In the morning at the Mystery Shack, the triplets, and their cousins, Andrew, and Gary sat in the kitchen eating breakfast though the triplets themselves were doing some sort of competition, and the brothers seemed to be entertained by what was happening.

"Welcome one and all to the one, the only syrup racing competition!" Mira said with enthusiasm, "In the right corner, we have contestant Mabel Pines ready to take down the competition and on the left contestant number two, Dipper Pines, prepared blow his opponent's mind away! Ready your bottles!"

Mabel and Dipper both had a competitive look on their faces. "Are you ready for the ultimate challenge?" Mabel said holding a syrup bottle that was labeled Sir Syrup.

"I'm always ready!" Dipper said holding a bottle labeled Mountie Man.

"Ready… Set…" Mira said, holding up her hand, before slamming it on the table, "RACE!" Dipper and Mabel flipped the bottles upside down and the syrups had slowing started to drip out of the bottle and onto to their mouths.

"Go Sir Syrup!" Mabel cheered having her mouth wide open.

"Go Mountie Man!" Dipper said his mouth wide open as well.

"Go, go, go!" Mira chanted.

"Come on Mountie Man! I believe!" Gary said.

"Money's on you Sir Syrup!" Andrew cheered on.

The syrup on Sir Syrup had gotten closer and closer to Mabel's mouth as was Dipper's Mountie Man. "Almost… Almost…" Mabel said. She tapped on the end of the bottle and the syrup landed in her mouth. Mira cheered while Gary groaned while Andrew cheered for victory.

"We have a winner! The crowd goes wild!" Mira said lifting Mabel's hand in the air; Mira mimicked the cheer of a crowd. While Andrew and Gary clapped for Mabel.

"Thank you! Thank you!" Mabel said before she started to cough.

Dipper sighed but smiled; he placed the syrup down and looked at the newspaper that sat beside him. A certain ad had caught his eye. "Whoa guys take a look at this." Dipper said showing it to his sisters and Gary.

"Wow…" Mira said looking at the same ad that Dipper was looking at.

"No way…" Gary said looking astonished.

Andrew looked over the paper, "Oh, seriously, they're having that now?"

Mabel looked over Dipper's shoulder and saw an ad that had read-

"A human sized hamster ball?" Mabel read before gasping, "I'm human sized!"

"Umm, Mabel, the ad we're looking at is on the next page." Mira said pointing to what Dipper was showing. Mabel looked over at the next page. The page had read a Monster Photo competition; Win $1000. On the picture it had showed last month winner.

"We see weirder stuff than that everyday." Dipper said.

"We didn't get any photos of those gnome guys didn't we?" Gary asked.

"Nope, just memories!" Mabel said, "And this beard hair!"

She held up a piece of beard hair from one of the gnomes. Mira looked at it and couldn't help but shiver, "Why do you have that?" Mira asked, "How do you have that?"

All Mabel did was shrug in reply and she put the beard back in her pocket.

"What was that about gnomes?" Andrew asked.

Skyla and Stan had soon entered the kitchen. "Morning boys." Skyla said planting a kiss on top of her sons head. "Hey you knuckleheads." Stan said, patting his two nieces and nephew on the head, "Guess what today is?"

"Umm… Happy anniversary?" Dipper said.

"Mazel tov!" Mabel said.

"Happy birthday?" Mira said.

"Thanksgiving?" Gary suggested.

"We're not in fall yet little bro." Andrew said.

Stan hit them all on the head with a rolled up newspaper. "It's family fun day geniuses." Stan said, before getting something from the fridge.

"Family fun day?" Mira said.

"That's right." Skyla said, "We're going to be taking some time off of work to have some good old fashioned family bonding. Dad and I already have something planned for all of you today."

Everyone seemed to be excited about this; All except Dipper who seemed a bit skeptical about it. "Just to check, it's not gonna be like the last family fun day is it?" Dipper asked.

-Last Family Fun Day-

Dipper, Mabel and Mira were currently making some counterfeit bills for Stan to use. Stan looked at the their progress, "You call that Ben Franklin?" He said, "He looks like a girl!" They soon stopped everything when they heard sirens just outside.

"Uh-oh."

-Back to the Present-

Mabel couldn't help but shiver when she thought back to what happened. "That county jail was so cold." Mabel said. "And creepy…" Mira said shivering as well.

"Okay, okay, I'll be the first to admit, that my dad isn't really the best summer caretaker." Skyla said, "But he planned this day all himself, so it's going to be a fun day for all of us."

"Sky is right, you can trust me with today." Stan said to his nieces and nephew, "Now who wants to put on my blindfold and get into my car?!"

"Yay!" The three triplets said. Though Mira had a quizzical look on her face, "Wait a minute blindfolds?"

-Later in Stan's Car-

Dipper, Mabel and Mira sat in the backseat of Stan's car, since Skyla and Stan had decided to drive separately. Though Skyla didn't think it was good idea, but Stan had just insisted. The triplets sat down in the backseat with blindfolds tied over their eyes. They felt the car's twist and turns, and despite having their seat belts on they felt themselves wobble back and forth as the car drove.

"If there's anything that movies taught us, blindfolds never lead to a good thing." Dipper said.

Mabel was feeling excited about it though, "Wow, I feel like my other senses are heightened." Mabel felt Mira's face who sat in between Dipper and Mabel; she giggled and laughed. "Pass on!" Mira said feeling Dipper's face; he couldn't help but laugh.

Though they suddenly jumped when the car had gone over a bump.

"Your not wearing a blindfold too are you Grunkle Stan?" Mira asked.

Stan laughed at that, "Nah, but with these cataracts I might as well be." He squinted just ahead of what was in front of him, "What is that a woodpecker?" They all screamed as they drove through a fence and the forest.

-Later-

Stan had helped the three kids out of the car. Skyla couldn't but groan when she saw the damage on her father's car. The triplets and her sons stood there frozen wondering where they were exactly.

"Okay, you can remove the blindfolds now." They heard Skyla say.

They removed the blindfolds and they found themselves at the lake with the sign that had said Fishing' Season on the top.

"TA-DA!" Skyla and Stan both said.

"Fishing season?" Mira asked.

"We're gonna go fishin!" Gary said with excitement.

"What are you playing at old man?" Dipper said eyeing Stan.

"No tricks." Stan said to his nieces and nephew, "You kids are gonna love it! The whole town is out here!" The triplets looked around and saw the whole town out there as Stan had said. There was Lazy Susan, Toby Determined and Manly Dan, Wendy's dad who was currently beating up a fish that one of his son's had caught.

"Now that's some family bonding!" Stan said with a smile.

"Grunkle Stan, no offense, but how come you wanna bond with us all of a sudden?" Mira asked.

Stan had replied, "Come on guys, this is gonna be great! Since my daughter Sky has her sons, I don't have fishing buddies like I used to."

"It's true." Skyla said to the kids, "Not even the guys at the lodge won't go with him. They don't like or trust him."

"Well I'm all for it!" Gary said with excitement.

"Might as well." Andrew said before turning to his little brother, "Bet I can catch a bigger fish than you!"

"You're on!" Gary said. The two boys both ran to the rowboats nearby. "Well, I'm gonna go grab a boat. I'll see you later, and dad, you take care of them alright?" "Hey, I raised you on my own didn't I?" Stan said laughing at his own joke and Skyla laughed with him. With that she went to catch up with her sons.

Dipper felt a bit skeptical about this. Mira and Mabel looked at one another, "Dipper, I think he actually wants to fish with us." Mabel said.

"He might really want to bond with us." Mira said.

"Hey I know what will cheer you sad sacks up." Stan said, before putting fishing hats on their heads, "POW! Pine fishing hats! That's hand stitch you know?"

The triplets took off their hats and looked at the hand stitch that Stan had done for them. They looked over Mabel's shoulder and saw the "L" in her name fall over; They looked back up at their Grunkle Stan, "It's just gonna be you, me, and those goofy hats for the next ten hours!"

The triplets mouths dropped at that, "TEN HOURS?" They said.

"That's like… Forever." Mira said.

"I bought the joke book." Stan said, holding up a book that was titled 1001 Yuk Em Ups.

"No! NO!" Dipper said looking horrified.

"Not the joke book! Anything but the joke book!" Mira exclaimed.

"There's gotta be some way out of this." Mabel said to her siblings.

Just than they heard someone screaming and shouting throughout the lake. This certain someone was a person by the name of Old Man McGucket.

"I'VE SEEN IT!" He shouted, "I'VE SEEN IT AGAIN!"

He ran throughout the port and flipped tables and other things that came in his way; he at one point smacked a sandwich out of a man's hand. "THE GRAVITY FALLS GOBBLEWONKER!" McGucket continued to yell, "COME QUICK BEFORE IT SCRABDOODLES AWAY!"

Randomly, McGucket had just started dances all the while he was laughing uncontrollably, which struck the triplets as odd.

"Umm… Is he dancing?" Mira asked.

Mabel made a kitten face, "Aw, he's doing a happy jig."

"NOO!" Mcgucket shouted, "It's the jig of grave danger!"

The owner of the rowboats and fishing supplies by the name of Tate, came out with a spray bottle, and had started to spray at Old Man McGucket. "Hey, hey!" He said, "Now what did I tell you about scaring my customers? This is your last warning dad!"

"Dad?" The triplets said with shock.

"But I got proof this time!" McGucket said using his hand to block the water, "By gummity!"

Everyone, including the triplets and Stan went to the dock where McGucket said he had proof. When they got to the docks they saw that the ship was broken in half beyond repair. "BEHOLD!" He shouted before explaining to the people, "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 here!"

McGucket was referring to Stan, who was oblivious to the conversation they were having just now.

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

Everyone that was listening didn't really seem to buy it, though the triplets had listened carefully since this kind of thing peaked their interest. A policeman by the name of Sheriff Bulbs had spoken among the crowd, "Attention all units! We got ourselves a crazy old man!"

Everyone but the Pines had started to laugh; Tate however just shook his head in shame. "Aww donkey spittle! Aw banjo polish!" McGucket said as he walked off the dock. Thus everyone had left the dock except the Pines.

"Well, that happened." Stan said before jumping into a rowboat that was labeled Stan O'War, "Now let's untie this boat and get out on that lake!"

Dipper turned to his siblings, "Did you guys hear what that old man said?"

"Aww donkey spittle!" Mabel said doing an impression of McGucket.

"Aw banjo polish!" Mira said with an impression of McGucket as well.

"The other thing." Dipper said, "About the monster. If we can get a photo of it, we can split the money between us!"

"That would be a whole lot of money." Mabel said.

"We can get a TV in our in room back at home!" Mira said.

"Yeah but think bigger!" Dipper said, "Just imagine what you could do with all of that prize money!" Mira still fantasized about the TV along with virtual reality, while Mabel was fantasizing about something else entirely.

Mabel stood tall in the human sized hamster ball that was in the shade of pink. She towered over a hamster that was in the same color as her's was. "Not so high and mighty anymore!" She said to the little hamster. The little hamster bowed his head and Mabel couldn't help but laugh. She rolled out of the shack, breaking the wall in the process. She soon found herself in the streets where she came across two men named Xyler and Craz.

"Hey boys!" She said getting their attention, "You can look, but you can't touch."

She rolled away while saying squeak, squeak.

Xyler and Craz jaws dropped at the sight of Mabel in a hamster ball. They turned to each other and had said only one thing, "Awesome!"

"Mabel? Earth to Mabel?" Dipper said snapping his fingers in front of Mabel's face which snapped her back into reality.

"You were daydreaming again." Mira pointed out.

"Dipper! I am on million percent behind you on this!" Mabel said.

"Count me in too!" Mira said.

Dipper went over Stan who was busy untying the rowboat. "Grunkle Stan, change of plans: we're taking that boat, and we're gonna go find that Gobblewonker!"

Dipper, Mira and Mabel began to chant, "Monster hunt!" but stopped when McGucket tried to join in on it. They just looked at him, and McGucket walked away awkwardly. They soon a large honking sound. They turned and saw Soos, driving a boat much larger than Stan's boat. He pulled up the boat just at the port.

"You dudes say something about a monster hunt?" Soos asked them.

"Soos!" Mabel and Mira exclaimed.

"Wassup hambones!" Soos said, brofisting both Mabel and Mira, he said to them, "Dude you could totally use my boat for your hunt. It's got a steering wheel, chairs; normal boat stuff."

Stan had then said to them, "Okay, alright, 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 Grunkle Stan!" The triplets looked to Soos, who was doing a robot dance, than they looked to Stan; they saw the boat leaking, and sniffing his left armpit when he smelled an awful stench. The triplets turned to Scuttlebutt island, before making their decision.

"So what do you say kids?" Stan asked feeling confident. Though he was shocked when he heard the triplets laughing; he looked up and saw them driving away on Soos boat.

"We made the right choice!" Mabel shouted as the boat drove away.

"Ingrates!" Stan shouted with his fist in the air, "Ah who needs em? I got a whole box of creepy fishing lures to keep me company." Stan looked into the box but after a moment of looking into the box he saw flies buzzing around over the baits. He groaned in disgust before closing the box.

The triplets and Soos were on their way to the island known as Scuttlebutt. The raised the flag which was a beach towel and hoisted the anchor which was a cinderblock.

"WE'RE GONNA FIND THAT GOBBLEWONKER!" Mabel shouted with confidence.

"WE'RE GONNA WIN THAT PHOTO CONTEST!" Dipper shouted with confidence as well.

"You dudes got any sunscreen?" Soos asked.

"We're gonna…" Mira started to say before shouting, "... GO GET SUNSCREEN!"

"YAY!" They all cheered before making a u-turn. As they drove they didn't notice that a strange creature was swimming just underneath their boat.
