NattyMc is out, PEACE!

Phineas' alarm clock rings 7:00 and a mechanical arm emerges out of it and pokes a sleeping Perry awake, he chatters, waking Phineas and Ferb.

"Good morning, Perry! Now that's the way to wake up" Phineas hugs his pet "This is gonna be the best day ever"

The boys get dressed and ready for the day.

We consider every day a plus

To spend it with a platypus

We're always so ecstatic

'Cause he's semi aquatic

Our Ornithorhynchus anatinus

Brings smiles to the both of us

Life's never fuddie duddy

With our web-footed buddy

When we're brushing our teeth, It's better

Tying our shoes,

{{note}(Oh yeah!)

It's better

Combing our hair, It's better

Like we're a cheese sandwich and he's the cheddar

Blinking our eyes, It's better

Breathing in and out, It's better (So much better)

Sitting in a chair, It's better

And taking a bath is just a little bit wetter

Every day is such a dream

When you start it with a monotreme

He's duck-billed and he's beaver tailed and hairy

(You know that he's hairy)

Everything's better with Perry

(Everything's better with Perry)

Everything's better with Perry

(Everything's better with Perry)

Everything is better with Perry

(Everything is better, everything is better with Perry)

Everything's better and we

Just want to tell you Perry

Everything's better with you (Better with you)

Phineas, Ferb, and Perry slide down the staircase railing and land in a pile on the floor.

Perry chattered.

"Good morning, boys" Lawrence greeted them

"Happy anniversary, Perry" Linda walked in.

"Oh, that's right! Gosh, I can't believe it's been five years. I remember the day we first got you" Phineas said.

(Flashback to 5 years ago, Lawrence and Linda take a younger Phineas, Ferb, and Candace to the "OWCA Animal Rescue Center")

"Come on, kids. Pick out any pet you want" Lawrence said.

"Oh look, Phineas! This one's looking at you!" Linda picked up Phineas and showed him a cat.

"And this one's looking at you, Ferb!" Lawrence picked up Ferb and showed him a dog.

A young Candace walks through the aquarium section and all the fish swim away as she approaches "Why won't anything look at ME?!"

Phineas and Ferb approach a baby Perry.

"Ferb! This one's looking at both of us at the same time!"

Baby Perry chattered

"Awww..." Linda cooed.

"That thing? You're kidding, right?" Candace raised an eyebrow.

A female store employee walked up to them (really Carl in disguise).

"Is there something I can do for you?"

"Ah, yes, we'd like that one, please"

"You want to adopt a platypus?" She asked surprised.

"Oh, is that what it is? Well, yes! May we have him please?"

"What would you even name a platypus?" Candace asked.

"'Course, Ferb and I knew exactly what to call you." Phineas narrated.

"Bartholomew" They said simultaneously.

Baby Perry chattered.

(Present)

"And then when we got you home, we renamed you Perry. And gave you this locket!" Phineas reached into Perry's fur and pulled out a web foot shaped locket on a collar. He opens the locket around Perry's neck, revealing three pictures, one of young Phineas, Ferb, and Perry "Look how young we all were"

Candace is in her room, talking on her cell phone "Hey Jeremy, you wanna go to the mall?"

"You know, I'd love to, but my Dad is taking me to check out his old college today"

Mr. Johnson runs into the room "Boo-ya! Go Polecats! Boo-ya!" Then runs away.

"He's already set up an interview with the academic adviser. Can you believe that?"

"Gee, Jeremy. I forgot you're a whole year older than me. A trip to college? Heh-heh.. That's, that's really great. Okay, well, I'll talk to you later. Bye" She hangs up the phone and picks up a stuffed teddy bear with a picture of Jeremy taped to its face and begins talking to it "Oh, Jeremy! In the blink of an eye, you'll be moving on to the next phase of your life. You'll be going to college and wearing tweed jackets with patches on the elbows! You'll be so mature! And look at ME! I'm a child! Jeremy, you'll see! I can mature! Starting with taking this silly photo off" Candace rips off photo "Oh, Mr. Miggins! Have you been there the whole time?"

The two boys are in the backyard; Ferb places a baseball on Perry's tail.

Phineas holds a baseball bat and taps the home plate "Alright, looks like the pitcher's ready, and...batter up!"

Ferb scratches Perry's neck and Perry's tail snaps forward, flinging the baseball toward Phineas

"Batter batter batter, swing!" Phineas swings at the baseball and hits it "Oh yes, sports fans! That may be the best hit ever in the history of platypult baseball!"

Ferb checks the "Platypult Baseball World Record Book" and gives Phineas a thumbs up.

"And the crowd exhales loudly through their mouths!" Phineas imitates a roaring crowd.

Ferb uses the remote control baseball glove to guide the ball back.

" And Fletcher snags the pop fly! He's out!"

"Hi, Phineas! What'cha doin'?" Isabella enters the backyard.

"Turning Perry's involuntary reflex into a sporting event"

"Hi, Perry! Can I try?" She scratches Perry's neck and the baseball is catapulted out of the yard.

"Whoa, mama! Nice shot, Isabella!"

Baljeet enters along with Buford "Did someone lose a ball?"

"Yeah, we were just playing platypult"

"Oh, I LOVE Platypus-themed sports!"

"You know, if we had TWO Perrys, we could put a net between them and play platypult badminton!" Phineas said.

"Who's Anette?" Buford asks.

"Ferb, that's it! I know what we're gonna do today!"

"No, seriously. Who's Anette?"

They finish up a mechanical platypult.

"Okay, everyone, I think the tail is all set. I'll just go check with the foreman"

Isabella notices Perry's absence "He's gone!"

"Hey, where's Perry?" Phineas checks under the machine "Did he really slip away? On his anniversary? Sometimes it seems like Perry's missed every single cool thing we've done all summer long. Well, I guess he can do whatever he wants. After all, it's HIS day, right?"

Perry is shown hiding behind the tree, his fedora on. He throws a pebble at the fence.

"Hey, what was the small noise?" Baljeet asked.

"Let's all go walk over to it!"

Perry slips into the house while they're gone, he goes to the couch and pulls back a mirror over it, revealing a hole, he goes in and rides a vacuum tube down to his lair, passing by Pinky the Chihuahua and other agents, as he lands at his seat, Major Monogram is on screen.

"Ah, good morning, Agent P. A quick word, recently you've been having some close calls, and your host family has nearly caught you sneaking into your lair several times. No need to remind you, but I'll do it anyway, that if your cover's blown, you'll have to be transferred to another city, with another host family. And we both know you wouldn't like that" He chuckles "I remember the day you were first assigned"

(Flashback to when the Flynn-Fletcher family was just walking out of the adoption agency with their new platypus)

"Enjoy your platypus!"

"Thank you! Cheerio!" Lawrence calls and shuts the door.

The employee takes off her head, revealing it's a mask, under it is a younger Carl with braces on "Agent assignment complete, sir"

"Good job, Carl! If you keep up the great work, you'll make unpaid intern in no time!"

(Present)

"And I did!" Carl says from offscreen.

"Don't get cocky, Carl! Agent P, as you know, every operative is equipped with an auto-scan replication device, just like the one in your hat. We've been using the information you've gathered to replicate each and every one of Dr. Doofenshmirtz's inators. Our top men have been analyzing them to determine if they've been getting smarter or dumber. And, to be honest, the jury's still out. Now we find out that he's in the process of building an alternate dimension-related inator. Your assignment is to stop him, before he finishes building it. Behind you, rising dramatically from the floor, is Carl with some high-tech devices that you might find useful"

A platform rises with dramatic music, on it is a large container of devices.

"Um, Sir? Hello? I didn't step on in time. Would you mind lowering the platform again?"

"Oh, great, let me... cue the music again" He rewinds the dramatic music and plays it again as Carl rises with the platform this time.

"Voilà monsieur!" Carl shows him a wristwatch "This first item is our new wrist-communicationizer. It has many applications that will help you in the field. For example a powerful directional electro-magnet. It will draw any metal object to you" He pushes a button and his glasses are drawn to it "See? And these are aluminum!"

"Quit goofing around, Carl, and show him the hologram"

"Yes, sir" He pushes a button on the watch and turns on a hologram of Major Monogram.

"Hehe, pretty nifty, huh?" He says from the hologram "With this device, you'll be able to contact me anywhere at anytime, but don't call between 3:30 and 4:00, because...that's when I take a shower. Whoa wee, wait a minute" He Points to himslef on the big screen "Is that... me?"

"Oh, no! His holographic projection has become mesmerized by his video image! I better shut it off" Carl shuts off the hologram, then points to the watch again "And if you push THIS button, it'll give your adversary an incredible ice cream headache" He pushes button and immediately screams and holds his head in pain, then stops "Ah! Ah! AH! ..It's gone. You better watch where you point that" Carl hands the watch over to Perry.

Candace, inside her room packages her belongings into a cardboard box.

"Hey, girl" Stacy entered "Uh, what are you doing?"

"Stacy, Jeremy's going to college soon, and here I am concerned with busting my brothers to my MOMMY and living in the NURSERY" She picks up a ceramic unicorn "A unicorn! A UNICORN, Stacy! Hi, I'm six!" Candace says mockingly "You've GOTTA help me get rid of all this junk"

"Wow, bold move!"

"Yep! Good bye, childhood folly. Hello, care-free undemanding adult life!"

Linda walks in "Yeah, good luck with that. Candace, your father and I are off to the movies. While we're gone, you're in charge, okay?"

"Okay, Mom!" She turns to Stacy "And you know, I'm even thinking of giving up on busting my brothers"

"The irony is, that as a grown up, you don't NEED to tell your mom. You can just bust them yourself"

Candace gasped "That's it! Stacy, I'm old enough to bust them myself!"

"That's what I just said"

(***A/N: Changes start at this point!)

Doofenshmirtz Evil Incorporated!

"Now, Perry the Platypus, quake in terror, as I punch a hole through to another dimension! Behold! The Other-Dimension-"

"Sir!" Norm interrupts.

"What? What?"

"I've finished setting up the buffet"

"Oh, for crying out loud, Norm. I was in the zone!"

"I just thought you were playing with your doll"

"It's not a doll, it's a stand-in. Pretendy the Practice-pus, see? I wonder if Perry the Platypus practices with a fake me? It would be nice to know he cares about…" Doofenshmirtz realizes what he's saying and quickly changes to being angry "Where is that stupid platypus? He's late! If he thinks I'm gonna wait up for him, he's got another thing coming!"

The mechanical platypult is finished and Phineas and Ferb are inside the giant shuttlecock.

"All systems are green, prepare to launch on my mark, T-minus thirty and counting. 29, 28, 27, 26..."

(At Perry's lair)

"...Of course, you'll only need this if you're attacked by one of the royals or a member of Parliament, so it's probably okay to leave the safety on. And here's your brand new rocket-car" Carl shows it as Perry gets in and starts it "Sweet huh? Good luck, Agent P!"

Perry starts the car.

"Uh, Carl, did you tell him the accelerator's a little touchy?"

The rocket car roars off, going right through the ceiling.

"I think he knows, sir"

(At the backyard)

Phineas is still counting down "...3, 2, 1, service!"

Isabella pushes a button marked INVOLUNTARY REFLEX, and the platypult launches them, at the same time, Perry's rocket car bursts out of the ground nearby and collides with it, sending them both careening away from each other.

Candace and Stacy run into the backyard.

"Phineas and Ferb, you are so bus... Oh my gosh! Where'd it go? You there! Small children! Where's the big contraption?"

"I don't know, it was here just a moment ago" Isabella shrugged.

"It disappeared! Stacy, do you realize what this means?"

"We're done?"

"No, some mysterious force always takes away Phineas and Ferb's inventions before Mom shows up, this time, it took it away before I showed up! The mysterious force recognizes that I'm now a grown-up!"

"Mysterious Force? I'm not buying it, I am a woman of science, at least that's what my horoscope said…" She trails off.

"Well I'm going to prove it to you and bust my brothers at the same time, Where are my brothers?"

"We just launched them toward the park, Buford is there with the other platypult" Baljeet answered.

"Okay children, as the adult here, I say we're going to the park, does anyone have to go potty first?"

Stacy raises her hand.

"Fine, make it quick"

(In the air)

"Wow Ferb, we're coming in a little too fast. Do you think you can slow us down?"

Ferb shook his head no.

"Oh…well ok" Phineas shrugged as their shuttlecock got closer to the park.

Meanwhile, Perry is on the ground, his smoking rocket car is being picked up by a tow truck.

"You're lucky I got a rocket car winch, lots of guys don't have that" The driver said.

Candace, Stacy, Isabella, and Baljeet walk up to Buford, who is on a park bench, chewing some gum.

"Okay Buford, where are Phineas and Ferb?"

"They should be here right…about…now" The shuttlecock with Phineas and Ferb in it landed on the net of the platypult and winded back.

"Hi Candace" Phineas waved before the platypult catapulted them back up into the sky.

"You guys are SO busted!" Candace called after them.

"Well, that's all I had planned for today" Buford got up from the bench "I'm gonna chew some victory gum"

Victory Gum!

"A tradition as old as the game itself" Buford chewed.

"Don't play with me, young man, where is that shuttlecock taking them?"

"Back to your house, where the OTHER platypult is"

"Oh really? Did you hear that, Stace? The mysterious force took my brothers away before I, the grown up, could bust them!"

"Yeah yeah, I'm sure there's a logical explanation for all of this"

The tow truck driver from before is towing the Platypult from their backyard.

"And they laughed at me for installing a platypult tow rig. Who's laughing now, Wayne?"

(Back to the park)

"The logical explanation IS the mysterious force, the question is, why does it care so much about my little brothers? Why doesn't it want them to get busted?"

"Well, why don't you ask it, Kierkegaard?"

They stared at him.

"What? Existentialist Trading Cards" He holds up the cards "Came with the gum"

"Wait, he's right! I should just ask it, I'll bet I can reason with it"

"Reason with it? Candace, it's a force; that you made up"

Candace starts to sing.

Let me explain, though it might seem strange to you

So please refrain from thinkin' bad of me

It gives me pain when I see what my brothers do

But no one else ever can see

I just want the truth known, so I call mom on the phone

But by the time she gets here, the whole thing disappears

Whatever they build every day, it gets taken away

No one sees it, of course, it's some mysterious force

To my mother every story's preposterous

Never believes no matter what I do

But though I'm right and she's wrong, I must confess

I'd probably think I'm crazy, too

I just want the truth known, so I call mom on the phone

But by the time she gets here, the whole thing disappears

Whatever they build every day, it gets taken away

By some mysterious force, no one sees it, of course

Some mysterious force

Some mysterious force

Some mysterious force

Some mysterious force.

"Now do you understand?" Candace asks her.

"Well actually I-"

"Good! Come on Stacy!" Candace pulled her.

"Where are we going?"

"To my backyard, the heart of the mysterious force! We are going to bust my brothers!"

The kids shrugged and followed them.

(In the Backyard)

Phineas and Ferb land in the backyard and get out of their shuttlecock.

"Hey, where'd the other platypult go?"

Ferb shrugged.

"Aha!" Candace burst into the backyard "You guys are so Busted- where'd the platypult go?"

"I don't know"

"Well it doesn't matter because the shuttlecock is still here- hey where'd it go?" Candace looked around.

"It was here a second ago" Phineas shrugged.

The tow truck driver laughed down the street, his truck towing the giant shuttle cock.

"Take that Wayne!"

(Back in the Backyard)

"B-b-b-b-but! It was here! I couldn't have failed! I'm a grown up!"

"I guess the mysterious force strikes again" Stacy shrugged.

Candace got down on her knees and gave a cry to the world "CURSE YOU MYSTERIOUS FORCE!"

Just then Linda and Lawrence walked into the backyard.

"Hey kids, the movie got cancelled so we had to come home; who wants some pie?"

"I do!" Everyone screamed and ran into the kitchen except Candace.

"Candace honey, don't you want some pie?"

"Yes, yes I do! I am done being a grown up! I give up!" She stomped into the kitchen.

"That's nice dear"

(At DEI)

Perry kicked down the door.

"Finally!" Doofenshmirtz got up from his chair "It took you long enough to get here! Do you know how long I was waiting for you to show up? No matter! Welcome to your trap!"

He clicked a button and a cage fell over the mammal.

"Now! Behold! My Other Dimensionator! With it I can travel to different Dimensions and possibly take them over! Or I can just have people pay admission to enter and then I'll be rich! Whichever comes first!" Doofenshmirtz got ready to press the button but was kicked in the face.

The scientist sat up and looked at the platypus and the now empty cage.

"How did you escape?"

"I LET HIM OUT, SIR" Norm smiled.

"Why on earth would you do that, Norm?"

"HE GAVE ME 5 DOLLARS"

"No matter! You'll never stop me!" The scientist kicked the platypus to the far wall by the couch and ran to the machine, his finger hovering over the button "By the time you get all the way back over here I will have activated the machine already! There's nothing you can-" Doofenshmirtz sniffed the air and his eyes widened "Did you just pee on my couch?"

The platypus hopped off the couch revealing a stain.

"You did! Perry the Platypus that's disgusting! What is WRONG with you?!"

While the doctor was distracted, Perry lunged at him and pushed him away from the machine. When Doofenshmirtz tried to reach out and push the button, he was bitten.

"OW! Did you just bite me? That hurt! You are just MEAN today!"

The platypus rolled his eyes, and he was immediately grabbed by Norm.

The scientist got up and brushed himself off "You can't just go around biting people and peeing on their couches Perry the Platypus! Really! It's not even evil, just downright rude!" Doof walked over to the machine "And now! The mind blowing first images from beyond our dimensional reality!"

He pushed the button and a portal started to form dramatically. Both their eyes widened as it formed, and then a room with a couch in shades of pink and purple appeared.

Doofenshmirtz stared dumbfounded.

"Huh, it's a...it's a couch"
