Hello, readers! I have decided to start a P&F and DP crossover, if only for the distinct lack of them on the site. I love both cartoons, and a crossover between the two is just so DOABLE.

I own neither cartoon!

"So you see, Perry the Platypus, that is why I've decided to use ghosts to take over the tri-state area!" Doofenshmirtz announced, his arms in the air for dramatic effect. Perry sighed. Doofenshmirtz's back-story was over (not that he'd actually paid any attention), so it was about time to escape from his trap. Today, he was plastered to the floor by some green ectoplasmic goo, and it was going to take a lot of struggling to break free. Perry eyed Doofenshmirtz warily as the evil scientist pulled a lever. The floor began to shake as something dramatically rose out. Perry tensed. He couldn't see it very well from his vantage point, but it appeared to be very large and cylindrical shaped.

"Behold, the Ghost-Attractor-Inator!" Doofenshmirtz yelled. Perry smirked. Did the scientist really believe ghosts existed?

"When activated, it attracts ghost like a magnet. Once that happens, I'll convince them to join me and together we will rule over the tri-state-area! There's no way they could resist the temptation of joining my pure evil genius!" Doofenshmirtz exclaimed. Obviously he had thought this idea through and was certain it would work. Perry rolled his eyes. Ghosts simply didn't exist.

Doofenshmirtz seemed to read the expression on Perry's face. "And don't give me that look, Mr. Skeptic. Ghosts exist. You just watch..." Doofenshmirtz wagged a finger in Perry's direction, as if scolding him. The scientist jogged over to where the ON button on the giant cylinder was. Yep. Time to escape from the trap. Perry slithered out of the green goop, which had somewhat hardened into a shell above him. Meanwhile, the cylindrical ghost-magnet was starting up, and Doofenshmirtz was rubbing his hands together and squealing "it's working!" like an excited little girl. Perry vaulted into the air, and knocked the scientist to the ground with a kick to the face. Perry did not actually believe this particular Inator was "working", but Doofenshmirtz would be devastated if Perry up and left on him. So, he had to make it look like he was thwarting him, at the very least.

Doofenshmirtz struggled to his feet. "Perry the Platypus? How did you escape from your trap?" he asked in surprise, and then noticed that the ectoplasm had hardened in place. "Oh... heheh... I forgot that ectoplasm does that if not it constant motion... oops... heh... OOMPH!" Doofenshmirtz was knocked to the ground once more, and this time Perry was on top of him. They grappled like this for a little while, until Doofenshmirtz called a time out. "Hold on a second, Perry the Platypus! How long has it been since I started up my Inator?" Perry checked his watch. 15 minutes had passed already, and not a single ghost had been attracted to the Inator. Perry offered his watch for Doofenshmirtz to see. Doofenshmirtz hadn't been looking at the watch for more than 5 seconds when Major Monogram's face hologram appeared. Doofenshmirtz jumped back, startled, and Perry saluted.

"Agent P! We've been monitoring your fight with Doofenshmirtz, and it seems that his Inator has not attracted a single ghost in 15 minutes. We find this reason to believe that his Inator is a failure, and that ghosts simply do not exist."

Doofenshmirtz threw his hands in the air, offended. "Hey, ghosts exist!" he exclaimed. Perry rolled his eyes.

Major Monogram ignored Doofenshmirtz, clearing his throat loudly. "Because there was nothing to thwart, you are dismissed from duty and can come home early," he continued. "You of all Agents deserve this, Agent P." Major Monogram's hologram dissipated before Doofenshmirtz could protest again. Perry shrugged, secretly glad for the excuse to leave, and activated his jet-pack. He was making his way to the edge of the building when Doofenshmirtz stepped in front of him.

"That's it, Perry the Platypus? You're just going to leave on me? What about destroying the Inator?" Perry shrugged again. Doofenshmirtz sighed, defeated. It was one thing for him to have his Inator destroyed, and yet another for it to be a complete failure. He tried one more time. "Please...?" Perry saluted him, feeling sympathetic, before flying off. He heard a half-hearted "curse you, Perry the Platypus" behind him as he left Doofenshmirtz Evil Inc. behind for the day.

A/N: Well, I hoped you enjoyed that little tease. Thanks for reading!
