There have even been a few Gravity Falls concepts around the imagineer forum too!
This one I remember from last year
With the new additions to Disney's Hollywood Studios, a smoother transition from Star Wars to Toy Story would be nice. To make this transition possible, there must be a small area dedicated to an adventure-ish and cartoon-ish IP. And Gravity Falls is the best in the catagory. So expanding to the left of Star Wars and Toy Story (think near Muppets) is the little town of Gravity Falls. And since the land is small, there is one star attraction:
Gravity Falls: Mystery Shack River Tour
The Gravity Falls Mystery Shack River Tour will be a new water attraction to the park. The backstory will be as follows:
A year after the events of Weirdmaggedon, the Pines family returns to Gravity Falls for the Summer. Stan temporarily reclaims the boss position of Mr Mystery and with the help of Ford and the twins capture many of the creatures they came across the Summer before. To take advantage of this, Stan creates a small river attraction and makes Soos the skipper.
And fair warning, this does not follow
EXACT continuity. This is because the continuity can become very difficult to understand if you are not exposed to the show that much, because of the specific events and characters with very specific and developed backstories. So to broaden the mass appeal, the continuity revolving mostly around the final battle and death of Bill Cipher can be slightly ignored.
Queue:
The queue is a scale size of the Mystery Shack. We enter through the front door of the house, towards the backyard leading to the forest. In the living room, we are greeted by Grunkle Stan.
Stan: Hello. Welcome to the Mystery Shack River Tour! I'm Stan, better known as Mr. Mystery! Now, here in Gravity Falls, we have a lot of supernatural, weird, and entertaining creatures. So with the help of my brother Ford, we were able to trap these creatures and display them to the public. Outback, there's a small man made river led by my most faithful employee, Soos. Have fun and remember, we put the fun in no refunds!
Through the house, we proceed outside where the guests load onto the boats led by Soos.
Soos: Welcome to the Mystery Shack River Tour dudes. I'm Soos, the big lovable manchild that's here to show you around, steer your boat, and hoard off the rodents infesting the gnome graveyard exhibit. Uh... Stan said I have to tell you to keep your arms and entire bodies inside the boat at all times, or you will be viciously attacked by a wide variety of monsters and strange creatures.... Oh, and no refunds dudes. Let's get this boat rolling!
(clicks soundboard, followed by explosion sound). Nailed it.
The boat starts off forwards, into the forest where all the exhibits are.
Scene 1:
The boat enters a part of the forest where the gnomes reside. There are trees, gnomes, and small mushroom houses.
Soos: These dudes are the gnomes. They barf rainbows, bathe in squirrels, and don't have a queen right now... hint hint ladies. Oh look, there's Shmebulok!
The bearded, crazed gnome suddenly jerks up and says his favorite and only catchphrase "Shmebulok"
Soos: I.. I think that's all he says. Moving on. Over there's the tavern, the most dangerous eatery this side of the forest. Looks like this little guy had a little too much sap juice. Don't drink too much of that stuff dudes.
The gnome in the window throws up a rainbow.
Soos: Annnnd I'm scared for life. TO THE NEXT EXHIBIT!!!!!
The boat continues down the stream to the next exhibit.
Scene 2
The boat moves to the next exhibit, which is a collection of the more dangerous creatures.
Soos: This is where the most dangerous creatures are. Well, the living ones anyways.
(hits a button on the soundboard, followed by "Suspicion!" in an 80's stereotype male announcer voice)
Soos: But just in case we have Ford monitoring the room with cameras.
Ford (voice only): How ya doing Soos? Hope you're all having fun!
Soos: Smile at the camera, and he'll take the picture. After the ride, you can purchase this for 5, no 10, no 15 dollars! Remember, we put the fun in no refunds. Alright, on your left is the Gremoblin. Normally his eyes would make you see your worst nightmare, but Ford did some creepy magic thing to him.
And on the right is the Shapeshifter. He's frozen right now, because otherwise he could turn into any creature and escape! But we can unfreze him for a second. Look look look dudes
(clicks the freeze/unfreeze button at a very fast rate). Freeze. Unfreeze. Freeze. Unfreeze. Freeze. I think I'll stop there. Moving on.
Scene 3:
The boat appears in a small, circular area, covered with trees, and a giant crystal bunch in the middle.
Soos: And this dudes, is a. Well, I don't know what it is. But I know it grows and shrinks stuff. If you look closely, you cans see a bunch of little and huge animals. Dude in the back, there's a beaver on your shoulder. Let's just take in all the grossly wonderful creatures.
Using some trick projections on screens, you see little eagles, and huge bugs floating by in a truly magical moment.The animals' sounds can be heard as they go about their day and you take in the environment just to be ruined by Soos.
Soos: Okay. I'm bored. Let's go dudes!
The vehicle passes by the shrink/grow crystal and proceeds to the next exhibit.
Scene 4:
The vehicle moves to a swamp like area with some water on each side of the road.
Soos: Now this dudes, is the Gobblewonker exhibit. Now see, the Gobblewonker is like a serpent-dog thingy. There was this funny time where me Dipper and Mabel thought we found him, but it was just a crazy old man bent on world domination or something. If we're really quiet, maybe I can get the Gobblewonker to come out. Here Gobble-gobble-wonker. Here boy. Come out now.
The water starts to ripple. Faster and faster it ripples, small waves start to form. Suddenly, boom! The Gobblewonker pops his head up, hissing and spitting water at the guests. It then moves it's head and wags it's ears like a dog at Soos.
Soos: Who's a good Gobblewonker. Who? Who? Sorry boy, no bones for today. Hey, I'll be back tomorrow.
(whispering) Let's go dudes. He isn't too happy when he wants a bone dudes.
The vehicle continues away from the water to the final exhibit. In the background, you can hear the Gobblewonker howling before going back underwater.
Scene 5:
The vehicle arrives at a small area with missing trees. In the clearing, is the stone body remains of Bill Cipher, still in the ground like he was during Weirdmaggedon. Dipper, Mabel and Mabel waiting for us.
Soos: Oh. Hey dudes! Maybe you could show the tourists the last exhibit.
Stan: Yeah, let the little squirt deal with the money.
Mabel: I think the word your looking for is tourist, Grunkle Stan. Oh well, go Dipper!
Dipper:
(clears his throat) Alright. This hear ladies and gentlemen is a true wonder, one of the greatest achievements of all of mankind...
Mabel: He's obsessed with this thing because Grunkle Ford let him handle it!
Dipper: Shhh! Mabel! Ok, this here, is the body of Bill Cipher.
Mabel: This little demon tried to take over the world. But we beat him with a memory gun, and some prophecy, and a bunch of other stuff I don't really get.
Dipper: Legend has it that after he was trapped in Stan's mind, he was able to escape and still lurks... uh... somewhere.
Stan: Yeah, and apparently if I shake his hand, he like comes back, or something.
Stan goes to shake the statue's hand.
Dipper: Uh, Stan!
Stan: Relax kid. Thing's dead, see?
Bill: Wouldn't be too sure about that Stanley!
Suddenly, the trees turn black and white via projection, with the darker circles turning into eyes. A projection of Bill appears in the statue, and rises (onto a conveniently placed screen in the background).
Bill: Thought you could keep me trapped, didn't you! It's funny how dumb you are! Listen, you thought that Weirdmaggedon was the worst I've got? Even bigger things are coming kids! And one day, you will all bow down to ME!!! Stay uptight Gravity Falls, Bill is ready to GET WEIRD!!! Until then, I'll be watching you!!!
In a flash, Bill disappears. Dipper, looking very worried, begins to speak.
Dipper: Uh Soos, how about we wrap up this tour thing? I need to talk to Ford.
Soos: Uh... Uh... You got it dude.
The vehicle continues to the end.
Soos: And that concludes the Mystery Shack River Tour. Have fun, pray to the owl overlords , and remember, we put the fun in no refunds dudes!
The path takes a turn, back to where the guests get off, and exit through a little bit bigger sized Mystey Shack gift shop.
Lazy Susan's Diner:
In addition to this attraction, Lazy Susan's diner will also make its way to the studios. The restaurant will be a scale representation of the diner from the show.
The menu would feature average items, but with a more emphasis on a small town diner theme. Think sandwiches, hot dogs, burgers, and of course pancakes.
Thank you for reading and I hope you enjoyed this trip north of normal and just west of weird.
