It was a typical day in Gravity Falls.

Dipper was alone in the woods, on an expedition searching for answers.
Searching for answers explaining the many mysteries of Gravity Falls.

"I wonder if I'll answer any of the many mysteries of Gravity Falls." Dipper said to himself.

He carried his precious Journal 3. He had it opened in front of him as he walked, reading it, not really watching where he was looking.

He danwed his tradtional attaire. Including his signature blue cap with the pine tree symbol.

"This hat may be tacky, but it's just... me." Dipper said to himself.

"Now then, what would happen if..." Dipper said.
He took one more step, and he fell into a pit he couldn't see under the brush.
"AAHHHH!" he screamed as he fell down the pit.

He landed on his bottom, in some dingy old hole.

"What sort of trouble have I gotten myself into now?" he asked himself. He was in a 'I like talking to myself out loud' kind of mood.

In front of him, was an angry puma. It was hungry, and lunged forward.

"AAAAHH" Dipper crawled backwards, dropping his cap in the process.
The puma pounced and tore into his cap.
"HEY! MY CAP!" he yelled.
The puma ripped and teared his hat, and spit it in front of him.
Dipper grabbed it, and ran from the puma, and hid in a smaller sub cave.

"Aw man. It's not like the Mystery Shack has a surplus of these things!" he said.
"Okay they do, but this hat is mine. I picked it the day Mabel and I came to Gravity Falls."

Dipper shed a single tear.

"And now it's ruined." he threw his hat behind him, hitting some wall, knocking some gravel loose.

And then, light peered through the newly wall. Something was glowing on the other side.

Dipper was fascinated.

"Hmm. Could this answer all the questions I've had thus far?" he asked himself.

He proceded with caution towards the light. They say don't go into the light, but Dipper was too curious for his own good.
He got next to the wall with light coming out.
He put his head next to it, and started moving some more gravel away, exposing more light.

As he was slowly clearing the gravel, out of nowhere, and quite suddenly.
So suddenly, it startled Dipper.
A creature popped out from the wall!

"AAHHH!" Dipper was startled. He was very easily startled. His heart skipped a beat, and he was breathing fast.
When he caught his breath, he was able to see what popped out of the wall.

It was a little ghost mostly covered by a giant white top hat. There were giant googly eyes on the front of the top hat.

"Not another ghost!" Dipper yelled.

The thing stared Dipper in the soul for a few moments, and then spoke.

"Hey wat'chu got there kid? Some old little book?" asked Cappy.
"Uh... this is my journal. I write it in, and uh... stuff." Dipper said.

"That's neat, but tell me kid." it said.
"Yeah?" he asked.
"What happened to your little cap here?" the ghost asked.
"Oh that, it got a bit torn up when I fell down here." Dipper said.
"So, does this hat mean a lot to you kid?" the ghost asked.
"Yeah, my Great Uncle sells hats like this at his tourist attraction. He let me have this for free the day my sister and I came here to Oregon for the summer. It meant a lot, but oh well." Dipper explained.

The ghost was sobbing.

"That's the second saddest story I've heard about a hat." the ghost said.
"What's the first?" Dipper asked.
"Not important. Where did you say we were? Oregon? This ain't Brooklyn!" it said.
"Do you need to be in Brooklyn?" Dipper asked.
"Not... really... I mean. I guess I could hang around here. You seem to need some help." the ghost said.
"I can't just leave you here with a torn hat! Hats are like companions that sit on your head... or something." it said.

"Um... who are you?" Dipper asked.

"Oh, my apologies, I haven't introduced myself yet. My name's Cappy." it said.

"...Cappy?" Dipper asked.

"Yeah, now stand back, and let me work my magic!" said Cappy with.

With that, Cappy spun around holding Dipper's hat, and then poof! Cappy became Dipper's hat, restoring it to mint condtion.

After the poof, the hat landed on Dipper's head.

"Wow thanks Cappy... Cappy?" Dipper thanked Cappy, but he was nowhere to be seen.

"You're welcome!" Cappy's eyes popped out of the front of Dipper's hat.

"Oh, there you are. So is this like, your power? Possessing hats?" Dipper asked.

"Yeah, you got a problem with that?" asked Cappy.

"No, it just seems... random?" Dipper wasn't sure.
"Hey, I don't tell you have to live your life kid. Now what's your name anyway?" Cappy asked.

"I'm Dipper Pines." he said.
"Dipper? What kind of name is that? Do your parents hate your or something?" Cappy said.
"Hey! For your information, it's only a nickname, my real name is... well, I don't want to talk about my real name." Dipper said.
"Fair enough, I have secrets I'm keeping, and you have yours, so I guess we're even." Cappy said.

"So uh... now what?" Dipper asked.
"I don't know, you tell me! I'm on your head after all." Cappy said.
"Yeah, I guess so. Let's go home." Dipper said.

With that, Dipper made his way out of the hole, and was walking through the woods back to the Mystery Shack.

"So, tell me about yourself Cappy. What are you? Where do you come from?" Dipper asked.

"I'm a hat spirit thingy that possess hats. That's all you need to know about me." Cappy said.

"But where do you come from?" Dipper asked.

Not much happened on the walk. Dipper prodded for information, but Cappy was very hush hush about any information about itself.

Dipper made his way into the Mystery Shack, and went upstairs into his bedroom to take it all in.
As he entered his room, he noticed Mabel was in there.

"Woah bro! What's up with your hat?" Mabel asked.
"Uh... nothing." Dipper said. Cappy's eyes retracted.

Dipper sat on his bed, and took off his hat to look at it.
"So like... you're my hat now?" Dipper asked.

"What are you doing talking to your hat bro?" Mabel asked.

Dipper was peeved, so he threw his hat at Mabel, and when it hit her, magic happened.

The hat flew onto Mabel's head, and Dipper... well. His body got sucked into the hat.

"AAAAH!" Dipper screamed internally, but no one could hear him per say.

"AAAHH!" Dipper screamed from the outside, but from within Mabel's body!

Dipper had possessed Mabel.
Dipper in Mabel's body got up and looked at the mirror.
"Oh man, not again." he said.
He looked up and saw Mabel was wearing his hat.
"No offence Mabel but you do not sport this look very well." he saying that his hat didn't look good on Mabel. You be the judge though.
"I wonder if-" Dipper removed the hat from Mabel's head, and more magic happened.
Dipper flew out of Mabel's body, returning everything to normal.

"WOAH! WHAT JUST HAPPENED?" both twins said simultaneously.

"Cappy! You got a lot of explaining to do!" Dipper said.

"So I guess it's time I told you. Basically, you can throw me onto someone else, and you can control their bodies!" Cappy said.

"That's uh..." Dipper trailed off.
"Sort of unnerving." Mabel said.

"I mean, do we need yet another way for body snatching to occur here? There's that weird carpet that made us Switch bodies. Bill took my body once. There was that ghost who possessed Mabel and... *shivers* and now there's you and your freakish abilities." Dipper said.

"...I see... 'freakish', I guess that about sums it up." Cappy said in a slump.
"No no, come on. I didn't mean it like that. I'm a freak too, check out my birthmark." Dipper showed Cappy his birthmark.
"Heh, I guess we're all freaks. Except for you miss, you're pretty cute." Cappy said.
"Heh, you're such a charmer Cappy." Mabel said.

"Hey, I got an idea. Let's go try this on Grunkle Stan!" Mabel said.
"Heck yeah!" Dipper said.

They ran downstairs to go try the hat trick on Stan.

Dipper and Mabel peered from behind the corner, giggling at the thought of the hilarious prank they were going to do.
Dipper got ready, and flung the hat towards Stan. It hit him square in the face, but nothing happened.
"Hey! Who threw this?!" Stan asked.

He stood up, and saw it was Dipper and Mabel.

"Kids! Do we need to have a long in depth conversation as to why it's rude to throw hats at people?" Stan asked.
"No sir, we're good. Heh. Now uh... we'll be on our way." Dipper said.

Dipper took back his hat, and he and Mabel went back upstairs.

"What happened back there Cappy? Why didn't you work?" Dipper asked.
"I forgot to mention, I can't possess anyone or anything that's already wearing a hat. It makes sense when you think about it really." Cappy said.

"Hmm, I guess that eliminates Stan, Soos and Wendy. It would have been nice if you said so earlier... wait... possess anything?" Dipper was curious.

"Yeah, you can possess objects too!" Cappy said.

"Hmm, possess objects huh?" now Dipper's imagination went wild with the possibilities.

"I know that look bro. That's your thinking look." Mabel said.

"Yes it is Mabel. Yes it is." Dipper said.

What kind of ideas was Dipper thinking of? What else could Cappy do? When the heck does the conflict come into play? Find out in the next chapter.
