The three are at a table during breakfast.

Mabel is holding a Sir Syrup, when she asks her twin, "Are you ready for the ultimate challenge?"

Dipper is holding a Mountie Man, when he smiles, "I'm always ready!"

Mabel smiled, "Then you know what this means!"

Will watches the twins holding their respective syrup bottles. Mabel wins, but only by cheating.

Dipper picks up and reads the newspaper, "Ho ho, no way! Hey Mabel, check this out."

Mabel looks at ad in newspaper, "Human-sized hamster balls?" She gasps, "I'm human-sized!"

Dipper shakes his head, "No, no, Mabel. This." He points to a monster photo contest ad, "We see weirder stuff than that every day! We didn't get any photos of those gnomes, did we?"

Mabel smiled, "Nope, just memories. And this beard hair."

Will frowned, "Why did you save that?"

"I don't know," Mabel shrugged.

Stan smiled, "Good morning, knuckleheads. You two know what day it is?"

"Um... Happy anniversary?" Dipper guessed.

Mabel shouts, "Mazel tov!"

Stan hits Dipper's head with a newspaper, making Will wince, "It's Family Fun Day, genius! We're cuttin' off work and having one of those, you know, bonding-type deals."

"Grunkle Stan, is this gonna be anything like our last family bonding day?" Dipper asked.

Mabel shuddered, "The county jail was so cold..."

"All right, maybe I haven't been the best summer caretaker. But I swear, today we're gonna have some real family fun. Now who wants to put on some blindfolds and get into my car?" Stan asked.

The twins shout, "YAY!"

"Wait, what?"

Grunkle Stan is driving his car with Dipper and Mabel blindfolded in the backseat, and Will sitting next to him in the passenger seat. Stan leans down to adjust the radio and the tires screech.

Dipper sighs, "Whoa whoa! Blindfolds never lead to anything good."

Mabel gasped, "Wow! I feel like all my other senses are heightened. I can see with my fingers!"

Car jumps, making the twins fly into the doors.

Dipper shouts, "Whoa! Grunkle Stan, are you wearing a blindfold?"

"Ha ha. Nah, but with these cataracts I might as well be. What is that, a woodpecker?" Stan leans forward in an attempt to get a better look at the road in front of him.

Stan drives through a wooden guardrail, making the twins scream.

Dipper and Mabel, still blindfolded, are standing in front of the parked car, which now has branches and sticks caught in the grill.

Stan smiled, "Okay, okay. Open 'em up!"

Dipper and Mabel take the blindfolds off.

Stan grinned, "Ta-da! It's fishin' season!"

"Fishing?" Mabel asked.

Dipper sighs, "What're you playin' at, old man?"

"You're gonna love it! The whole town's out here!" Stan shouts, gesturing to the various townspeople doing different fishing activities.

"Grunkle Stan, why do you wanna bond with us all of a sudden?" Dipper asked in confusion.

Stan laughs, "Come on, this is gonna be great! I've never had fishing buddies before. The guys from the lodge won't go with me: they don't "like" or "trust" me."

Mabel whispers to Dipper, "I think he actually wants to fish with us..."

Stan smiled, "Hey, I know what'll cheer you sad sacks up." He slaps hats on Dipper and Mabel, "Pow! Pines family fishing hats! That-that's hand stitching, you know." The "L" on the "MABEL" hat peels off. "It's just gonna be you, me, and those goofy hats on a boat for ten hours!"

"Ten hours?" Dipper repeated in confusion.

Stan grinned, holding up a book, "I brought the joke book!"

"No! NO!" Dipper yelps.

Mabel frowned, "There has to be a way out of this..."

Old Man McGucket starts shouting," I SEEN IT! I SEEN IT AGAIN! The Gravity Falls Gobblewonker! Come quick before it scrabdoodles away! Eh, eh, ha ha hoo, Ah, hee-hee..."

"Awww... He's doing a happy jig!" Mabel smiled.

McGucket grabs Mabel's shoulders, "NOOO! It's a jig of grave danger!"

"McGucket... let go of her," Will warned.

McGucket shouted, "But I got proof this time, by gummity!"

"Alright... let's see this proof," Will grumbled, slightly annoyed.

McGucket leads them to a ship, "BEHOLD! It's the Gobble-dy-wonker what done did it! It had a long neck like a gee-raffe! And wrinkly skin like...like this gentleman right here!" He points at Stan.

Stan picks his ear, "Huh?"

"It chawed my boat up to smitheroons, and shim-shammed over to Scuttlebutt Island! YOU GOTTA BELIEVE ME!" McGucket shouted.

Sheriff Blubs laughed, "Attention all units! We got ourselves a crazy old man!"

Everyone, but the Pines and the ranger point and laugh at Old Man McGucket. Will just frowns at the word "crazy".

Stan sighed, "Well, that happened. Now let's untie this boat and get out on that lake!" He steps into his rowboat and starts untying it from the dock.

Dipper turns to his sister, "Mabel, did you hear what that old dude said?"

Mabel mimics Old Man McGucket, "Aww, donkey shpittle!"

"The other thing! About the monster! If we can snag a photo of it, we can split the prize fifty-fifty!" Dipper shouted.

Mabel gasps, "That's two fifties!"

"Imagine what you could do with five. Hundred. Dollars!" Dipper grinned.

Mabel smiled, "Dipper, I am one million percent on board with this!"

"One million percent?" Will repeats, looking at the two in disbelief.

Dipper smiled, "Grunkle Stan! Change of plans: we're taking that boat to Scuttlebutt Island, and we're gonna find that Gobblewonker!"

Dipper and Mabel both start cheering, "Monster hunt! Monster hunt!"

"That's not a good idea..." Will admits.

A large honking sound is heard.

Soos pulls up in his boat, "You dudes say somethin' about a monster hunt?"

"Soos!" Mabel shouts.

Will just glares up at Soos, putting his arms against his chest, "No, we didn't."

Soos smiled, "Wassup, hambone!" Soos and Mabel fist bump and make explosion noises, "Dude, you could totally use my boat for your hunt. It's got a steering wheel, chairs; normal boat stuff."

"All right, all right, let's think this through. Ya kids could go waste your time on some epic monster-finding adventure, or you could spend the day learning how to tie knots and skewer worms with your Great Uncle Stan!" Stan smiled.

The twins look at Soos in his boat; he does a robot dance. They look back at Stan in his leaky old boat; he sniffs his left armpit. They look at Will, who just smiles at them. They look at Scuttlebutt Island in the distance. They grin at each other.

Stan sighed, "So, whaddaya say?"

The twins drive off laughing with Soos in his boat toward Scuttlebutt Island, leaving Stan and Will behind.

Mabel laughed, "We made the right choice!"

"Yes!"

Stan scowls, "Ingrates! Aw, who needs 'em? I got a whole box of creepy fishing lures to keep me company... and... you."

"... Sorry, Fez... I'll make sure they don't get into an real trouble," Will mumbled, before running towards the S.S. Cool Dude.

Stan sighs, "At least I have these worms..."

S.S. Cool Dude is headed for the island. Dipper stands on the stern of the boat, with one foot on the guardrail. He adjusts the visor of his cap.

Dipper turned around, "Hoist the anchor!"

Soos pulls up cinderblock anchor.

Dipper shouts, "Raise the flag!"

Mabel held up beach towel, before shouting, "We're gonna find that Gobblewonker!"

"We're gonna win that photo contest!" Dipper shouted.

Soos asked, "Do any of you dudes have sunscreen?"

"We're gonna... go get sunscreen!" Dipper shouted.

Mabel and Soos both cheer, "Yay!"

The boat does a U-turn away from the island. Underwater, a strange shape swims by.

Dipper paces on the boat in front of Mabel, Will, and Soos, "Alright. If we wanna win this contest, we've gotta do it right! Think. What's the number one problem with most monster hunts?"

"You're a side character, then you die within the first five minutes of the movie. Dude, am I a side character?! Do I have to think about stuff like that?" Soos asked.

Dipper shakes his head, "No, no, no. Camera trouble! Say Bigfoot shows up. Soos, be Bigfoot?"

Soos strikes a Bigfoot pose, and Will just glared at him in annoyance.

Dipper faked gasping, "There he is! Bigfoot! Uh-oh, no camera! Oh, wait, here's one! Aw, no film!" Dipper sighed, "You see? You see what I'm, doing here?"

"Oh, yeah. Dude's got a point," Soos nodded.

Dipper smiled, "That's why I bought seventeen disposable cameras! three in my jacket, four for each of you, one extra in this bag, and one... under my hat! There's no way we're gonna miss this. Okay everybody, let's test our cameras out!"

Soos takes a picture of himself, the flash startling him, making him throw the camera overboard, "Aw, dude!"

"You see? This is exactly why you need backup cameras. We still have sixteen!" Dipper smiled.

Mabel throws a camera at a seagull flying over her head, "Ah, bird!"

"Fifteen! Okay, guys, I repeat; don't lose your cameras!" Dipper shouted.

Soos asked, "Wait, lose the cameras?"

"DON'T!" Dipper practically screeched.

Soos shrugged, "Dude, I just threw two away."

"Thirteen! All right! We still have thirteen camera- Twelve. We have twelve cameras," Dipper sighs.

Mabel asked, "So what's the plan? Throw more cameras overboard or what?"

"NO! No. Okay. You'll be lookout, Soos can work the steering wheel, Will can just do nothing, and I'll be captain," Dipper ordered.

Mabel pouts, "What? Why do you get to be captain? What about Mabel, huh?" She starts to chant, "Ma-bel! Ma-bel! Ma-bel! Ma-bel!"

"I'm not sure that's a good idea," Dipper admitted.

Mabel smiled, "What about co-captain?"

"There's no such thing as co-captain," Dipper grumbled.

Mabel grinned, "Aw, whoops." She tosses a camera into the water.

"Okay, fine! You can be co-captain," Dipper grumbled.

Soos asked, "Can I be associate co-captain?"

"As co-captain, I authorize that request," Mabel grinned.

Will scowled, glaring up at Soos, but not saying a word.

Dipper sighed, "Well, as first co-captain, our number one order of business is to lure the monster out with this." He gestures at a barrel of Fish Food.

"Permission to taste some?" Soos asked.

Dipper smiled, "Granted."

"Permission co-granted," Mabel grinned.

Soos smiled, "Permission associate co-granted." He licks some, than gags and wipes his tongue, coughing, "Dude, I don't know what I expected that to taste like!"

Dipper and Mabel start laughing, making Will glare at all three of them.

Dipper sighs, "Oh, Soos..."

Stan watches them, "Traitors! Ah, I'll find my own fishing buddies!" He looks around and sees a couple sitting in a boat up ahead, "Ah!" He starts his boat's engine, "There's my new pals!"

S.S. Cool Dude approaches Scuttlebutt Island. There is fog everywhere. Soos is at the back of the boat shoveling fish food over the side, Dipper and Mabel are at the front, and Will is just sitting by the side. Dipper is trying to see through the fog while Mabel is playing ventriloquist with a pelican.

Mabel smiled, "Hey! How's it going?" She makes a voice for the pelican, "It's going awesome! Bow bow, buh bow bow!"

"Mabel, leave that thing alone," Dipper sighed.

Mabel ends to scaring the pelican away by choking on water and coughing.

"Aren't you supposed to be doing lookout?" Will asked, looking at her.

Mabel shouted, "Look out!" She throws a volley ball at Will, who catches it perfectly, surprising both her and Dipper.

Will just throws it into the water, shaking his head, and sighing.

Mabel laughed, "Heh, heh. But seriously, I'm on it."

The boat jolts to a sudden stop having crashed into the shore of the island.

Mabel smiled, "See? We're here! I'm a lookout genius! Hamster ball, here we come!"

The crew disembarks and ventures into the foggy woods. Dipper leads the group while carrying a lantern. They soon come to a large sign nailed to a tree that says "Scuttlebutt Island." Soos and Mabel stop in front of it.

Soos laughed, "Dude, check it out." He covers the "Scuttle" part of the sign, "Butt Island."

Mabel smiled, "Soos, you rapscallion!" She looks over at Dipper and Will, "Hey! Why aren't you laughing? Are you scared?"

Will laughed, "I've seen worse than this. This is barely scary."

"Pssh! Yeah, right! I'm not-" Dipper doesn't get to finish, as Mabel interrupts him by bopping him on the nose and blowing a raspberry, "-Yeah, you are!"

Dipper scowls, "Hey!" He drops the lantern as Mabel continues poking him and blowing raspberries, "Quit...! Stop! Mabel!"

There's a growling noise in the distance. Mabel stops teasing Dipper and they look around.

Soos comes up to them, "Dude, did you guys hear that?"

A possum grabs lantern and runs away.

Dipper groans, "Our lantern! Aww! I can't see anything!"

"Duuude, I dunno, man. Maybe this, uh... Maybe this isn't worth it," Soos speaks up.

Dipper frowned, "Not worth it? Guys, imagine what would happen if we got that picture!" He smiles, "I'm in!"

Mabel grinned, "Me, too!"

Dipper and Mabel run off.

Soos nods, "All right, dudes, I'm comin'!" He chases them, and Will just sighs, following behind.

Dipper holds a camera, "Guys, guys, guys! You hear something?"

The growling noise from earlier can be heard; a flock of birds flies overhead, away from the sound.

Dipper grins, "This is it! This is it!"

Dipper and Mabel punch each other excitedly and walking towards the sound, "Yes yes yes! Hoo hoo hoo!"

Soos grabs a stick and follows them into the fog, and Will just follows them.

Walking through the fog, Soos stops the group when he spots a lake monster silhouette. The group ducks behind a log.

Dipper smiled, "Everyone: Get your cameras ready!"

Dipper, Mabel, and Soos turn their cameras on.

Dipper smiled, "Ready? GO!"

Soos yells and jumps over the log, holding his camera in front of him as he runs toward the silhouette, snapping photos at random. The twins follow him, but as they get closer, they discover the silhouette was the remains of a wrecked boat with beavers living on it.

Dipper frowned, "But... but what was that noise, then? I heard a monster noise!"

The "monster noise" sounds again. It turns out to be a beaver chewing on, and sometimes activating, a rusty old chainsaw.

Soos grins, "Sweet! Beaver with a chainsaw." He begins to take pictures of it.

"Maybe that old guy was crazy after all..." Dipper sighed.

Mabel nodded, "He did use the word 'scrapdoodle'."

"That... doesnt necessarily make him crazy..." Will whispered.

Soos takes pictures of a beaver posing on a stump, "Ooh, yeah! Work it! Work it! Nice! Nice! Gimme another one of those! Yeah, I like that one."

"What're we gonna say to Grunkle Stan? We ditched him over nothing. Hey... guys, do you feel that? Hey, hey, whoa, whoa!" Dipper yelps.

The Gobblewonker's silhouette is seen swimming away.

Mabel screams.

Dipper shouted, "This is it! Come on! This is our chance! What's wrong with you guys?"

Gobblewonker robot swims back towards the island and begins to rise as the other speak.

Mabel frowned, "Dipper...?"

"Dude...?" Soos started.

Dipper sighed, "It's not that hard, all right? All you gotta do is point, and shoot. Like this!" He aims his camera at Gobblewonker and realizes it's right in front of him.

Gobblewonker robot roars, causing Dipper to drop his camera and all of them to run away.

Soos shouted, "Run!"

The Gobblewonker pushes a tree over which falls and almost hits Dipper and Mabel, but Dipper lunges, and they roll out of the way. The continue to run and dodge falling trees and eventually catch up with Soos.

Soos shouts, "Get back to the boat! HURRY!"

The Gobblewonker snaps at Mabel who hops onto Soos's back.

Dipper aims the camera at Gobblewonker, but trips over a root, stopping the camera, "The picture!"

"Dude, if it makes you feel any better, I got tons of pictures of those beavers, dude!" Soos admitted.

Dipper screams, "WHY WOULD THAT MAKE ME FEEL BETTER?!"

Open with the group running towards the boat. Soos helps the others on, the climbs in himself.

Soos's presence pushes the boat back into the water and he runs towards the helm, "Let's get outta here, dudes!"

They start driving away in the boat backwards.

Dipper sighs, "All right! This is it! Cracked lens! Soos! Get a photo!"

Soos throws cameras at the monster.

"WHAT ARE YOU DOING?!" Dipper screeched.

Soos smiled, "Oh! I still got one left! Don't worry, dude!"

He throws a camera to Dipper but misses hitting the wall and breaking the camera.

The Gobblewonker dives into the water and begins to chase the gang. Soos steers the ship forwards and drives away from it.

Dipper shouted, "Go, go, go, go, go!"

S.S. Cool Dude drives past Stan and soaks him. He throws his hat to the ground in frustration, then sits down and sighs.

Dipper shouts, "SOOS! BEAVERS!"

The boat crashes into the old, broken boat and beavers fly everywhere, biting the boat and the crew.

"Ah, beavers! Oh, no!" Soos shouts.

Beavers are biting Dipper's hat. Mabel shakes a beaver off of her arm, and a beaver lunges at Soos, who stumbles away from the wheel. Will just sighs, glaring at all the beavers, practically daring them to touch him. Mabel takes control on the wheel, steering away from the Gobblewonker. Dipper tries to dislodge a beaver from the side of the boat while Soos runs in circles crying in pain from the beaver still on his face. Dipper throws beavers towards the Gobblewonker who dives and continues to chase them under the water. The S.S. Cool Dude drives through a place with people fishing, who are overturned by the Gobblewonker behind them.

The Gobblewonker swipes at the boat and manages to knock the control cabin off.

Dipper looks around, before he takes out Journals and flips through pages, "Um... uh... GO INTO THE FALLS! I think there might be a cave behind there!"

"MIGHT BE?!" Mabel shouts at him.

Soos, Mabel, and Dipper scream and the boat goes through the waterfall and into cave behind. Their boat crashes, sending them into the dirt. The all stand up, and turn around to see the Gobblewonker swim in after them and get stuck in the cave entrance.

Mabel smiled, "It's stuck!"

"Ha ha! Yeah! Wait...It's stuck?" Dipper asked, before he tries to find a camera, but he has none.

Mabel lifts Dipper's hat to reveal he still has one last camera, "Boop."

Dipper laughs and takes shots of the robot.

"Didja get a good one?" Mabel asked.

Dipper smiled, hugging her, "THEY'RE ALL GOOD ONES!"

"WOO! HAMSTER BALL!" Mabel cheers.

The Gobblewonker, still roaring, gets hit by a rock. It's head falls down with an electric noise.

Dipper frowned, "What the...?" He walksup to the Gobblewonker and touches its side, "Huh?"

"What's wrong?" Mabel asked.

Dipper steps on the gobblewonker and knocks it. It makes a hollow metalic sound. Dipper climbs up the Gobblewonker.

"Careful, Dipper!" Will shouts.

Dipper sighs, "I've got this! Hold on!" He climbs over the Gobblewonker, then pops up from the other side, "Hey, guys! Come check this out!"

The gang discovers a handle and turns it, causing steam to come out. They open the trapdoor causing more steam to come out. They discover old man McGucket inside controlling a machine.

McGucket mumbled, "Work the bellows and the...Eh? Aww, banjo polish!"

"Wha- Yo- You?! You made this? W-w-why?" Dipper asked.

McGucket frowned, "Well, I...I, uh...I just wanted attention."

"I still don't understand," Dipper admitted.

McGucket sighs, "You just don't know the length us old-timers go through for a little quality time with our family."

Will looks down, sniffing.

Dipper and Mabel look at the fishing hats Grunkle Stan gave them and sigh, before looking towards Will.

Soos laughed, "Dude. I guess the real lake monster is you two. Heh, heh! Sorry, that just like-boom-just popped into my head there."

"So, did you ever talk to your son about how you felt?" Mabel asked.

Old Man McGucket shook his head, "No, sir, I got to work straight on the robut! I made lots of robuts in my day! Any of you kids got a screwdriver?

"Well, so much for the photo contest," Dipper takes out his camera.

Mabel smiled, "You still have one roll of film left."

"... and I still have all four of my cameras," Will speaks up.

Dipper looks at the two, "Whaddaya wanna do with it?"

Dipper shouts, "Hey! Over here!" He drives by on the beat-up S.S. Cool Dude and both boats stop before he takes a photo of Stan.

"What the- Kids? I thought you two were off playing "Spin the Bottle" with Soos!" Stan shouted.

Dipper smiled, "Well, we spent all day trying to find a 'legendary' dinosaur."

"But we realized, the only dinosaur we wanna hang out with is right here," Mabel smiled.

Stan frowned, "Save your sympathy! I've been having a great time withoutcha'! Makin' friends, talkin' to my reflection- I had a run-in with the lake police! Guess I gotta wear this ankle bracelet now, so that'll be fun."

"So... I guess there isn't room in that boat for four more?" Dipper asked.

Stan glares at Dipper and Mabel. Dipper and Mabel put on their hats.

Stan sighs, "You knuckleheads ever seen me thread a hook with my eyes closed?"

"Five bucks says you can't do it!" Dipper shouts.

Stan shouts, "You're on!"

Dipper climbs into the Stan O' War.

"Five more bucks says you can't do it with your eyes closed, plus me singing at the top of my lungs!" Mabel grinned.

Stan laughed, "I like those odds!"

Mabel and Soos climb into the Stan O' War.

Dipper smiled, "All right, everybody get together. Say fishing!"

"Fishing!" Mabel and Stan smiled.

Will just glared at all of them a few feet away, shaking his head and ignoring the tears in his eyes.
