I do not own Phineas and Ferb.
Where's Phineas and Ferb?
It took the platypus roughly five minutes to knock the stubborn scientist out of the air. The Lazy-Inator slammed to the pavement and mechanical pieces scattered in all directions. Heinz let out a grunt as he crashed onto the roof of someone's car. The alarm triggered, small beeps of warning echoing through the nearly-empty street.
Heinz rolled off of the car with a grimace and glanced down the sidewalk. He could see his brother's office a yard away. "So close and yet so far. Curse you Perry the Platypus!"
Perry grinned and tipped his hat to the exhausted evil doctor. He turned around and flew in the direction of Heinz's building. The boys had not joined up with him so he figured they were still trying to get themselves out of their bindings.
But when the platypus climbed through the open window, his boys were nowhere in sight. He frowned. I guess they're still searching for Doof and me.
Perry activated his hat propellers once more and flew over Danville, scanning every nook and cranny he passed. Eventually he caught sight of his nemesis limping down the street. He flew down and landed in front of Doofenshmirtz.
"Perry the Platypus?" Heinz asked in surprise. It was rare when the agent showed up twice in one day, so he instantly got the feeling that something was wrong. "What's the matter?"
Perry gave a concerned chatter. Heinz had known the platypus long enough to understand what he meant by that simple sound. "No, I haven't seen Phineas and Ferb. But they're probably still back at my place. Admittedly, I made the knots a little too tight. My bad."
Perry shook his head. Heinz tapped his chin. "Not at my place, huh? I didn't think it would be that easy. Do you want me to help you look?"
The members of L.O.V.E.M.U.F.F.I.N. would have fainted if they had heard Heinz make the offer. Helping your nemesis was unheard of, something you just didn't do.
But Heinz knew that the relationship he shared with his nemesis was different. He didn't mind helping the platypus when he needed it, and Perry didn't mind helping the doctor when he needed it. And Heinz certainly didn't want to leave Perry searching for the boys alone. He knew exactly how he would feel if Vanessa was missing, and he would want all the help he could get to find her.
Perry shook his head again but smiled appreciatively as he did so. Thanks for the offer, but I'm sure they're around somewhere. I'll keep looking.
"If you say so. But if you need any help, give me a ring."
Perry saluted Heinz and flew back into the air, resuming his search. Heinz watched the platypus for a moment before frowning. "I hope the feeling I have in my stomach right now is a cause of the Mexican food I had last night and not a prophetic feeling."
...
When Major Francis Monogram didn't get a report from Perry by late afternoon, he grew concerned. "Carl, contact Agent P. He should have reported back to us hours ago."
"Yes sir." Carl slipped on a pair of headphones and was about to call Agent P when a beep from the communications console signified a request for a video conference. "Well, talk about timing. The call is from Agent P's lair."
"Oh, good." Francis let out a sigh of relief and stood in front of the video camera. Carl connected their main network to Perry's computer and brought up the platypus' image on the monitor. "Agent P, I was starting to wonder what had-Agent P?"
The agent had a look of such fear that it caught Francis off guard. Perry started to chatter wildly, distress evident in his tone. As Francis tried to figure out why his best agent was so upset, Carl carefully got up from his position at the console and went to his personal laptop. There was really only one thing that would cause Agent P such distress and that was the lives of his family being in jeopardy.
The intern tried to track the location of Phineas and Ferb and was disturbed when his computer stated that the signals were out of the area.
'Out of the area' meant that the Flynn-Fletcher duo were no longer on planet Earth.
"Not good," Carl muttered nervously. He cleared his throat, catching the attention of his boss and Agent P. "I just tried to track the location of Phineas and Ferb using their bracelets, but the computer told me that they were out of the area."
Francis was stunned. "But that means-"
"Not on Earth," Carl finished. "Yeah."
Agent P struggled to remain calm, but panic was threatening to overtake him. If my boys aren't on Earth, then where are they? Who has them?
In order to find answers to these questions, he was going to have to relax a bit. Perry took a deep breath. Phineas and Ferb had to have been kidnapped on their way to meet me. If there are any clues as to their whereabouts, they'll probably be between Doofenshmirtz's building and the mayor's office.
Perry gave a sudden chatter of determination and jumped from his seat. His superior studied him thoughtfully. "Are you going to look for evidence?"
Perry nodded, grateful that his boss had the unique ability of understanding his animal agents (for the most part anyway).
"Would you like me to contact the kids to help you search?"
Perry thought for a moment before shaking his head. He didn't want to worry anyone, at least not until he knew exactly what had happened to his boys.
"Then I'll leave it to you to notify them. But if you find anything, anything at all, let us know right away," Francis instructed.
The semiaquatic mammal saluted him before departing his lair.
The sooner he found where Phineas and Ferb were, the faster he could rescue them.
...
Despite the platypus wanting to keep the others in the dark, they had a feeling something was wrong. Isabella, Buford and Baljeet grew worried when the brothers did not join them in their backyard by late afternoon. "They never take this long to defeat Dr. Doofenshmirtz," Isabella said with a frown. "Where are they?"
"Perhaps they stopped for some ice-cream," Baljeet suggested.
The Mexican-Jewish girl shook her head. "They would have called and let us know that they would be late. Something's wrong, I can feel it."
"Then let's stop sitting around and go look for the dweebs," Buford snapped, getting to his feet.
"Or," Baljeet said quickly before Isabella could yell at the burly boy for calling Phineas a dweeb. "We can call Carl and ask if he knows where they are."
"That's a good idea," Isabella said. Buford scowled and crossed his arms as the girl used her bracelet to contact the intern. "Carl? Are you there?"
"Hey, Isabella. What's up?"
"Phineas, Ferb and Perry haven't shown up yet. Do you know where they are?"
"N-no, I c-can't say I do," Carl answered nervously.
Isabella narrowed her eyes at the sudden change in the intern's voice. "You know something!" she accused. "Something you're not telling us!"
"I know nothing, I swear!" Carl cried.
"Don't make me come down there," Isabella threatened.
"She is not kidding," Baljeet warned.
"Unless you want Isabella to come down there and knock you one, ya better tell us what happened to Phineas and Ferb," Buford growled.
"...I guess you could say that's the problem," Carl finally responded. "I don't know what happened to Phineas and Ferb."
"Can you not track their bracelets?" Baljeet asked in confusion.
"Well...the thing is..." Carl hesitated. He knew Perry didn't want him to tell anyone of the disappearance of the brothers but he knew that no matter what, the kids would find out what happened to them on their own accord. "The computer says that Phineas and Ferb are no longer on Earth."
"How is that possible?" Isabella exclaimed.
"That's what Agent P is finding out."
"Then we're gonna help him," Isabella said determinedly. "I'll round up the girls and-"
"NO!" Carl shouted, the speakers buzzing from his loud outburst. "We have no idea what we're dealing with. For all we know, it could be something dangerous. You kids will-"
"Go at it alone," Isabella finished firmly. "And we won't risk putting anyone else in danger or worrying them."
"You can't-!"
"We can," Buford countered. "And you're not gonna stop us."
"If anyone can figure out what happened to Phineas and Ferb, it's us," Isabella said. "After everything we've been through together, we can handle something like this."
"Do not worry," Baljeet assured Carl. "We will be fine...most likely."
Isabella turned the bracelet off before Carl could protest. "Come on, boys. We're going on an investigation."
