"MABEL'S IT!"

Once upon a time, there was a small playground in Piedmont, California. It was a beautiful, almost summer day, and elementary school students were swarming the slides and swings. If someone was too walk by, they would quickly point out the screeches of laughter as the children played their games, whether it be slaying the dragon or hide and seek.

One particular group of children had decided to play tag. It had been going on for the entire recess, and the one to be "it" when the bell went off would be the loser.

This brings us to Mabel Pines.

Mabel was very tired. She had been avoiding "it" all recess, and now "it" had been unavoidable. She had been against a rock and a hard place this time. Now she was at risk of losing, and if she lost, it would taint her perfect record. She hadn't lost once this entire year, and with one day of school left, she wasn't about to lose her streak.

She knew she only had mere seconds left before the bell rang, so she would have to act fast. Mabel scanned the playground, looking for any one of her playmates to tag before the bell rang. She swung her head frantically before her eyes locked onto her target.

Grenda.

Now, Grenda wasn't the fastest kid on the playground, but her strong spot was definitely how good she was at climbing the monkey bars. If she made it there, then there was no way that Mabel would be able to catch her. However, by judging the distance between Grenda, the monkey bars, and Mabel, she was sure she could make it.

Mabel pulled out all the stops, and sprinted straight towards Grenda. Grenda, though oblivious at first, quickly realized that Mabel was after her, and took off straight towards the monkey bars. Mabel was in a high speed chase, and Grenda was simply running for her life.

It was the most intense game of tag ever.

Unfortunately, it couldn't last much longer. Mabel was running out of juice, and the teachers were lining up to bring the kids inside. She only had one shot at winning this thing.

Mabel sped up just enough, and right as Grenda hit the monkey bars and the teachers rang the bell, Mabel caught Grenda's shoe ever so slightly.

"GRENDA'S IT!"

"RIIINNNNNGGGGGGGG!"

All of the kids on the playground began to walk over to the door, and Grenda let out a sigh.

"How do you do it, Mabel?" Grenda asked. "You always manage to win, just by the end of recess. You're a miracle tagger!"

"Oh Grenda," Mabel giggled. "It's nothing, really. I think it's just the luck of-"

Mabel threw her arm to the sky. "My MILLION SLAP BRACELETS!"

There, on Mabel's arm, sat several multi-colored bracelets, all different patterns and sizes. Grenda looked at it in awe, and then they both laughed.

Suddenly, they found themselves at the door. As Mabel was about to go in, Grenda held the door open.

"Aww, thanks Grenda!" Mabel said as she skipped in.

"You're welcome, you TAG CHAMPION!" Grenda roared. Suddenly,one of the teachers turned to the large 3rd grader, and put up a finger to her lips. Grenda and Mabel quickly nodded. As soon as the teacher turned back, the two giggled quietly, and said goodbye as they went to their respective classrooms.

As soon as Mabel walked into her classroom, she was on the lookout for her brother, Dipper. She spotted him at his desk, reading another one of those nerd books. She would never tell him that, though, just cause it might hurt his feelings. She quickly slid in next to him, and he immediately smiled.

"Hey, Mabel," he said quietly, " did you keep your record?"

Mabel looked at him seriously, and put her hand up to her forehead in salute. "You better believe it, sir!"

The twins giggled to themselves as everyone began to sit down. Dipper looked at his sister again. "Congrats, Mabel."

"How about you, Dipper? Did you finish your book yet?"

Dipper looked at her excitedly. ""I'm almost done! I have just gotten to the part where the robot from chapter 6 is revealed to be the key to the Dungeon of Epipheron, and then Sir Jackson is-"

Mabel listened intently to her brother as they were handed their math sheets. Eventually he realized he had homework in front of him. Dipper looked intently at the paper, and rushed through the problems. As soon as he was done, he preceded to help Mabel with hers. The twins finished rather quickly, and continued to talk about their day.

As soon as math was over, Mabel helped Dipper stumble through the end of the year art projects that were due. She had been done weeks ago, and merely had to put the finishing touches on her statue before it was done. Dipper, unfortunately, was still struggling with his toothpick picture frame.

By the time the twins were finished, the school day was over. Saying goodbye to their school friends and their teacher, the pair of Pines left, eager to start their summer.

With the sun high in the sky and a small breeze brushing their faces, Mabel and Dipper began to walk towards their home.

"You ready for the summer, bro-bro?" Mabel said, punching Dipper.

"Uh… Ow.." Dipper rubbed his shoulder. "Yeah, I guess so. It'll be nice not to have to hear everyone scream and talk all the time."

Mabel grinned, but on the inside she felt her stomach droop. She had always known that Dipper wasn't exactly the strongest or biggest kid in their grade. In fact, he was always a little sick. He even had to stay in from recess because the teacher didn't want Dipper to hurt.

"Well this summer is gonna be epic! Imagine it! We're gonna build tents, create box forts, I'll finish my sweaters, and you can even beat that game mom and dad got you for Christmas!"

Dipper smiled. "Yeah, I guess so. Summer will be pretty fun."

"That's right!" Mabel said, bringing Dipper into a side-hug. They laughed, and continued to walk down the block.

Since it was a special occasion, their mom and dad bought them pizza with all of their favorite toppings. For Mabel, there was pineapple and pepperoni. Dipper preferred the side with sausage and green peppers.

However, that wasn't the only surprise waiting for them.

"Come on, Moooooommmmm, I wanna knowwwwwww!" Mabel pleaded. Dipper was still quiet, but even Mabel could tell that he was curious.

"That would ruin the surprise, Mabel," their mother smirked as she started the popcorn in the microwave.

"Why do you torture us?" Mabel groaned. Their father laughed.

"Come on, let's just show them, dear."

Their mother mock-rolled her eyes, and gave one last wink to the twins. "Fine. I guess we've bothered them enough."

The family of four went directly to the couch, and sat down. While Mabel was wiggling in anticipation, her father inserted a disk into the TV. The screen blinked to life, and suddenly, a brightly colored screen was in front of the twins.

Dipper's mouth was wide open. Mabel was speechless.

"So, kids, what do you think?" Their mother whispered teasingly.

"No way! It's the Ducktective Movie!"Dipper yelled, excitement clearly written on his face. Mabel quickly hugger her father.

"Thank you, thank you, thank you, THANK YOU!" The twins yelled simultaneously. Their parents chuckled.

"Yeah, yeah, now shall we watch the movie?"

For the next two hours, the family was engrossed in the thrilling scenes of the duck detective, solving one of the most complicated (and, of course, cheesy) cases of his career. By the end of the movie, the family had laughed, cried, and had even thrown a popcorn kernel or two. It had been fun, and exhausting. Dipper and Mabel tried their best to stay awake, but they were out cold. Mr. Pines picked up the children, and whisked them upstairs to their beds.

Mrs. Pines smiled, knowing that she couldn't have wished for a better family. She began to pick up the spilt food and pillows. She had finished cleaning up the small mess, and was on her way to do dishes when Mr. Pines came back down.

"Well, what do you say, sweetie? Was the movie as thrilling and as mysterious as the back of the case said?" Mr. Pines said teasingly as he handed her Dipper's popcorn bowl.

"Why, I say, Sherman, I could not simply believe the ending! It was quite the twist ending, was it not?" She said in a terrible British accent. Her husband smiled and shook his head.

"Well, the kids sure did have fun. It was nice to see Dipper and Mabel happy. I know they've been a bit busy with school activities and what not."

Mrs. Pines turned off the faucet, and laid the bowl in the dishwasher. As she shut it, she turned to her husband. "Yes, it was was. They sure did enjoy seeing that film."

Mr. Pines walked over and hugged his wife. "I'm not so sure that was all they enjoyed. I imagine just enjoying family time was enough for the two of them."

They stood their for a moment, and Sherman Pines gave his wife a kiss on the cheek. "Well, my dear, what do you say to a goodnight's sleep? Mystery solving with a duck detective and dealing with two popcorn throwing maniacs sure can make a man tired."

"Well, Mr. Pines, I imagine that-"

Suddenly, her sentence was cut off with a ring. It caught both of the adults off guard as they jumped ever so slightly. Mrs. Pines walked over to the phone with a frown.

"Now who would be calling at this hour?"

She quickly pressed the talk button. "Hello? Who is this?"

"Why, Mrs. Pines. Long time, no see."

Her breath hitched, and she stood their for a minute.

Her husband stood their in silence for a while, and then registered the signs of horror on her face. "Hun, is something wrong?"

She put up her hand, and sent her husband a frightened a look that told him all he needed to know. He stepped back, in fear.

"Now?" He mouthed.

"Mrs. Pines, I do tire of waiting."

She quickly cleared her throat. "What do you want? I know you don't make social calls."

"Oh so observant of you." He said sarcastically. " For your information, I simply called to check up on my favorite pair of twins. Now is that a crime?"

"For you it should be," she muttered quietly. "They have been fine. Nothing for you to worry about anyway. They've been normal, easy to raise children. Not even a behavioral issue, although I imagine that you already know that."

"Hmm, It seems as if you right. Unfortunately, everything didn't exactly work out in my favor. However, a deal is a deal, I suppose. You get to keep the twins, providing that you did keep the only other promise we made?"

"Stanley and Stanford know nothing about the kids," Mrs. Pines affirmed. "Though why it is so imperative that they know nothing is a mystery to me."

"And a mystery it shall stay. The money will continue to be deposited into your account, my dear. It seems as if this will be the last time we ever speak."

She gritted her teeth. "Forgive me for finding it refreshing."

"Ahh, tongue as sharp as ever. It has been a pleasure to work with you."

Before she could reply, a beep signaled the call over. She sighed, and put the phone back on its charger. Mrs. Pines leaned against the counter in silence for a moment, looking at her feet.

Sherman looked at his wife for a moment, and approached her cautiously.

"Is everything alright?"

She looked up at him with a smile on her face and tears in her eyes.

"It's over, Sherman. It's finally over."

The man looked at her in bewilderment, and brought her into a bone-crushing hug. They stood their in the kitchen, both eyes sparkling with joyful tears.

"The twins," He whispered. "We get to keep them? Forever?"

Her voice, soft and almost silent, suddenly brought itself to his ears.

"Yes."

She could feel his body shaking as he cried. Mrs. Pines also cried, tears rolling down her face. The couple continued to cry. Until finally, she broke the hug, and looked up to the man she married.

"I will finally sleep well, knowing my kids are safe."

"So will I."

The couple walked up the stairs, hand in hand, glad that their journey on a dangerous road was finally over.

Little did they know, the danger had only begun.
