A small green Zündapp Janus 250 takes a deep breath, glad to be back in his lab. The jailbreak couldn't have gone any smoother. There had been a few close calls no thanks to those daimler bumbling hench-cars, but he was out and that was all that mattered.

"I'm home mein babies," Professor Zündapp murmurs as he drives around his lab, making sure none of the highly expensive equipment or works in progress were damaged during his absence. He stops in front of what appears to be a large, nearly-finished ray. "Soon…very soon…" he says with a wry smile.

"Hey, Professor," an orange AMC Gremlin says as he enters the large room, interrupting Zündapp's thoughts.

The Professor turns around to face him and with an annoyed sigh he asks, "Vat is it Grem?"

"We were just wonderin' when you were wantin' us to leave to, y'know, spring Axlerod."

Zündapp gives a short bark of laughter. "Ve have no need for him. He can rot in prison for all I care."

"Professor?"

"I got mein money from that fool, zat is all I care about. He is incompetent at best. Peh! Who programs a bomb to say their name if it is deactivated?" he snorts and turns back to face the ray. "No, I have something much bigger planned. Ze only reason I signed up to vork for zat… fool vas to acquire ze needed funds for ze last piece to finish mein ultimate creation. And zat arrived today."

"A ray gun?" Grem asks incredulously.

"Nien. It is much more than that."

"Then, what is it?"

A pause.

"Vat are your thoughts on alternate dimensions?"


"So Ferb, any ideas on what we should do today?" a triangle-headed boy with bright red hair asks the just as oddly-shaped head boy with green hair sitting next to him under a tree.

Ferb just shrugs his shoulders.

"Hm. Well, we already gave Perry a bath today. I still don't know why we woke up to him smelling like garlic…"

Perry chatters, remembering Doofenshmirtz's late-night scheme last night involving garlic-scented throwing stars and Doof's worry over Vanessa's obsession with a certain series of books and movies… and an irrational fear as always.

"Phineas!" a red-headed teen calls from the sliding glass door leading into their house.

"Hey Candace!"

"Remember, no shenanigans today! Mom and Dad may still be on their trip to the Antique Convention, why anyone would want to go to something like that is beyond me, but I'm still in charge and Jeremy is coming over today. I do not want to spend the day chasing after one of your little contraptions when I'm trying to have quality time with my boyfriend!"

"Candace, we wouldn't dream of making you miss your date with Jeremy," Phineas reassures his older sister.

"Well, good," Candace says and closes the door, off to get ready.

"Hey Phineas! Whatcha' doin'?" a dark haired girl asks as she opens the gate to Phineas and Ferb's back yard.

"Nothing yet Isabella. We were just trying to think of something to do. Any ideas?"

"Well, actually… My family's leaving on vacation today so I came over to say good bye."

"Oh, that's right! Man, I had totally forgotten… Where you guys going again?" Phineas asks.

"We're taking a road trip down Route 66. My dad's idea," Isabella explains.

"Wow, the Mother Road! Well, have fun Isabella!"

"I'll try," she says. "…Are you going to miss me?"

"Well, of course!"

Isabella gasps.

"You're one of our best friends. How could we not miss you?"

"Oh…" Isabella sighs. Our… we…

"Isa! Come on! It's time to go!" Isabella's mom yells from across the street.

"Well… gotta go. See you guys in a couple of days!" she says and turns to leave.

"Bye Isabella!" Phineas shouts as Ferb simply waves his hand.

The Garcia-Shapiro's car soon pulls away, horn honking a goodbye to their neighbors.

"Hey Ferb! I know what we should do today! Isabella's family trip gave me an idea what if we-" Phineas starts to say. But before he can finish his sentence, a bright green beam comes from seemingly out of nowhere and hits the two boys making them disappear right before their platypus' eyes.

Perry, not caring if anyone sees him, immediately jumps up on his hind feet and looks at the spot where his owners were sitting just a few moments ago with clear concern. Could Doofenshmirtz have something to do with this? Could he have already created a new –inator? Maybe this could even have something to do with the adventure they had gone on just a few days prior….

Determined to get answers, the monotreme dons his fedora and opens the tree tunnel (which Carl had yet to seal from when the boys discovered his lair for the first time).

"Agent P?" Major Monogram asks from the screen, somewhat surprised at seeing his top agent reporting for duty. "I thought you already defeated Doof today. We don't have any information about another scheme of his yet…"

Perry ignores him and just runs for his new rocket car that had just gotten back from the repair garage the other day. He starts it up, more careful of the accelerator this time, and plots a course to Doofenshmirtz Evil Inc.

"Agent P!" Monogram says from a slightly smaller screen in the rocket car. "What is going on?"

Perry looks at the screen, biting his lower beak and the worry clear on his face.

"Is it the boys?"

He nods his head in the affirmative.

"And you think that Doofenshmirtz might have something to do with it?"

A shrug.

"I see. Well, Agent P if there is anything we can do to help, just let us know. Monogram out."

Perry salutes Major Monogram before the screen goes dark and then continues on his way to confront his long-time nemesis about the disappearance of the two boys that mean the world to him. If he finds out that Doof is somehow responsible… it won't be pretty.


Professor Zündapp had been waiting for this day ever since he made the discovery of alternate dimensions just a few years ago. Sure the inhabitants of the dimension he had found were very strange looking and the cars there seemed to be nothing more than dead heaps of metal, but two inhabitants of the other dimension had caught his eye.

It had been just a few months prior when he had been able to get his first glimpse of another dimension. He had had the theory for years but he was able to finally prove it. He knew that nothing could be moved between the dimensions yet, but he was able to look. His first look had astounded him.

First there had been the shock of the structure of the inhabitants of the alternate Earth. They hadn't even looked like cars for the Manufacture's sake! No wheels, no axles, no metal bodies… Just very strange looking creatures. The cars in that dimension didn't even seem conscious or capable of speech, much less moving without the help of the other creatures.

Then he had seen them. They had looked even stranger than the rest of their kind, but that wasn't what had caught the Professor's attention. What he had seen was two creatures who were capable of preforming surgery and modifications on a car that went far beyond what could be done in his own dimension. He had seen the car that the creatures had worked on go from your average every-day car to a racecar capable of incredible speeds.

When he had seen enough, Zündapp had powered down the device he had created to allow him to look into other dimensions. The more he thought about what those boys had done, the more he was determined to find a way to bring them to him. If he could only figure out how, he could force those creatures to do repairs on his miserable Lemon body. And why not stop there? he had thought. I could even have them do modifications to make me ze strongest and fastest car in ze history of car-kind! Vit them at my command I could show ze world never to mess vit Lemons ever again!

He had started work the very next day to modify the device to allow him to bring the creatures to his own dimension. He had only taken on the commission from Axlerod to fund his device.

Yes, he had looked forward to this day for a long time. So it was most defiantly not welcome when just a few seconds after firing his device, alarms start blaring. He had programed the alarms to alert him if the slightest thing went wrong.

"Vat is going on?" he demands of one of his various Lemon-type hench-cars who was parked in front of one of the monitors hooked to the device.

"I don't know Professor!"

The Zündapp growls at the car's insufficiency and makes him get out of his way so that he can look at the monitor. He checks the 'vitals' of the machine, making sure nothing is in danger of blowing up or causing harm to himself or his facilities. Everything seems to be normal in that respect. So why were the alarms going off? He switches the screen to monitor the creatures' position in the space-time continuum. He blinks, trying to adjust his eye sight, not believing what the monitor is telling him.

The creatures were most definitely in the same dimension as him now, but not in the place he had programed the ray to place them, which would be right in his lab. According to the monitor, they had been placed somewhere in the Arizona desert.

"Vell, this just makes things a tad more complicated," he sighs. "Grem. Acer. Ready ze jet. Ve are taking a trip to ze States."


Phineas groans. My head… he thinks as he sits up, rubbing his temples in hopes of ridding himself of the headache he has woken up with. He looks around and freezes. I don't remember going to the desert. How…? Using his arms to get himself into a standing position, Phineas takes a quick look at his surrounding area, making sure he isn't in any immediate danger. Nothing but sand and a road that seemed to stretch on for miles. But…Where is Ferb?

"Ferb!" Phineas calls out as he looks around, hoping to see a spot of green in the mostly brown and rust-colored landscape. Squinting his eyes against the sun, he sees it. The patch of green and purple shorts. "Ferb!" he exclaims and runs the few yards that separate him from his step-brother. "Bro, you ok?" Phineas asks, shaking an unconscious Ferb's shoulder.

Slowly, the green-haired Brit comes to. He too takes in their surroundings with obvious confusion, something not normal for the British boy.

"Phineas, where are we?"


A/N- I've had this idea floating around in my head for a while now so I finally sat down and wrote it! In my opinion, Cars does not have enough cross-overs.

Let me know what you think! I know that not as many people read cross-overs so your feed back will really help.

And yes, I plan on bringing my car puns to this story as well!

For the love of Doonkleberry Cake, review!
