Meanwhile, several miles from Middleton, the car carrying Phineas, Ferb and their family was on the road.
"Okay you two, listen up!" Candace said "I'm getting the chance to hang out with Kim Possible, who I recently learned is famous all around the world. So if I become her friend, I'll be famous too. So there is no way you two are going to ruin this for me, understand?!"
"I really wish we didn't have to leave Perry behind" Phineas said, ignoring his sister.
"I am sorry about that, but I just don't think he'd do well on this trip" Lawrence explained from the driver's seat.
"Anyway, I'm sure Isabella will take good care of him" Linda added.
"I guess" Phineas said "and how much trouble can he get into?"
"You and I are going to have so much fun Perry, yes we are" Isabella said, as she held the platypus in her arms "and when Phineas sees what a good job I've done of watching you, he'll be very impressed."
Isabella sat the platypus on the floor next to Pinky "you stay there, and I'll go get you some food, okay?" she said.
After she left, Perry checked to make sure no one was watching, then pulled out his fedora. Climbing up a curtain, he jimmied open the window and headed towards his owners' house.
"Here you are Perry, fresh from the…Perry?" Isabella said, surprised that Perry was no longer there "hey, where's Perry?"
As it turns out, Perry had made his way to his Chimnevator and arrived at his secret base. As usual, Major Monogram was there to greet him.
"Ah, glad to see you've arrived Agent P. Our sources tell us that Doofenshmirtz's lair is being fumigated and he's left town. We did some tracking and traced him to this location" Monogram said, as a map appeared on the screen "track him down and see what he's planning."
"See if he'll pick up some milk on the way" Karl added from offscreen.
"I told you, do your own shopping!" Monogram replied.
Perry saluted his commander and hopped into his ever present hovercar. The car zoomed off towards the destination of the platypus's arch-foe.
Meanwhile, Drakken was outlining his newest plan for his guest.
"Research has shown that a vast number of people spend their time on Internet social networks" Drakken said "even me."
"Oh, like MySpace and whatever" Doofenshmirtz said "I have one of those pages, but people usually only visit to mock me."
"My plan is to take control of these sites, brainwashing all of the users into naming me ruler of the world" Drakken explained.
"Since they've been on the computer for so long, as least you know their brains will be mush" Shego added.
"Unfortunately, I haven't been able to come up with a way to brainwash people through the computer" Drakken said "my previous forays into mind control have been more physical you understand."
"This would be a great use for my new Slave-Inator" Doofenshmirtz said.
"Pardon?"
"It's this thing I invented to get people to celebrate my birthday" Doofenshmirtz explained "it makes people do whatever you want. I was working on a more compact version, but I can't seem to get it to work right."
"Hmmm, perhaps if I took a look at your Slave-Inator, I could get it to function properly" Drakken explained "then we could hook it up to the computer to emit a worldwide signal through all social networks!"
"Sounds like a day" Doofenshmirtz replied "I just hope Perry the platypus doesn't show up to stop me. That little guy always seems to find me wherever I go."
"Yes, we'll have to do something about that little pest" Drakken said he thought for a few minutes, and then a wicked grin came on his face "ooh, and I just had a brilliant idea!"
"Involving a platypus? This I gotta hear" Shego said.
"Come doc, to my lab, we need to prepare if that annoying little mammal does show up" Drakken said, as he left the main room, with Doofenshmirtz close behind.
"I'm not fighting a platypus" Shego told him "it's in my new contract, 'no battling animals of any kind.'"
"Oh, I don't expect you to battle him" Drakken said "indeed, if my plan works, he'll be working for us."
"O-kay, I think Dr. D has finally lost it" Shego said, watching as he and Doofenshmirtz left the room.
Eventually, the car containing the Fletcher-Flynn's pulled up outside the Possible household.
"Now you kids behave while we're on business" Lawrence said "we'll be back in a few days."
"You heard dad" Candace told her brothers as the car pulled away "don't make any trouble!"
"I'm still trying to figure out what I want to do" Phineas told her "inspiration's not as easy when you're in another city."
Candace ignored him and knocked on the door. In a few minutes, Mrs. Possible opened it.
"Oh, you must be Kim's friends from out of town" she said "Kimmie, your friends are here!" she called upstairs.
"Nice house you have here Miss Possible" Candace said.
"Thank you" Mrs. Possible replied "but you should've seen it before the aliens destroyed it."
Candace decided not to ask and instead went looking for Kim. She didn't have long to wait, as the familiar redhead soon made her way down the stairs.
"Kim, so happy to see you again!" Candace said, grabbing her in a hug "I'm sorry, but I had to bring these two" she added, pointing to Phineas & Ferb.
"Hey Phineas, hey Ferb, nice to see you again" Kim said.
"Likewise" Phineas replied "me and Ferb are looking forward to another adventure like the one we had last time."
"I don't know if anything like that is going to happen" Kim explained "things are usually pretty quiet around here."
"Don't annoy Kim, Phineas" Candace said, "how about a tour of the house?" she asked, turning to Kim.
"Okay, come on" Kim said, with Candace following close behind.
"C'mon Ferb, there's gotta be something we can do around here" Phineas said, as the two boys went to explore the house further.
Meanwhile, Perry had discovered the location of Dr. Doofenshmirtz and tracked him to Drakken's new lair. Figuring that the door probably had a number sequence lock of some kind, he decided to try a nearby window and effortlessly parachuted into it.
He was on full alert, however, certain that Doofenshmirtz might have a trap ready for him. However, no security measures appeared to be activated. That concerned him a little, but not enough to deter him from his search.
He made his way to the main chamber, and noticed his foe near a large table containing a computer and other odds and ends.
Since Doofenshmirtz's back was to him, Perry was able to sneak up on his nemesis and flip up onto the table.
"Ah Perry the platypus, what an… well you know" Doofenshmirtz said "I'm very busy with my new evil invention, the Loose Change-Inator!" he said, producing a ray gun-like device from behind his back "with it, I can steal all the loose change in the Tri-State area. Then I'll always have bus fare, and not have to worry about people laughing at me!"
After the mad doctor finished, Perry leapt in the air, and knocked the device from his hands with a kick.
"Ahh, my ticket to unlimited bus travel!" Doofenshmirtz yelled, as he made a play for the device.
On the ground, Perry knocked it aside with his tail. Doofenshmirtz went after it, and Perry tripped him with his tiny leg.
"Oh come on, did I really do anything that evil?" Doofenshmirtz asked, "can't you just let me have this one?"
Perry thought about it for a moment, then retrieved the device and gave it to his foe.
"Thanks Perry the sucker!" Doofenshmirtz said, "so long!"
The doc didn't get far, as Perry used a grappling rope from his fedora to lasso his legs and knock him to the ground. As he did, the Loose Change-Inator exploded.
When the smoke cleared, Doofenshmirtz appeared worse for the wear, save for one little difference; his head was now separated from his body.
"Curse you Perry the platypus!" Doofenshmirtz's head said, in a gradually lower tone, while his body began to melt.
Perry investigated the pile of green goo that was once his nemesis, sticking one of his fingers into it. That proved to be a mistake, as he was quickly stuck; his attempts to free himself only led to him being more stuck.
As he struggled, he heard the familiar voice of Doofenshmirtz from behind him.
"A little stuck, eh Perry the platypus?"
Perry turned his head around and noticed Doofenshmirtz in the doorway, accompanied by the villains his intelligence said were named Drakken & Shego.
"I told you my synthodrone copy of you would work" Drakken said, as he and Doofenshmirtz approached the helpless agent.
"I'm actually surprised that you used one" Shego commented "you haven't used one of those things in ages."
"That's because it's difficult to get the materials to make their chemical interiors" Drakken explained "I was lucky I had enough left for even this one."
"Looks like you fell into our little trap" Doofenshmirtz teased his nemesis "and now you're probably wondering what my real plan is, aren't you?"
Perry nodded. "Oh you'll find out" Drakken replied "namely because you'll be a large part of it."
He then produced the handheld Slave-Inator and pointed it at the helpless platypus. Despite his best efforts, the mammal agent was soon under its' power.
"Ha ha, it worked, I knew I could fix it!" Drakken said "and you doubted me Shego."
"Ooh, you took control of a tiny mammal, I'm so impressed" Shego replied sarcastically "speaking of which, why do we need him again?"
"All part of the plan" Drakken explained.
Meanwhile, Doofenshmirtz looked at his melted synthrodrone double "poor guy, he was so young" he commented. "Funny thing, I actually did build a Loose Change-Inator once, but it would only attract pennies, and the stupid bus drivers won't take pennies."
"Don't I know it" Drakken replied.
Next time, Candace acts like a creepy Kim fangirl, while Phineas & Ferb take a trip to Bueno Nacho and have their first ever nacos. Again, please offer suggestions.
