Helping thy Enemy

Perry is sick so Phineas and Ferb try to make sure he gets rest. But all forms of comfort disappear and the only place to get it is from Dr. Doofenshmirtz. It's expensive, but maybe the two brothers can help him with his new inventions as payment...

Chapter One
Candace narrowed her eyes and creeped down the hall to the stairs. It was already 10 o'clock...there was no construction going on, nothing! Not even a TV was on, no music, she had even checked outside to see if they had ended up in space or something, but no. The house was on the ground and everything seemed...normal. But normal wasn't...right in the Flynn-Fletcher house. Phineas and Ferb would be building their daily project by now. They weren't in their rooms...in fact, Ferb's toolbox was still in there, untouched.

"Phineas? Ferb?" she called, scared she might set something off.

Suddenly they poked their heads up from behind the kitchen counter.

"Shhhh." Phineas said as Ferb put a finger to his lips. "Perry's trying to sleep."

"What?" she whispered harshly, putting her hands on her hips, but the two had already disappeared behind the counter again. She sighed and walked around it quietly, spotting Perry on a pillow, his eyes half open and breathing loudly.

"He's sick." Phineas said softly, frowning. "We thought we'd keep him company, quiet company, he's been trying to sleep all night, moving everywhere, and he keeps laying down near us so we figured we'd go next to his bed."

"Well, maybe we should take him to a vet." Candace said, going on her knees to Perry and stroking him. The platypus let out a soft sigh and she stood again, noticing the two were still in their pajamas.

"Mom is going to take him when she gets home in a few minutes, she went off early before we got to tell her." Phineas explained. "Now hush!"

She rolled her eyes and walked away back to her room to go on the phone and talk to Stacy.

Phineas watched Perry, worried. What if he...went away forever before his mom came home? How did he even get sick? He was really hot, but they couldn't understand him so they didn't know what he wanted. Though right now he probably needed rest and comfort.

Suddenly the platypus stood and walked away to the living room. Phineas and Ferb watched as he climbed on the couch, curling into a tight ball, his head poking out to look at them. That's when it happened. There was a bright flash of green light and the couch seemed to shift, along with the floors and curtains. Immediately Phineas and Ferb stood to investigate when Perry jumped off the couch and landed with a smack on the floor.

"Ouch, that looked like it hurt!" Phineas said, running over to pick him up. He froze when his feet suddenly felt cold. Ferb nudged him and pointed at the ground. The once carpeted floor was now cement.

"That's...weird..." Phineas said, putting Perry on the couch. He picked him back up when he saw the couch was now a giant green cement block shaped like it. "Weirder..." Ferb touched the curtains which were now made of glass when they heard a shout.

"Phineas! Ferb! Why is are all of my things rocks?" Candace shouted, running down the stairs.

"What do you mean?"

"My bed is a giant block! My stuffed animals, they turned into hard wood! Ducky Mo-Mo is a pine cone! What did you guys do?"

"We didn't do anything!" Phineas said quickly. "But now Perry doesn't have anywhere soft and warm to lay..."

Ferb nudged Phineas. "Perhaps some fresh air will help, the grass is sof-" he cut himself off when he looked outside. All of the grass outside seemed to have turned into dull needles and woodchips.

"That's...disturbing..." Candace said. "It's like everything that's comfortable turned hard and...uncomfortable I guess..."

Phineas turned on the TV to see if they said anything on the news. But instead of the news popping up, a man in a lab coat did, talking loudly.

"-ate Area, so now, you must buy from me, Dr. Doofenshmirtz! The first pillow, is free, and the second...the second will cost one hundred dollars! And they're tiny too, so you'd have to pay like...500 dollars to get enough for a normal person's head, that's a lot of money. BUT YOU HAVE NO CHOICE! Come to Doofenshmirtz Evil Incorporated, TODAY!"

"Say, he looks familiar." Candace said.

"Well, I know what we're doing today!" Phineas said to Ferb. "Let's go buy a few pillows for Perry!"

"Phineas, that stupid, those prices are unreasonable! I mean, where do you even get the money for those projects of yours?"

They all stared at each other for a full minute, then Phineas and Ferb went upstairs to change into their usual attire. Phineas opened a drawer and reached for a shirt. His hand brushed up against glass. He picked it up and saw all of his clothes had turned hard and unable to be worn.

"Huh, well Ferb, I guess we'll spend the day in our jammies." he said. Neither of them seemed bothered by it. "Come on, let's take Perry with us, maybe we can appeal to that guy's better nature. We're also the only soft things he can cuddle against so I guess it'll work out."

Ferb nodded and picked up Perry, allowing the platypus to get comfortable in his arms before moving to follow Phineas outside of the door. He could've sworn Perry looked a little worried, but it might have been because he was sick. They were going to originally ride their bikes, but the seats had turned hard and hurt, so they walked instead. It wasn't that long of a walk, and arriving at the building didn't take long at all. Only a few people were there, and they were able to go past all of them easily.

"Excuse me!" Phineas said to the guy who had shown up on TV.

"Yes? What? Children? We have little kids coming in here now?" he said with some sort of German accent. "Yeesh, what kind of money do kids make nowadays? Oh look you have a little platypus."

"Yeah." Phineas said, amused. "He's sick though, and we need a pillow to keep him comfortable so he can rest after his visit to the vet..."

"Yes, well, what do you think everyone else is here for? You'll have to wait in line like them." he said. "And my pillow-inator is running a little slow so it's going to be a long wait."

"Pillow-Inator? Is that a machine?" Phineas asked while Ferb cocked an eyebrow at the name. "Say, Ferb and I are good with machines, maybe we can help it run faster!"

Perry chattered suddenly and flopped out of Ferb's arms onto the floor.

"Perry! No, bad boy, stay." Phineas said worriedly, picking him up. It was easy since he seemed too weak to walk.

"Your platypus is named Perry too?"

"Um...yeah, do you have a pet platypus?"

"No, but I have a platypus as my nemesis, his name is also Perry and he has a little secret agent hat."

"Cool." Phineas said, glancing at Ferb. "Now, about that machine, can we have a look?"

"Have a look? You two are just kids, take a look at yourselves, one of you is wearing feety pajamas!"

"Hmm, that's never stopped us before." Phineas said as Ferb shifted to look at his own feet. "Though we haven't built anything in our pajamas before, I'm sure the results will be the same. Come on, just take us to it, for a poor, sick, platypus!"

"Fiiine. Come on, follow me." Doofenshmirtz sighed, turning and motioning for them to follow him.

They all stepped into an elevator, gitchee gitchee goo playing in the background. When the doors opened, they were in a large room with a machine in the center trembling. After a moment, it spit out a smoking pillow.

"That...does look like a problem." Phineas said, placing Perry on the ground. He wasn't exactly sure how to fix a machine he and Ferb hadn't built. Hopefully Ferb did since he was already next to it, collecting a bunch of tools he found around the area.

"I didn't say you could touch my things." Dr. Doofenshmirtz said, looking annoyed while Ferb pulled off a few parts from the machine.

"Look, all you're doing is messing things up! You're lucky I can build another one later if you mess this one up...I just need to get the blueprints, money..."

He babbled on and on and Phineas went over to Ferb to see what he could do to help. Ferb seemed to know what he was doing and was quickly rewiring everything, so Phineas went to check on the programming.

"You need a serious upgrade!" Phineas said, pulling out a small chip.

"What are you talking about? That's the best there is...and that I can afford."

"Worry not, Dr. Doofenshmirtz, we'll take care of it!" Phineas assured. Ferb handed him a new chip from a wallet he was carrying. "I'll reprogram this one we have a bit, then your Pillow-inator should be raring to go!"

Doofenshmirtz crossed his arms and watched as they worked, Phineas had already finished reprogramming and the two were finishing up. Phineas froze, then looked around.

"Hey, where's Perry?"
