In this chapter, Phineas and Ferb are going to become official KND agents. Whoopee! Meanwhile, Perry the Platypus is going to be sent on a mission to battle Dr. Doofenshmirtz...but he is not alone this time...

Chapter 4: Welcome To The KND

After their training session at the Arctic Base which had ended up with them assisting the KND agents in defeating a group of evil ice cream men, Phineas and Ferb were ready to return to the Moon Base along with their friends.

Though admittedly they had wandered off on their own in the middle of the fight, Numbuh 60 was willing to cut them a slack. They made holding off the evil ice cream men a LOT easier.

Whether they were there to take the KND Code Module or simply conquer the arctic base they weren't sure. Either way, the KND were glad that that Arctic Base and the KND Code Module were both safe.

"So...have they completed their training?" asked Numbuh 362. Though she was patient, the same could not be said for Numbuh 86. She wanted her to hurry up and make the five children become Kids Next Door operatives already so that she could go home to her father.

Incidentally, her father was Mr. Boss, one of the KND's greatest enemies. It was rather ironic...even if Mr. Boss wasn't quite as big of a threat as Father was to the Kids Next Door.

"Yes...they even helped us defeat the evil ice cream men..." answered Numbuh 60. Perhaps they should try that tactic again in the future in case more of the ice cream men showed up. It was rather creative of them to think about destroying their ammunition so that they couldn't fight back.

They seemed to have a particular habit of attacking the Arctic Base. Maybe they didn't attack the Moon Base because nobody could eat ice cream in space? Or was it because nobody could hear them scream like little girls?

Then again, Stickybeard had attacked the Moon Base once even though his vessels were typically water-based. Did they even have an underwater treehouse? If so, they might need to defend it from him.

"Well then, I think you're ready to become KND operatives. Put your DNA in the code module for us, will you?" asked Numbuh 362. The other KND operatives were waiting.

Phineas nodded. They would want the KND Code Module to recognize them as official KND operatives. Chances are the Moon Base might have scanners to prevent unauthorized entry.

Phineas plucked out a hair on his head, Ferb pulled out a stick of gum from his mouth, Isabella drooled on the KND Code Module, Buford plucked out an armpit hair...and Baljeet pulled out...a leg sock?

Well, it did the trick. Phineas and Ferb were registered in the KND along with their friends.

Now they could help protect the world from evil adults...though personally they did not know any evil adults...other than the Smile Away Reformatory Sergeant, that is. He once tried to destroy their imagination...it was rather heinous.

"Congratulations! Welcome to the KND! I hope that you plan on serving us in the future...just keep in mind that once you reach thirteen you'll be decommissioned, alright?" asked Numbuh 362.

"Decommisioned?" inquired Phineas.

"It's standard procedure...unfortunately, some kids have the tendency to turn to the dark side once they become teenagers...such as Cree and Chad for instance." answered the leader of the KND. It was rather unfortunate that they would eventually decide to rebel against the KND considering how effective they were back when they were still members of the KND.

"I guess we're not going to be part of the KND forever, Ferb...we'll just have to enjoy it while it lasts. Still, at least we'll get to be part of the KND longer than we'll get to enjoy our summer vacation..." noted the boy. They weren't sure what exactly they were going to do on the last day of summer. Hopefully it would be something truly exciting.

"Don't worry, you won't grow up for quite some time, I can assure you. I've been the Supreme Leader of the KND for quite some time myself...though admittedly I did seek to retire once..." answered Numbuh 362. Sometimes the pressure of the job got to her...though she usually managed to put up with it. She must be made of iron.

Speaking of that incident, that had been quite a day...oddly enough, she didn't think broccoli tasted so bad...though she still had to go to the KND hospital because she had a stomachache. It was a good thing they had a section dedicated to food poisoning.

"For now, we're going to get you a treehouse..." stated the Supreme Leader.

Immediately, she handed Phineas and Ferb a seed.

"You can use this to plant your own treehouse...just make sure to plant it OUTSIDE your house instead of inside it...that could cause a lot of problems..." answered Numbuh 362. Some of the rookie KND operatives had made that mistake and the KND construction team had to sort it out. Not fun for anyone.

Phineas and Ferb nodded. Fortunately, they knew just the place for it.

A few minutes later...

"Ready, Ferb?" asked Phineas.

Ferb nodded.

Immediately, Phineas planted the treehouse on his lawn.

A few seconds later, it grew to a massive tree.

"Whoa! That was fast!" bellowed the boy.

"It certainly was." nodded Ferb. The Kids Next Door certainly were smarter than their young age would suggest.

Now all they needed to do was set up some defenses to keep the treehouse safe from intruders. They wouldn't want any adults breaking in...they in fact had heard about the incident where a Teen Ninja had chopped down a treehouse and taken down all the KND agents.

They didn't want that to happen to them, to say the very least.

Little did they know that the perpetrator was someone that they knew...

Fortunately for Phineas and Ferb, they were able to weaponize the treehouse rather quickly. They even included a cloaking system to hide the treehouse from intruders.

Sure enough, one of the adults noticed their treehouse...and assumed that they were simply hallucinating once it disappeared.

"This sure is a nifty treehouse..." answered Baljeet.

"We're probably going to be spending a lot of time in here..." stated Isabella. After all, they were now official KND agents.

"I'm looking forward to being a KND agent!" exclaimed Buford. Now he could get to fight evil adults...like the one that wouldn't let him wedgie a kid.

Oh wait, most adults would probably object to that...

Oddly enough he had met an evil adult once...but he had decided that he would rather be with Baljeet. They were best of friends...or should they say enemies?

"I wonder when we'll receive our first mission..." stated Phineas.

For now, it appeared that they were on standby.

When they needed to stop an evil adult, they would no doubt receive orders from the Moon Base.

Until then, why not try building something fun? Maybe they could find a way to use it to fight the evil adults that the Kids Next Door claimed were abundant.

Meanwhile...

"So, this is the Delightful Manor? It's huge!" bellowed Dr. Doofenshmirtz. No wonder Father was so popular among the other villains. Not even Doofenshmirtz Evil Incorporated was as big as the Delightful Manor as it was.

Speaking of which, it also appeared to have its own defense systems. Perhaps Dr. Doofenshmirtz should design some to keep Perry the Platypus out. He was getting tired of him breaking into his skyscraper.

Personally, he wished that he had an evil lair like that. Perhaps he could design one some day.

However, as soon as he entered the Delightful Manor, he noticed that there was a long line...much to his chagrin.

Well, he might as well enter the line and wait for everyone to sign in.

After what felt like forever, he got his chance.

"Finally! I was worried that I was going to have to pack my bags and go back home!" exclaimed Dr. Doofenshmirtz.

Sure enough, there was Father, sitting on a desk.

"So, you wish to join the battle against the Kids Next Door...why don't you take a seat..." stated the man.

Dr. Doofenshmirtz sat down. At this point his legs were killing him...more than Perry the Platypus.

"So...what do you have to offer?" inquired Father. Surely he came to the Delightful Manor because he had some sort of talent...preferably a talent at being evil like he was.

"Well, I'm pretty good at inventing things!" exclaimed Dr. Doofenshmirtz.

"So are my children actually..." answered the evil man. How many inventions had they made, anyway?

Currently, they were building a device that they could use against Nigel Uno. It would be so much to completely humiliate him.

"Huh. I wish my daughter Vanessa was like that..." stated the mad scientist.

"What have you built previously?" asked Father.

"I once built a machine that could turn youngsters into adults..." stated the man. Of course, he was going to use that for cheese making...but Perry the Platypus forced him to use it in anger.

"Very interesting..." answered the man. "I would love to see more of your inventions..."

"That's kind of a problem..." said Dr. Doofenshmirtz.

"How so?" inquired Father.

"Every time I build something, Perry the Platypus destroys it..." explained the evil scientist. He had lost count on how many times perry the Platypus had shown up and foiled his evil plan. And to think that he came up with one every day of the summer.

Eventually, he was going to start running out of ideas.

Father was rather curious to discover just who Dr. Doofenshmirtz's nemesis was.

"A platypus?" asked the man.

"Yeah...he's more than a platypus, really. He's a semi-aquatic mammal of action!" exclaimed Dr. Doofenshmirtz.

"I was under the impression that your nemesis would be a kid..." stated the confused Father.

"Well, he's about the age of a kid..." answered the man. Not in platypus years though.

"Although, the fact that you claim that your nemesis is a platypus gives me an idea...how would you like someone that will help you dispose of that particular animal?" asked Father.

"That would be very helpful!" exclaimed Dr. Doofenshmirtz.

"Alright then...I happen to know someone that often uses platypuses in her recipes..." stated the man.

"Really? Why haven't I heard of her?" asked the mad scientist.

"Believe me, a lot of people don't like her cooking...especially children..." noted Father. Nonetheless, they kept her around because she was typically very effective at fighting kids, especially the Kids Next Door. She could take out an entire squad of KND agents.

Immediately, Father rang a bell.

"Grandma Stuffum! We've got a request for you!" exclaimed the man.

At that very moment, an elderly lady wearing glasses and wielding a spoon showed up.

"Yes? Are there children that need fattening?" asked Grandma Stuffum.

Dr. Doofenshmirtz remembered trying to make the people in the Tri-State Area once, oddly enough. But in the end HE was the one that ended up becoming fat.

And yes, sometimes Dr. Doofenshmirtz fell victim to his own schemes, like the time where he tried weaponizing an aging device against Perry the Platypus. To his credit, he wasn't originally planning to do that...he simply wanted to make cheese.

But unfortunately, Perry the Platypus turned out to be rather gluttonous. He ate all the stinky cheese before he could have some. So much for him trying to give up a life of evil.

"Actually, we need you to take down a particular platypus...whoever he is..." answered Father. Oddly enough, he did try to turn KND operatives into animals once. He ended up becoming an animal himself.

"Oh...well, I do enjoy having platypuses in my recipes!" exclaimed the evil grandmother. Perhaps she would serve that platypus in a recipe for children later. There were so many skinny children in the world...except for Numbuh 2. Why was she trying to feed him in the first place? It would probably be better if he exercised rather than ate lunch.

Of course, the KND weren't particularly fond of sadistic gym teachers either. Typically they dealt with them after gym class after they were tormented. Fortunately, not all the teachers in the school were sadistic and therefore had to be battled by the KND.

"You do?" asked Dr. Doofenshmirtz. Though admittedly he did enjoy trapping Perry the Platypus, the thought of eating him actually hadn't occurred to him.

Whatever meant that he could conquer the Tri-State Area without opposition, he supposed. Personally he wondered what Perry the Platypus would taste like.

Since he was a semi-aquatic mammal of action, maybe it would be a bit like drinking coffee.

"Why is your nemesis a platypus, anyway? They don't do much..." answered Father. He was under the impression that it would be a particularly obnoxious kid that wouldn't leave him around.

Of course, it was possible that that particular platypus happened to belong to somebody. Maybe it was a zookeeper?

"That's what they all say..." stated Dr. Doofenshmirtz. They wouldn't think so if they ever saw Perry the Platypus in action. He DID do much, including save the Tri-State Area.

To make a long story short, he was the reason Phineas and Ferb were living such a good life. Without him, they probably would be living in a world without summer.

"By the way, I love your children! I'm so glad that they build inventions just like me! I wish my daughter was that evil..." stated the doctor.

"Well, to be honest, they're not really my children..." answered Father. He in fact had abducted Kids Next Door agents and delightfulized them...incidentally, it made his comrades want to throw up when he explained it to them, though it didn't make them leave his side.

"If they're not your kids, then why do they call you Father?" asked Dr. Doofenshmirtz.

"I don't usually go by my real name..." stated the man. It reminded him of his father...whom he hated due to the fact that he was a jerk and preferred his elder brother over him.

Of course, he did decide to recommission him not out of love but due to the fact that he was incapable of defeating the Kids Next Door by himself. That was why he had decided to tell him to get lost.

Dr. Doofenshmirtz nodded. Perhaps that was why he decided to refer to himself as a doctor rather than Heinz Doofenshmirtz. It did sound more evil that way.

"Well, now that you're a member of the adults that are fighting against the obnoxious Kids Next Door, I suppose you can go home now..." answered Father.

Dr. Doofenshmirtz smiled. He couldn't wait to start his next scheme to conquer the Tri-State Area now that he actually had allies on his side. They would no doubt come in handy.

Still, they seemed to despise children instead of platypuses. Maybe they would help him with the Fireside Girls. Alternatively, he could simply put on a Do Not Disturb sign.

Personally he wondered what naughty thing he should do today to attract the OWCA's attention. There were a lot of possibilities.

Perhaps looking outside would give him ideas.

Suddenly, he had an idea. Someone had accidentally tipped over a trash can.

What if he littered the Tri-State Area and covered it with garbage? Surely that would get Perry the Platypus to show up...and then he could trap him.

Of course, he had already trapped him many times before.

This time he was going to build the Garbageinator.

He was looking forward to it. No doubt that it would take people a long time to clean all the garbage up.

Quickly, he began to purchase supplies for his latest invention.

Unsurprisingly, he immediately attracted Major Monogram's attention. He always knew whenever Dr. Doofenshmirtz was plotting something evil, as he and the other OWCA agents had a habit of monitoring him and the other evil scientists in the world.

He proceeded to inform Perry the Platypus to head to his lair to receive orders.

Incidentally, Perry had secretly been trained since birth to be an agent of the OWCA.

Why were the OWCA agents all animals with rare exception you may ask? So that nobody would suspect them of being secret agents...at least, not while they weren't wearing their fedoras.

For some strange reason people couldn't recognize them without their fedoras. At least, not Dr. Doofenshmirtz anyway.

As soon as Perry received a message from Major Monogram, he decided to use one of the many different secret entrances in the treehouse.

Personally, he wondered what Dr. Doofenshmirtz was up to this time. He always built a different device to take over the Tri-State Area. They certainly were a varied bunch.

He in particular had been zapped by many different inators at once...though in that particular case he ultimately ended up experiencing the Go-Homeinator...which took Perry the Platypus back home.

Personally Perry wondered why he would build such a thing if he was already at home...

Anyways, it was time to begin the mission.

A middle-aged man appeared onscreen.

"Good morning Agent P. The evil Dr. Doofenshmirtz is up to no good again. This time he appears to be gathering things from the garbage dump..." answered Major Monogram.

"You think that's where his destroyed inventions end up, sir?" asked Carl, Major Monogram's bespectacled assistant.

"Most likely..." stated the man.

"You need to go out there and put a stop to it, Agent P!" exclaimed Major Monogram.

Perry the Platypus nodded. Saluting Major Monogram with respect, he set out to stop Dr. Doofenshmirtz.

I hope that you like this chapter...in the next chapter, Phineas and Ferb are going to face off against a vampire...you probably know which one. And no, it's not Candace. Heh heh heh. I know that there was one episode where Candace believed that she was a vampire.
