I want to thank all the people who reviewed for their nice reviews. One of the reasons I wrote this story is I've noticed a lack of stories focusing on the 2nd Dimension characters, or even them interacting with the main ones, even though it's pretty much a blank slate. Okay, yes the movie did reveal some of the characters, but there's no official 2nd Dimension versions of Carl, Stacy, Irving, etc. and that should give writers free reign to use them as they wish. I'm just putting that out there.

Phineas struggled against the ropes that held him to the chair, but to no avail. Still he continued, knowing he had find a way to get loose.

Hmm, if I can rock the chair hard enough, it should fall over and break, he thought.

So he began rocking back and forth as hard as his little body would let him. Eventually, he felt the chair wobble and it began to fall to the ground. But it didn't break, and all Phineas achieved was making his head hurt.

Okay, that didn't work like I planned, he thought all I can do now is wait for Ferb to come find me. Except he doesn't know where I am, no one does. Oh man, now that evil guy is going to stop me from being born and there's nothing I can do about it! It would take a miracle to save me now.

Just then, Phineas heard a "whooshing" noise. He turned his head, from where he was currently positioned on the floor, and noticed a green shimmering portal.

"That'll work."

Moments later, a familiar face emerged from the portal.

"Other me!" Phineas exclaimed happily.

"Hold on, I'll have you out of there in a jiffy," Phineas 2 said, rushing over and pulling the chair back up. He then quickly untied Phineas, and embraced his counterpart.

"Boy am I glad to see you," Phineas said "or, in this case, me. How'd you know where to find me?"

"We were able to detect a portal made by Doof's Other Dimension-inator," Phineas 2 explained "so we just followed the trail right to this location."

"Wait, we?"

After Phineas said that, two other figures emerged from the portal.

"Hey other Ferb, other Candace," Phineas greeted them.

"Nice to see you again Phineas," Candace 2 replied "although I wish we could've reunited under better circumstances. Is Doof still here?"

"No, he took the time machine and left," Phineas explained "he's planning on going back in time and making sure I was never born."

"That's not going to happen," Candace 2 assured him "but if we're going to stop him, we'll need a time machine of our own, and time is of the essence."

"We could borrow the one down at the museum," Phineas suggested "I don't think they'd mind."

"Then let's get the lead out," Candace 2 "Doofenshmirtz already has a head start and we need to catch up."

"Do you think I could get Ferb first?" Phineas asked "I know he's probably worried about me, and I could really use his help on this one."

"I suppose so," Candace 2 replied "but make it quick."

A little later, back at the Fletcher-Flynn house, Isabella was getting worried.

"Okay, this is way too long for Phineas to be in the bathroom," she told Ferb "I'm going inside and see if I can't find him. You wait here in case he comes back."

Ferb nodded and watched the girl go inside. Then he got up and wandered around the yard, trying to find any sign of his brother. As he approached the fence, he heard a familiar whisper.

"Ferb, psst, it's me."

Ferb looked and saw Phineas behind the fence. He ran over and hugged him.

"I'm glad to see you too Ferb," he said replied "look, I'll explain everything later, but you have to come with me right now, okay?"

Ferb nodded and followed his brother down the road.

Meanwhile, in the house, Isabella was looking for Phineas, when she spotted Candace texting on her phone in the dining room.

"Candace, have you seen Phineas?"

"Aren't they outside working on something?" she asked "I was going to bust them, but I didn't hear them making anything, so I figured they gave up."

"Oh no, they finished their project," Isabella explained "but then, Phineas said he was going to come over to my house and he never showed up."

"I'm sure he's somewhere in the backyard," Candace "come on."

Candace opened the sliding door and stepped outside "okay Phineas, show yourself" she said "seriously, this isn't funny! Come out now, or you're so busted!"

"Hey, where's Ferb?" Isabella asked.

"Ferb's missing too?" Candace asked, shocked.

"Well he was here," Isabella explained "I asked him to wait outside while I went in to look for Phineas. Where could he have gone?"

"Was my brothers' project for today, by any chance, invisibility suits?"

"Nope, they made shoes that can stick to any surface."

"Wow, that's actually…pretty normal," Candace said "and you're sure both of them were here this morning?"

"Yes!"

"Hmm, let's see, my brothers were working on a project, then they just disappeared," Candace mused "and I didn't…that's it!"

"What?"

"You know how every day something takes my brothers' inventions away before my mom sees it?"

"No, but go on."

"Today, I didn't hear Phineas & Ferb making a lot of noise, so I didn't try to bust them. So, since I didn't try to show their invention to my mom, this thing, let's call it a 'mysterious force' made my brothers disappear instead!"

"That makes absolutely no sense!" Isabella told her.

"I have to appeal to the force and get it to return my brothers!" Candace said, ignoring her and running off.

"Well, she's obviously going to be no help," Isabella commented.

Just then, Buford & Baljeet arrived in the backyard.

"Hello Isabella, where are Phineas & Ferb?" Baljeet asked.

"Yeah, Dinner Bell told me he was making some special shoes that could walk on all kinds of stuff," Buford said "I wanted to take 'em down to the beach and freak people out by walking on the water."

"Sorry guys, but there's been an emergency," Isabella explained "Phineas & Ferb are gone."

"Gone?" Baljeet asked "what do you mean?"

"And what's up with her?" Buford asked, pointing to Candace, who was running around the backyard, waving her arms frantically.

"She's finally lost it," Isabella explained "and when I said gone, I mean disappeared, vanished, took a powder, not here. I can't find them anywhere and I'm really worried."

"So, does this mean we don't get to try out the shoes?" Buford asked.

"Not until we find them," Isabella said "we'll split up; I'll go down Maple drive and head downtown. Baljeet, you take the left side of town, Buford, the right. Now let's move people!"

"You guys go ahead, I gotta do something first," Buford said.

After the other two left, Buford went into the backyard and took one of the pairs of multi-purpose shoes that were still under the tree.

"Heh heh, these babies are gonna come in real handy."

Unknown to their friends, the real Phineas & Ferb were heading downtown to the museum along with their 2nd Dimension counterparts and the counterpart of Candace.

"So, how come you guys are still wearing resistance gear?" Phineas asked "I thought your dimension was free of Dr. D's rule."

"It was, for a while," Candace 2 replied "but then he regained power."

"How?"

"That's a story for another day," Candace 2 told him.

"Sooo, are you going to tell it to us?" Phineas asked.

"Maybe after we catch up to Doof, if there's time," she said.

Soon they reached the museum; since it was still mid-day, they were able to get in with ease and made their way to the time machine.

"There she is," Phineas said proudly "it's weird no one in this museum knows this thing actually works. Think how much money they could make."

"Let's move," Candace 2 ordered "we don't have much time."

Everyone hopped in, then Phineas activated the controls, and the time machine vanished from its' display.

Next time, the gang arrives in the past, and Phineas learns how Doofenshmirtz 2 regained power in the Tri-State Area.
