Here's the 7th script, the Christmas special:
A snowy day at the Mystery Shack.
Dipper: I can’t believe mom and dad shipped us back to Gravity Falls for Christmas! Why did they have to be busy during Christmas break?
Mabel: Well, I think the forest looks so pretty covered with snow. Plus this Santa hat I found looks so cute (motion to the red and white hat she’s wearing).
Dipper: It is cute, but I’m still not looking forward to Christmas.
Mabel: Oh, come on! I’m sure there’s something you’re looking forward to.
Dipper: Not a thing.
Mabel: Just one thing?
Mabel: What about the Mystery Shack Christmas party?
Dipper: What party?
Mabel: Stan told us about it the other day. Oh yeah, you were staring at Wendy the whole time.
Dipper: I was?
Dipper: Not looking forward to it.
Mabel: What about the snow?
Dipper: No, it’s too cold.
Mabel: Wait, I have an idea! Can I at least show you how pretty the snow looks in the forest?
So they bundle up in winter clothes and head outside.
Mabel: Is it looking pretty yet?
Dipper: Maybe a little.
Mabel: Whoa! Look at that tree! The branches are arranged like stairs! I’m gonna climb it.
Dipper: i thought you were afraid of heights.
Mabel: Not if i'm not looking down.
Dipper: I’m not sure that’s a good idea…
Mabel: Hey look! I’m almost at the top! Whoa, this branch is icy. I hope it don’t sli- Ahhhhh! *thud*
Dipper: Mabel! Are you okay?
Mabel: I feel…dizzy.
Dipper: This is all my fault. I shouldn’t have said snow is boring. Then we would have never come out here, and this would’ve never happened.
Mabel: No, it’s my fault. I should’ve listened when you said don’t climb the tree.
Dipper: Are you sure you’re okay?
Mabel stands up and then a large branch from the tree snaps and falls on her foot.
Mabel: Ow! Ok, now I’m not okay.
Dipper: Did you bring your cell phone? I’ll call Stan to pick us up.
Mabel: It’s in my pocket. Glad it’s waterproof.
About an hour later:
Dipper: Man, it’s been an hour and no one’s here yet.
Mabel: Yeah, and I’m getting cold.
Dipper: So am I.
Just then, they hear a sound coming towards them.
Mabel: What’s that?
Dipper: I have no idea.
Just then the Mystery Shack golf cart comes into view, with Stan driving.
Dipper: What took so long?
Stan: This thing only goes like 2 miles an hour in the snow.
Mabel: Can we go yet? It’s freezing out here.
About 2 hours later, they had just pulled up to the Mystery Shack.
Dipper: What took so long that time?
Stan: It was snowing hard the entire time.
Once they’ve all gotten inside, Dipper and Mabel warm up with hot chocolate.
Mabel: I’m still cold.
Dipper: I’m getting warmer.
Mabel: I still don’t get why Stan doesn’t put any Christmas decorations up.
Dipper: I know. Hey, I bet they’re down in the basement. Wanna look?
Mabel: I would, but my foot is killing me.
Dipper: Oh, right. Maybe later.
Mabel: This is boring.
Dipper: I know. Want to play a board game?
Dipper: I’ll get one.
Wendy walks in.
Wendy: Hey. How’s your foot?
Mabel: Bruised and possibly broken.
Wendy: A similar thing happened to me. My brothers were trying out their rock slingshot. Shot a rock right into my foot, and I couldn’t walk for a week!
Mabel: That’s not helping.
Wendy: Sorry. I think Stan’s calling me. I’ll be back later.
Wendy leaves just as Dipper walks in with a board game.
Dipper: Hi Wendy!
Dipper: You ready to play?
Mabel: Any time!
That evening, the twins headed to the basement to find some decorations.
Mabel: Found them!
Dipper: Whoa! Stan has so many decorations!
Mabel: I wonder why he didn’t put any of them up. Christmas is in three days!
Dipper: Well, I guess we can take some of these upstairs.
Mabel: Hey look at me! I’m balancing a box on my head! I wonder if I can carry it upstairs like this.
Mabel trips and drops the box, spilling all the contents, including a paper in the bottom.
Dipper: Look at this paper! It looks like it was torn out of a journal or something.
Mabel: It says the Christmas curse at the top.
Dipper: This looks like Stan’s writing.
Mabel: Well, read it!
Dipper: Okay, okay! December 23, 1990. Dear Diary, You’ll never-
Mabel: Stan had a diary?
Dipper: Can I finish?
Dipper: You’ll never believe what happened today. This wizard guy came by the shack and asked if he could have a free replacement of a broken product. I said no, so he put a curse on me and the Mystery Shack. The curse was that if ever tried to celebrate Christmas here again, the Mystery Shack would be destroyed. I was allowed to have a Christmas party on Christmas Eve, and everything must disappear afterwards.
Mabel: So that’s why there are no decorations up!
Dipper: Maybe we shouldn’t risk it.
Mabel: How do we know that the curse is even real?
Dipper: Read this. (picks up another sheet of paper)
Mabel: December 30, 1991. Dear diary, at first I thought the curse was fake. Turns out, its real! I put up decorations anyway, and on Christmas a huge wildfire that was in the woods came less than 20 feet from the Mystery Shack. Luckily, the firefighters put it out.
Mabel: Wildfires happen all the time. I’m sure it was just a coincidence.
Dipper: There’s one thing wrong with that theory. It was the middle of winter, so the trees couldn’t catch fire because of the snow.
Mabel: Oh. That makes sense.
Dipper: Now do you see why we shouldn’t put up decorations?
Mabel: Well, how do you know the curse is still working?
Dipper: I don’t.
Mabel: So why can’t we at least try to put up decorations?
Dipper: Maybe you’re right. Let’s take these upstairs.
So they carry the boxes upstairs, and the next morning they start putting them up. Mabel puts on a Christmas music CD for background music.
Dipper: Wow! This looks great!
Mabel: I know, right?
Wendy: Whoa! Did you two do all this?
Mabel: Yeah! Do you like it?
Wendy: It looks awesome.
Dipper: Wanna help us with the rest of the decorations?
Soos walks in.
Soos: Dudes, this looks so cool!
Mabel: Want to help us put up decorations?
After about 3 hours, everything was decorated.
Wendy: This looks so cool!
Just then, Stan walks in.
Stan: What did you do!?
Mabel: We put up the Christmas decorations we found in the basement.
Stan: By any chance did you find some papers in one of those boxes?
Dipper: Yeah, why?
Stan: Because the curse is still on the Mystery Shack!
Soos: That’s why you don’t put up any decorations!
Wendy: I thought you were just crazy.
Stan: There’s a reason! Well, I wonder what will happen this time. Fire, earthquake, volcano?
Dipper: We just thought it was fake.
Stan: Why would you think that?
Mabel: Do real curses even exist?
Stan: Yes! Now take down the decorations.
Dipper: we worked 4 hours putting those up!
Mabel: If you take them down, then I’ll put your most embarrassing secrets online!
Stan: How do you know my secrets?
Mabel: You should stop hiding your personal things in the basement.
Stan: You found the box, didn’t you?
Mabel: Yeah, and I would love to put some of those pictures online!
Dipper: When did you find that?
Mabel: I have a lot of free time.
Stan: Okay! You can leave the decorations up! But don’t say I didn’t warn you.
The next day they are setting up for the Christmas party.
Dipper: Well, that didn’t take long.
Mabel: I know. And it only took an hour!
Dipper: I hope this party is nothing like the last one. I’m not making that mistake twice.
Mabel: That was a crazy night. But this time, I’m so winning that party award!
Dipper: Are we even doing awards this year?
Mabel: I’m not sure. Hey look! It’s snowing!
Dipper: It’s snowing really hard! I hope this won’t affect the party tonight.
About 2 hours later, there was nearly 2 feet of snow.
Mabel: That’s a lot of snow!
Stan: I’m calling off the party. There’s too much snow and it keeps coming!
Dipper: There’s nothing we can do, Mabel.
Mabel: But this was supposed to be the best Christmas ever, starting with the party!
Dipper: We can’t stop the snow.
Mabel: I- I understand. Well, can we at least go out in the snow?
Stan: Probably not a good idea. There’s like, 3 feet of snow. It’s coming down so hard I can’t even see my car from the window.
Dipper: Want to go watch TV?
Just then the lights flicker and go out.
Dipper: Come on! Really!?
Mabel: Maybe this won’t be the perfect Christmas.
The next evening, Christmas eve.
Mabel: Yay! Christmas is tomorrow!
Dipper: I know. But have you seen the snow? It’s been snowing for almost a day straight.
Mabel: Cool! There must be 4 feet of snow out there!
The next morning, Christmas morning, at about 7 a.m.
Mabel: Dipper! Wake up! It’s Christmas!
Dipper: Do we really have to get up this early?
Mabel: Yes! Come on, let’s go downstairs!
Dipper: Okay, okay! I’m coming!
They run downstairs to see a pile of presents. Stan, Wendy, and Soos are standing nearby, stacking more on the pile!
Mabel: Ooh! Presents!
Wendy: Do you think we bought enough?
Dipper: Wait, you guys bought all these?
Stan: Well, we decided to make this a big, fancy Christmas morning because we haven’t celebrated in so long.
Mabel: What are we waiting for? Let’s open these! (dives face-first into the pile) Ow. Hey! I totally wanted this!
After nearly an hour of opening gifts, there’s a large pile of wrapping paper and presents everywhere.
Dipper: So, I guess there’s no curse after all!
Mabel: Guess so.
