Dipper Pines searched through his mystery journal for another mystery to unravel. "Hm? What's this?" the pines boy said as he leaned in closer to his book. "A Vortex Generator?" The twin sister to dipper, Mabel, burst in the room holding a bedazzled pig. "Dipper, Look!" Mabel ran to her brother and rubbed the big onto him. "Isn't he beautiful?" the girl said as she huggled the pig. The colorful, bedazzled pig oinked as it was pushed into Mabel's sweeter. "You always find a new way to surprise me, Mabel." Dipper looked at his sister dumbfounded.
"Uhh..Hey, Mabel? Want to go look for this with me?" he should his twin the page from his journal. "Well duh! Let's go!" she grabbed his wrist and ran down the stairs. Dipper fell halfway down the stairs and into Wendy. "Gah!" shouted the red head. "Hey, man. Totally not cool." Wendy laid on her stomach with dipper laying diagonal over her back. "Huh?" Dipper tried to sit up and his hand cupped Wendy's left butt cheek. "Whoa, dude. Buy me dinner first." The red head chuckled. Dipper looked where his hand was and quickly panicked, causing him to fall backwards, off her.
Mabel laughed. "Look Soos. Dipper is getting fresh with Wendy." Soos looked down at the two on the floor. "Whoa, dude! You finally did it! Way to go, Little Bro." Soos said with a slight chuckle. Grunkle Stan walks into the room where all the commotion was coming from. Hey! Hey! I don't pay you enough to sit around." Snapped the old man. Wendy finally stood up and dusted herself off. "You don't pay us at all." She said with a crooked smile. The old man pointed at her. "Exactly and I don't sit around here making money so I could pay you." He ended his discussion with his co-workers and left.
Dipper stood up with a blush. "S-sorry, Wendy. It was all Mabel with the pulling me down the stairs and-"Wendy cut him off with a pat on the head. "It's okay, man. Don't flip your lid." The red headed teen laughed. Dipper picked up his journal that had fallen near the stairs after his accident. "Well, Mabel and I are off to…um...Do twin stuff." He said as he ran out the door and into the woods. "That was awkward~" Said Mabel in the giddy voice. "Yeah. Leaving now saved me from any further embarrassment." The male twin opened his book as he walked. "It says its not far from here. Just a little ways past the graveyard." He pulled out his black light and shined it towards the book. "What?!" he looked startled at the page. A three armed, devil horned monster was drawn onto the page in invisible ink. In bold letters it read. DANGER! Mabel was happy skipping around when she tripped and rolled down into a hole. "Ack!" the young female lay at the bottom of the trench with dirt and grass in her braces. "Mabel!" Dipper yelled as he carefully skid down the side to her. "You alright?" Mabel stood up and swallowed the dirt and grass. "Fruity." She said happily. Dipper looked at his twin in disgust. "There is no way we are related.
Just then a loud roar was heard by the Pines Twins. "Wahh!" the both jumped scared. "W-What was t-that, Dipper?" Mabel looked toward where the sound had come from. "Possibly the monster the book warned me about." He said to himself but out loud. "What?!" Mabel glared at him. "You knew this would be dangerous but you still went along for some stupid machine that may or may not be there?!" she yelled at him in an irritated tone. Dipper looked down and felt horrible for putting her in danger possibly. "Yes…" the Twin quickly perked up with a smile. "Okay~" she giggled and marched on. Dipper watched for a few seconds in amazement of her swap of attitude. The two walked closer to the loud roar. A few moments later they found a giant sleeping, three-armed, devil horned beast, and was lying on the ground. The snore that came from the monster was extremely loud and echoed throughout the forest. "Wow!" Mabel said loudly causing the beast to slightly move. "Mabel." Dipper quietly yelled. "We have to walk past him quietly and carefully. As the two walked past the beast Dipper stepped on a twig. The noise surprisingly echoed through the forest. The beast red eyes quickly shot open and looked at Dipper and Mabel who were sneaking past its face.
The beast roared loudly at the two. The twins begun to run towards a cliff. "Dipper, What do we do?" just as soon as Mabel finished her sentence they fell into a hole and onto a cold ground. "Ugh…." The two quickly tried to get up as they saw the monster jump down the hole. "Run, Mabel!" Dipper pulled his sister along with him as he ran. The beast gradually began to catch up with the two. "This way!" Mabel yelled as she quickly turned down a hall. At the end of the hall was a portal like machine. "That's it, Mabel. We found it!" said Dipper as he ran towards it. "Were going to have to go through it and hope for the best." He said with a determined look on his face. "What?!" Mabel looked at him shocked. "Too late." He pushed her into it and jumped in as well.
Dipper opened his eyes when hearing Mabel screaming. The screech caused him to quickly jump and see what was wrong. "Mabel?! What's wrong?!" he tuned and say his sister taller and more in a more mature body. "Dipper! I…I think we're older?" Dipper looked at her with disbelief. "That's Impossible." Dipper stated. Mabel looked towards her brother who was taller than her now. "Whoa. You're like a giraffe, Dipper" she chuckled. "What?!" he looked down at his legs that were taller. "Dipper, we have to be older. Explain these." Mabel squeezed her breasts that were now a C-cup. "Wahh! Mabel, stop!" Dipper closed his eyes trying to get the picture out of his mind. "Hey. Look. We're at the graveyard. Let's go show Soos. Maybe he knows what happened." Mabel said as she started running towards the mystery shack.
The twins ran through the door yelling. "Soos!" Dipper crashes into Wendy, landing on top of her. They looked at each other for a moment before noticing what had just happened. "D-Dipper?" asked the red head as he helped her up. "Heh~ Y-yeah…" He rubbed the back of his head and looked away, blushing. "What happened to you, man?" Wendy looked at the twins confused. Soos and Grunkle Stan entered the gift shop and looked at the three. "No friends, Wendy. Buy something or get out!" he irritatedly said with a glare at the twins. "Grunkle Stan, it's Me and Dipper!" said the older female Pines twin.
The Two twins were taller and had so many different features. Mabel was 5'6" (same height as Wendy). Her cup size had gone up to a "C" and her hair was longer. Dipper was 5'9" and towered over his twin. He had a bit of peach fuzz growing on his chin. Grunkle Stan looked at the two with his jaw dropped. "How did this happen?" he asked. Mabel quickly answered. "Me and Dipper were out looking for this vortex machine thingy, but a monster jumped out and chased us and cornered us in with the machine so we had no choice but to jump through it!" the twin yelled in excitement. "What a growth spurt, Dude." Soos said as he looked at dipper, who was the same height as him. The two males shared a small laugh, then Soos leaned over and whisper in Dipper's ear. "You have a way better chance with Wendy now, Dude." Dipper focused his eyes on the red head who was staring at him. He quickly blushed and tried to step back put hit his head on the doorway. "Shit!" he rubbed his head. Every stared at him with their mouths dropped when they heard the vulgar word come from his mouth. Dipper looked at them as he took off his hat to rub his head. "W-What?" he was confused. "You cursed!" said Mabel as she glared at her twin brother.
"So…" said Dipper as he put the hat back onto his head. Grunkle Stan clapped his hands and held a proud smile. "My boy has finally made it to man hood." He walked to dipper and put him in ahead lock as he gave Dipper a nuggey. "Hey!" Dipper groaned as he tried to pull away from his Grunkle Stan's grasp. Dipper pulled away to hard and backed into Wendy, causing her to giggle. "Watch it, Man." said the redhead. "Uh...My bad, Wendy." He chuckled slightly and rubbed his arm. "You sure did grow a lot this summer." She joked around with him. "Yeah, I guess. But, Hey! I'm still the same guy." He laughed and shrugged. "The same little guy who was a crush on me?" she asked playfully with a small laugh. Dipper nervously laughed as he looked away slightly. "Come on, dude. I'm still me." said Wendy as she nudged him. Dipper shared a small smile with his redheaded friend.
Soon everyone was over the fact that the twins had somehow become older. Mabel went to show her friends her knew older body. Grunkle Stan was in his room counting his profits and cutting things they truly need, like the water bill. Soos went into town to get lunch for him and Wendy. Dipper was left over in the gift shop alone. He looked around and sighed as he grabbed a broom and started sweeping the shack. Wendy walks in from her break as she waited for Soos to return. "Hey, Big Dipper." joked the female with Dipper. "Huh?" looked up at his crush and panicked, making him back into the wall nervously. "Calm down, man. It's just me." She smiled warmly at him and shrugged. "I-I see…" he stuttered. His 18 year old mind was flipping through possible actions and fantasies about them both. "Y-yeah. S-sorry I'm still getting use to the new me…I guess." He scratched the back of his neck and looked away. "You gotta look on the bright side, man. You get to do much now that you're the big one eight." She punched his arm lightly and giggled.
He looked at Wendy with a small smile. **Maybe Soos is right…maybe…just maybe I actually have a chance.** Dipper had been looking at Wendy lovingly which made a blush slowly form on her face. Dipper noticed he was doing it and blushed deeply. "I-I'm so S-sorry…Idiot." He whispered the last part under his breath and looked down at his feet. Dipper quickly looked up as he thought about how he just made his crush blush. "Wait?! Did you just blush?" he asked her confused. "Huh?! N-no!" she denied quickly and looked off to the right. Just then, Soos barged in with food. "Hey, Bro? Didn't know what to get you so I got one of everything." He sat it down on the desk and Wendy walked to the desk, Dipper followed behind. "Damn, Soos." Wendy said with a chuckle. Dipper stared at her after he heard her beautiful lips say a dirty word.
