Hello one and all to my Phineas and Ferb and Gravity Falls crossover

The Halfheart and the Pinetree!

Now for some disclaimers that I naively thought to put in my last story:

Phineas and Ferb/Gravity Falls do not belong to me.

PnF belong to Dan Povenmire and Gravity Falls belong to Alex Hirsch.

And with that out of the way, it's time to start this new story!

On a bus heading to Danville…

We focus on a worn down, dirty bus. Inside are it's only two passengers. Twins Dipper and Mabel Pines, two 14 year old teens. They both had peach skin and were staring ahead with different expressions. Mabel, the self proclaimed 'alpha twin' wore her usual shooting star sweater and purple skirt and red headband and wore a big smile revealing braces underneath. Dipper, with a stern expression, wore his usual pine tree cap and red shirt with a long-sleeved black jacket and jeans.

Dipper's POV

Hi, my name's Dipper Pines and the girl sitting next to me is my sister, Mabel. Normally, at this time of year, we would be getting ready for school in Piedmont,California. But our parents decided to go on a year-long vacation in Hawaii after winning a sweepstake. Big coincidence right? Our only source of protection deciding to leave us for an entire year? But I know better. I know he is all behind this. He left us alone for the rest of our middle school life. But now that we're in high school, he's come back just to ruin our lives just like he did last summer…

Normal POV

Screech!

Suddenly, the two were launched from their seats to the front of the bus.

"Final call for Danville." the bus driver irritably said. Before they got off, Mabel slapped a 'thank you' sticker on his cheek, making him growl even more. They then watched as the bus peeled out, knocking over a few trash cans along the way.

"Well, here we are sis." Dipper said miserably as he pointed to the small, yellow house in front of them. However, it was just the right size for the two of them. And it just so happened to be cheap enough for their parents to pay it off for a year. Again, coincidence right?

"Can you believe it Dip? It's like we're grown ups!" Mabel cheered. Dipper smiled at her cheers. Somehow, she was always able to put a smile on his face at even the worst of times.

"Yeah it is. But remember that we do have a limited amount of money and that we should spend it wisely." Dipper informed her. She blew a raspberry at him.

"I know, I know. I won't spend it all on food. After all, I have this!" She exclaimed as she pulled out a plastic bag, full of packs with yellow dogs and pink frosting on it.

"Mabel! Why would you bring those? Don't you remember what happened last time you ate those?" Dipper asked in shock.

"Don't worry! I'll make sure only to three packs a day instead of five." Mabel assured. Dipper facepalmed at this. Of course, there were times where she would give him more than just a headache. He then grabbed the key from his pocket and opened the door to their new home.

In their neighbor's backyard…

"Hey Ferb, did you see that? It looks like we got some new neighbors!" a red haired 14 year old boy announced. He wore an orange jacket with blue jeans. This was Phineas Flynn. The other boy he was talking to wore a lavender shirt with a purple vest over and dark blue slacks. This was Ferb Flecther. He walked over to where Phineas was and looked over the fence and saw two teenagers their age walk into the house next to them.

"Should we go say hi?" Phineas asked. Ferb pointed his thumb at their house and raised an eyebrow. "I know, I know. We have to finish getting ready for school tomorrow." Phineas said dejectedly. "Maybe I'll go say hi tomorrow then."

"Boys! Time for dinner!" a woman's voice called from inside. Phineas and Ferb left the fence and ran inside to eat. Inside was a woman with red hair setting down plates on the table. She wore a white shirt with a yellow tank top and khakis. She was Linda Flynn. At the table was a man with a white shirt with red cuffs and wore dark blue jeans. This was Lawrence Fletcher.

"Candace! It's time for dinner!" Linda called out.

"Coming Mom!" a voice called back. Down the stairs came another red headed woman with a long neck. She wore a red shirt and a white skirt with a red belt. This was Candace Flynn. She and the boys took their seats at the table and patiently waited for their food.

"Hey mom, did you know we have new neighbors now?" Phineas asked.

"No, no I didn't. How old did they seem?" Linda asked while putting food on the plates. Phineas took a bite before continuing.

"Well, I only saw the two teens. They looked like they were our age." he told her. "We're planning on introducing ourselves tomorrow."

"That sounds like a wonderful idea. By the way, do you two have your stuff ready for tomorrow?" she asked.

"We're almost done. We just need to sort out our e-notebooks." he answered.

"Well, make sure you finish before you go to bed." she said. Phineas and Ferb got out of their seats and put their dishes away.

"Ok mom, we will!" he called out before running upstairs.

In ?

Well,well,well. It seems that fate has brought these two sides together. I wonder what will happen when they finally meet? Looks like I'll see tomorrow. But for now, I'll buy my time. And when my time comes, I'll make sure to enjoy this. Looks like Shooting Star, Pinetree, and Halfheart are going to go through a big change…

And there we go folks! The beginning to The Halfheart and the Pinetree. If you enjoyed, make sure to Review, Follow, and Favorite! And as always,
