But Drakken had no idea Kim & Ron were right on his trail. However, fate would soon intervene and allow the two heroes to meet some new friends.
"Shouldn't be long now" Kim said "if this Doofenshmirtz is anything like Drakken, his building will be clearly labeled and easy to find."
"Why do villains never do a good job of hiding their secret hideouts?" Ron asked.
"Beats me" Kim replied "maybe they figure nobody can find it since it's a 'secret hideout.'"
Before they could have any further conversation, a loud BANG was heard from outside.
"Aah, they're onto us, and now they've started shooting!" Ron exclaimed.
"Actually, I think the tire just blew out" Kim replied "it's amazing, this car can convert itself to go over all sorts of terrain, yet it can still get a flat."
"That's life KP" Ron said.
Both exited the vehicle and headed to the trunk. However, when Kim opened it, she was surprised by what was there, or rather, not there.
"What happened to the spare tire?" she asked "I know I always keep one in here."
Ron, meanwhile, recalled something that happened a few days earlier…
On top of a hill in Middleton, Ron & Rufus were preparing for something extremely fun and dangerous.
"Ready buddy?" Ron asked his pal.
"Oh yeah."
"All right then, let the second annual Middleton hill race begin" Ron said. He then rolled a tire to the edge of the hill and placed Rufus in it. "Last year's champion Rufus is hoping to break his own record. Will he succeed? You'll have to watch and find out!"
With that, he rolled the tire down the hill, watching as it came to a stop by a grove of trees.
"He did it, Rufus is again hill racing champion!" Ron shouted, as he ran down to meet Rufus.
"Oh yeah, oh yeah" Rufus said, emerging from the tire and doing a victory dance.
"Well that was fun, wanna go again?"
"Yeah."
"I have no idea what happened to it" Ron lied.
"Well we're not going to get anywhere without a new tire" Kim said.
"Couldn't we just ask somebody to borrow a spare?" Ron asked "I'm sure people here are pretty friendly."
"It couldn't hurt to try" Kim replied "let's start with this house."
As luck would have it, this was the Fletcher-Flynn residence. Candace was inside, painting her nails, when the doorbell rang.
"Coming!" she yelled, getting up from her chair and heading to the door. She opened it and found Kim & Ron outside.
"Hi there, I'm Kim and this is Ron" Kim explained "our car got a flat outside of your house, and we were wondering if you had another tire we could borrow."
"Maybe, my dad knows about all that car stuff" Candace said "but he's not here right now. Would you like to come in?"
"We really shouldn't" Kim said "we're sort of in a hurry…"
"Oh, come on" Candace said, "I need some teens to hang out with, or my brothers will drive me crazy!"
"I guess we could come in for a little bit" Kim said.
"Great, 'cause Rufus and I are starving, aren't we buddy?" Ron said.
Rufus rubbed his tummy to indicate his hunger.
"Aww, what a cute little thing you are" Candace gushed at Rufus "um, what are you?"
"He's a naked mole rat" Ron explained "yup, had him since I was a boy."
"He's pretty cute for a rat" Candace said "anyway, there's food in the fridge, but don't go crazy."
After the two left, Candace turned to Kim. "That's a very cool outfit you've got on" she said "where did you get it?"
"Had it specially made, actually."
"Really? I think you and I are going to be real good friends. I'm Candace, by the way."
"Kim, Kim Possible" Kim added, shaking the girl's hand.
"That name sounds familiar for some reason" Candace replied "are you a world famous pop star?"
"No."
"International fashion model?"
"Uh-uh."
"World renowned movie star?"
"Hardly."
"Oh well, I'll remember it eventually" Candace said "come, sit down for awhile. It's nice to hang out with someone mature for once."
"What do you mean?"
"I always end up having to babysit my little brothers."
"Ahh, little brother trouble, I can relate" replied Kim.
"Well, at least yours aren't mechanical geniuses who delight in causing mischief" Candace added.
"You'd be surprised."
Meanwhile, Ron & Rufus had made themselves some sandwiches. After wolfing them down, Ron noticed the makeshift detective office outside.
"What in the name of Bueno Nacho is that?" he asked, as he and Rufus headed out for a closer look. It was then he was approached by a pointy-nosed kid wearing a deerstalker hat.
"Oh hey" Phineas greeted him "I've never seen you around here before."
Ron looked down at the red-headed kid "yeah, me and my girlfriend were on our way downtown when our car got a flat. Uh, interesting shaped head you've got there."
"Thanks, I guess" Phineas replied "did you say your car got a flat tire?"
"Yeah."
"Me and my brother Ferb would be happy to fix it for you. Our detective business hasn't been doing well anyway. Hey Ferb!"
Ferb popped his head out from under their desk "this guy needs a tire changed on his car!"
Ferb quickly left the desk and headed to the garage; seconds later, he emerged, rolling a tire along with him.
"Okay, now let's look at that car of yours" Phineas said.
"Um, aren't you guys a little young to be fixing cars?" Ron asked.
"Yes, yes we are" Phineas replied.
A few minutes later, Phineas and Ferb were at the Sloth 2.0 and changing the tire, as Isabella & Ron looked on.
"This is a really neat car" Phineas said, as Ferb undid the lugnuts "reminds me of the one we made for the race, huh Ferb?"
Ferb nodded and continued on his way.
"Can he talk?" Ron asked.
"Yeah, he just chooses not to" Phineas replied.
"So, Mr. Ron, what brings you guys out to Danville?" Isabella asked.
"I can't say, it's kind of top secret" Ron explained.
"Top secret?" Phineas asked "what are you, a spy?"
"Yeah, I'm a spy" Ron said nervously, "me, an average teenager, am a spy. Ha ha, man you kids are really funny."
"OK, you're not a spy" Phineas said unconvincingly, as he removed the old tire "but hypothetically, if you were a spy, what would you be doing here?"
"Well if Kim and I were spies, which we're not, we'd be here 'cause Kim's nemesis is in town. He hooked up with some mad scientist that lives around here or something. I mean, he would, if he was real, which he isn't. 'Cause I made him up."
"Rrright" Phineas replied, as he put the new tire on the car. Ferb then screwed the lug nuts back on. "Okay, your car's all ready to go" Phineas replied "if you like, we can check under the hood for ya."
"You two remind me a lot of Kim's brothers" Ron said "in fact they built this car. A pair of little geniuses, those two are. They even got bumped ahead into high school."
"They sound like my kind of guys" Phineas said from under the hood "hey Ferb, hand me a crescent wrench."
Meanwhile, in the backyard Rufus had been left with the boys' pet platypus, Perry.
"Hey" Rufus said, but Perry could only respond with his usual sound.
The mole rat decided this wasn't any fun and headed off to rejoin Ron. Until he noticed Perry looking around the yard, then running off. Curious as to where the mammal was going, Rufus ran after him.
"Whoa!" Rufus said, following the mammal as it stopped by a nearby lawn gnome. He barely had time to react when Perry pulled the gnome forward, activating a trapdoor in the ground. Rufus watched as the platypus put on a fedora, and headed down the trapdoor. The curious mole rat jumped in right after him.
"Whee!" he shouted, as he traveled down the chute. When he came out, he landed on Perry's lap in a high-tech room. The platypus looked down on his visitor with both surprise and displeasure.
"Hi" Rufus replied, waving one of his paws. Before Perry could do anything, Major Monogram appeared on the big screen.
"Agent P, we've received word that Dr. Doofenshmirtz has…" he paused upon noticing the mole rat sitting on Perry's lap "excuse me Agent P, but what is that on your lap?"
Perry shrugged his shoulders.
"Karl, come here" Major Monogram ordered his cameraman "what is that thing on Agent P?"
"I think it's a naked mole rat sir" Karl replied "I had one when I was a boy. They make great pets, especially for people with allergies to fur."
"Okay, so what's it doing here?"
"From the looks of it, I'd say…sitting."
Major Monogram groaned "I can see that. The question is, who does it belong to, and why is it here?"
In the next chapter, Phineas & Ferb decide to prove their detective skills by capturing Drakken, while Rufus goes on a mission with Perry.
