This story will use events and dialogue from the online Phineas and Ferb game "The Dimension of Doooom!", but I don't own the game or Phineas and Ferb as a whole.


First Dimension Perry had been instrumental in fighting Second Dimension Doofenshmirtz's invasion, but that wasn't the main reason Candace was glad to see him. She had an idea about why First Dimension Phineas and Ferb appeared entirely oblivious to the whole incident, and she knew that Perry could confirm it for her.

Baljeet seemed to read her thoughts as he observed Perry's behavior around his owners. "It has occurred to me, Sir," he said, "that had we not formed the Resistance we might have never learned about the O.W.C.A. You do not think...?"

Candace remained silent, her eyes on Perry. The platypus gave a subtle twitch of his tail, as though motioning for Candace to come with him. He then turned and walked back into the shadowy corners of the hideout out of sight.

Candace motioned for the others to stay put, then followed Perry.

"Perry?" said Candace, not certain of how to begin a "talk" with a secret agent platypus. Even when the O.W.C.A. had been fully functional and helping to oppose Doofenshmirtz, the Resistance had rarely had to verbally communicate with the agents. Most of the time, the agents had simply received orders directly from the organization itself.

In the background, Candace could hear Isabella and Baljeet striking up a conversation with Phineas and Ferb.

Once Perry was satisfied that his owners would not be able to see him, he stood up and put on his fedora. He pulled out a sketchpad and a pencil and wrote something down, then raised it for Candace to read.

Why are they here? said the note.

"We need their help, Perry," Candace explained. "Doofenshmirtz has escaped here in the Second Dimension."

I know, wrote Perry. I'm here to help stop him. He plans to invade the First Dimension again. But I don't want them to get involved unless it's necessary.

"Didn't they play a big part in defeating Doofenshmirtz the first time he invaded your dimension?" asked Candace.

Perry was already scribbling down a reply. That was different, he wrote. They were in the First Dimension.

"What's the difference?"

Perry turned the page had been writing on. We replicated their previous inventions, he wrote on the next page, and used them to fend off the Norm Bots. I had scanned their daily inventions with my hat and saved their data in my computer. We can't access the files here.

In that case, Candace realized, bringing First Dimension Phineas and Ferb here had been a mistake. Furthermore, chances were that they wouldn't be able to pull the same trick here, as her own brothers had not had as much time to create as many inventions as the First Dimension Phineas and Ferb had, and in any case she didn't know whether Platyborg had done the same to their inventions after being re-accepted into the O.W.C.A. as First Dimension Perry had done with their First Dimension counterparts'. Admittedly, it had partly been an accident that the brothers were now stuck here temporarily. They would have to decide what to do with them later.

"They don't seem to remember the Second Dimension at all," Candace started to say.

Yes, Perry wrote. The O.W.C.A. wiped their memories of that day to restore status quo, and so I would not have to be relocated.

That validated Candace's suspicions. "Is there any way you can restore those memories?" Candace asked.

This time, Perry took a moment to think before replying. I might have a way, he wrote down slowly, but I'm not going to use it for now.

They need to go home, he elaborated before Candace could question him further.

Candace said nothing for a few moments.

"So this is a different dimension?" Perry and Candace heard Phineas ask. "Why didn't you say so, Baljeet? We had been planning to find a different dimension this whole time!"

"That is Dr. Baljeet," Baljeet said under his breath.

"It's only a matter of time before they figure the rest out, Perry," said Candace, turning back to the monotreme. She knew that that was a weak argument, but she still held out for the possibility of restoring First Dimension Phineas and Ferb's memories.

As expected, Perry shook his head. Resourceful they may be, he wrote, but it's dangerous. You know that.

If we were back in the First Dimension with access to their inventions and under immediate threat, I would agree to return their memories, he added.

"But, Perry," said Candace, "Doofenshmirtz intends to invade the First Dimension. Wouldn't it be better to restore Phineas and Ferb's knowledge of the situation now than to dump this responsibility on their heads at the last minute later?"

Perry thought hard for a bit. After what seemed to Candace like several minutes, he scribbled out, We will wait the three hours until the portal can be opened. After returning to the First Dimension, I will try to restore their memories.

That seemed fair to Candace. She was about to take up the proposal when an image burst out of Perry's wrist communicator, breaking her chain of thought.

Perry held his wrist communicator up as he noticed the hologram of Major Monogram spring up. "Agent P," said Monogram, "after some digital inspection we have identified some inter-dimensional activity going on at Doofenshmirtz Evil Incorporated. It's not our dimension Doofenshmirtz's work because... uh, we seem to have forgotten about him and left him tied up in the Amnesia-inator chamber. Anyway, we figure that Second Dimension Doofenshmirtz will be invading at any moment now. You must come back and put a stop to it immediately. Monogram out."

Perry saluted as the hologram blinked out. He then looked back up at Candace and raised his sketchbook. With his pencil he scratched out his proposal and instead wrote underneath, I'll do it now.

"Excellent," said Candace. "We have to find another way back to your dimension if we're to make it in time. Could your O.W.C.A. help us? They must have portal-making technology if they could send you here."

Too risky, wrote Perry. They don't know how to control where the portal will show up.

"Hm." Candace turned back to the others. "Isabella, Baljeet, are there any alternative power sources nearby?"

"I'll look that up right away, Sir," said Baljeet, as he returned to his monitor screen. Isabella followed.

Meanwhile, Perry ran out of the shadows. With some foreboding he approached his owners.

"Perry? Why are you wearing a hat?" said Phineas in perplexity, while Ferb just stared as usual.

Perry didn't respond. He reached into his fedora and pulled out a digital camera. He fiddled around with it until one of the photos he had taken on their first adventure in the Second Dimension showed up on its screen. He had been planning to erase those photos from the camera for weeks now, especially as he had already saved them onto his computer, but the fact that few even knew that he had a camera meant that he had been in no rush to do so. He was glad that he hadn't deleted them now. Well, mostly glad, but also nervous about what he was about to do. He wasn't even certain if it would work. Feeling his own pulse speed up slightly, he handed the camera to Phineas.

Phineas took the camera, plainly baffled by what was going on. He and Ferb examined the photograph on the screen, their faces unreadable.

The two looked at the photograph for what seemed like a long, long time. Perry walked up beside Phineas and, as boys' eyes didn't leave the image, he reached up and pressed a button on the camera to show them the next photo. He did this several more times, skimming through the entire set of photos he had from that day. With each photo, Phineas and Ferb's eyes grew rounder and rounder until Perry feared that their eyeballs, which were already bulging as they were, would drop out of their sockets and onto the floor.

Finally, Phineas tore his eyes away from the camera and looked directly at Perry. "Agent P?" he whispered. Perry smiled.

"Perry!" cried Phineas. "You gave us our memories back!" He grabbed Perry in a hug. "But why? Wouldn't...?" He glanced around. "Oh, right. We're in the Second Dimension, aren't we?" Perry nodded. "So that must be other dimension Candace and other dimension Isabella," Phineas concluded, "and Dr. Baljeet!"

"Now he remembers," muttered Baljeet, still working in front of the monitor.

That clears up some things, thought Ferb, who had been standing beside Phineas quietly patting Perry on the head.

"So..." Phineas continued, still recovering from his abrupt memory restoration, "if Second Dimension Doofenshmirtz is back like Candace had been trying to tell us... what's the plan?"

"We have temporarily used up most of our power here, but we're working on a way to return you back to your dimension," said Isabella. "If Doofenshmirtz invades that dimension, you'll need to be prepared to stop it."

"And if he stays in this dimension," Candace added, "we'll be ready for him as well. Between the two dimensions we should be able to recapture Doofenshmirtz."

"The problem is," Baljeet spoke up, "we cannot seem to find an alternative location suitable to opening a portal."

Before anyone could say or do anything else, however, a new window popped up on Baljeet's screen, flashing red.

"Red alert from the Firestorm Girls," Isabella announced. "Doofenshmirtz has been spotted!"

"Where?" asked Candace as she read through the message.

"Just outside Doofenshmirtz Evil Incorporated," Baljeet answered for her. "The one in our dimension, I mean."

"Who'd have guessed?" said Candace with a hint of sarcasm. "Change of plans, soldiers. We're heading there right away."

"We're coming with you," said Phineas decisively, finally letting go of Perry.

Candace considered them for a moment. "Very well," she said.

"You had better take these," said Baljeet, pulling out and opening a small box. Inside were what appeared to be several ray guns. "Your brothers made these on the day they were recruited, Sir," he said to Candace.

"My brothers made these?" echoed Candace. She had not known about these at all.

"They are only prototypes," Baljeet went on. "We never got to use them because Doofenshmirtz was arrested just a few hours later. Your brothers had wanted to make improvements on them, but they will do."

The others all reached into the box and picked out a ray gun each. Candace examined hers with some uncertainty.

"If these are prototypes, what flaws do they have?" she asked.

"Not much, but your brothers had wanted to standardize them and optimize their firing rate and power. Right now their properties vary depending on the personality of the user."

"Ray guns that detect your personality? Cool!" said Phineas as he inspected his. "Oops." He had accidentally pressed the trigger, sending a rapid burst of red sparks shooting across the room. Perry leaped out of the way just in time, doing a back flip in midair to avoid the shot. When he landed, however, he noticed that his jet packs had been damaged. He attempted to start them up to see if they were still working. They weren't.

"Sorry, Perry," Phineas apologized. Perry waved his hand to show that it was OK. He could just get the jet packs replaced at the O.W.C.A. Granted, this was a bad time to have had them disabled.

"We should bring these," said Isabella, producing a few strangely-shaped bundles and handing them out. "Firestorm Girl Standard Issue Gliders. You can't fly with them like you can with jet packs, but they're useful. Just pull on this line and they'll extend, allowing you to glide through the air."

"Ferb, Perry," said Phineas as he put on his glider pack, "I know what we're really going to do today! We're going to save both Tri-State Areas again!"

Ferb stared an affirmative. Perry, however, looked apprehensive in spite of his owner's enthusiasm.

"What's wrong, Perry?" asked Phineas as he noticed the lack of conviction from his pet - indeed, his friend.

Perry felt a hand on his shoulder. To his surprise, he turned to see Candace bent over him.

"I know," whispered Candace. "But at this point I think you'll have to let them come. You won't ever stop worrying about them, but they'll... they'll be fine." She cleared her throat.

Perry nodded and gave her a small smile. After all, he had seen for himself last time how skilled the boys could be when in a pinch.

"Right, troops," said Candace as she stood up straight. "We're going now."

"Good luck!" Baljeet called after the others. As usual, he'd be remaining at the base to supply them with information if they happened to need it. Just as Perry was about to leave the hideout, however, the secret agent turned around and tossed a small gadget to him.

Baljeet tried to catch the gadget, but it slipped through his fingers and landed in one of his big pockets instead. He had to rummage through the pocket to retrieve it. When he came up with it again, he recognized at once what it was.

"A spare camera to link up with your wrist communicator?" he guessed. "We will be able to contact each other with this, is that correct?"

Perry gave Baljeet a thumbs up, then hurried off after the others.


Perry is a fast writer, ha. We should reach where the game's storyline starts off in the next chapter.
