When Doof woke up, he felt…different. His head didn't hurt at all anymore, and that was a good thing. Perry walked over to see if he was alright. Doof looked down at him. Wait…down? Why was Perry so much smaller to him now? He got up and ran to the nearest mirror. Doofenshmirtz was shocked by what he saw. It was him…but he was human again! He couldn't believe it. He stood there, staring at his reflection for a few moments. Perry was astonished to realize that his nemesis was crying!
"Ggggggggg?"
Doof looked down at Perry, and cried more.
"Oh Perry!" the distressed doctor said, dropping down to his knees. "I'm a stupid, hideous human again! I really enjoyed being a platypus, like you. Now I have to be a stupid failing evil scientist again!" he said between sobs.
"Ggggggggg…" Perry chattered again.
"Oh, right. I can't understand you anymore. I'm really going to miss that…" Doof said with a sigh.
Perry reached into his pocket and took out the mini mind-reading helmet, and he planted it on his head under his fedora so Doof could understand him.
"Why are you sad?" he asked his nemesis. "I had to turn you back to a human to keep you alive. I'm sorry about that. Truthfully, I liked you better as a platypus too, but I still love you whether you're a human or not." Perry said, tears glistening in his eyes now too.
Doof picked Perry up in his arms and hugged him close to his chest, and Perry hugged him back. Perry was purring, and it surprised Doof that he wasn't purring as well. Then he remembered he wasn't a platypus anymore. Having to be a human again would take him some getting used to.
After they broke their hug, Doofenshmirtz smirked.
"It was a lot sweeter hugging you when we were the same size you know." He said, which made Perry grin too.

The next day, Perry, Doofenshmirtz, Phineas, Ferb, Candace, and Isabella were all in Perry's base underground. Major Monogram and Carl had fired up the memory eraser, and the kids were saying their goodbyes to their new friends before having them wiped from their memories forever.
"Goodbye Perry." Phineas said. "I'll always miss you as a secret agent, even though you are a great pet."
"Yeah." Candace said. "I just hope I'll at least remember not to treat you so terrible anymore."
"Thanks guys!" Perry thought. (he still had the mind-projecting helmet on) "I'll miss being an agent around you. And thanks for helping me."
Phineas, Ferb, Candace, and Isabella all gave Perry a big hug at once, and were about to get their memories wiped when Phineas remembered something.
"Oh yeah! I forgot about you Doofenshmirtz!" he said, and they all went over and gave him a big hug too.
Doof was annoyed at first, but then smiled and hugged the kids back.
"Even though we only really knew you as our pet, you must be a nice guy to have Perry as your best friend!" Phineas said.
"Thanks." Doof said. "I'll really miss you guys too. Oh, and do you think you can get any better tasting platypus food for Perry here?" he said, winking at Perry.
Phineas laughed. "We'll try. Goodbye!" he said, and all four of them turned to Major Monogram, who placed a helmet on each of them and began erasing their minds.
"Agent P," Major Monogram called the platypus to attention. "If I could have a word with you…"
Perry reluctantly walked over, arms crossed. He was still a little mad at his boss for not caring about anything but his stupid agency, but he listened anyway.
"Agent P, I'm so sorry for what I said. I realize now that this isn't just a job to you, it's your life. I gave you your host family and nemesis as mere assignments, and I thought that was all you ever thought of them as. But now I realize the true bonds that you've made with them, and the bonds they've made with you. If I ever knew you loved them the way you do, I wouldn't have been so mad that you blew your cover, because now I see that you only did it to save a friend. But I guess I was being too hard on you, and the other agents. The damage is done, and I should punish you for this, but I just can't find it in my heart to split up the greatest relationship between enemies I've ever seen. So I guess I'll let it slide. I'm so sorry Perry. Will you ever forgive me, and come back to the agency?"
Perry was touched by his boss's words. Finally, he understood the way Perry felt about his family and his nemesis. He couldn't say no. Perry held out his hand, and Major Monogram shook it.
"Welcome back Agent P!" he said gleefully.
"Wow, this is boring. What is this, a soap opera now? Ugh, I should have just stayed home…"
Perry and Monogram turned to Doof, who was standing across the room from them. After he realized he was being stared at, he blushed.
"Ha, ha, oops." The doctor said. "I forgot to take the mind reading helmet off…" he said, reaching into his hair and pulling out the little helmet.
Monogram went over to help Carl with erasing the minds of the kids, and Perry walked over to his nemesis.
"So, what's going to happen with us now?" Doof asked. "Are we friends, or enemies, or what?"
Perry shrugged. "What do you want us to be Doof?" he asked.
Doofenshmirtz thought for a minute. What did he want them to be? He loved being his nemesis, but this whole incident had got him to find his true feelings for Perry. Being his friend was great. It cleared up all the complicated frenemy stuff, plus it made him happier then when he was fighting Perry. It's almost like they were always meant to love rather than hate each other. Nothing made Doof happier then spending time with him, and he really was willing to give up evil for his new-found friend. But being enemies was what held their relationship together for so long. Should they really just drop all their negative feelings so suddenly? Would it affect the way they saw each other as friends? Doofenshmirtz pondered for a moment, then knelt beside Perry.
"Perry, I love both sides of our relationship. I could never choose between being your friend or your enemy. I know we both enjoy being friends a lot more, but it would break the special bond we have. I think we should keep our frenemy relationship exactly the same. What do you think?" Doof said, looking deep into Perry's big brown eyes.
"I couldn't agree more!" Perry said, jumping into his nemesis's arms and giving him the most meaningful hug he had ever give anyone.
"AAAWWW!"
Perry and Doof stopped hugging to see Carl staring at them adoringly.
"Do you mind?" Doof said, obviously annoyed.
Carl blushed. "Sorry!" he said quickly, and went back to helping Major Monogram.
"Geez, why does everybody think that's so 'adorable'?" Doof said. "We're just hugging!"
Perry laughed. He knew everything was going to go back to normal.
***
After everything happened, everything did go back to normal for Perry. Better than normal. Phineas and Ferb went on with their amazing projects as normal, and Candace went back to trying to bust them as normal. Perry didn't want them to forget everything that had happened, so he had told Monogram and Carl to leave in the parts about 'Doofy'. He scribbled down a note saying that Doofy's owner had taken him back so they didn't get worried thinking he ran away or anything.
As for Doofenshmirtz and Perry, they now had a stronger 'best friends' bond then ever. But Perry did have to get used to Doof not being there at the Flynn Fletcher house anymore. He was actually starting to like his nemesis hanging out with him, and sleeping in his bed at night. But the platypus still slept great every night, knowing that his life couldn't get any greater if he wanted it to.
THE END
Doofenshmirtz: "Hey! Wait a second! This can't be the ending already! I got turned into a platypus, yet I still didn't get a cool theme song like Perry!"
Doo-bee-doo-bee Doo-bah
Doo-bee-doo-bee Doo-bah
Doo-bee-doo-bee Doo-bah
Doo-bee-doo-bee Doo-bah
He's a middle aged mammal,
A Perry lovin' platypus of evil
He makes failing inators,
That Perry destroys every day-ay-ay!
Even though he lacks mad skill,
He's got a beaver tail and a bill
And he drives his nemesis crazy, when ever he hears him say:
"Curse you Perry the Platypus!"
He's Doofy!
Doofy the Platypus!
He's Doofy!
Dr. D!
Doofenshmirtz: "Okay, that's better. Hey, what do you mean by 'failing inators'?"
