I do not own Gravity Falls or any character of this great show. Enjoy!~

Chapter 1: Well, this is a problem.

Stanford Pines knew that he had to be careful when he was working on a project, if meeting Bill Cipher wasn't a good example about how dangerous an investigation or project could be, he didn't know what was.

But maybe when he tried to initiate his new machine, he should have been behind it, not in front of it where the laser could shot him. Now he knew two important things:

1-Mabel was right when she said that he should sleep more or his brain wouldn't work properly and he could do a silly thing.

2- Now he was a 12 or 13 year old boy.

"Calm down" Stanford thought, trying too hard to not lose his composure at that moment. "I just need to turn on the machine again and put it on reverse, so I can be a grown up again…" But when he was about to do that, he gasped.

He hadn't programed the machine so it could make living beings grow older, he wanted to try to make an old goat younger and, if it worked, then he would make possible for it to go back to normal.

The first step took him weeks, and that meant…

"Oh no."

"Grunkle Ford?" Dipper entered the lab, looking for his great uncle. "Dinner is ready, Grunkle Stan made spaghetti, Mabel having a sleepover in Grenda's house, where are…?"

Dipper stopped talking when he spotted a young boy in his grunkle's big coat, who was shrinking a red sweater with a flashlight.

"Who are you?" Dipper asked, surprising the boy, who yelled and turned around.

"Dipper." The boy seemed nervous." I… I need your help."

"Where is my great uncle?" Dipper asked, not trusting the kid at all. "Who are you?"

"It's me Dipper! It's Stanford!" the boy exclaimed, when Ford saw that Dipper didn't believe him one bit, he extended his arm so his great nephew could see his hand. "Look, I have six fingers. It's me Dipper."

Now Dipper was shocked. "Grunkle Ford?" The boy looked at his uncle with wide eyes. "How on earth did this happen?"

"I was working on a machine that could change the biological age of living beings. However, I only programed the machine to make individuals younger, not older and… this happened."

Dipper sighed, rubbing his eyes, not believing what he was seeing. "Well, what are you going to do now?"

"I can program the machine to get back to normal, but that will take me days. Now I'm trying to shrink my clothes so I can fit in them but…" Ford sighed when he saw how his sweater had now one large arm and the rest of his clothes were as tiny as a mice. "I believe this flashlight was damaged in Weirdmageddon."

"I can borrow you some of my clothes." Dipper offered, rubbing the side of his neck awkwardly. "They are not the best, but they can help for now."

"Let me get this straight". Stan did not believe what he was seeing, he pinched himself in the arm to make sure he wasn't dreaming. "In one of your nerd projects, you ended up being a weird 13 year old boy again?"

"Pretty much." Ford answered, now wearing a black t-shirt and jeans from Dipper. "I will need a few days to go back to normal. I already have the blueprints, now I only have to make sure that the changes I need to do in the machine will be successful."

Stan sighed and looked at his twin for a moment before going out of the room. "Well, it's been a long day, let's sleep for now. Tomorrow we will have to tell Mabel about all this."

Ford looked at the direction his twin had gone, with confusion written in his face. "That's weird. Stanley never misses dinner."

"Well, I guess seeing your twin as a young boy can make you want to skip dinner." Dipper said, a little worried about his grunkle.

"I mean, seeing his twin like this, after all they have been through… this must be really hard for grunkle Stan." Dipper thought with sadness.
