Meanwhile in Phineas' backyard, Perry rested peacefully on the grass underneath the giant tree. He was finally getting his day off and everything was going so.. Perfectly. Unfortunately he should've guessed it would've been interrupted soon as his watch began to beep. Perry looked down at it and scowled.

'Oh come on! Today of all days?', Perry asked himself before standing up and placing his hat on his head. He pressed a secret button in the tree and jumped down into the hidden tubing and slides into his hideout below the house. As he landed in his chair, Monogram was already on the screen, obviously panicked about something.

"Agent P! Good! We have a terrible emergency! As it turns out, your owner Phineas Flynn has met your nemesis Dr. Doofenshmirtz. Ordinarily we wouldn't care cause it's not like they'd ever really be able to interact much beyond that silly little inventing competition but Phineas has ACTUALLY gone to Dr. Doofenshmirtz's evil lair and is WILLINGLY going to spend the rest of the day with that evil man!", Monogram briefed him.

Perry's jaw dropped. Phineas? With his nemesis? Sudden flashbacks of Perry's trip to the other dimension began to take over the small monotreme's mind as he was thrown back into a frenzy of fear and panic.

"This could only mean two things as I'm sure you're aware! Either he remembered his adventures with Doof into that alternate universe and has turned to the dark side or Dr. Doofenshmirtz had discovered your host family and is holding Phineas hostage! You have to go find out what's going on and put a stop to all this! IF, by chance, Phineas does NOT know you're his pet AND a secret agent, we're all off the hook on it. But if he does... I think you already know the consequences.", he offered a weak shrug as he stared down at the shocked agent as Perry tried to calm down his hyperventilation and stress. "I'm sorry Agent P. But it's all we can do."

Perry gave a small nod before Monogram disappeared from view and he quickly ran over to his helicopter. He knew he'd have to be careful NOT to get caught this time and only prayed that this wasn't the last day he'd ever see Phineas again.

Back at the DEI, Phineas spun around in a chair a bit as the two tried to come up with ideas. Heinz sat on a couch opposite, nibbling on the end of a pencil as he looked down at a notepad with a few suggestions that had been scribbled over.

"I dunno, Dr. D...", Phineas started to say. "I'm drawing a weird blank today. Maybe we're just not really supposed to hang out like my friends and I do..."

"Mm...", Heinz sighed as he racked his brain. "There's gotta be something for us to do..."

The two sighed and sat in silence as they continued to try to think. Phineas paused for a minute, tapping his foot in the air slightly as he thought, when he noticed his reflection in the computer monitor's screen and inspiration struck.

"THAT'S IT!", he exclaimed jumping up into his seat as Heinz looked up. "Dr. Doofenshmirtz! I know what we're gonna do today!"

"Y'know, that kinda sounds like a catchphrase there..", Heinz noted more to himself than to the actual inventor who only got down.

"What if we built a ray that changes the color of your hair, eyes, or skin?", he asked. "Imagine how fun it could be walking around town with like... Purple skin with..uh with-with uh White polka dots and bright red eyes with crazy green and blue hair!", he said, feeling more and more excited by the idea.

"Hmm...", Heinz thought for a moment over the possible result of the situation of them going out looking like that. 'It would definitely attract attention but what if it failed and it stuck to us permanently? Doctors constantly checking to make sure we're not sick not to mention the freaking out his mother would do when he got home. But then again.. The empinator's working perfectly. His designs and his plans and heck Heinz. You even won just by helping! It's obvious the kid knows this stuff so let's try his inventions.'

"Okay.", he smiled. "Sounds like a good idea."

"Awesome!", Phineas sat back in the seat and whirled around to start drawing up the blueprints when he suddenly stopped and thought for a moment. "Hey.. I wonder what Candace is doing.."

"Who's Candace?", Heinz asked.

"My older sister. I hope she's doing okay."

Back at the party, Candace was busy talking with Jeremy when her phone began to ring.

"Oh! Sorry Jeremy. Mind if I...?", she asked, holding up her cell.

"Oh sure it's fine!", he nodded.

"Thanks.", she gave a quick nod and walked a bit off as she answered the call. "Hello?"

"Hi Honey.", Linda said on the other line. "Just wanted to let you know that Grandpa Fletcher is feeling better and we're gonna be heading home now. We should get there by dark. Are you having fun with your brother?"

"Oh yeah. Things are going just fine here.", Candace said. "Phineas and I are doing just fine."

"Okay. We'll be home in a few hours. Bye Candace."

"Bye Mom!", Candace smiled and shut off her phone.

She noticed the time on the front of her cell and thought about the trip back home. She walked up to Jeremy, explained her situation and then came up to Stacey and Coltrane.

"Hey Stace? I think we oughta go back and pick up Phineas. Mom's gonna be home in a few hours.", she explained.

"Oh that's cool. Right Coltrane?", she asked.

"Yeah it's alright with me. Let's get going.", Coltrane nodded and the trio headed out the door.

Once at the park, Candace looked about the closed down competition area for her little brother.

"Phineas?", she called out, finding no reply. "Phineas! Come on! It's time to head home!"

As she looked around, an odd feeling of fear settled on her mind.

"Phineas!", she called again, looking around faster. "Phineas if this is a joke or you made something to turn you invisible, IT'S NOT FUNNY!", still no answer as her panic grew more and more. "PHINEAS FLYNN YOU ARE SO BUSTED!"

Nothing. No one. There wasn't a single person left in the park. For once in Candace's life, she felt absolute fear in the realization that her brother was missing.

"AAAAAAAAAAAAAHHHHHHHH!"

Meanwhile, millions of light years out in space, in a large spaceship, Mitch the Alien paused for a moment, and looked over to his arch-nemesis, Meap who was trapped in a small glass cage.

"Do you hear something?", he asked, catching Candace's scream.

Meap only shrugged.

Back on Earth, Candace ran over to Stacey, explaining what the screaming was about.

"...and now he's lost and probably hurt and it's all my fault!", she panicked as tears came into her eyes.

"Well I don't wanna sound mean but I told you, you should've been nicer to him.", Stacey rolled her eyes.

"Stacey! I'm being serious! What if he was hurt or stolen?", Candace said before suddenly gasping as a look of terror and realization crossed her features. "What if the mysterious force that comes after Phineas' inventions, took HIM now?"

"Candace calm down! You probably just didn't look hard enough. I'm sure Phineas is still here. Let's look together.", Stacey said, hoping to calm her down as they began to search.

"Stacey.. I'm really worried about him..", Candace whimpered.

"I know. I'm sure it's all okay.", Stacey reassured, trying to convince herself as well.

Back at the DEI, Perry landed his hover car and quietly snuck into the room. He hid behind some crates as he looked over finding Phineas and Heinz bent over the blueprints. Perry tried hard to keep himself calm but he couldn't help but think that his heartbeat would blow his cover as it pounded in his ears.

'PLEASE don't let him be up to anything evil...', Perry silently prayed.

"So I was thinking that we'd have a fairly good choice of different colors to choose from.", Phineas was explaining. "Not very limited like a lot of 'create a character' games do but we don't necessarily have to go into shades."

"Well all I'm saying is we don't really HAVE to have pink, right?", Heinz asked. "I mean.. We're not perfectly pink colored. People are sort of a uh.. Something kinda like a very pale orange."

"Well that's where we feed our DNA into the machine here, see? It'll register our normal colors and we'd go back to the way we were because our skin's actually pretty closely related to our hair color.", Phineas said. "Or... Do you think that's too much and we should just have an undo button or something?"

"Mm.. No. I've done DNA stuff before. It's not really that much trouble.", he shrugged. "So it'll just basically give us a quick dye-fix and we could always go back to normal with our DNA, then?"

"Basically. I was thinking not so much of dye like hair-dye, cause that stuff could stain your skin, but something like... Like it basically changes your hue. Your body only captures specific light rays to portray you as something else."

Perry let out a long breath of relief. Phineas wasn't doing anything evil. He wasn't being subdued by Doofenshmirtz. He was just doing normal mediocre kid stuff like he does everyday. Perry thought for a moment about just going home and retelling it to Monogram but he couldn't help but feel like he oughta stick around just in case something went awry. He sighed and rolled his eyes.

'Like always..', he thought.
