"If we can get a hold of the Amulet of Juatchadoon, we might be able to use it to send him back where he came from" Rhode Island suggested.

"To do that, we'd need some kind of magic to hold off his," Medieval Phineas explained "and we don't… oh wait, Isabel! She's magical."

"I can't be of any help," Isabel said sadly "my magic is only good as a water sprite, not a human."

"So just turn back into a water sprite," Medieval Phineas suggested "I never did understand why you made yourself bigger in the first place."

"It's because…well…I like you," Isabel explained "I found myself attracted to you after our first quest, and I wanted to spend more time with you. So I found this spell that would make me human sized, hoping we could be together."

"Gosh, I don't know what to say," Medieval Phineas replied "I like you too, but I like you for who you are, water sprite or human. We'll figure out some way to overcome the size difference."

"Oh Phineas!" Isabel exclaimed happily "you've made me the happiest water sprite ever. And now Malifishmirtz is in for some trouble. Shrink!"

Using her powers, the girl reduced herself to her original size, then fluttered out to face the giant sorcerer.

"Okay Malifishmirtz, now you have to deal with the powers of a water sprite, enhanced by the power of love!" Isabel exclaimed, moments before the evil wizard swatted her away like a fly.

"Isabel!" Medievel Phineas cried, rushing over and checking on her.

"The power of love isn't quite as strong as I thought," she said weakly.

"Okay, this has been fun & everything," Malifishmirtz began "actually, it hasn't, but it's time to wrap things up." He pointed his scepter at them "hope you enjoyed existing, 'cause that's over," he added, before firing wildly, causing the kids to duck for cover behind whatever they could find.

Realizing they had to act, the Perrys decided to strike while Malifishmirtz was busy. They ran over to where the Amulet of Juatchdoon was lying, and one of them pointed it at Malifishmirtz, but it didn't work.

"Nice try Perry the platypi," said a recovered Doofus Khan "but you need his spellbook to make that thing work properly. And I'm not telling you that it's on the table over…crud I just did, didn't I?"

Master Perry grabbed the book and the amulet and headed over towards the kids, while Parable and regular Perry stayed behind to fight off the remaining Doofs.

"Ha ha, it won't be long now, and then you kids will be history," Malifishmirtz said "you get what I did there, that was a pun on the word 'history', which can mean…"

"We get it," Ohio replied, uninterested.

"I guess this is it for us," Buvalvous said "before we're sucked into a void and turned into nothingness, I'd just like to say, it's been an honor to serve with all of you. Even the nerd archer."

"I also agree with what my bully companion said," Baljeetolas added.

"Usually at this point, some kind of last minute plot contrivance happens that allows the heroes to get the upper hand," Chinese Phineas said.

Suddenly, Master Perry appeared with the amulet and book; "like that, for instance."

"What do we do with these?" Ohio asked.

"I believe Malifishmirtz used his magic to focus through the amulet, creating the time vortexes which started this whole mess," Ferbalot explained "so we can use them to restore things back to the way they should be."

"Yeah, but we'd need Malfishmirtz's magic for that," his brother said "and I don't think he's going to help us."

"Just find a return spell and read it when I give the signal," Ohio said "I'll get us the magic we need."

He emerged from their hiding place "hey big and ugly, looking for me?"

"Actually. I was looking for all of you, but you'll do," Malfishmirtz replied "say 'so long.'"

He fired a magic beam, with Ohio producing the Amulet from behind his back and using it to absorb the beam; "now!" he shouted.

"Medieval dweller, hear my plea, return to your time…uh, thee," Medieval Phineas read.

Suddenly, a time vortex opened up near Malfishmirtz.

"Done in by my own magic spells; there's a lesson here somewhere," Malifishmirtz said, before the vortex began pulling him in "no! Noooooooo! Curse you Parable the dragonpus, even thought you had very little to do with thisss!" he exclaimed before he was sucked into the portal.

Doofus Khan & Doofenshmirtz, who were still busy dealing with the other two Perrys', took notice of what happened and saw their magical counterpart get sucked back to medieval times.

"Ooh, that can't be good," 1914 Doof commented.

"We'd better get out of here," Doofus Khan agreed.

However neither one got very far before the remaining Perrys quickly tied them together.

"Well, this blows," 1914 Doofenshmirtz commented "quick Norm, untie us."

"I would, but apparently, I'm not as useful as that giant me" Norm replied "why don't you get him to untie you."

"I would, but he's broken…oh, you were being sarcastic on account of how I kept insulting you," 1914 Doof replied "yeah, in hindsight, that wasn't a great idea."

"Good plan other me," Medieval Phineas congratulated Ohio "but how come everything else isn't going back to normal now that Malifishmirtz is gone?"

"I'm not sure," Ohio said "but I suspect the Amulet may hold the key."

"Well, I guess that's everything," Chinese Phineas added, before hearing the muffled & annoyed noises of the three captive Candaces "Oh right, we were so busy fighting for our lives, we forgot to free them."

"Hang on sis, we'll have you loose in a minute," Chinese Phineas said, as he pulled the gag down.

"You two are so busted when we get back to China!" she shouted "when mom and dad find out what you've done to the timestream, they'll…never believe me, will they?"

"I'd say no."

"Man, and I was so looking forward to seeing you brats get what you deserve," Candavere said as soon as she was able "oh well, right now, I just wanna get back home."

"I wish we knew how to do that," Medieval Phineas said.

"Actually the solution has been under our nose the entire time," Rhode Island explained "since the Amulet of Juatchadoon served as the conduit that allowed our various selves to meet here, destroying it should restore everything back to normal."

"That seems remarkably convenient, but let's try it," Chinese Phineas commented.

"But first, how bout some goodbyes?" Ohio said.

The group of kids and platypi gathered outside Doof's headquarters to say their farewells to each other.

"So long other me," Ohio said "it was cool meeting you; too bad none of us will remember any of it."

"Take care Ohio Flynn," Chinese Phineas said.

"So long Princess," the 1914 Isabella said "you take good care of your Phineas."

"Oh, I plan to," Princess Isabella replied "and you take care of yours."

"And I'm looking forward to seeing how things with my Phineas work out," Isabel added.

"Well other me, it's been fun," said Candavere to her Chinese self.

"If you want, I could send you one of my silk robes," the Chinese one suggested.

"Yeah, can't travel through time, remember?" Candavere replied "besides, we won't remember this conversation anyway."

"Oh yeah."

The Perrys said nothing, of course since they couldn't talk, but the modern one tipped his fez to his other counterparts. Master Perry bowed in response, with Parable not really sure how to respond.

"Hey, I know we probably won't remember any of this, but how about a picture?" 1914 Candace asked.

Everyone agreed and gathered together so she could snap one last picture of all of them.

"Say 'time travel.'"

"Time travel!"

"Okay, Master Perry, do the honors," Ohio said.

Nodding, the platypus master smashed the Amulet on the ground. Suddenly, there was a bright flash of light, and then…nothing.

"Whoa, I had the strangest dream," Ohio said moments later "I dreamed there were other versions of us from different time periods and we had to join forces to stop three versions of Doofenshmirtz."

"Me too," Candace said.

"Yeah, and me," Isabella added "weird huh?"

"Maybe the adventuring life is starting to get to us," Ohio said "we could use a vacation; I hear Brazil is nice this time of year."

"I've always wanted to go there," Isabella said.

"Then its' settled, off to Brazil!" Ohio replied.

Ancient China

"Ooh what happened?" Phineas asked, as he and other Chinese versions woke up next to the Great Wall.

"I remember coming to visit you, and then, nothing," Princess Isabella said "although I had this dream that there were other versions of us, and I was kidnapped, but you rescued me, and we battled a sorcerer version of Doofus Khan."

"Hey, I had the same dream," Phineas said "I wonder what it means?"

"Perhaps we need to lay off the egg fu yung," Ferb suggested.

"Come on Phineas let's go back to the palace," Princess Isabella said "I hope Regent Monogram hasn't been too worried about us."

Medieval Times

"Wow Ferbalot, I had the strangest dream," Phineas told his brother "but it all seemed so real. Could it have been a vision of something that happened?"

Ferbalot just shrugged his shoulders.

"Hey, weren't we fighting Malifishmirtz? Where'd he go?" Isabel asked, looking around.

"I guess we won," Phineas replied "and hey, you're back to being small! That's good, I like you that way."

"You do?"

"Sure, you water sprites are amazing!"

"Oh Phineas" Isabel replied, visibly blushing.

"Jeez, get an inn you two" Buvalvous commented.

Back in his castle, Malifishmirtz was recovering from being sucked through the portal.

"Ooh what happened? I feel like I traveled to another time period, then was sucked through a vortex back to this one, losing all my memories in the process. Man, that was oddly specific."

He walked over to his magic cauldron where he could see the others. "Enjoy your victory while you can, because soon, I shall regroup, and nothing will stop me from…you know what; I can't do this on an empty stomach. I'm getting lunch, then revenge" he added, before heading off for a snack.

Panama

"There, our plane to Brazil is all packed," Ohio said "this should be a fun, and hopefully adventure free trip."

"Right, nothing but relaxation for us," Isabella added.

"Hey guys, check this out," Candace said. The three kids headed over to see what she wanted.

"I got my film developed earlier, and I thing they did a bad job, because there's clearly something wrong," she explained, showing the pictures.

Indeed, many of them featured scenery, but little else. But the oddest was one that showed Ohio, Rhode Island, Isabella, & that fez-wearing platypus posing for a picture, but there was clearly a large gap between them. Equally odd was the fact that they were resting their elbows on something, but it didn't appear in the shot.

"Hmm odd, I think I'd remember taking this picture," Ohio said "and it's like something was taken out of it. But how, and why?"

"Perhaps there are some things we were not meant to know," Rhode Island commented.

"That or there's something wrong with the darkroom at the newspaper," Candace replied.

"Let's go with that one," Ohio said "come on, let's just go and forget about for right now."

So they headed off into the plane and prepared for their trip, their experiences with their other counterparts only believed to be a dream. Such was the case in the other time periods as well, their meeting and subsequent friendship and battles with Doof considered just a story concocted by their minds. Perhaps it was for the best that they not remember, as doing so could threaten the stability of space and time itself.
