Phineas and Ferb: Across the Second Dimension WHATIF

“Now I have you!”

Perry wheeled around at the triumphant cry unleashed by the alternate dimension version of his incompetent nemesis.

Phineas was in trouble. The evil Doctor Doofenshmirtz had gotten a hold of the boy’s baseball launcher and had it aimed at Perry’s owner, backing the boy up towards the edge of the Other Dimensioninator’s platform.

The playpus didn’t know what to do. If he leapt up there, the Doctor might fire and Phineas would go tumbling over the edge. The secret agent had been up there. He knew full damn well that the Other Dimensioninator’s platform hovered over the edge of the Doofenshmirtz Evil Incorporated skyscraper. If Phineas fell, there was no way he could get to the boy in time to save his life.

“All you’ve accomplished here is that I’m going to have a new Platyborg, maybe a new Boyborg too.” The evil doctor was crowing as Phineas got too close to the edge for Perry’s liking.

Why oh why had he brought the boy up here? He could have handled it alone, the secret agent lied to himself as he tried to work out a way to save his beloved friend and owner.

Then it hit him as his tail brushed against the baseball bat Phineas had happened to leave there when they’d been there hours ago, before they’d been trapped in the second dimension. If he could get that baseball bat to Phineas, the boy could hit the baseball away and defend himself.

Perry only had a split second to act as the doctor went to fire. He moved, trying to knock the bat flying, only to get hit by a blast from Perry the Platyborg’s laser cannon that sent him flying into the Other Dimensioninator, breaking the control panel and sending the machine out of control.

The second dimension Doofenshmirtz had already hit the trigger on the baseball launcher before he had actually reacted to the flying platypus, and the high speed baseball hit Phineas in the stomach, causing the boy to let out a pained yelp and stumble back, before letting out a second, much more terrified cry as he stumbled right over the edge.

Perry chittered in fear as he launched himself past the evil Doof, ignoring the complaints of how and why and ‘this isn’t possible’ that were erupting from the man as the machine started to explode, in favour of trying to save his owner. He leapt off of the platform, following his owner down, figuring that if he could get close enough his grappling hook might save them both.  

What he saw next shocked him. Ferb, who had been climbing up the side of the building using a pair of plungers, had grabbed onto Phineas’s arm as his step-brother had gone plummeting past, holding on desperately to Phineas with one arm and a plunger with the other even as he cried with the pain and stress of the situation and the weight of his step-brother.

The platypus’s heart skipped a beat when he realised that the plunger that Ferb was hanging off of was pulling away from the window.

He wasn’t the only one who saw it either, Phineas, who was already pale with the fear and shock had gone whiter still when he had realised that Ferb was going to fall if he didn’t get the green haired boy to let go.

Perry never heard the words that passed between the boys, only saw Ferb shaking his head and caught the pleading look on Phineas’s face.

Then, to Perry’s horror, Phineas gave his brother a reassuring smile and wrenched his arm from Ferb’s grasp. Ferb cried out in fear for his brother as Phineas continued his freefall to the ground.

Just moments later, as if mocking Phineas’s sacrifice, the suction cup on the plunger Ferb was clinging to released its hold on the window.

Perry couldn’t save Phineas, but he was damned if he was going to lose Ferb too. He managed to get close enough to Ferb to grab onto the boy and fired off his grappling hook, which swung him and Ferb over to the nearest building, dropping them both on its roof.

“PHINEAS!” Ferb practically screamed, darting for the roof edge, with more emotion in his voice than Perry thought he’d ever heard from the normally mute one of the pair.

Perry wasn’t sure he could bring himself to look.

He knew what he’d see. Phineas wouldn’t have survived the fall. He’d have hit the ground and...

The platypus let out a grieved wail of a sound, giving into the pain he felt at losing one of the boys, and suddenly found himself scooped up into a pair of shaking arms and drawn into a rough hug, water dripping onto his head as his owner wept and sank to his knees.

Phineas was gone. Phineas was...

“Ferb? Perry?”

Perry froze at the sound and felt his remaining owner tense up too. It wasn’t possible...

“Hey guys? We still have things to do today...”

Ferb practically exploded from the spot, pushing Perry away and tackling the speaker in a hug that knocked both of them over.  “H...How?”

Perry already knew though and even as Phineas tried to sit up to explain, Isabella dismounted from the flying robotic unicorn that Phineas and Ferb had made her at the start of the summer and rushed over to hug both boys.

“Guess those old inventions of ours had more than one use left in them.” Phineas commented in a much softer tone than normal, hugging both carefully, mindful of the shoulder Ferb had practically wrenched out of place when he’d tried to save him from certain death and of any injuries Isabella might have gained during the fighting. “Perry?” Phineas invited him into the group.

As he leapt into the pile and joined the group hug, Perry thought of all the trouble he and the agency had gone to to locate, recover and reproduce all of the things the boys had invented over the summer and couldn’t help but think that it was totally worth it.
