Emotional me: Let's write a Phineas and Ferb fic!
Logical me: Don't you already have a bunch of WIP already?
Emotional me: So?
Logical me: ...continue.

It's been ten years since one of the most funniest and heart wrenching movie of my childhood released and I'm going to write a fic about it! And no one can stop me!

----------------------------------------

It’s the first day of a new summer and the Flynn-Fletcher brothers were sitting under their tree, ready to seize the day. 

“First day of summer, Ferb. How are we going to make the most of this summer?” Phineas asked. Ferb shrugged, reading his book. “Well, we have to think of something! Remember last summer? We have to do even better.” 

Silence reigned as they thought for a moment. “I got nothing. Maybe Perry knows what to do.” Phineas said, looking around, only to find the monotreme missing. “Hey, where’s Perry? Does it seem like Perry’s comings and goings are even more random nowadays?” he asked. 

“Alright, dweebs. What have you planned for this summer?” Candace asked, coming out of the house. “Dancing mermaids? Flying pigs? Castle on a rainbow?” 

“Haven’t decided yet but those are all great ideas.” Phineas said. 

“Well, you can go do whatever you want, as long as it doesn’t mess with my job.” Candace said. “I need some extra money and I don’t want you two to mess it up for me.” 

“Why would you need extra money?” 

“None of your business!” Candace turned, ready to walk away when suddenly a portal opened up in front of her.

“Phineas… what’s going on.” She asked, backing towards them and away from the growing portal. 

“I don’t know Candace. We weren’t planning on making any portals.” He said, holding tightly to Candace’s and Ferb’s hands. He didn’t know why but he had a feeling portals aren’t always a good thing, especially unknown ones. 

The portal suddenly stopped growing and a box was thrown out of it. Just as the box touch the ground the portal closed. The three of them stood in silence, not knowing what to do. 

“What do you think it is?” Candace asked. 

Phineas and Ferb shrugged before Phineas moved closer to it. “I’ll open it.” He said. 

“What! No! What if it’s a bomb or something?” She exclaimed. 

“Well, we won’t know until we look. And besides, Ferb knows bomb disposal.” 

“You do?” Ferb nodded. 

Phineas carefully moved towards the box, not making any sudden movements. When it did not blow up he carefully opened the lid, letting out a sigh when nothing blows up or jumped out of it. He looked inside to see a bunch of DVDs. A closer look made him smile. 

“Hey, guys! Come look!” Candace and Ferb looked over his shoulder to see a bunch of cartoon DVDs. But what caught their attention most was the characters in it. 

“Is that… us?” Candace asked looking at the cartoon version of herself. Her long neck seems even more exaggerated in the cartoon. 

“There’s a letter.” Ferb said, giving it to Phineas. He opened it and started reading. 

Dear Phineas, Ferb, and Candace,  

There are some secrets that you guys need to know as well as some injustices that were done to one of you. These are the days of your best summer yet, made in cartoon form. I want you to gather the people on this list and watch it together.  

·        Linda  

·        Lawrence  

·        Isabella  

·        Baljeet  

·        Buford  

·        The Fireside girls  

·        Jeremy

·        Stacy   

·        Vanessa  

By the end of watching this, you guys will discover a lot of things.  

“Stacy, Jeremy and Vanessa? I mean, I get the others, even Stacy and Jeremy. But why Vanessa?” 

“Who knows,” Phineas said with a smile. “but I do know what we’re gonna do today.” 

--------------------------------------------

“So you’re saying this came out of a portal?” Vanessa asked after she got to the Flynn-Fletcher house. She had got a call from Candace to get as fast as possible. “And it had all our names and instructions to watch it together?” 

“Basically, yeah.” Phineas said. 

“Oh, you guys have such an active imagination.” Linda said, setting up refreshments for all the kids. She didn’t know what the boys have planned, only that they were going to watch the best summer of their life. She figured it was homemade videos they made with Irving’s help or something. 

“Oh, you’ll see mom. It’s all real.” Candace said taking her seat next to Jeremy, ready for the show. “And now I have actual proof. Soon everyone will see that I was right!” 

“Down girl.” Stacy said, popcorn in hand. Vanessa came and sat next to her and soon everyone was seated around the TV. 

Ferb put the DVD in and press the play button. 

The first thing on the screen is a tear-off calendar showing the date to be June third. Pages start flying off into the sky before the view moves back down, through a tree, to show Phineas, Ferb, and Perry in front of said tree in their backyard.

“Oh, it’s a cartoon! How cute!” Linda said, watching the cartoon versions of her boys. “How did you make it so good?” 

“We didn’t mom.” 

♪ There's a hundred and four days of summer vacation, then school comes along just to end it. ♪

♪ So the annual problem for our generation is finding a good way to spend it. ♪

“Hey, It’s our theme song Ferb!” Phineas said, pointing at the screen. 

“You boys have a theme song?” Linda asked curiously. 

“Yeah! We made one last summer. Love Handel sang it for us.” 

“Oh, isn’t that interesting Lawrence. The boys are making original music." 

“I don’t see how you’re surprised Mom. They were one-hit wonders last summer.” Candace said. 

“Oh, such imagination.” 

♪ Like maybe ♪

♪ Building a rocket, or fighting a mummy,  ♪

♪ Or climbing up the Eiffel Tower; ♪ 

Very briefly it showed Phineas conduct while Ferb and four penguins play a trumpet riff.

♪ Discovering something that doesn't exist ("Hey!")  ♪

♪ Or giving a monkey a shower.  ♪

Now Ferb and two penguins have switched to guitar, while a third is on drums.

“Well, that’s a rather unusual list.” Lawrence commented.

♪ Surfing tidal waves, creating nanobots, ♪

♪ Or location Frankenstein's brain ("It's over here!") ♪

♪ Finding a dodo bird, painting a continent, ♪

♪ Or driving our sister insane. ("Phineas!" yells Candace from inside a picture frame) ♪

“So you did know you were driving me insane!” 

“It was just to rhyme, Candace. We didn’t actually mean it.” Phineas with Ferb nodding behind him. 

In the background Phineas and Ferb are seen directing a movie, operating a giant robot dog, building a racecar in the garage, sitting in a rollercoaster car as it re-enters the earth's atmosphere, and finally pushing an elephant across the backyard in a wagon.

♪ As you can see there's a whole lot of stuff to do before school starts this fall, ("Come on, Perry!") ♪

♪ So stick with us 'cause Phineas and Ferb are gonna do it all! ♪

Candace angrily tries to hit much smaller versions of Phineas, Ferb, and Perry as they keep popping out of an arcade game called "Whack a Pest!"

“Now that is something I can believe.” Linda said, causing Candace to go red. 

Finally, while stopped-frame scenes move across the background too fast to really tell what they are in detail, Phineas and Ferb dance in the foreground, Ferb shredding away on a guitar.

♪ So stick with us 'cause Phineas and Ferb are gonna do it all! ♪

Candace walks in. "Mo-om! Phineas and Ferb are making a title sequence!" 

“Oh, this cartoon has you right on spot.” 

“MOM!” 

The boys glance at each other, then give one final guitar chord. 

“Boys, that song was great. You two should look into the music industry.” Linda said, remembering her Lindana days. 

“Nah, been there, done that. We’re more interested in inventing.” 

The scene opens up with the camera zooming into the backyard. Phineas, Ferb, and Perry are sitting under the tree’s shade.  

“So, Ferb, what do you wanna do today?” Phineas asks unenthusiastically and Ferb shrugs in answer. 

Buford starts laughing as soon as he hears Phineas’s voice. 

“Oh, man! What’s wrong with your voice, dinnerbell?” he laughed. 

“I didn’t think my voice was that high. Or that… squeaky.” 

“Don’t you remember Phineas? Your voice dropped last summer.” Candace said. “Good thing too. Your voice was horrible.” 

“What about Perry? What does he want to do?” Perry chatters, mindlessly. “Well, he's a platypus. They don't do much.”  

“Yeah, I think you just might start thinking differently after this.” Vanessa said, having figured out what the secret told in the letter is.

“I, for one, am starting to get bored, and boredom is something up with which I will not put!” He continued. 

"Well, I think you sound perfectly lovely" 

“Thanks, Isabella!” 

“The first thing they're gonna ask us when we get back to school is "what did we do over the summer?". I mean, no school for three months. Our life should be a rollercoaster! And I mean a good rollercoaster. Not like that one we rode at the state fair...”  

Flashback to the rollercoaster at the state fair. It goes over one tiny hill then ends. “Please exit to the left.” The fair worker said and the flashback ended.  

“That’s how you came up with that idea?!” Candace asked, surprised. 

“Yeah. How do you think we did?” 

“Man, that was lame. Why, if I built a rollercoaster, I would-“ Phineas suddenly gets an idea and an angelic chorus plays. “That's it! I know what we're gonna do today!”  

“And there’s the iconic line.” Candace said, tired. 

“Phineas, Ferb.” their mother, Linda calls out. “I'm gonna pick up a few things. You boys stay out of trouble, okay?”  

“Honey, you look absolutely beautiful in 2 dimension.” Lawrence said. 

“Thank you, dear.” 

“Okay, Mom.” He says before turning to Ferb. “We're gonna build a rollercoaster!”  

“Didn’t she just say not to get into trouble?” Jeremy asked. 

“But we didn’t get in trouble, though.” 

“Ain’t that the truth.” Stacy said, next to a sulking Candace. 

As Linda gets into the car, Candace comes out of the house. “I'm in charge, right? You did tell them I'm in charge?”  

“Relax, Candace, nobody has to be in charge.”  

“But Mrs.Flynn-Flecther, don’t you always leave Candace in charge.” Baljeet asked. 

“Only because it’s quicker to agree.” 

“But what if there's an emergency?”  

“Like what?”  

“What if a... What if a satellite falls out of orbit and crashes into the house?” Candace asks, before smiling innocently.  

“If that happens, you're in charge.” Linda said, fed up.  

“Yes!”  

“Didn’t that happen once?” Holly whispered to Milly. 

“Mom says I'm in charge, conditionally.” Candace announced as she entered the backyard.  

“Whatever.” Phineas said, not listening. He and Ferb seem to be working on blueprints, with Perry lying under Phineas’s table. 

“Wow, you two a really invested in your play rollercoaster.” Linda said, looking at their workstation. 

“That’s because it’s not a play rollercoaster mom! It’s- you know what, never mind. Just watch the show.” 

“Wait a minute, what are you doing?” she demanded.  

“Homework.”  

“Hey, why did you lie that time?” Candace asked. Normally they have no problem telling about their inventions. 

“I, eh… I don’t actually remember. Ferb?” Ferb shrugs.

“It's summer.”  

“That's cool, you wait till the last minute then.”  

Candace’s eyes narrow in suspicion. “Well, I'm watching you.” She walked through the door, sticking her head one last time. “And I'm in charge—conditionally!”  

“Boys, even if it’s something minor like this, you shouldn’t lie about it, okay?” 

“Okay. Sorry, mom.” 

The phone rings from inside, which she answers. “Hello? Oh, hi, Stacy! No, I can't get to the mall right now. Mom just went to the store, she left me in charge, well, you know, conditionally.”  

She talks, oblivious to Phineas and Ferb, who walk past with lots of wooden planks.  

“That’s a lot of wood for a play rollercoaster.” Linda said, frowning. 

"Well, wood's only good for the track cross-planks, but even so you need a lot." 

"Exactly how big was this rollercoaster?" 

“We made it all over Danville!"

“And if you go, can you see if Jeremy is there? No, no, he's the cute one that works at Mr. Slushy Burger.”  

“On, you had a crush on me from way back then?” Jeremy teased.

Phineas and Ferb walk past again, with steel beams.  

Linda’s frown intensified. She was suddenly worried about what the show was showing. She knows she should just dismiss it as an exaggeration. There’s no way her boys could have build a real rollercoaster on their own. But the self-assured way Phineas was talking was making her very nervous. 

“Oh, man! I can’t believe I missed this!” Buford yelled angrily. 

“Didn’t you ride it the second time they made it?” Baljeet asked. 

“Yeah, he totally smiled at me the last time I was there. I just about died. No, I told you I can't, I'm watching my brother and stepbrother.”  

Phineas and Ferb walk past with sinks and toilets.  

“Wait, you made it twice?” Linda asked, suddenly feeling scared for some reason.

“Yeah! The second time was a musical.” 

“Yeah, and they never get into trouble, 'cause Mom never catches them. One of these days though, I'm going to see that she catches them red-handed.”  

Phineas and Ferb walk past again, with a flamingo and a lion roaring loudly.  

“Why would you need a lion?!” 

“We thought it would have been a great jump scare but don’t worry mom, we scratched it out when we figured out how dangerous it was.” 

“Oh, and a rollercoaster isn’t considered dangerous?” Candace asked sarcastically. 

“Will you hold it down, I am trying to use the phone!” Candace yelled out before going back to her call. “Mom left me in charge, so there will be no shenanigans today. What are they doing right now? Why do you ask?” she asked confused. “What do you mean you can see it from your house? See what?!”  

Candace runs out to the backyard and stares in shock and horror upon seeing the rollercoaster. 

“That’s strange. None of our safety precautions are being shown.” Phineas said looking at how the rollercoaster was depicted. 

“Well, it is a cartoon.” Ferb replied. 

“Yeah, I guess.” 

“Phineas, what is this?!” she asked in a panic.  

“Do you like it?” he asked back, excitedly.  

“Boys, don’t tell me you actually rode this?” Linda asked in distress. 

“Yeah! We even let others ride it.” 

“Linda, are you all right, dear?” Lawrence asked at his wife’s pale face. 

“Ooh, I'm gonna tell Mom, and when she sees what you're doing, you are going down!” she yells in anger, walking away. “Down! Down! Down! D-O-W-N, down!”  

Phineas and Ferb look blankly while she walks away. “We're gonna need a blowtorch and some more peanut butter.”  

“BLOWTORCH?” Linda screamed. “WHY WOULD YOU NEED A BLOWTORCH?!” 

“We kind of need it to weld the metal, mom.” Phineas said, slightly scared at his mother’s outburst. 

“Aren’t you two a little young to be using a blowtorch?” Vanessa asked. 

“Not really. Ferb’s certified for it.” 

At that Linda just lay back against the couch, shock and disbelief clear in her face. 

Meanwhile, Candace could not believe this. Her mom was finally seeing Phineas and Ferb’s inventions. 

“Calm down girl.” Stacy said, seeing the glee in her friend’s face. 

Candace takes her bicycle and rides away, not noticing the girl walking towards her.  

“Hey Candace, is Phineas... home?” Isabella asked, but gets ignored by Candace who’s peddling fast to reach her mother.  

“Down, down, I say!”  

“Wow. And I thought you are high-strung now.” Vanessa said. 

“Girl, this is nothing.” Stacy said. “You should have seen her when she was 10.” 

Isabella walks into the backyard, hearts in her eyes. “Hey, Phineas.”  

Isabella suddenly tensed at the scene.

"Umm…why are there hearts in Isabella's eyes?" Phineas asked somewhat awkwardly. 

Phineas, now on ground level and rooting around in a chest, waves and replies "Hey Isabella" but clearly not with much attention.  

“That’s standard practice in cartoons, Phineas. It means she's deeply in love!" Lawrence answered. 

“But-but Isabella doesn’t like me, right?” he asked, turning to his friends. 

“What'cha doin'?”  

“Building a roller coaster.” Phineas said distractedly, looking in his toolbox for something.   

“You are kidding, right? You do know she has a giant crush on you for ages, right?” Baljeet said. 

“Uh...no...” 

“In your backyard?”  

“Some of it.”  

“Oh, come on! It was so obvious! She-“ 

“Okay! Let’s not talk about this right now!” Isabella said, covering Buford’s mouth. “We might miss something important if we keep talking.” 

“Or, we could pause it.” Ferb said, pausing the cartoon. He was tired of his brother being so oblivious and he was not letting this chance go to waste. 

Isabella looked scared as everyone looked at her, including Phineas. Her heart beat faster, and her knees felt weak. She couldn’t do it here. 

“I-I just realized that I, uh, I need to help my mom with something. You guys watch this, I’ll watch later, bye!” She ran out of the house quickly, not bothering to look back at Phineas who called out to her. 

Phineas watch as she ran to her house next door. He wasn’t sure what he was feeling but he knew he didn’t like leaving things unsaid like this. He turned towards his friends and family. 

“You are absolutely hopeless in romance.” Candace said, with her arms folded. 

“In fairness, he is only 10.” Jeremy said.

“I don’t get it. Why didn't you guys ever tell me?” Phineas asked. 

“We are boys. We do not talk about feelings.” Baljeet said and Buford shrugs in agreement. 

Phineas turned to the Fireside Girls to see them avoiding his eyes. “It’s girl’s code, okay! We can’t tell if a girl is crushing on a guy.” Gretchen said finally. 

“I-I don’t know what to do.” Phineas said sadly. Did he just lose a friend because of his ignorance? 

“Look, I’ll help out with your love life later. Right now she needs time and space.” Candace said, seeing how pathetic her brother was being. “For now let’s watch this thing.” 

“Thanks, sis.” Phineas sat next to Ferb, who patted him on the shoulder. 

“That was really nice of you, Candace.” Stacy complimented. 

“Yeah, yeah. I just want it to be over so that they’ll be busted soon.” 

“Of course it is.” 

Isabella turns to the rising construction and gazes in awe. “Wow. Isn't that kind of impossible?”  

“Some might say.” Phineas says, almost amused.  

“Hey, Ferb.” Isabella calls out and waves. Ferb waves back with the hammer in his hand.  

“Wait a minute.” Linda said suddenly. “If you started making things last summer, then how is Isabella not questioning this?.” She asked, her worries increasing. She had never had a complaint from school about the boys but if what she’s seeing actually happened, then that means many others know about her boy’s inventions and never bothered to tell her. 

“Well, we always build things, just not that high scale. And we kind of started early that summer. We taught monkeys to juggle bicycles, and Isabella and the Fireside Girls helped out. So she and the others kind of knew we were going to be doing something fun."

Linda remembered her daughter telling her about something like that. But she had never seen any of this. Not the monkeys and definitely not the rollercoaster. ‘But they just said that they did it. What am I suppose to think about all this?’ 

“Does your stepbrother ever talk?” she asked curiously.  

“Ferb? He's more of a man of action.” Ferb hits the nail with the hammer and it ricochets back, hitting his nose.  

“I was gonna go to the pool, you wanna go swimming?” Isabella asks.  

“Kind of in the middle of something here.”  

“Oh, right. Okay, I'll see you later then.” She said before leaving. 

Phineas cringed. “Was I really that cold to her?” 

“You have changed a lot since the first day of last summer.” Ferb said. 

Phineas goes back to his toolbox, not giving her much notice. “Hey, Ferb! You got enough rivets up there?”  

Ferb gives a thumbs up and shoots three rivets into the wood, showing they have rivets.   

“Hey, where's Perry?” Phineas asks, looking around.  

“Right on schedule.” Candace said. 

Perry walks around the corner of the house, his eyes looking back for a moment. He jumps up, puts on a fedora, and clicks on a button on a remote. A door opens in the wall and a hole appears, into which he gets in.  

Stacy stiffens when she sees this. ‘Oh no! This is bad. They’re going to find out he’s a secret agent!’ she thought. 

“What’s going on? Why does Perry have a hat? And where is he going?” Phineas asked. 

“Maybe whoever sent this must have changed the story to fit him in the cartoon?” Milly said, hesitantly. 

The hole turns out to be a lift that goes down into a large room underground. A map hangs from one wall, control stations are set up all around the perimeter. A large talk filled with water takes up the opposite side of the room, and a comfy chair and side table with drink sits in the water. In front of one particular chair is a huge screen that says 'Incoming Message'. 

"Hey, isn’t that the room you built for us that day we were secret agents, Ferb!" 

"Look, for the last time, I didn't make any of the things we used that day" Ferb replied, irritated. 

“Wait, when did you two become secret agents?” Candace asked. “I don’t remember that.” 

“It was the day of your Betty tour. Maybe we will see it.” 

“Good morning, Agent P.” A man with a white mustache says as Perry clicks on the message. “The evil Dr. Doofenshmirtz is up to his old tricks. For reasons unknown to us, he bought up 80% of the country's tin foil.” Perry listens as he writes down on a small pad in his hand. “I want you to get over to his hideout right away. Find out what he's up to and put a stop to it.”  

“Wait, isn’t that your dad, Vanessa?” Candace asked, seeing the cartoon photo of Doofenshmirtz on Perry’s screen. 

“Yeah, he is.” 

“So, if he’s your father then that means this is all just a cartoon.” Linda said, suddenly relieved. “Perry isn’t a secret agent and Phineas and Ferb didn’t make a rollercoaster!” 

“WHAT?!” Candace yelled and Ferb paused the cartoon again. “Here is physical proof that they build it and you still don’t believe it!” 

“Candace, this is a cartoon. They’re not real.” 

Before Candace could blow up Vanessa took out her phone. “Sorry to break your bubble, Mrs. Flynn-Flecther, but it’s all real.” 

Her phone showed a group selfie. She was looking at the phone with a small smile, while her dad was behind her making a funny face. Behind them was a torso of a huge tuxedo-wearing man, his face not show. And between them, with his hands crossed and a fedora, was Perry with a small smirk on his face. 

“Perry is a secret agent. And Phineas and Ferb did make a rollercoaster. Along with some other things.” 

The room fell into silence at her words. No one knew what to say to that. That is until a small voice asked hesitantly. 

“But… if he was an agent, why did he never say anything?” Ferb asked. 

Vanessa seems to hesitate before she answered. “All I can say is he is not the only one who has to keep it a secret. All agents have to do it too.” 

“So what, we’re just a cover story for him?” Phineas asked suddenly enraged. “Just another stop for his job? I mean, was he ever really our pet or part of our family?” 

“Phineas-“ 

“No! I am done with all these secrets! I need some air.” He said, cutting Vanessa off and leaving the house. 

He walked out, not noticing nor caring where he was going. He walked and walked until he reached the park. He looked up to see the last person he would be seeing there right now. 

“Isabella?” 

Isabella turned, shocked to see Phineas there before her face showed resignation. 

“Hi, Phineas. What’cha doing here?” 

“Trying to figure out why everyone is keeping secrets from me.” He said, not noticing her flinch. 

“Is this… is this about not telling you about my feeling?” 

Phineas suddenly seems to realize his wording. “Oh! No, it’s not that! I mean, it’s a little bit of that? But it’s not like you have to tell me about it! It’s your feelings.” he rambled out before he stopped and sighed. “Perry’s a secret agent.” 

“…What?” Isabella asked, not sure if she heard him right. 

“Yeah, apparently he’s going out to fight evil all this time and we were just his cover story.” He said, scratching his head. “I can’t believe he never told us. Shouldn’t there be no secrets between family? Doesn’t he trust us at all?” 

The sounds of the children playing in the park washed over them as they sat in their own silence. After a while, Isabella finally opened her mouth. 

“Well, remember that day when you and Ferb were the Beak? And how you two didn’t tell me about it?” 

“Yeah….” Phineas said slowly, not knowing where she was going with this. 

“Why didn’t you tell me anything back then?” 

“We wanted to keep you safe, of course!” Phineas said before he figured out what he said. “B-but that’s different! Perry knows we can take care of ourselves.” 

“Oh, so you’re saying I can’t take care of myself?” she asked, acting offended. 

“No, that not what I’m saying at all! I just meant that- it’s just-" he finally stopped at Isabella’s amused look. “Alright, I get your point.” 

“Good.” She said, patting his shoulder. “I’m not saying that’s the only reason he kept it a secret, but I’m sure it’s not because he didn’t trust you.” 

Phineas seems to slump as her words finally registered through his feelings of betrayal. “Well, you’ve always been right before.” 

They both smiled at each other, but then blushed and looked away. Now that the main problem was solved there was a little problem of feelings between them that have to be solved. 

“S-so, Isabella. You have a crush on me?” 

“O-oh, yeah, I kinda do, yeah.” 

“Wow. That’s cool, I guess.” 

“Really? That’s all you have to say?” Isabella deadpanned. 

“W-well, I’m not really sure what I’m supposed to say or do. I don’t actually know much about romance.” Phineas defended, fiddling with his ear. 

“Gee, I didn’t notice.” Isabella said in the most expressionless tone. “Look, Phineas, it’s okay if you don’t like me back. I-“ 

“But I do!” Phineas said, interrupting her. “I do like you. I just- I just don’t know what to do now.” 

Silence fell again as his words registered in her mind. 

“…. I guess it’s okay that you don’t know. I mean, we are only 10. We have all the time in the world to figure it out.” Isabella said, standing up. She held her hand out to Phineas. “We can figure it all out together, starting from watching that cartoon and finding out who sent it to us and why.” 

Phineas smiled, taking her hand. “I would like that.”   

Part 2 coming soon!
