* So I've decided to try my hand at a Phineas and Ferb story. You could think of it as a missing or kidnapped character story. I made a reference to the seond verse of the Phineas and Ferb theme song. I also made a reference to 'Summer Belongs To You'. I don't own Phineas and Ferb. I don't own Phineas and Ferb The Movie: Across The Second Dimension. I don't own the song 'Today Is Gonna Be a Great Day'. I don't own 'Summer Belongs To You'. Any constructive criticism you have would be great.

Companion story to "Back To Normal".

Prologue

It's come to my attention that the universe has it out for me. First, it's nearly exposed me several times. Second, when my secret was finally revealed, everyone got there minds wiped anyway. And third, all of that hassle was made by a lost choo-choo train in the VHS section of a drawer.

The best day of my life was when I showed Phineas and Ferb I was a secret agent, there was even a plan to tell them after there memories were gone. It was a "should've, could've, would've" moment that I missed.

That was a mistake, a big one. If I told them a long time ago, I wouldn't have put them in danger in the other dimension, or if I told them a few nights back…

They might not have been dumped into this mess…

Chapter 1

"Morning, boys," Linda said as she walked out into the backyard. As always, under the tree sat Phineas, Ferb, and their pet platypus, Perry. Blank blueprints and scraps of paper lay strewn about at their feet. "Your father and I are going to the Antique Shop early. What are you up to today?"

Phineas smiled. "Ferb and I were just about to…" He paused. "Well, we were planning on building…maybe spend the day doing…" Phineas looked to his brother. "What were we going to do today?"

The silent of the two looked thoughtful for moment, and then shrugged.

"Huh," The red-head mused. "I guess we forgot."

"Well," The mom grinned as she slung her purse higher on her shoulder. "I'm sure you two will figure it out eventually." She looked back as she started to pass through the gate. "Remember, your sister is in charge."

As Linda hopped into the car, Candace raced out of the house.

"So," She drawled out the word. "By 'in charge', you mean-"

"Candace, if a satellite crashes into the house or if a herd of wild moose invade the living room, you're in charge." The parent shut the car door and rolled out of the driveway.

The teen happily zoomed back indoors and made a grab for the telephone. The conversation between her and Jeremy went on for a while. It was long enough that, surprisingly, she never seemed to be bothered by what her brothers were up to.

Phineas sighed. "I could've sworn we had a plan today Ferb." He drew random shapes and patterns on a sheet of graphing paper, trying to jog his memory. "Hmm, well, we could go see what everyone else is up to – oh wait, that's right." He was reminded that all of their friends were unavailable.

Baljeet was with his family visiting Uncle Sabu at the rubber bands and balls factory, Buford was having a personal day with his goldfish, and Isabella was away on a trip with the rest of the Fireside girls.

Phineas glanced down at the sleeping platypus. "What do you want to do today, Perry?" Without opening his eyes, he chattered and went back to his light snoring.

Ferb suddenly reached behind him and drew out the book listing all of what they did that summer.

Phineas flipped through the pages with an eyebrow raised. "Yeah, I suppose we could redo one of our old inventions, but it's not a new idea. If only we could remember what we wanted to do earlier…" The light bulb immediately lit up in his head.

"Ferb, I know what we're going to do today! You make a run to Blueprint Heaven while I find all the note paper we have."

"Devising a system for remembering everything?" Ferb asked.

"Let's get started." Phineas' smile disappeared as his gaze did a loop around the yard. "Hey, where's Perry?"

Unknown to them, the semi-aquatic mammal ran off minutes ago. Perry never heard what they were planning on doing.

Soon, the backyard, the tree, and fences were covered in sticky notes. Phineas was leaning over an easel as Ferb ran over to him, the blueprints in hand.

"Okay," The red-head turned around to face his brother. "All of these notes have our memories on them. The knowledge spans from our first words to our inventions, from the day we made the rollercoaster as well as all of the songs we ever sang. Nearly everything we know is written down."

"These are things we already know, though." Ferb remarked as he rolled the blueprints out on the grass.

"That's where we modify it." The step-brothers sat next to each other. "We'll load the gadget with all of this information along with adding a memory jogger configuration into the hardware." Phineas looked over plans with confusion. "It's a little different from the picture online. I wonder what the remote is supposed to do."

(Minutes later)

"Okay," Phineas said as Ferb screwed in the final piece. "It doesn't look anything like the picture." They stood back to look at their…well, they weren't quite sure what it was.

The device was certainly odd. It was a tall metal structure with two purple rings attached: one looped around the base and the other held the lever that appeared to activate it. It also seemed to have what looked like a giant spoon mounted on the top.

"Is it me, or does it seem like we've built this before?"

Ferb shrugged and walked forward.

He was about to turn it on before Phineas suddenly piped up. "Something doesn't feel right, like we shouldn't have made this in the first place." His eyes nervously scanned over the gray, metallic texture.

Ferb felt the same way. The whole situation was eerily familiar, but he didn't hear a disagreement. Pocketing the remote, the mechanically inclined kid pulled down on the switch.
