Chapter Text
Phineas woke up to find himself in his backyard. He wasn’t alone either since Ferb, Candace, Stacy, Jeremy, Baljeet, Isabella, Buford, Vanessa, her dad…oh, hey! There was Carl and his dad too. He hadn’t seen them since they’d met. There was also Fireside Troop 46231, and finally…
“There you are Perry.”
The platypus made his classic chattering sound.
“Uh…Carl? How did we end up in Flyn-Fletchers’ backyard?”
“I don’t know, sir.”
The two men from OWCA looked at Doofenshmirtz.
“Don’t look at me. I didn’t do this. At least I don’t think I did. And if this is my fault, it wasn’t intentional. My New Year’s resolution was to give up evil for good-Wait a minute! New Year’s! Where’s all the snow?!”
Everyone looked around to see that it was a summer day. Which was weird because last night was New Year’s Eve.
Candace narrowed her eyes at her brothers.
“Alright, what did you do?” she said, crossing her arms.
“I don’t think we did anything. Ferb?”
The green haired boy shook his head.
“Then why is it summer all of the sudden?! And how did we all get in our backyard?!”
“This isn’t the backyard,” they heard Isabella say. She was standing in the tree, frantically looking in every direction.
“How can you tell, Isabella?” Phineas asked, not even doubting her for a moment.
“Because the rest of Danville is gone!”
“What?!” everyone present shouted.
Vanessa immediately opened the gate and saw that there was nothing but blue sky beyond the front yard. Not even the ground.
Everyone was silent.
“…Okay, just to be clear, I did not do this,” Heinz said.
Dipper woke up with a groan.
“Mabel? You there?”
“Dipper? Yeah, I’m…Back in the Shack?!”
“Huh?!”
They looked to see that they were not on the bus like they were when they fell asleep, but in the Mystery Shack’s living room. With them were Stan, Ford, Soos, Wendy, McGucket, Candy, Grenda, Pacifica, Nate, Lee, Robbie, and Tambry. Oh, and Waddles.
“Kids?” Stan asked. “What are you two doing here?”
“How did we get here?” Robbie cut in.
Ford pulled out a scanner and pressed a few buttons. The arrow on the meter immediately went to the red zone and clicked rapidly.
Fiddleford caught a glance and gasped.
“Sweet sarsaparilla! There haven’t been readings like that since Wierdma…Never Mind All That!”
“Uh, guys? Look outside,” Wendy said in an uncharacteristically fearful tone.
Dipper opened the door and froze upon seeing an endless void of red and purple. The colors from Wierdmageddon.
Pacifica, who was standing right behind him, let out an eep and clung to Dipper for dear life.
The boy closed the door and turned to everyone.
“Okay, so nobody go outside and we’ll be fine.” He turned to Pacifica. “You can let go of me now.”
Pacifica’s face blanched and she let go of him before clearing her throat. Mabel saw this and quirked a brow.
“Sixer, any idea what’s going on?” Stan asked his twin.
Ford shook his head.
Anne woke up to feel two weights on top of her. She opened her eyes to see that they were Sasha and Marcy.
Why is it getting hot right now?
The two opened their eyes and immediately got off their friend. Sasha cleared her throat while Marcy looked away to hide her blush.
Anne looked around and gasped.
She was back in the Plantars’ house!
And there they were.
“Sprig! Polly! Hop Pop!”
“Anne!”
All three of them hopped right for her and tackled the teenaer in a hug.
“Lieutenant?” Shasha heard from behind. She beamed upon seeing Grime.
“Grimesy!” she pulled him into a tight hug.
“Olivia! Yunan!” Marcy exclaimed after seeing them. She tried to embrace them both, but tripped over her feet and fell to the floor. “I’m okay.”
“Anne? Where are we?” Oum asked her daughter. Her husband had the same question.
“Why this is our home,” Hop Pop answered. “Please sit down. The couch is quite comfortable.”
The Boonchuy girl looked around the room to see Sasha, Marcy, her parents, Sprig, Polly, Hop Pop, Grime, Olivia, Yunan, Ivy, Maddie, Frobo, Mr. X, and outside was…
“Andrias?”
Everyone looked out the window to see the giant newt awkwardly waving to them.
“Uh…hello everyone. This is awkward. This might not be the best time, but it appears we are surrounded by miles of ocean with no land in sight.”
“What?!”
Sprig hopped through the window to see that the house was not in Wartwood, but a vast ocean.
“How did this happen?” Mr. X queried.
“The last thing I remember is walking through the portal,” Sasha answered. “Then everything went black and I woke up here.”
Anne gazed upon the ocean
“I don’t know what’s going on, but we’re gonna figure this out.”
Luz woke up to the sight of Amity hovering over her.
“Luz! Luz, wake up!”
The human yawned and stretched her arms before hugging her with them, eliciting a blush on Amity’s face.
“Good morning, Sweet Potato,” she said, nuzzling into her neck.
“Luz, as much as I am enjoying this, we have a serious problem.”
“Oh, come on, Amity. After what happened yesterday, it can’t possibly be that bad.”
“The Boiling Isles are gone.”
Luz immediately shot up and ran for the window in her room. She opened it and gasped in horror that the Owl House was surrounded by nothing but the Boiling Oceans for as far as the eye could see.
Noceda gripped her girlfriend by the shoulders and started shaking her.
“Where’s everyone else?! Are they okay?! Are they safe?! Did the Collector do this?!”
“Luz, calm down!” her girlfriend pleaded.
Realizing how rough she was being, the young witch did as asked and chuckled nervously.
“Sorry.”
“It’s okay. Everyone else is in the living room.”
The couple went down the stairs hand in hand and saw everyone else chatting animatedly. All their friends and family were there, including Willow, Gus, Hunter, Edric, Emira, Alador, Eda, King, Raine, Camilla, Lilith, Hooty, Hunter, Darius, Eberwolf, the Collector, and Vee.
Camilla ran up to her daughter and hugged her tightly. Then Stringbean slithered through the air and joined in.
“Mom, what’s going on?”
“We don’t know,” Eda answered. “But whatever it is, I don’t like it.”
King looked to the Collector.
“Hey, Collector, buddy, you didn’t do this, did you?”
The kid snapped his fingers with only little stars coming out.
“My powers aren’t working here. I don’t think we’re even in the Demon Realm.”
“Then where are we,” Luz asked.
“Everyone, look!” Hooty shouted, opening his door.
Suddenly, a door appeared outside. But it wasn’t just any door.
Luz gasped.
“The Portal Door!” She ran right for it and opened it up to see…a movie theater? “Huh?”
Then a letter appeared and was caught by Amity, who began to read it aloud
“Greetings people from the Boiling Isles. I understand that you are scared right now. But please stay calm. You are in no present danger. You are also wondering where you are…”
“…You are all in a junction of dimensions, replicated in the form of your home. It will expand to form the entirety of the towns you came from. I have only made it as such so that you may understand your situation better…” Phineas read to the Danville group.
“…A friend of mine has aided me by pulling you out of your respective dimensions and will return you at the exact moment you left when we are done here. As to why you are all here…” Dipper read to the people from Gravity Falls.
“I’m not overselling it when I say that the fate of everything depends on you,” Anne paused, exchanging worried glances with the Amphibia group. “This situation spans multiple dimensions across different times. I have selected each person and each group because I believe that you will help each other in ways you cannot imagine. For starters, you have more in common than meets the eye…”
“…But why waste time explaining this to you when I can simply show you. This place functions like a mindscape. So we shall be reviewing your past experiences so that you may better understand each other. A door will appear if it hasn’t already. There is a movie theater on the other side. And your pasts have been formatted into shows with episodes and seasons. Makes things easier. Name gags will appear on each person to signify which episode they may join the main room, upon finishing this letter. And tv’s will be in each group’s room so the others may watch as well,” Amity finished.
And just like that, the name tags appeared.
“What do you make of this?” Lilith asked Darius.
The Head of the Abomination Coven rubbed his chin in thought.
“Given the fact that the room is there, and that we don’t seem to have any other choice, it’s best that we play along. But be on guard.
Everyone nodded.
Luz looked down at her tag.
“Well, looks like I’m in the first episode. Later taters!” she said before kissing her girlfriend on the cheek and walking away, with Eda and King following her out. Amity’s face looked like a tomato.
“Do you ever get bored seeing her face like that?” Gus questioned Willow with a smirk.
“Not at all.”
“Me neither.”
The theater was silent. There were four doors in the back. They were all replicas of the ones from the Backyard, Mystery Shack, Plantar Farm, and the Owl House. Those door then opened and out came today’s viewers. From Danville were Phineas, Ferb, Candace, Isabella, Perry, and Doofenshmirtz. From Gravity Falls came Dipper, Mabel, Stan, Soos, and Wendy. Out of Amphibia walked in Anne, Sprig, Polly, and Hop Pop. Finally from the Owl House came Luz, Eda, and King. The various individuals began to mingle and exchange names. At least, after the initial surprise of talking frogs.
“Woah! Dude, your head! It’s shaped like a triangle!” Soos exclaimed.
Phineas chuckled.
“Yeah, I know.”
“Cool.”
Stan blinked upon seeing the boy. Then he frowned. I just hope he wasn’t picked on like Ford.
Anne stopped short when she saw Stan.
“Uh, guys? Is it just me, or does he look like the Curator?” quietly and breathless.
“It’s not just you, Anne,” Sprig answered, equally worried.
“Oh my gosh!” Everyone turned to see Mabel pick up Perry and King and hug them. “You two are so cute !”
The platypus just growled, not particularly minding the action. King however, squirmed and tried to push her arms off of him.
“No! Not again! Eda! Luz! Help me!”
His two family members just laughed.
The same could not be said about the Gravity Falls crew, though. They all froze, even Mabel, because that voice sounded a lot like…
Bill, Dipper thought. But it couldn’t be. Stan and Ford erased him.
Mabel immediately put Perry and King down and backed away, causing Eda to raise an eyebrow.
“What’s got all of you so nervous?”
“Nothing to worry about,” a disembodied voice spoke, gaining everyone’s attention. “Greetings. I am your host. And before we begin there are a few things to clarify. As all of you are aware, there exists the Multiverse, made up of infinite Timelines. Timelines are typically made up of multiple Dimensions, or Realms, but time flows the same. Some of you come from a different Dimension but all exist on the same Timeline. In fact, all the humans brought here are from the same Dimension of Earth. But each group has been pulled from a different point in the Timeline. The Gravity Falls group is from 2012. The Danville group is from New Year’s Day in 2013. The Amphibia group is from early 2020. Finally the Owl House group is from November 2020. And in order to prevent any problems with the Time-Space Continuum, a portion of your memories gained here will be forgotten until November 2020. I also ask that you please don’t spoil what happens in your ‘shows,’ or I will have to use a silencing spell.” Everyone looked at each other and nodded. “Good. We will be watching roughly three ‘episodes’ of each ‘show’ a day in chronological order. Sometimes it will be six half length episodes.”
“So that means our show is first?” Heinz asked.
“Yes.”
“Which episodes are we watching today?” Phineas questioned.
“Rollercoaster. Fast and the Phineas. Lawn Gnome Beach Party of Terror. Flop Starz. Get That Bigfoot Outa My Face. Tree to Get Ready.” The ones who understood what those titles meant smiled fondly. Those were some good days. “Keep in mind that since your group has had so many adventures that for the sake of time, not all of them will be covered. But you are more than free to talk about them during the breaks. Oh, and before I forget, you have lost some memories, but I shall restore them.”
Perry’s eyes widened in alarm.
“What are you…” Phineas trailed off, holding a hand to his head and groaned. The rest from Danville began to do the same thing. Then a metaphorical dam burst inside their heads and everything came back. Traveling to the 2nd Dimension. Meeting the other Doofenshmirtz. Learning Perry was a secret agent. The battle in Downtown. Agreeing to forget that day. Then there was something else, but they couldn’t remember what.
Phineas and Ferb looked down at their pet with wide eyes. He looked back at them nervously. Then they smiled fondly and started petting him.
“Water under the bridge,” the triangle headed boy whispered. “Right Ferb?”
Ferb gave them a thumbs up.
Candace just blinked.
“I still have so many questions. Like what’s that last thing I can’t remember?”
The others nodded in agreement.
“Well, that last memory would be a spoiler for a certain someone in your group. And I do not think now is the time for them to know. Anyways, everyone get seated, and let us begin.”
