Work Text:

Summer: The time of the year that you don’t have to care for homework and projects and the perfect time for some crazy fun, which means the perfect time for Phineas and Ferb to make something super cool that will blow everyone’s mind.

-At the Flynn-Fletcher’s household-

“Oh Jeremy, I can’t wait to see you this Saturday!” Candace said on the phone.

“By the way where are you taking me? I mean it’s not that I really care as long as I’m with you, but you know I have to think about what to wear and- OH MY GOD! Jeremy I’ll call back. I love you, bye!”

Candace takes her head out of the window and screams. “Phineas and Ferb! What is that?!”

“Oh, well actually it’s a-“

“Don’t tell me, I don’t care!”

“But then why did you-“

“I don’t want to know, but what I do know is that you are going down. Down, down, down. D-O-W-N, DOWN!”

Candace closed the window and proceeded to find her mom as she was raging. Phineas and Ferb looked at each other and shrugged.

“Oh well, Ferb I guess we missed our chance. Now we have to find someone else to try it on and see if it works. I have an idea! Let’s try it on Perry! I never get to understand that platypus.”

Phineas looked around but no Perry in sight.

“Hey where’s Perry?”

‘Doo-bee-doo-bee-doo-bah
Doo-bee-doo-bee-doo-bah
Doo-bee-doo-bee-doo-bah
Doo-bee-doo-bee-doo-bah’

Perry walked to the side of the house and looked around to make sure no one was looking. He got up to his two feet and wore his fedora. He knocked at the house two times and an opening appeared. Perry slid in and ended up at the same chair he always did with Major Monogram at the screen.

“Morning Agent P, Doofenshmirtz is back in his game again, trying to cause evil to the Tri-State Area. Go Agent P and save the day.”

“Gyrururururuk” Perry saluted.

‘He's Perry
Perry the Platypus
(You can call him Agent P)’

Perry ran to his Platypus Mobile, turned on the engine and went on to Doofenshmirtz.

‘Perry
(I said you can call him Agent P)
Agent P’

-Back to Phineas and Ferb-

As the now teenagers are trying to find their first victim, a very familiar sound comes from a very familiar person.

“Hi Phineas, Whatcha doin’…?”

“Hi Isabell-… What happened? Why are you so gloomy and not, you know, not Isabelling?”

“Oh, it’s nothing, don’t worry. Just that, you know, Pinky has been acting weird lately. He seems kind of distracted and worried but I can’t seem to understand why…”

“Maybe he just wants to poop-poo?” Ferb suggested.

“No, I don’t think so Ferb… I already tried taking him for a walk but that was not it…”

Phineas eyes flashed for a moment. He turned to look at Ferb with a huge smile, then back to Isabella. “Mind taking a look? We have the perfect invention just for it”

“Sure, let me just get him.”

Isabella turns around to leave, but at that moment Baljeet and Buford enter the backyard.

“Hello Isabell-…” Baljeet greeted.

“Hello and bye!” She said quickly, rushing past them.

“Ooookay… So what’s up guys?” Buford asked.

“Oh well, you know, the usual. Just made something to try it out to Candace because she is on her…”
Phineas looked to around to see if any signs of Candace
“…period, just to be sure on when it’s a good time to talk to her and when it’s not. It can show your strongest feeling with colors. Cool, right? But she didn’t even let us talk, so we are using it on Pinky to see what’s bothering him!”

“Cool, i guess.” Buford shrugged.

-Back to Agent P-

‘Doofenshmirtz Evil Incorporated’

Perry entered the building and got into position to fight.

Nothing…

Weird.

As he took a step back he stepped on a button and a baby bed appeared from the ground locking him into place with some metallic holders and a robotic hand put a soother on his beak.

“HAHAHAHAHA Perry the Platypus, look how cute you look, just like a little baby.”

“Well, well, well, you see how I don’t give you a pillow? That’s because Agent P, I Dr. Heinz Doofenshmirtz, will turn every single pillow into a warm one. AHAHAHAHAHAHA.”

“You see Perry the Platypus, back to when I was still a young little boy, in a small village called Gimmelshtump in Druelselstein,…

-Flashback-

…every summer was always really hot and our house was so small, that all the heat was gathered at the second floor, which was my room! So every night I had to sleep on a warm pillow, while my brother had a cool one!”

-End of flashback-

“You see Perry the Platypus, life always tends to be unfair and it’s always to me, but not anymore!”

Doofenshmirtz pressed a button on a remote he was holding and a large weirdly-shaped machine emerged.

“Behold Perry the Platypus, the Pillow Heatinator! I know what you are thinking, couldn’t you find a better name? Well, I was going to name it something else but then I thought people wouldn’t…”

As Doofenshmirtz was rambling about his -inator’s name, Perry was trying to think about a way to escape.

He then remembered the button that the stepped before. Perry took advantage of the soother in his beak and spit it with all his might. The soother hit the ceiling then the wall and landed on the button on the floor, just like he intended.

The baby bed launched him toward Doofenshmirtz. Agent P stole the remote but accidentally pressed a button.

“HAHAHA Perry the Platypus, you might have thought that you would win this time but thanks to you, my Pillow Heatinator is now ready to fire! HA, did you get that? Because it is a heating machine and fire is hot and- and- and you know what, it’s not funny anymore… You won’t escape Perry the Platypus!”

-At Candace-

“Mom! Mom! Where are you?!”

“Candace sweetie, I’m working here. What is it?”

“You gotta see what Phineas and Ferb are doing!”

“Come on Candace, aren’t you and the boys a bit old to play this game anymore?”

“But mom! I’m telling you, they really built something crazy this time!”

Linda sighed.

“Okay Candace, then what is that crazy that the boys built?”

Candace paused. “It’s a… it’s… it’s a… I don’t know! But it is something! You gotta see it mom!”

“Candace sweetie, if you end up finding what that crazy thing was then I promise you I will go down to check it.”

“You know what, I’m gonna find what that thing was and when you see it you will beg me for forgiveness for never being me! Did you hear me, mom?! Beg me!” Candace screamed as she stormed out of the room.

-Back with the boys-

“I’m back guys!” Isabella entered holding a very recalcitrant Pinky.

“Isabella is your dog okay? I could smack it for you if you want to?”

“Buford no! Pinky is not a sandbag for you to hit!”

“Okay, okay, sorry for trying to help. Geez...”

“Well, guys instead of fighting how about we just use the Mood Meter, huh?”

“A what?” Isabella blinked. “I thought you were going to check on Pinky.”

“Oh we will, with the Mood Meter! Just wait and see Isabella. So first, go in front of the tree and hold Pinky steady, so Ferb can do his magic.”

Isabella did as Phineas instructed her, but the moment Ferb pointed the Mood Meter at Pinky, he jumped out of Isabella’s grip and it hit her instead.

When the boys realized what happened, they all went to the Mood Meter to see what color it appeared, except for Phineas, who immediately ran to Isabella, to see if she was okay.

The first color the machine showed was blue.

“Blue?” Baljeet asked, a little confused.

But then… as Phineas reached for Isabella’s hand to check if she was feeling weird or something, the blue started warming up until it became a variety of red shades.

“What the…” Ferb murmured, but then glanced knowingly at the two idiots-in-love-who-are-clueless-about-it-thought.

“Ferb, I think your little machine’s broken. What are all these reds? What are they supposed to mean?” Baljeet asked noticing Ferb’s smirk and the side-eye toward their two friends.

“Oh, so that’s what they mean…”

“HAHAHA wait until Phineas finds out that Isabella has such a huge crush on him that the Mood Meter can’t even pick one color!” Buford laughed, snatching the device from Ferb’s hands.

“Don’t you dare-“ Ferb growled to Buford as he started chasing him before he did something stupid.

“Guys, please! Stop! Buford! Ferb!” Baljeet sighed. “Just how in love are those two with each other to not even be aware of all this chaos around them? Hikes!”

-Back to Agent P-

Agent P started panicking. He started smashing buttons on the remote, but nothing worked. The Pillow Heatinator began glowing and screeching uncontrollably.
Agent P grabbed the steering wheel and trying to override the machine, but no outcome.

And that’s when it hit him. Agent P started running back into the building… into the WC.

“Perry the Platypus, where do you think you are going? You can try escaping me but I’ll always hunt you down! Oh- oh to the toilet? I guess, that makes the ‘always’ to a ‘most of the time’…”

Agent P entered the WC and started searching for something heavy. As he looked into the cabinets he found a hammer. Why would he have something like that in here? Oh well, no time for that, questions have to wait.

He smashed the mirror and took the biggest piece. He should probably repay Doofenshmirtz for this one. Oh well, that’s a problem for later.

“Perry the Platypus, sorry for interrupting your private time, but could you please make it quicker? I also would like to step in for a bit… What was that sound? Perry the Platypus is everything okay?”

“Bam!”

And with a powerful kick Agent P bursted open the door making Doofenshmirtz fly over across the room.

Perry ran to the Pillow Heatinator, trying to angle it toward the mirror, but it kept spinning and blasting heat in other directions.

“Gyrururururuk” Agent P said to himself making a sarcastic ‘great’ face.

But Agent P as the amazing agent he is, he found a lever at the side of the -inator.
Couldn’t he spot that 2 minutes ago? Whatever.
He quickly went to the lever and pulled it and the -inator stopped moving.

“No, Perry the Platypus, noooo!”

Agent P then gave it one last shot with the mirror and this time he succeeded, making the Pillow Heatinator overheat.
Just before it exploded, Agent P launched himself into the air using his parachute.

“Curse you Perry the Platypus!”

“Boom!”

“Ouch…”

-Back to Backyard-

“Phineas and Ferb! Oh, hi Baljeet, how are you? Phineas and Ferb!”

“Uhm, hello Candace. The boys are kinda busy right now, is there anything I could do to help you?”

“Yeah, I guess it doesn’t really matter who ends up telling me. Could you please tell me what Phineas and Ferb made today? Which I assume is that one machine that Buford is holding while Ferb is chasing him…?”

“Oh yeah that’s it. It’s a Mood Meter! It’s a machine that allows you to see th-“

“Yeah I don’t care, that’s all I wanted to know. Okay, bye!”

“…Why is everyone so weird today?” Baljeet muttered.

-Back to Candace-

“Mom! Mom! I found out what that crazy machine Phineas and Ferb built is! Now you have to come and see it!

“And what is it exactly?”

“A Mood Meter. Isn’t that creepy? Why would they want to know in what mood someone is?”

“…Honestly, I would use that when you are on your period though… I’m scared even by the thought of talking to you sometimes…”

“What…?? Whatever it doesn’t matter. Come one mom! Quick! Before it disappears again!”

“Okay, okay Candace. A promise is promise.”

Linda followed Candace to the backyard. Whining could be heard from it.
Especially Buford calling Phineas out to something that would absolutely change his life until today. All of a sudden a ray hit the Mood Meter and it started heating.

“Ouch! Hot, hot, hot!” Buford started yelling.

“Huh, Buford what is it? Are you o-“ Phineas said but before he could end his sentence…

“Boom!”

That was the last thing that was heard before Linda stepped outside.

“See mom! I told you there something going one here! I told you! I told you!”

“…Candace, sweetie, what am I supposed to be looking at?”

“Huh? What are you talking about? Can’t you see that weird-shaped-…?”

Candace then turned around.

“Okay, where is it, boys?”

“Whoa, Candace is angry…” Baljeet whispered.

“I- I’m not sure it’s was here just a moment ago but then it just…” Phineas tried to explain.

“Come on, Candace. Let’s leave your brothers and their friends alone, okay?”

“But-but-but-but-but-but…”

The friend group just watched Candace and Linda disappear into the house before Phineas spoke again.

“Okaaaay… that was awkward. So Buford, what did you want to tell me that would ‘change my whole life’?”

“Oh, right! About that, well you see, Isab-“

Ferb quickly clamped a hand over Buford’s mouth and said trying to cover it up
“Oh there you are Perry.”

“Gyrururururuk”

“Perry! There you are buddy.” Phineas grinned and went to pet his platypus.

Buford then turned to Ferb “You do know that someday he will find out about Isabella’s crush on him right?”

“Eh????!!!!” Isabella froze. She heard everything.

“Exactly, Buford. Someday…” Ferb smirked. “Don’t worry Isabella. Your secret is safe with us.”

“…Although it’s not really a secret. Everyone knows. Except for him.” Baljeet added, walking over to the friend group.

Isabella groaned.
“What do you mean everyone?! Oh well…, I guess I could trust you guys with this one.”

“Although, if you do want us to tell him we could-“

“Buford!”

“Okay, okay, sorry for trying to help. Geez…”
