Grunkle Stan stumbled into the Mystery Shack living room holding a pint of ice cream and a box of tissues. He sat lazily into the chair and was about to turn on the TV when his niece and nephew walked through the doorway.
“Uh, hey kids, how’s it going” Grunkle Stan said, “Uh you guys want to head somewhere else?”
“We’re bored Grunkle Stan” Mabel said as she and Dipper slouch onto the floor, lying on their stomachs, “there’s nothing around here that we want to do.”
“Yay that sounds interesting, so about you guys leaving.”
“Grunkle Stan,” Dipper started, “do you have anything we can do, some chores even; see were that bored that we been reduced to begging to do chores.”
Grunkle Stan coughed and said “Uh, why don’t you kids go to the attic and not bother me for about three hours.”
The twins lazily jumped off their stomachs and walked to the stairs up to their room.
“Alright, time for the ‘Duchess Approves’” Grunkle Stan said excitedly turning on the television.
The twins laid on their own beds. Waddles waddled into their bedroom going up to Mabel’s bed.
“Ah Waddles, your cuteness takes off some of the day’s boredom” Mabel said while she happily squished up his face. He started to lick her face. She started giggling and got excited that her feet started to kick the wall. Her kicking caused the shelf above her bed to shake. Then the tattered book with the six-fingered hand fell of the shelf landing next to Mabel.
She lifted the book, “Hey Dipper find something interesting in your journal for us to do.” She threw the book at Dipper which landed open on his face.
Dipper pulled the book off his face and looked at the page it was open to. “Hey Mabel, come look at this.” Mabel quickly leaped off her bed to see what her brother had seen.
“What’s up Dip, something about a universe of only pigs?”
“Nothing about that, but it is something about an alternate universe,” the boy said, “but here’s was it does say:”
Dipper read aloud:
“During my investigation of the Gravity Falls woods, I have come across portal in a cave to where I am unclear, but my theory is that it may be an alternate universe which would explain how many of the creatures got to Gravity Falls. Though I will not enter due to what may lie on the other side I will regular study it to see what may come out or go into the portal.”
Mabel’s eyes suddenly got wide, “Dipper do you know what this means!”
“We ignore the book and just continue to not bother Grunkle Stan,” Dipper answered.
“No silly,” Mabel said as she playfully pushed Dipper, “we find the cave and go into the other universe.”
“Mabel that’s a terrible idea,” Dipper quickly pointed out, “who knows what could be on the other side of the portal, what if their not alternate universes. What if it’s like a black hole the will just kill us when we enter it.”
“Come on Dipper where’s your spirit of adventure, don’t you want to find alien pig universe.”
“Where’s your sense of certain death, Mabel,” Dipper nervously said.
“What would rather do bro, go find the portal to an another world or stay here and not bother Stan for two hours?”
“THREE HOURS!” Grunkle Stan shouted from the living room as Mabel gave her brother an irritated glare.
“I guess so,” he said, “but… we don’t know how to find it.”
Mabel grabbed the book out of Dipper’s hands and quickly skimmed it over. She then pulled out a folded piece of paper. “Look Dipper, a map to find the portal.”
Mabel unfolded the paper showing a map of Gravity Falls and a trail with a big “X” along side the mountain. Mabel pointed to the map, “See Dipper, here is the Mystery Shack and the trail is just along the forest path.”
“Mabel, I just don’t think it a good idea,” Dipper now pleaded with his sister.
“We’ll I’m going and you can come with me or stay here.”
Mabel left the room and ran down the stairs but was stopped by Dipper, “Wait Mabel I’ll come with you…just to see the portal.” Mabel grabbed his hand and pulled him outside.
The twins stood just outside the Mystery Shack, Mabel examining the map, trying to find which way they should enter the woods. It was quiet until the twins heard a rustling of leaves. “That way we go,” Mabel said pointing in the direction of the rustling.
“Uh Mabel are you sure that is the right way, maybe I should take a look at it,” Dipper said as he began to reach for the map.
Mabel slapped his hand away, “I know this is the right way, I can feel it.” She began to walk off in that direction with Dipper slowly trailing behind her.
After about what seemed like an eternity of walking for Dipper he excused himself to quickly tie his show.
“Hurry up, I must know what is in that portal!” Mabel said clutching the folder paper close to her chest.
“I’m doing it,” Dipper sternly responded, but really he was taking his time as to stall their process to the portal.
After five minutes Dipper finished his shoe tying. “Are you done now, Dipper?” Mabel firmly asked.
“Yay I’m done,” Dipper replied with an upset tone. He uneagerly followed knowing his plan to stall their trip weren't working. “Uh, wait Mabel…I think I left my book back at the shack. We should go back to get it…you know, just in case.”
“No you didn’t.” Mabel pulled out the book, “I grabbed it so you wouldn’t want to go back. No quit stalling, we’re going to find the portal and your going to like it.” Mabel grabbed Dipper shirt collar and started to drag him.
Mabel walked more into the forest with the map in one hand and Dipper’s collar in the other. She had to drag Dipper across many tree roots and plants that Dipper eventually just started to walk because his shoe’s soles were wearing down. Soon the twins found an open area between the trees and the mountain. Soon Mabel got really excited.
“I think I found the location of the portal,” Mabel excitedly told her brother.
“Where is it then,” Dipper said, “Looks like I was right. This whole ‘adventure’ was completely pointless. Now Mabel, I want you to say I was right.”
Mabel had already left Dipper standing, talking to himself. When he realize where she was he ran up to see her in awe at the mouth of the cave which housed the portal. The twins now just stood there for a few second until Mabel broke the silence.
“Well, lets go jump in it,” Mabel saying quickly enter the cave. Dipper grabbed her shoulder, “Mabel we don’t just go jumping into random portals in the middle of the woods until we make sure it safe.”
The twins stepped up to be a few inches from the portal.
“I don’t think it’s a safe idea, Mabel. I’m not going in it.” Dipper firmly stepped back.
“That’s okay Dipper, your too chicken to go in anyway,” Mabel mockingly replied.
“What! I’m not chicken,” Dipper said directly to his twin.
“Bak, bak, bak,” Mabel sounded out. She put her arms on her hips and pretended to eat food off the floor, “I’m a chicken and my names Dipper.”
Dipper got angry, “I’ll show you whose chicken.” Dipper ran at full speed into the portal. Mabel quickly stepped into the portal after him.
The twins popped out of the portal in another damp cave. Mabel got up on the floor and looked around. She went to the mouth of the cave and saw a forest.
“Dipper look, it’s a different forest.” Dipper got up and came to see what his sister was talking about.
“Whoa, where are we?” Dipper asked.
“A better question would be to say when are we?” Mabel rebutted.
“We didn’t time travel Mabel, we teleported…or something.” Dipper told his sister.
“Well no point in just standing around Dipper, I going to go in the forest and you can stay here with your chicken self.”
“I not scared Mabel, I’m coming with you,” Dipper sternly said to his twin.
The twins walked into the forest interested for what may lie within. As Mabel excitedly admired anything and everything in the forest, Dipper kept a close eye on them to be aware of anything that may pop out at them.
Mabel and Dipper continued their walk when suddenly Mabel spotted something that appear to show intelligent life.
“Hey Dipper,” Mabel pointed out, “I think there is like a building or something over their in the distance. Lets go see it.”
Dipper quickly grabbed his sister sweater, “Mabel you made me jump into a portal to who-know-where. We are not going to see anymore mysterious buildings especially in a forest in someplace we don’t know.”
“Alright Dipper no need to flipped out.” She giggled at his bit of anger “Lets just go to the clearing over there instead,” as she pointed to the opposite area of where the building was.
The two kids continue their walk to the opening. The kids were about a few meters to the clearing when suddenly there was a branched that snapped.
“Whoa! Mabel did you hear that?” Dipper said suddenly looking behind him.
“Dipper, it’s probably just the wind.” Mabel happily replied.
“You know that when someone say something is just the wind, it’s not the wind,” Dipper said.
Mabel shrugged, “Wind is a weird thing Dipper, you just don’t understand.”
Dipper rolled his eyes at Mabel’s response. Dipper ran up to catch Mabel, but soon he realize that he and Mabel had just reached the opening. They looked around and they saw a cottage not to far from them.
“Hey look over there,” Mabel said, “It’s a cute little cottage lets see if anyone is there.
“Mabel what did we just talk about when visiting mysterious buildings?” Dipper said to Mabel.
“You said not to visit weird buildings in a forest.” Mabel rebutted.
“Fine Mabel, well visit the cottage,” Dipper said with a shrug.
The twins walked out of the outskirt forest and into the field suddenly their walk became much slower and the twin started to nod off.
“Hey Mabel,” Dipper paused to yawn, “Do you feel really tired all of a sudden.”
Mabel had already fell on her back fast asleep. Dipper fell on to his knees and eventually on his stomach trying to keep his eyes open. When he tried he was able to keep his eyes open too see a yellow figure in the distance until his eyes were completely shut.
