Yes, the prologue takes place during "The Phineas and Ferb Effect." But the rest of this fanfic takes place after Season 2. Oh, and Conspiracy Theorist Dakota is my Lost Dakota OC.

Chapter 1: Home Sweet Home

As Milo Murphy awoke from a particularly heavy slumber, the first thing he noticed was that a tree had crashed through his bedroom window.

"Man, it is good to be home!" Milo said to no one in particular.

One hour later, Milo finally stumbled out of his bedroom, fully dressed and backpack securely strapped to his back.

Walking down the stairs, Milo had just reached the bottom step when the doorbell rang.

"Milo, honey? Could you get that?" Brigette called from the kitchen.

"Sure thing, Mom!"

Milo opened the front door, then stared at it in amazement. "Nothing fell apart? What gives?" Then he spotted his two visitors.

"Phineas and Ferb!" Milo cried.

"Hey, Milo," Phineas said with his usual grin. Ferb greeted Milo with a thumbs up.

"I wasn't expecting you guys," Milo said.

"You did say we could cross over any time," Phineas pointed out.

"Well, that's true," Milo laughed. "Did you want to come in?"

"Sorry, but we can't stay," Phineas said. "We just came by to invite you to the docks this afternoon. Ferb and I have been working on a project that we really want to show you."

"That would be great, guys," Milo said. "Hey, can I bring a few friends? I was supposed to hang out with Zack and Melissa today, but we didn't have any plans."

"Of course! The more the merrier!" Phineas agreed. "If anyone else you know is free, you're welcome to invite them too."

"Gee, thanks!" Milo said.

"See you later, Milo!" Phineas waved as the brothers ran off. "Come on Ferb, we've still have the preliminary tests to finish."

Milo shook his head. "Those two are great," he chuckled. As Milo turned to go back into the house, the front door fell off its hinges. "There it is!"

"I cannot believe that Bob Block fired you in addition to me," Cavendish complained as he paced around the rented office. "I'm the one that went rogue! You're the one that continued to do your job properly."

"I can't believe that Bob Block yelled at us," Dakota said through a mouthful of a Slushy Dawg corndog. "I didn't think he could get angry! Now we know where his great-great-great grandson gets his temper."

Just then, someone knocked at the front door. It was a musical knock that sounded like dundundun dundundun DUNDUNDUNDUN.

"Oh, that's probably Dr. D.," Dakota said.

"How can you possibly know that?" Cavendish asked.

"I spent a few weeks with the guy while you were going rogue," Dakota pointed out as he walked over to the door. "Dr. D. loves to talk. And sing. He sang the jingle for his old business at least a dozen times since we started hanging out. That's what the music from that knock was," Dakota explained as he opened the door to reveal Dr. Doofenshmirtz and Cavenpuss. "Ta da!" Dakota added.

"Hey Cavendish, Dakota," Dr. Doofenshmirtz waved, letting himself and the human-platypus hybrid in. "Oh, and just for the record, I only sang the "Doofenshmritz Evil Incorporated" jingle five times."

"That's still way too many times," Dakota argued.

"I don't even know that jingle, and I agree that singing it five times is too much," Cavenpuss said.

"So!" Cavendish spoke up. "What can we do for you, Dr. Doofenshmirtz?"

"Oh yeah," Doof suddenly remembered why he was there. "So, I'm not sure what to do with Abomination here," he gestured toward Cavenpuss, who had pulled a live snail out of nowhere and was munching on it. "So I'm giving him to you guys!"

"What?" Cavendish cried.

"Why us?" Dakota asked.

"Well, I'm busy trying to become Professor Time, plus Cavenpuss and Cavendish are

practically brothers," Doof argued.

"But we're busy trying to find new jobs, and you cloned the hybrid, so you are practically Cavenpuss's father!" Cavendish shot back.

"Wait a moment," Cavenpuss interjected. "I thought we were here to get my baby back!"

That made the three men stop arguing.

"Your baby?" Dakota arched an eyebrow.

"Cavenpuss laid an egg while we were in that Octalian spaceship," Doof explained. "He

was all weirded out at first, but now he insists that he has "maternal instincts" and wants the egg back. We need help getting back to the ship."

"So why didn't you go to Milo? He knows where the ship is too, plus you've been living with him for months," Cavendish pointed out.

"And you were both with us when we landed that ship," Dakota added. "You know where it is."

"Eh, Milo was sleeping in this morning," Doof said. "Besides, I don't really like being in the Danville Woods alone. Too many racoons."

"So you want us for protection?" Dakota asked.

"Yep," Doof said.

"Fine," Cavendish sighed. "But we also need to figure out Cavenpuss's living arrangements."

"Weird how when we landed the spaceship, it landed in the same spot as we originally found it, huh?" Dakota pointed out as walked inside.

"Quite," Cavendish agreed.

"Okay, so where's the egg?" Doof asked.

"Ah! There he is," Cavenpuss crawled underneath the control panel and picked up his still unhatched egg. "Did you miss daddy? Yes you did, didn't you?" the hybrid whispered, stroking the egg. "Shh, shh, daddy's here, daddy's here."

"All right, we've gotten the egg, now let's go," Cavendish joined Cavenpuss at the controls. Just then, one section of the panel started beeping.

"Okay, for the record, I did not touch anything," Doof said.

"Me neither," Dakota added.

"Don't get your knickers in a twist, gentlemen!" Cavendish puffed out his chest. "I have partially decoded the alien language used by the Octalians…"

"And you'll never let us hear the end of it," Dakota muttered. Doof laughed loudly.

"Ignoring that," Cavendish said. "For you see, I can read the labels of this particular section." Squinting at the label of the beeping doodad, he continued, "It says "Negative Probability Ion detector."

"Wait, doesn't that have to do with Murphy's Law?" Dakota pointed out. "Why would it react to you?"

"Maybe Cavendish is also surrounded by negative probability ions," Doof suggested.

"Hey Cavendish, Dakota, Dr. D.," Milo biked up to the entrance of the ship. Zack and Melissa followed on their bicycles.

"Or maybe Murphy is just nearby," Dakota said.

"Hey, if you guys are done here, do you want to come with us?" Milo invited. "We're going to the docks to meet Phineas and Ferb."

"Sure, why not?" Doof agreed.

"I suppose so," Cavendish said.

"I'm in! Those guys are cool," Dakota grinned.

"Count me out," Cavenpuss said. "I should go somewhere I can keep an eye on my baby."

"Aw, of course, Cavenpuss," Melissa agreed.

"Yeah, we can swing past Cavendish and Dakota's place on the way. It's closer than Milo's house," Zack suggested.

"And much safer," Cavenpuss added.

As the group filed out of the alien ship, Milo added. "Let's get going. I can't wait to see Phineas and Ferb's new project!"
