Phineas and Quite Possibly Ferb

It looks like we're doing a Phineas and Ferb fanfic this time…since Kim Possible is basically Phineas and Ferb's predecessor…it seemed like a decent idea.

I wonder how long Phineas and Ferb is going to be on the air anyway…it's already outlasted Kim Possible.

Not like I think that's a bad thing mind you…I'm actually rather happy that Kim Possible had a fourth season…I don't mind that they've decided to end the series though…it was rather good while it lasted.

Right then…let's start this fanfic, shall we?

Chapter 1: Moving In To Middleton

Inside their parents' car, two kids were awaiting their new home.

These two kids happened to be Phineas and Ferb.

"Gee…Ferb , it feels awfully strange moving to in a new place so suddenly…" noted Phineas.

Ferb nodded.

As it turned out, their father had gotten a new job at Middleton…so they had decided to move there.

Fortunately, Middleton wasn't too far from Danville…so they didn't have to worry about not being able to visit their friends.

Still, they were starting to feel a bit homesick.

After about an hour or two of driving, they stopped at their new home.

Oddly enough, it somewhat resembled their old one…though there were a few differences here and there.

On the plus side, Phineas and Ferb would get to explore their surroundings.

Incidentally, summer vacation had just ended for them…so they were going to have to go back to school.

Fortunately, their parents had already signed them up for Middleton Elementary School.

They had heard that a famous celebrity happened to live there…maybe they should ask for their autograph?

They weren't quite sure who it was yet, though.

"Well, we're finally here." said Phineas and Ferb's father, Lawrence Fletcher.

Phineas and Ferb immediately unpacked their bags and stepped into their new home.

They had to admit…though they missed their old home, they thought they were going to enjoy their new house.

Not only that…but they should still be able to continue building their inventions and whatnot.

"Well, maybe moving won't be so bad. I wonder how Candace is doing though." noted Phineas

"She seems rather…upset." acknowledged Ferb.

Sure enough, Candace appeared to be in her room, crying.

"Maybe we should try to comfort her?" asked Phineas.

Ferb nodded.

Immediately, they decided to make a Ducky Momo figurine for her.

"Hmm?" inquired Candace.

Sure enough, this seemed to do the trick…though Candace still seemed a bit lonely.

"Don't worry, Candace. You'll still be able to see your boyfriend, Jeremy." stated Phineas.

"Really? I will?" asked Candace.

"You just have to drive back to Danville…that's all." explained the young boy.

Immediately, Candace began to cheer.

"Well, it looks like we've solved that problem." noted Phineas.

Afterwards, they went downstairs to where their mother was.

"Remember…you're going to Middleton Elementary School tomorrow." explained Linda Fletcher, also known as Lindana back when she was younger.

Phineas and Ferb nodded. Personally they wondered what their new school would be like.

Hopefully the classes would be rather interesting.

Speaking of which, they began to wonder where their pet platypus was.

"Hey, where's Perry?" inquired Phineas.

Hopefully the movers didn't forget him. They didn't want him to be left alone. How would he survive?

Deep below Phineas and Ferb's house…

"Good morning, Agent P." stated Major Monogram, Perry the Platypus's boss.

As it turned out, Phineas and Ferb's platypus just so happened to be a secret agent.

Why was a platypus a secret agent, you ask? Well, the OWCA (aka the Organization Without A Cool Acronym…unfortunately) decided that since a platypus normally didn't do much…nobody would suspect one to be a secret agent.

Well that, and Major Monogram happened to really love animals. Prior to working with the OWCA, he happened to be a zoologist.

After a mad scientist made off with his wallet, he had decided he should build a top secret organization to foil their plans of world domination using animals throughout the world. He figured they would be the ideal soldiers.

So far, the organization had been rather successful.

"Grugggg…" murmured Perry the Platypus.

"What's that? You want to know why we moved you from Danville to Middleton? Well, the evil Dr. Doofenshmirtz just happened to have relocated his headquarters there…he felt that it would be an ideal place to concoct his evil schemes…we believe that he wishes to conquer Middleton and change its name to…well, Doofenton." explained Major Monogram.

Perry raised an eyebrow.

"Fortunately, he does not appear to be concocting any evil schemes at this time…as usual, we'll let you know if we believe that he is up to something." stated the man.

Perry nodded his head.

After giving his boss a salute (as he typically did whenever Major Monogram entrusted him with a mission), Perry the Platypus left the lair.

He then returned to his new home, where Phineas and Ferb were waiting.

"Oh there you are, Perry!" exclaimed the boy. Fortunately, Perry always returned to the Fletchers before too long.

It would be a pity if he were to ever suddenly go missing for an extended period of time, after all.

Shrugging, the duo decided to head back to their room, as they needed to go to bed. It was getting rather late, to say the very least.

The next day…

After going to elementary school (and getting As in each of their classes), Phineas and Ferb went back to their rooms to relax.

They were rather happy that their day at school had gone well, to say the very least. Sure, Buford had bullied them once or twice…but they hardly remembered it.

Suddenly, their mother began to knock on the door.

"Hey there! Just wanted to let you know that your father and I are going to be out of the house for a few hours…so we're hiring a babysitter!" exclaimed Linda.

"Doesn't Candace usually babysit us?" questioned Phineas.

"She's on a date with Jeremy." she explained.

"Ah…" nodded the boy.

Curious, he began to wonder who the babysitter was.

"Can I ask you who the babysitter is?" asked Phineas.

"Her name is Kim Possible. She happens to be a cheerleader at Middleton High." explained Linda.

At that very moment, they began to hear knocking coming from outside.

"I guess that's her now." noted Phineas's mother.

Immediately, she went to answer the door.

Sure enough, it was Kim Possible in the flesh, a legendary crime fighter who has saved the world more times than you could count on one hand…unless you happened to be a mutant.

Of course, when she wasn't trying to save the world…chances are that she was trying out for cheerleading practice…or she was babysitting somebody for cash.

Since she saved the world for free, she had to find a way to make money somehow.

"Greetings!" exclaimed Kim.

"You're the babysitter I hired, right?" asked Linda.

Kim Possible nodded.

"Good…make sure my boys don't hurt themselves…alright?" inquired the lady.

Kim Possible nodded once again.

Immediately, Linda and Lawrence left in their car. Personally they were looking forward to doing some sightseeing.

Middleton was going to take some time getting used to…so they might as well get started.

Being polite as usual, Phineas shook Kim Possible's hand.

"I'm pleased to meet you." said Phineas.

"It's nice meeting you two." answered Kim Possible.

"I heard that you have your own website…" noted the boy.

"It's true, I do…I think that's how your parents managed to find me." acknowledged the cheerleader..

"You can do anything, right?" inquired Phineas.

"Well, maybe that's an exaggeration…but I certainly can babysit!" exclaimed Kim. Maybe she could go by a more modest theme motto. She didn't want people to think that she was arrogant.

"Personally I always thought that Ferb could do anything…" noted the boy.

Ferb began to blush.

'"Is that your brother?" inquired Kim.

"Well technically, he's my stepbrother. I always consider him to be my brother though." answered Phineas.

"How sweet." stated the babysitter.

Phineas had to admit, he and Ferb were rather…close.

"I suppose you can run off now and do something fun…so long as you let me keep an eye on you…" said Kim Possible.

Phineas and Ferb both nodded.

Outside the house…

Nearby, Ron Stoppable was wondering where his girlfriend (who of course was Kim Possible) was. She had left her Kimmunicator at home and Wade (the boy who supplied her with missions) had a mission for her. Dr. Drakken was up to no good again…as usual.

She had heard that she had decided to babysit two of the newest citizens of Middleton…and wondered if this was where he could find her.

"KP! Where are you?" inquired Ron Stoppable.

Hopefully, Dr. Drakken would wait for her to show up before he began his latest scheme…

…then again, probably not.

Suddenly, they noticed that there was a platypus in the backyard.

"That's an interesting pet they have…" thought Ron.

Rufus (his pet naked mole rat) nodded.

Suddenly, they noticed that the platypus had mysteriously disappeared.

"Where did he go?" inquired Ron Stoppable.

As it turned out, Perry the Platypus was going on another mission.

"Good morning Agent P. The evil Dr. Doofenshmirtz has been purchasing satellite equipment as of late…we believe that he's plotting something evil…" explained Major Monogram.

Perry was not surprised. Every day of the summer, Dr. Doofenshmirtz would always come up with something rather heinous.

In fact, he seemed to come up with something evil every day of the year. Yesterday just so happened to be the exception.

However, at that very moment, Carl (AKA Major Monogram's assistant) decided to pay them a visit.

He was currently eating a delicious taco from Bueno Nacho, Ron Stoppable's favorite restaurant in the world.

Immediately, Rufus picked up the smell.

"Delicious!" exclaimed the naked mole rat.

And yes, Rufus was capable of speech…though it was rather limited.

Looking for food, he went underneath a hole in the fence.

Ron Stoppable was not amused.

"Hey, little buddy! You can't go through there! That's trespassing!" bellowed Ron.

Suddenly, Rufus disappeared using the secret passageway that Perry had used.

"Rufus? Where'd you go?" asked Ron Stoppable.

He sure hoped that Dr. Drakken didn't abduct him or something. Completing missions was so much harder without him.

"This is one good taco…" remarked Carl.

Suddenly, Rufus dropped through a nearby pipe.

"What the-" exclaimed the teenage boy.

Curious, Rufus began to wonder where he was.

"Er…you wouldn't happen to be a member of the OWCA, would you?" inquired Carl.

"Huh?" asked Rufus.

Perry the Platypus raised an eyebrow. Throughout his long career as a member of the OWCA…he had never noticed a secret agent like him.

Then again, the OWCA did seem to have a lot of recruits these days…they had one for each letter of the alphabet in fact.

Naturally, he represented the letter P…and he wished that some people would keep their jokes to themselves.

Wait…did he just talk?

"Sir, I think we might have a security breach!" bellowed Carl.

Major Monogram raised an eyebrow.

"Really? It's not unusual for animals to pay me a visit…just last week I was visited by Agent F…" stated Perry's superior officer.

"You mean the flamingo?" inquired Carl.

"Yes…Fifi the Flamingo." answered Major Monogram.

Curious, Perry began to wonder why each of the agents' names started with the same letter as the animal species.

Was it all just some sort of bizarre coincidence?

He couldn't help but shake the feeling that even this mysterious new animal that had entered his secret agent hideout had a name that matched that of his species…as in a sense he was a rat.

"I just don't remember him being an agent of ours…" stated Carl.

Curious, Major Monogram began to search through their records.

Sure enough, Rufus was not an OWCA agent.

"Well, since he's an animal…I suppose we might not need to use the Amnesianator…since he can't spill the beans on our organization." noted the man.

"But he can talk!" exclaimed Carl.

"He can talk?" inquired Major Monogram. Even among the animal agents that was rather new…with the exception of Agent Polly.

"Hi!" bellowed Rufus;

"Great googly moogly!" bellowed Major Monogram.

"Googly…moogly?" inquired Rufus.

That was a rather interesting catchphrase. Then again, he heard Kim Possible and his owner say "What's the sitch?" and "Booyah!" quite a bit.

Suddenly, Carl remembered something from the past.

"You know…I once did a few experiments on naked mole rats…I wanted to see if I can make them secret agents." explained the teenager.

"You did?" inquired Major Monogram.

Perry the Platypus raised an eyebrow.

"I wanted to see if I could make them resist sunlight and give them the intelligence of a human…" stated Carl.

"How did that turn out?" inquired Major Monogram.

"Not too good. Almost all of the naked mole rats were completely unaffected…except for the fact they developed a craving for cheese." explained the teenage boy.

"Did they now?" asked the man.

Rufus raised an eyebrow. That sounded rather…familiar.

"Grugggg…" murmured Perry the Platypus. This was getting rather interesting.

"There was however one exception. He turned out to be a promising success. I sent him to Smarty Mart since it was standard agent procedure…" explained Carl.

Rufus gasped in surprise. That sounded like him exactly.

"Smarty…Mart?" inquired the naked mole rat.

"Now that I think of it…maybe that naked mole rat was you. Small world, isn't it?" inquired Carl.

Rufus nodded. Apparently, the experiment was quite a success with him…considering the fact that he could now talk.

Now that he thought of it…he had always wondered why sunlight didn't faze him like the rest of his race…and why he was the only one that could talk.

He was a bit of an anomaly among his species.

"Sandwich?" inquired Rufus.

"Huh? You want a bite of this sandwich?" asked Carl.

Immediately, he handed a piece of the sandwich to Rufus, much to his delight.

"Well, since the Amnesianator requires a lot of electricity…would you be interested in becoming a secret agent? You do happen to be an animal…that happens to behave much like a human." noted Major Monogram.

"Sure…" nodded Rufus.

Immediately, Carl handed Rufus a fedora so that everyone would know that he was a secret agent…with the exception of the majority of his friends and family.

Of course, the OWCA had a policy regarding not having an agent's cover blown. Dr. Doofenshmirtz had found that out the hard way.

Carl beckoned Rufus to their training center…where he was subject to such training as karate chopping a dummy, running on a treadmill…and for some strange reason, reciting the alphabet.

He passed all three tests with flying colors.

As such, Carl decided to name him Agent R…after his first name and the last part of his species name.

However, since he was still a newcomer, he was going to be assigned to Perry the Platypus to help show him the ropes.

Normally, they would only assign one agent to one evil scientist…but times like this were the exception.

Of course, he and Perry were going to be battling Dr. Doofenshmirtz…

Immediately, they sped off on the latter's hover car.

Hopefully they would be able to save the day before anything terrible happened…like the time Dr. Doofenshmirtz nearly dropped a water balloon on Tokyo.

It would have been one heck of a surfing party.

I hope you enjoyed the first chapter…because if not, I might want to discontinue the fanfic…

And yes…I decided to explain why Rufus can talk and withstand sunlight…this is a Kim Possible and Phineas and Ferb crossover fanfic, after all.

In the next chapter, Perry the Platypus and Rufus the Naked Mole Rat are going to try to stop Dr. Doofenshmirtz…but he's not going to be alone.
