Your POV

We were bored out of our minds. The twins and I started searching around for something to entertain ourselves.

Dipper: *opens a closet door* Alright, Grunkle Stan's gotta have some decent boardgames.

You: This is Stan we're talking about.

Dipper: Noted.

Mabel: Let's see! Battle Chutes and Ladder Ships, Necronomiconopoly, Don't wake Stalin,

Dipper: Hey, what's this?!? *picks up a board game* What Could Go Wrong: The Board Game. The last players who opened this box never made it out alive.

You: I don't think I've played that game.

Mabel: Should we play it?

You: *shrug*

Ford: *from another room* Family meeting!!! Family meeting!!!

You, Dipper, and Mabel: *look at each other confused before going the living room*

Ford: Ah, children. Come in, come in. *sits by the table*

Mabel: *as she sits by the table* Ooh, mysterious scrolls and potions!!! Are you going to tell us we're finally of age to go to wizard school?!? Is there an owl in this bag?!? *opens a black bag that's on the table and starts searching through it*

Ford: *snatches the bag away* No! I can assure you if there's an owl in this bag he's long dead.

You: *as you sit next to Mabel with a snicker*

Ford: Now tell me, children, do any of you recognize this symbol? *pulls out a paper with Bill in it*

You, Dipper, and Mabel: *gasp*

Dipper: Bill!

Ford: You- you know him?!?

Dipper: Know him?!? He's been terrorizing us all summer!!! I have so many questions and theories!!!

Mabel: Dipper's been pretty paranoid since Bill turned him into a living sock puppet, and of course he was (y/n)'a boyfriend for like a month.

You: Please don't bring that up...

Dipper: The important thing is: we've defeated him, twice.

Mabel: Once with kittens and once with tickles!!!

Dipper: It was a lot more heroic than it sounds.

Ford: The fact that you've dealt with Bill is gravely serious.

Dipper: So, how do you know Bill?

Ford: I've encountered many dark beings in my time, Dipper. What matters is his powers are growing stronger and if he pulls off his plans no one in this family will be safe.

You, Dipper, and Mabel: *gasp*

Ford: Fortunately there should be a way to shield us from his mental tricks! A way to "Bill Proof" the shack. *pulls out a map of the Mystery Shack* All I have to do is place moonstones here, here, and here. *circles certain areas with a marker* Sprinkle some mercury. Let's see, I always forget the last ingredient. *takes out journal #1, searches a few pages, then groans* Unicorn hair.

You: I've heard about Gravity Falls' unicorns. Isn't getting their hair close to impossible?

Ford: It's hopeless. Unicorns reside deep within the Enchanted Glade. Their hairs can only be obtained by a pure good hearted person who goes on a magical quest to find them.

Mabel: *yells in excitement* Grunkle Ford, can I please go on this quest?!? I am literally obsessed with unicorns!!! My first word was unicorn, I once made my own unicorn by taping a traffic cone to a horse's head, are you even looking at the sweater I'm wearing right now?!?!?!? Not to mention that I'm probably the most pure hearted person in this room.

Ford: That's true. She's got a point.

Dipper: Right, can't argue with that.

Mabel: So can I go on a mission to get that hair?!? Please please please?!? I'll give you my blood!!!

Ford: Very well.

Mabel: YES!!!! And (y/n), you'll be joining me!!!

You: Eh?

Ford: But it won't be easy. Take this. *gives Mabel his journal* And this. *gives Mabel a crossbow*

Mabel: Ooooh!!!

Ford: I haven't been in this dimension for a while. It's ok to give children weapons, right?

Mabel: Psh, c'mon, dawg. *accidentally shoots an arrow out the window*

Stan: *outside* AH, IT'S THE COPS, GUN IT!!!

Mabel: ... *takes her phone and calls people* Candy, Grenda, Wendy!!! Clear the afternoon!!! *grabs your wrist and runs off*

Dipper's POV

Dipper: So what are the odds she gets that hair?

Ford: If I had to describe unicorns in one word it would be: frustrating...

Dipper: So what are we gonna do about Bill?!?

Ford: Follow me.

Ford takes me down to a secret room bellow the shack, but above the portal bunker.

Ford: Welcome to my private study, a place where I keep my most ancient and secret knowledge. Even your uncle Stan doesn't know about this place.

Dipper: *follows Ford near some monitors*

Ford: If we can't "Bill Proof" the shack, we'll have to do the next best thing: *takes out a strange devise* we're gonna have to "Bill Proof" our minds.

Ford put the strange device on my head which was now tightly secured, and beeps began coming from the computer.

Dipper: So what is Bill exactly?

Ford: I don't know, nobody does. Accounts differ of his true origins.

Dipper: *takes a file and starts looking through it*

Ford: I know he's older than our galaxy and far more twisted. He doesn't have physical form, he can only project himself into the thoughts of mortals through the mindscape. And that is why he wants this. *shows you and Dipper a weird galaxy looking snow globe*

Dipper: What is that...?!?

Ford: A tear in our dimension...!!! I dismantled the portal, but with this tear Bill still has a way into our reality. To get his hands on this rift, Bill would trick or posses anyone.

Dipper: So how do we keep Bill out of our minds?

Ford: Well there's a number of ways. I personally had a metal plate installed in my head.

Dipper: *laughs awkwardly* Good one.

Ford: *bangs his head making metallic sound*

Dipper: ...

Ford: But this machine is safer. It will scan your mind, bio-electrically encrypting your thoughts so Bill can't read them. Now, say hello to your thoughts.

"Oh man, I can't believe I'm with the author!!!"

"Is my fly down?"

"DISCO GIRL!!!"

"COMING THROUGH!!!"

"(y/n) (y/n) (y/n) (y/n)"

Dipper: Uh- might wanna... ignore that last one.... So anyways, what's your deal with Bill?

Ford: Dipper, do you trust me?

Dipper: Well yeah, but-

Ford: Then you'll trust that that's not important. Now focus, it's time to strengthen your mind.

Your POV

We picked up Candy, Grenda, and Wendy and started our journey. On the way...

Mabel: It's not to finally be out on a mission just us gals.

Grenda: Forget the gal talk, I'm here to meet to touch and/or become a unicorn!

Candy: I hear if you lick a unicorn's neck it tastes like your favorite flavor in the world!

Mabel: Candy, I will make sure you lick that unicorn's neck because I care about my friends!

Wendy: Honesty I stopped believing in unicorns when when I was like five years old. I'm just coming along to keep you kids from walking into a bear trap.

You: I'm here because Mabel forced me.

Mabel: Stop!!! This is the magic part of the forest!!! *looks at a page in the journal* Let's see. The gnome tavern is over there, the fairy nail salon is over there, but it says to summon the unicorn one must fellow this ancient chant droned only by the deepest voiced druids of old.

Grenda: On it!!! *grabs the journal and goes to the center of the area, then clears her throat and starts doing some weird sounds*

Wendy: I bet you ten bucks nothing happens.

Mabel: I'll take that bet.

Just then the ground started to shake and a building started rising from the ground. We all stare in awe before opening the gigantic golden doors. We let out a gasp as we see a beautiful unicorn sitting on a rock surrounded by water as she swayed her main around.

Grenda: Mother of mother!!!

Candy: Queen of dreams!!!

You: Oh my gosh...!!!

Wendy: No way...!!!

Mabel: *reaching out to Wendy* Eh eh.

Wendy: *gives Mabel a ten dollar bill as she sighs in frustration*

Unicorn: Hark! Visitors to my realm of enchantment!

Mabel: *gasp*

Candy: *gasp*

Grenda: *gasps but swallows a butterfly and chokes*

Mabel: Oh my gosh oh my gosh!!! What's your name?!?

Unicorn: I am Celestabellebethabelle, last of my kind. Come in, come in. Just take off your shoes, I have a whole thing about shoes.

You, Mabel, Candy, and Grenda: *take off your shoes*

Girls: *start going near Celestabellebethabelle*

Celestabellebethabelle: Ah-ah! I'm talking to all of you.

Wendy: *takes off her boots in frustration and follows you all*

Mabel: Celestabellebethabelle, we have journeyed far and wide-!!!

Grenda: About an hour!!!

Mabel: On a mission to protect our family with your magical hair!!!

Candy: *next to Celestabellebethabelle, whispers* This is your chance, Candy. Lick the neck. *goes to lick the neck* Lick it...!!!

Celestabellebethabelle: Very well, to receive a lock of my enchanted hair, step forward girl of pure perfect heart!

You, Candy, Grenda, and Mabel: *nod at Mabel*

Mabel: *smiles* Presenting!!! Pu-pu-ru-ru-pu-pa-pu-pa!!! Mabel!!!

Celestabellebethabelle: What?!? You?!?

Mabel: *her expression falls a bit*

Celestabellebethabelle: A unicorn can see deep inside your heart, child!!! *uses her horn to make a heart shape appear in Mabel's sweater*

Mabel: Ug! *covers her sweater*

Celestabellebethabelle: You have done wrong!!! Wrong I say!!!

Mabel: I guess I do make fun of Dipper a lot... And I did just shot a window with a crossbow...

Celestabellebethabelle: Your bad deeds make me cry! *a tear falls down on a flower which kills it*

Mabel: No!!!!

Celestabellebethabelle: Come back when you're... pure of heart!!! *neighs* ... Exit is that way.

Girls: *exit the building*

Celestabellebethabelle: Shoes, shoes, take your shoes. This isn't some... shoe store.

You: Hey, M, don't let her get to you!

Wendy: Yeah, I wouldn't trust a horse that wears makeup.

Mabel: No, girls, she's right. I used to be one of the sweetest people I knew! But recently I've been slacking in the whole goodness department. Well, today we're gonna fix it! From this moment forth, I'm gonna do so many good deeds and I'll have the purest heart in all of Gravity Falls!!! *raises her arm and accidentally punches a flying by bird* ... that- that bird is fine.

Dipper's POV

The process took a lot longer than I thought. By the time it had reached 15%, Ford had fallen asleep. I was starting to get irritated, how long had I been doing this for?!?

I looked over at my sleeping uncle. Why did he have to be so mysterious about Bill? I could handle the truth.

"I wonder what great uncle Ford is thinking."

"Use the machine!"

"It'll show you his thoughts!"

Dipper: I-I shouldn't...

"He won't know."

"He's going to tell you eventually."

"The more you know about Bill, the more you can help!"

Dipper: Man, I am really good at rationalizing!

"Yes you are!"

"Yes you are!"

"Yes you are!"

"Yes you are!"

With that, I took the strange metal devise off my head and placed it on Ford's. It was just on little peek, what was he hiding about Bill...?

First was Bill cackling.

"Where are these ideas coming from?!? Who are you working with?!?"- Fiddleford.

"My brother is a dangerous know-it-all."- Stan.

"He would trick or posses anyone!" -Ford

"Then it's a deal. From now until the end of time." -Younger Ford.

"Just let me into your mind, Stanford!" -Bill.

"Please, call me a friend." -Younger Ford.

The last thing was Bill possessing Ford as he cackled evilly.

Now way...

Ford and Bill?!?

Ford: *stands up, his glasses blurry, not able to see his eyes* You shouldn't have done that. *takes off the strange devise and throws it, revealing many things with Bill*

Dipper: *gasp*

...

Dipper: Why- why were you shaking hands with Bill?!? *takes the rift* You said Bill could possess anyone to get this!!! AH-! *almost drops the orb*

Ford: Careful!!!

Dipper: !!!

Ford: Hand me the rift. Now, boy!!!

Dipper: Why were you really scanning my thoughts?!? *takes a nearby memory gun* Are you Bill right now?!?

Ford: *starts walking forward making Dipper walk back in fear* Now just-!!! Just calm down, p-...

Dipper: PINETREE?!? Is that what you were going it call me?!?

Ford: I was gonna say please, kid!!!

Dipper: Great uncle Ford told us to protect the rift!!! Get one step closer and I'll shoot!!! I'll erase you right out of Ford's head!!!

Ford: It's me, Dipper, it's your uncle!!!

Dipper: Trust no one.., Trust no one...! Trust now one...!!!

Ford: JUST HAND IT TO ME!!! *reaches for them*

Dipper: *shuts his eyes close, his hands shaking, but shoots the ray at Ford, which bounces against him and around the room, disappearing when hitting a monitor*

Dipper: ...

Ford: *picks up Dipper by his vest*

Dipper: HEY!!! LET GO OF ME!!!

Ford: Now now, just calm down, calm down! *fixes his glasses, revealing his eyes* Look into my eyes! Look at my pupils! It's me, Dipper! It's me...! *smiles warmly*

Dipper: *sigh* ...

Ford: *places him down*

Dipper: I tried to erase your mind... I'm so sorry...

Ford: It's ok, Dipper. Besides, my mind can't be erased anyway, remember? *hits his head making a metallic sound* If that really was Bill though, you would've done great! I should've been more like you when I was young... Dipper, I was a fool to try to hide all this... The reason I've been trying to prepare you for Bill's tricks is because Bill tricked me... It's the biggest regret of my life... Bill wasn't always my enemy, Dipper... I use to think he was my friends...

I'm not writing all the explanation
~skip brought to you by chocolate and coffee~

Ford: To Bill, it's just a game, but to us... it would mean the end of our world as we know it...

Dipper: Oh man...

Ford: 'Oh man' indeed...

Your POV

We spend hours helping Mabel do some good deeds, although I think instead of helping she only worsened their situations... By the end of the day we had a thousand good deeds and made our way back to Celestabellebethabelle's home.

Celestabellebethabelle: Not pure of heart!

Mabel: Boo-ya!!! Wait, what?

Wendy: How is that even possible?!? Mabel's a straight up saint, you judgmental hoofbag!!! 

Mabel: *kneels down* Please, tell me what I'm doing wrong!!!

Celestabellebethabelle: Doing good deeds to make yourself look better isn't good at all!!! Not to mention you're crushing like ten dandelions right now! Those are basically children's dreams.

Mabel: *stands up looking at herself and gasping*

Celestabellebethabelle: I'm sorry, Mabel, it's not my fault your a bad person.

You, Candy, Grenda, and Wendy: *gasp*

Mabel: *runs away crying*

You: No, Mabel!!!

Wendy: Come back!!!

Celestabellebethabelle: Now if you'll excuse me, I have a 3:00 posing in front of a rainbow. *goes to the water fall and neighs*

We all followed Mabel and found her by the stream wrapped in herself.

Wendy: C'mon, Mabel, don't beat yourself up over this.

Candy: Let's forget about getting that dumb unicorn hair.

Mabel: It's not about the hair anymore, guys, it's about me. Being kind and sweet is what makes me who I am, but if I'm not a good person who am I...? *takes out a tiny notebook and a pen* I'm not leaving this spot until I think of a deed that makes me as good as Celestabellebethabelle.

You: But M-!

Mabel: Just leave me be! *turns around and starts to write*

Wendy: Psst. *nods with her eyes to follow her, then walks further from Mabel as you, Candy, and Grenda follow her* Guys, if you ask me, this whole thing is a serious load! Mabel's like the best person I've ever met! We tried getting that hair the good way, now it's time we try the Wendy way.

Grenda: Are you suggesting violence? Sabotage?

Candy: Mabel's not going to like that...

Wendy: Mabel doesn't need to know. Look, it's time we stop trying to be so perfect and be who were really are! We're crazed angry sweaty animals!!! We're not unicorns, we're women!!! And WE TAKE WHAT WE WANT!!! *punches a tree*

Candy and Grenda: *cheer*

Grenda: *breaks a boulder with her skull* ... too much?

Wendy: You in?!?

You: *sigh* What the heck, sure.

Wendy: Here's the plan.

We broke into some gnome bar. Wendy broke down the door which startled all the gnomes.

Wendy: I'm looking for someone who knows how to take down a unicorn!!! No tricks or games!!!

Candy: We are humans, we take what we want!!! *breaks a bottle*

Grenda: Yeah!!!

Mysterious Gnome: Fairy dust. A whole magic bag's enough to put a unicorn out cold, but if I do you a favor, you gotta do something for me.

You: Spill it.

Mysterious Gnome: Butterfly trafficking is illegal in this part of the forest. But I like the butterflies, they tickle my face and make me laugh. Bring me a bag of butterflies and we got a deal.

After getting the butterflies we hid behind some bushes as Grenda went over. After they traded bags the gnome police came and we went out of hiding. We snuck passed Mabel and went to Celestabellebethabelle's home. She was reading some book when we threw the fairy dust knocking her unconscious. Grenda took care of the small fawn. Wendy took some scissors and was about to cut Celestabellebethabelle's main when Mabel came bursting through the door.

Mabel: No wait!!!! Stop!!!!

Wendy: *whispers* Mabel, shh! You'll wake her up!

Mabel: *takes away the scissors* But this is wrong, guys!!!

Wendy: But protecting the shack is good!!!

Celestabellebethabelle: *wakes up and sees Mabel holding the scissors* What?!? Don't my eyes deceive me?!? Thief!!! You shall never be pure of heart!!!

Mabel: No, you don't understand!!! You just wanna be good like you!!!

Voice: Whoa whoa whoa, you gotta be kidding me!

Mabel: Huh?

Blue and Pink Unicorns: *enter*

Blue Unicorn: Yo, C-Beth, are you seriously pulling this pure of heart scam again?!?

Pink Unicorn: That is messed up, man.

Mabel: Wait, scam?

Pink Unicorn: Kid, unicorns can't see into your heart. All our dumb horns can do is glow, point towards the nearest rainbow, and play rave music. *starts to play some rave music before he stops*

Blue Unicorn: Yeah, the whole "pure of heart" racket is just a line we use to get humans to leave us alone.

Celestabellebethabelle: Guys... shut up...

Mabel: *starts shaking in anger* All this time... All this time I thought I was a bad person...!!! But you're even worse than I am!!!!!!

You, Candy, Grenda, and Wendy: *gasp*

Celestabellebethabelle: Ok fine, so you learned our secret, we're jerks, ok? We have more hair than we know what to do with, and we keep it to ourselves just to tick humans off. What are you gonna do about it, huh? Huh?!? What are you gonna do~?!?

Mabel: *punches Celestabellebethabelle's face*

You, Candy, Grenda, and Wendy: *gasp*

Wendy: Woooooo, go, Mabel!!!

Grenda: Join the dark side!!!

Mabel: *rips off the unicorn design on her sweater*

You, Candy, Grenda, and Wendy: Fight!!! Fight!!! Fight!!!

Celestabellebethabelle: *wipes off the rainbow stains off her face* Oh, so it's a fight you want, well, then it's a fight you're gonna get!!!

Dipper's POV

After that, we went upstairs and got some Pit Cola.

Dipper: *sigh* I'm so embarrassed about earlier... I'm such an idiot...!

Ford: From now on, no more secrets between us. We're not the first two idiots to be tricked by Bill, boy, but if we work together, it could be the last.

Dipper: I hope you're right...

Ford: However, Dipper, there's something we need to make this work.

Dipper: What is it?

Ford: Well, more of a someone.

Dipper: Huh?

Ford: Your friend (y/n), she can be of great help to us.

Dipper: Well, she is really smart, but-

Ford: I don't mean intelligence, Dipper. There's something different about her, something inhuman.

Dipper: *his eyes widen a bit* What...?!?

Ford: She has an energy that I've sensed somewhere before while I was stuck in dimensions, with it, we can definitely defeat Bill once and for all.

Dipper: ... I... I don't know... She won't get hurt, will she...?

Ford: I'm 98 percent certain it won't harm her.

Dipper: Then how exactly do we use the energy?

Mabel: *places unicorn hair on the table* Did someone say unicorn hair?!?!?!?

...

Dipper: Uh, no actually...?

Mabel: Oh. That would've been perfect! Either way we got some unicorn hair!!!

Candy: Also some unicorn tears, unicorn eyelashes,

Grenda: They finally gave us this treasure just to get rid of us!!! *opens the treasure chest making gold and jewels fall on the table*

Ford: *stares at the gold in awe* It- It can't be! This is a great day, girls!!! With this unicorn hair we'll be able to completely shield the shack from Bill's mind reading tricks!!!

Mabel: Is it ok?

Ford: Better than ok, it's perfect!!! You've protected your family, you're a good person, Mabel!

Mabel: Thanks, Grunkle Ford, but today I learned that morality is relative.

Stan: *runs in and grabs all the gold and jewels* MONEY!!! *runs away*

I looked over at (y/n). I remembered back in the museum when the memory ray didn't affect her at all, which was more than strange since it affected everyone else like it was suppose to.

Maybe...

Maybe Ford was right...

Maybe she's not completely human...

Thanks for reading!!! 'Till next time!!!

❤️❤️❤️
