The Triplets' Guides (Reader Insert Version)

(y/n)'s Guide to Anger Management

Dipper was looking between his two sisters with a rather timid expression on his face.

"Did I miss something here?"

(y/n) was now outside, working on yet another invention on the porch of the Mystery Shack. She reached over to grab the wrench, only to get shocked by a wave of electricity the instant she touched it.

She screamed in pain before letting go, and looked down to find that hooked to her wrench was an electrical cord.

Mabel appeared in the open doorway of the shack, swinging the other end of the cord in her hand.

"I bet you had a shocking time!" she joked, before bursting out into laughter.

(y/n) was taking in several haggard breaths, using all her will to bite back any words she so desperately wanted to use right now.

She was now walking into the women's restroom in the gift shop, but before she went in, she scanned the perimeter cautiously, checking for any signs of Mabel.

When she had deemed it clear, she went into the bathroom, and the door swung closed behind her.

Unknowingly to her, Mabel stepped out of her hiding place from behind a rack of T-shirt, and crept up to the door, peeling off the fake women's restroom sign off the door, revealing the real sign underneath: men's restroom.

There was the sound of a scream coming from the other side of the restroom door.

"Get out! This is the men's room!"

"Sorry!"

A few seconds later, (y/n) burst out the men's restroom door, her face flushed red with embarrassment.

Mabel was laughing at her sister's red face, the fake women's restroom sign on the ground a few inches from her feet.

(y/n) growled at her viciously, but still did not chew her out.

(y/n) had decided to get as far away from Mabel as she could, and so now she was standing at the base of a redwood tree in the middle of the forest, with a rope attached to a grappling hook in her hand.

There was no way her sister could find her now.

She swung the rope with one hand before letting it go. The grappling hook flew upwards, before wrapping itself around one of the tree's lower branches, even though it was still a few hundred feet above the ground.

(y/n) tugged at the rope, testing its strength, before she strapped the end of the rope to her harness, and started to climb up the tree, clutching to the rope with both hands as she walked with her feet up the tree.

She pulled the rope further through the belay device on the harness every few feet she climbed, so that she wouldn't fall too much if she accidentally slipped or let go of the rope.

Suddenly, Mabel appeared right next to her in the air.

"Hey, (y/n)!" she said cheerfully, before falling back down towards the ground. Mabel landed on the trampoline that she was jumping on at the base of the tree, and then propelled herself upwards again next to her sister.

(y/n)'s eyes widened in shock.

"Mabel!"

The next time Mabel was up in the air again, she had a pair of bright red scissors in one of her hands.

"Don't. You. Dare."

Mabel fell back to the ground, but once she was in the air again, she sliced through the rope with her scissors.

(y/n) screamed as she started to tumble through the air, plummeting rapidly towards the ground. She closed her eyes, preparing herself for the collision, but it never came.

Instead, she found herself submerged in a pool of pink-ish red liquid that she had landed in. She quickly swam upwards and took in a deep breath when she finally reached the surface.

"Mabel! What is this stuff?" exclaimed (y/n), mostly in shock rather than anger.

Mabel had stopped bouncing on the trampoline, and was now standing next to the giant pool, which was about twice her height.

"It's Mabel juice!" she chirped. "It contains plastic dinosaurs, coffee, and red food dye that'll last for at least three days tops!"

"What?!"

Mabel started laughing as she walked off through the forest towards the Mystery Shack.

Meanwhile, (y/n) was taking in rapid haggard breaths as she treaded in the pool, desperately fighting back against her anger that was now threatening to surface. Her deep breathing was turning into frantic panting as she swam out of the Mabel juice, her entire body dyed a slightly red hue.

(y/n) was now walking back to the Mystery Shack rather miserably. She had not been able to get the dye out, so she was still a bright shade of red.

"I'm never going to take a bet with Mabel ever again" she told herself, as she finally reached the Mystery Shack.

However, she was met by a horrific sight that she had not been expecting to see.

A few feet away from the Mystery Shack was her shed, but it was on fire. The flames were roaring higher into the air.

Mabel was standing a distance away, with a box of matches in her hands.

"Oh, hi, (y/n)!" she chirped. "You're back early!"

(y/n) bolted towards the hose, and yanked the dial to the right. She then aimed the hose towards the fire, and water spluttered out of it in a single stream, smothering the flames that were consuming the little shed, and sending smoke up into the air.

When the smoke had finally cleared up, the fire was gone and the shed was still standing, but it was now burnt an ashy black color.

Mabel turned towards her sister to see that she looked like she was on the verge of breaking. She was hunched over in an infuriated position, with her clenched fists trembling in fury, and a crazed look in her eyes that was threatening to boil over.

But suddenly, (y/n) closed her eyes, took in a very deep breath, and after a few seconds finally let it go.

Her shoulders relaxed, her arms rested at her sides, and a serene expression was now in her eyes.

"Nice try, Mabel, but I'm not losing it" she said, her voice strangely perfectly calm. "Until this day ends, nothing in this town is gonna make me lose my temper."

"Hello, (y/n) Pines!" said a new voice, which had a distinct British accent.

(y/n) turned to see Nathaniel, who was walking up to her in his usual confident manner.

She finally snapped.

"NORTHWEST, IF YOU DON'T GET AWAY FROM ME IN THE NEXT THREE SECONDS, I'M GONNA RIP YOUR ARMS OFF AND THEN BEAT YOU WITH THEM!!!!!!!"

Nathaniel's eyes widened in fear, before he turned and bolted away, screaming in terror as an enraged (y/n) was chasing after him, leaving a smug Mabel behind.

She turned towards the abandoned camera with a grin on her face.

"Works every time."
