

Stan walked into the shop leading the couple he took on the tour, inside.

"And here, we have the magnificent shop where you can find only the rarest of treasures to take home with you. For a price, of course," he curtly strung on. He turned to Wendy who was still busy talking to Robbie.

"And this lovely young lady is going to be a model employee and ring up any items you may purchase properly." Wendy still wasn't paying any attention. Stan cleared his throat. "Ahem!" Wendy looked up at her boss's stern face. She smiled and moved in front of the register.

"I gotta get going anyway," Robbie said, not even caring about Stan's burning glare on the back of his head. "I'll be back later." He carelessly walked out the door of the shop. Zyon breathed a little easier after Robbie left.

"After the couple left with their purchases, Zyon walked over to the register.

"So, I don't know where Tambry lives, exactly," Zyon said to Wendy.

Wendy's mouth fell open. "Oh Z, I'm sorry, we were talking about that and I totally spaced out on you. Did you want to ride with me and Robbie?"

Zyon pictured that for a moment inside his head. He wasn't sure he wanted to be stuck in a vehicle with Robbie driving.

"I can get a ride with Thompson," he said quickly. Wendy nodded.

The day moved on at a painfully slow pace. There weren't as many costumers as usual. However, Stan didn't seem to mind as he frequently disappeared into the house, mumbling about getting all of his tricks ready for the visitors later.

Thompson arrived at Zyon's place about quarter to nine. He was always punctual, but Zyon wasn't. He just got out of the shower when his ride showed up.

"Zyon," his mother called from downstairs. "You're friends are here."

"Just tell them to hold on a minute," Zyon called over the railing from the second floor. He quickly put on his costume, which was in parts. The black robe-like cloth was easy enough. Then he put on the gold rubber breastplate. It felt a little awkward, as if someone larger than him was meant to wear it. He slid on the cloth pieces on his arms and put on his black boots. Then, he put on the headpiece. From the picture, the headpiece looked pretty solid. However when he took it out of the package, it was a stupid piece of cloth connected to a bigger piece of rubber. He put it on and tied it in the back. After a moment looking himself over in the mirror, he pulled it off. No way was he looking like some fantasy roleplaying reject.

"Zyon," he mother called. "You're friends are waiting! Hurry up!" Her voice progressively grew impatient. He barely glimpsed at the mirror to check his hair, which spiked upwards as usual.

Moments later, he came running down the stairs. His mom turned to him.

"You have your phone on you?" He nodded. "Okay. Call me if there's any problems." She hugged her son, who returned the affection quickly, before pulling away and following his friends out the door.

Once in Thompson's van, Zyon felt the freedom of being out of the house.

"Hey Z," Lee greeted casually. Zyon high fived him, then turned to Nate and did the same.

"Hey," Nate said from the front seat. He turned to Thompson.

"Alright, step on it, T."

Thompson slowly applied pressure to the gas pedal as to not do anything harsh that would ruin the transmission of his mom's van.

The van drove towards a Victorian style home and parked on the street. Orange lights covered the front and fake gravestones stood throughout the front yard. Tiki lamps lined the walkway up to the house. Zyon made a small laugh as he saw the carved jack-o-melon on the porch step.

"I don't know. I find it weird that for Summerween, people carve watermelons, instead of pumpkins." Then he realized that pumpkins weren't in season this time of year. "Well, I guess it makes sense since it's June."

"Yeah, it is kind of strange," Lee admitted. "I've always lived in this town, so I've celebrated the holiday since I was born."

Zyon nodded. "True that."

Entering the house, loud music erupted in their eardrums. Not too many guests had arrived, but Zyon saw Wendy and Robbie in the corner. He walked with the other three he came with, as they walked to where Tambry stood with another girl Zyon didn't recognize. Tambry wore a black two-piece outfit with a cut off shirt and skirt. Black feathery wings hung on her back. Her friend wore a nurse outfit with a bunch of fake blood all over her white outfit.

"Yo Tambry," Nate yelled to her.

She glanced up for a quick moment from her phone. "Hey," she responded low key. The girl next to her with pink hair was also busy on her phone. "Oh, this is my friend, Korine. The new girl barely grunted a greeting.

"Hey Kor—een," Nate said.

She looked up from her phone. "It's Kor—ine."

"Right, so where's Tambry been hiddin' ya? I've never seen ya before?"

Tambry rolled her eyes. "If you're going to hit on my friend, Nate, at least don't be an ass while doing it."

"Oh, you thought I— Oh, that's funny Tambry," he forced a laugh. Zyon lost interest quickly and looked over at Wendy who was suddenly alone. He hurried over.

"Hey, Wendy," Zyon waved at her.

"Z! You're here. That costume looks really cool." Zyon looked at Wendy. She had the same clothes she had on earlier at the work.

"You're not in a costume?"

"Oh, yeah, I was going to wear this skimpy costume, but I decided not put it on till later."

"Oh. Do you have it with you?"

A small smile curved up on her mouth. "I'll be right back." Wendy headed out the front door. Zyon stared after her.

"So, you actually came." He turned to the voice behind him. He looked up at Robbie.

"Yeah. I never miss a party, man," Zyon answered coolly.

The other teen continued to glare down at him. "Just so you know, Wendy is my girlfriend now."

Zyon felt his stomach tighten. "Yeah, I know," he answered casually. "It's cool."

"Oh, really? It's cool?" Robbie spat at him. "Because I get the feeling you think you can actually get her to like you."

"She's my friend," Zyon clarified. Even though it pained him to say that, he knew it was true.

"Friend, huh?" Robbie scoffed as he walked away. Zyon let out a sigh. He hated to admit it, but that guy could be intimidating.

Everyone was standing around the snack table when Wendy walked in. All eyes jumped to her and her new choice of clothing. Her outfit was very similiar to Tambry's, except it was white. Huge white feathery wings hung off her back and she wore matching white boots to complete the ensemble.

"You actually wore it," Tambry said.

Wendy covered her body as she noticed everyone's eyes were on her. "Okay you guys, stop staring at me." Everyone went back to their conversation as Robbie walked over and put an arm around Wendy.

The night went on and most of the snacks were gone in the next hour. Zyon looked at his phone. It was almost eleven. Overall, the party was kind of boring. He wanted to talk to Wendy, but that wasn't going to happen as long as Robbie was around. His ears caught the conversation between Nate and Lee.

"Okay, we need to liven this party up. Thompson, I uh, dare you to eat all the loser candy in here," he said holding up a ceramic bowl.

"That's easy!" Thompson said.

"With the wrapper still on," Lee finished. Now, the heavyset kid looked unsure.

"Come on Thompson! Do it!" Nate urged. The two started chanting his name until everyone in the room cheered him on.

"Alright! Watch this!" Thompson poured all the candy into his mouth with the wrappers still on. They watched him chew, but suddenly, he started choking. He threw up the candy into the bowl. The others laughed as they watched.

Suddenly, someone knocked on the door. Wendy was the first one over to answer it.

On the other side of the door stood Dipper, Mabel and Soos.

"Hey! You made it!"

"No time! Let us in!" Dipper shouted.

The three ran inside.

"Question, can I use your bathroom?" Soos asked.

"Uh, yeah," Tambry answered while still looking at her phone.

"Thanks." He ran towards the hallway, then peeked his head back out. "Oh by the way, there's a scary monster after us and wants to eat us because we failed to get five-hundred pieces of candy." He ran off.

"What's he talking abou—" Wendy was cut off by a hard knock at the door.

"That's him!" Dipper squeaked.

Robbie rolled his eyes. "What's there to be scared of?"

"Fine, Robbie, if you're not scared, open the door," Wendy dared him.

"No! Don't!" Dipper cried.

"I'm not scared," Robbie said. "Thompson, dare you to open the door."

"No way!" he yelled. Then Robbie turned to Zyon.

"I bet you won't do it."

Zyon's eyes bounced from him to Wendy. "I'll do it," he said. Both of the twins yelled at Zyon to stop, but he kept going. He put one hand on the doorknob and turned. Everyone in the room held their breath as the door opened.

No one was there. Zyon turned to the twins.

"Man, you two are full of it!"

Suddenly, the lights went out. Fast paced footsteps could be heard on the roof.

"Is it going to come down the chimney?" Mabel wondered.

Everyone was silent. From above, it sounded like something scurried about from the floor above them.

"It's inside the house!" Tambry shouted.

"How would it get inside the house?" Wendy asked.

"The attic. There's a hole on one side of the roof where a bunch of squirrels chewed their way in."

"This thing is bigger than a squirrel," Mabel said.

Suddenly, they heard a scream from upstairs. "That was Soos," Dipper said in a panic. He walked over to the stairs and looked up into the darkness.

"Anyone have a flashlight?"

Zyon took out his phone. There was an app for a flashlight, but using it, took a lot from his battery. However, if Soos was in trouble, they had to go find him.

"Here, I've got my phone."

Dipper nodded and the two began to ascend the staircase. "Wait for me, bro," Mabel said.

"Me too," Wendy said as she walked over.

"Anyone else?" Dipper called to the rest.

All at once, the other teens ran screaming out of the house.

"Nope. Just us." Mabel said. The four started their way up into the darkness unsure of what they were going to find.

N/A: That's the end of part I. Part II will be coming soon. Thanks for reading!
