Chapter 01: Summerween Fest.

High School finally ended for the Powerpuff Girls and their friends, the construction of the home in which they will all live together while they're in college was already in progress.

However, they've got plans for Summer Break.

They will all travel to a place called Gravity Falls, a place who Dipper and Mabel used to visit a during their Summer Breaks in their past.

Since Phineas and Ferb were planning to make a music festival in the town to help Bubbles' band reach become more popular. This festival would be called: Summerween Fest.

But some people had their own reasons to visit the town.

Determined to learn about how Professor Utonium made them, Blossom recalled the letter in which he told him about Gravity Falls for herself, she hadn't even mentioned it to her head shrink.

Who were the people that Professor Utonium is so scared about?

Curiously, Blossom asked herself, unaware that somebody else was investigating the matter, about the group known as The Blind Eye Society.

Making the bags, Dipper hid his investigations and notes and his journal deep in the bag, so Mabel wouldn't find them.

Other people also got ready for the trip.

Among them was Corey Riffin, which was currently helping Bubbles' band Chromotopia write their songs, therefore he was invited to the trip to Gravity Falls, bringing with him, Trina's journal.

Since Trina wrote last that she dreamed with the town.

After school, The Powerpuff drop by Phineas and Ferb's home, they were preparing the vehicle in which they will all go.

Apparently, Mayor Jones gave them his own vehicle called 'The Mystery Machine', since the murder of Velma Dinkley, he decided to get rid of the van since it brought painful memories to the Mayor.

Obviously, when The Powerpuff arrived they weren't surprised to see that Phineas and Ferb maybe made too much upgrades to the vehicle.

Now it looked like the greatest camper in the world.

Impressed Bubbles said.

"Whoa…"

Then Blossom sighed.

Finally Buttercup said. "Figures."

"Hey guys." Blossom said and Phineas and Ferb turned around and smiled.

Walking forward Phineas cleaned his hands from the grease and the oil. "Good to see you guys, we're going to give the last touches to the Mystery Machine and we will all go in the morning, like it?"

"Don't you think you might exagerate a bit too much?" Blossom asked nervously.

"Nah." Ferb said.

"Haha, it's alright, we can all fit in there now." Phineas said.

"Maybe you should take a break guys, how about going to Hey Arnold's later?" Blossom said and Bubbles noddes.

"Right, our threat!"

Looking at Ferb, then Phineas smiled when Ferb gave the thumbs up.

"Alright guys, think we could use a break."

"Can't thank you guys enough for the music festival thing." Bubbles commented.

"Wanna hear who will be there?"

Then Bubbles asked smiling. "Please?"

"Rock Zilla, Hi Hi Puffy AmiYumi, Love Handel, Hotel Transylvania, among others, we're still unsure if the others can make it." Ferb said.

"Oh wow nice!"

"We're going to take a shower then." Phineas said. "See you at the burguers?"

"Kay, we're going to do the same." Blossom said and then the three left into the air, flying towards their house.

After taking a shower and dressing up, The Powerpuff arrived at Hey Arnold's where all of their friends were there.

Celebrating that High School was over for them, smiling the Powerpuff saw Phineas and Ferb arriving later on, with the Mystery Machine, surprising everyone in the restaurant.

"Wow, you guys at least showered?" Bubbles asked since they noticed that the Mystery Machine had a few more things than the last time they saw it.

"We did shower don't worry! Haha!" Phineas said.

"Like what we did?" Ferb asked as he stepped out of the Mystery Machine.

"Nice." Bubbles said.

"So guys, assume you did enough on it, can you take a break now then?" Blossom asked.

"Think it's ready, we can party now." Phineas said as he stepped down aswell.

Commenting, Dipper said. "Hey dude, that thing looks sick."

Shaking hands, Phineas chuckled. "Thanks man."

The group then turned around when Mordecai raised his voice.

Silence ran accross the room before Mordecai said. "Finally made up my mind guys! I'm going back to college!"

"Really?!" Maggie asked surprised.

"OHHHHHHHHHH!" Mordecai laughed. "That's right! I've earned enough money at the park so, well I guess I'll be seeing you guys there!"

"Nice!" Phineas said and all began to clap while Mordecai bowed.

"Thanks dudes! Now let's party!"

Practically the whole restaurant was partying, most of the clients were their group, so when Arnold finally closed, he didn't mind if they continued celebrating.

They watched the news, since Black White's attack on the city, Zim was put on trial several times, some had different opinions about what could they do with a outsider such as Zim in the end they all decided to be put on the highest security prison of Megaville: Foster's.

Something that was rather controversial.

So Zim was now a resident in Foster's Asylum.

Soon enough, Blossom went to talk with her sisters, Bubbles was in a alone table with Boomer, since they were dating, Blossom decided to leave her there and went to ask Buttercup who was talking with Dipper, Mabel and Mordo.

"Hey Buttercup, gonna go home now, you going to stay?"

"Of course, it's too early man, why don't you stay?"

"C'mon Blossom chill, we're going to the Park later and have some beers, wanna come?" Mordo asked.

"No thanks. Too tired, I'd recommend you to take it easy if we're going to travel in the morning." Blossom said, sighing about the mention of alcohol.

"It's alright, don't worry, thanks for worrying but we'll be fine." Mordo said and they all waved when Blossom left.

Finally arriving, Blossom went to check on Brandy's room, they agreed to bring Brandy with them on the trip since she wanted to be at the music festival.

Hearing a whisper, Blossom turned around in the hallway.

"Blossom…"

Then Blossom felt a chill down her spine. "Who's there?"

"Three letters back, three letters back, three letters back, three letters back…"

Suddenly, Blossom tried to cover her ears.

Hearing the same thing over and over, Blossom felt like she was going insane until she finally heard silence and she went into Brandy's room who was sleeping peacefully.

Next on the table, Blossom noticed the pin that Miss Grey gave to her, according to her, it would help her sleep, the cartoonish triangle's name was Bill and he would watch her in her sleep.

Lightly disturbed, Blossom pulled up the covers on Brandy who smiled.

Then Blossom stepped out of the room and heard the whisper again.

"Three letters back…"

Trying to ignore, Blossom went to her room and brought some clean clothes out to place them on her bed, she grabbed her towel and walked out to take a shower.

The only thing on her mind was that they would travel to Gravity Falls soon. Whatever, would she find there?
