Hey, I know a couple people were interested in seeing a sequel to my other Phineas and Ferb fan-fic up. I just wanted to mention that this is not it. I'm not sure if I'm going to write one because I'm generally not that great at sequels, (my personal opinion… ) so instead I'm writing some of the other ideas I've gotten from the show. Please enjoy, anyway.(Although, I doubt it not being a sequel is going to be that big of a deal… )

Chapter One

The two sat under the shade of a great tree. Most would find it quite relaxing, but to them it was a place of planning. Not to say that they didn't find it relaxing as well. After all, they did just relax there at least once or twice, but now wasn't one of those times.

Instead, one was busy explaining away what the two would possibly be doing that day with his usual bright smile across his face while the other just listened thoughtfully.

"…and Perry can even help, too," he added as they both glanced over at the inactive lump beside them. It gave its usual chitterling noise and the boy gave the platypus a slight pet.

A few seconds later a young girl walked into the backyard, although her focus was on one boy more than the other. In fact, as soon as she was close enough she said, "Hi Phineas," and then added sweetly, "Whatcha doin'?"

He smiled up at her. "Oh, hi Isabella. Me and Ferb are planning to travel to a different dimension."

"Isn't that kinda impossible?" she asked slightly confused.

"Actually, Ferb just took part of the design we used for Balgeet's portal to Mars and made it portable so we can get back," he explained as Ferb pulled something that looked slightly like a cell phone attached to a remote from behind his back. "I mean, think of all the places we could go; underwater cities, alien planets, places with millions of butterflies and eternal sunsets…"

She sighed as she though about the last two with just her and Phineas… and then quickly snapped back to the present. "That's so cool… Can I come, too?"

Phineas shrugged. "I don't see why not."

Inside the house, a teen was currently on her cell phone.

"…I know, it's gonna be so awesome! I can't wait…" she stopped and stared out the window pointing to the backyard.

"Sorry, I'm going to have to call you back…" she said before hanging up and heading downstairs.

"Alright, Ferb, fire it up!" Phineas said as Ferb started pressing buttons.

Suddenly, their teenage sister stomped into the yard. "You better not be planning anything today…"

Phineas glanced at her and tried to say, "Well, actually…"

"…because I'm going to a party later, and if you are, you're still so…"

"…busted…" she finished as the backyard also finished completely changing. There was still a tree, but sitting under it were two different boys and the house was now purple with a green roof and yellow polka-dots all over.

She blinked a couple times and then asked, "What did you just do?!'

"Well, I was trying to tell you, we're traveling through alternate dimensions today," Phineas explained.

"Oh, you two are so BUSTED!" she shouted, and then after realizing they weren't exactly home added, "…as soon as we get back home…"

"That might be a slight problem…"

"What do you mean 'slight problem'?"

"The batteries in the portable dimensional portal are drained," Phineas explained as Ferb held it up to show that there was a blinking symbol on it that looked a lot like a low battery light.

"You mean we're stuck here?!"

"No; we modified the batteries to run on happiness. There's no way they could run out that fast… unless…"

"Unless?" she asked slightly worried about the answer.

"…Unless we went from our home dimension where tons of people are happy to some drab and boring dimension where almost nobody's happy."

"…Great…" she moaned. "Can't you two just fix it?"

Phineas and Ferb shared a glance. "We are just kids," Ferb chipped in, "We can't exactly do it on our own."

"Hey, those two are probably the you of this dimension," Isabella pointed out as she motioned to the two other boys in the backyard. "Maybe they can help."

"That's a great idea, Isabella!"

They all took a couple hesitant steps towards the tree before Phineas greeted the two with, "Hi, I'm Phineas and this is Ferb…"

"Who cares?" one interrupted.

"What?"

"Who cares?" he repeated, then shifted and yawned as if that was the extent of his energy.

"Well, who are you, then? Isabella asked.

"I'm Phil and this is my brother Fernando," the boy explained as his brother sighed. "…he doesn't talk…"

"Very much?" Isabella guessed.

"No. At all."

A hard silence followed as all further conversation died right there. Everyone looked around nervously… except for Phil, that is, who just continued staring blankly in front of himself.

Suddenly, almost as if out of nowhere Phineas had a revelation. "Hey, where's Perry?"

Isabella glanced at him. "Well… was he with us when we came?"
