There's not very long until graduation
When adulthood comes upon us…
So the final hurdle of our generation
Is to find a way to jump the bus…
Like maybe?

Hunting a flash drive or duelling with the mother
Or strolling down the Champs-Elysees?
Discovering something completely unexpected
Or simply being remarkably blasé?

Surfing the computer waves, saving the school
Or collecting a sash full of patches?
Ducking and rolling, saving the continent
Or driving our father-in-law to matches?

As you can tell, there's a whole load of stuff to do
Before adulthood starts this June
So stick with us 'cause Phineas and Isabella
Are going to see it through!
So stick with us 'cause Ferb and Vanessa
Are going to follow through!

"Granny! Uncle Phineas and Ferb are singing something funny!"

Phineas unwrapped the package. After who knows how long, the Fireside Girls had finally got a uniform for older boys. Isabella herself had to get this started. Phineas was still the only boy in the entire troop, but that didn't matter. The uniform consisted of a brown cap instead of an orange one, along with a brown pair of shorts. He also found a replacement orange and white-striped sash, seeing as his last one was all full. After putting this on, he went downstairs for breakfast.

"Morning Phineas. Isabella called, there's an important Fireside meeting today. Remember, school comes back tomorrow," Linda told him. Phineas nodded his understanding, and Ferb nearly choked on his cereal. Phineas finished his breakfast quickly, and rushed over to the Fireside Lodge.

Isabella and Vanessa went for breakfast about ten minutes earlier. Isabella had received an email from Gretchen, telling her that there was something urgent for the Fireside Troop, and she needed to call a meeting. Isabella had a faint clue as to what it was, and hurried to call Linda. Since Perry stopped waking up as early as he used to, Phineas had slept in a little more. Because she knew that Phineas disliked being woken up by things other than Perry, she refrained from calling him.

Once both Phineas and Isabella were gone, Ferb and Vanessa both knew what to do. They grabbed their pets, and jumped down a flower pot in their house. They emerged in the same lair, and went over to Major Monogram's image. "Morning, Agent F, Agent V. Doofenshmirtz has been working on a 'Destructinator'. Because this is a L.O.S.T.B.U.L.L.E.T. plan, I need you to finish this as fast as possible," he told them. They saluted with their free hand, and rushed Perry and Pinky out the tube. "You know Carl… we should really think about retiring both Agent Ps," he told Carl. "Sir… I think you're right. This should be their last mission. We don't have time or resources to call this mission off," Carl replied.

Phineas and Isabella were the last to arrive at the lodge. "Chief, Phineas," Gretchen said. "You are very nearly late." Phineas and Isabella apologised, and took their places. "Anyway. As you know, seeing as it wasn't that long ago when we enforced this rule, Fireside Troop members have an upper age limit. We need to get more new recruits! Melissa is the only Fireside Troop member who won't be leaving this June," Gretchen announced. Out of all nine of the Fireside Troop members at present, it was shocking none of them remembered much sooner. Phineas silently cursed. He should have expected this. Candace was sacked not very long ago. All eight of the older ones were next. "Girls, I know what we're gonna do today!" Phineas called. Isabella smiled very briefly: the first time he said that, everyone fell over giggling. Especially since Ferb started vanishing with Perry, it was always a relief to know Phineas cared about the Fireside Troop as much as his step-brother.

"Anyway, girls. We don't have a week to spare before we're all sacked. Find a girl with the potential to become a Fireside Girl, and help her grab fifty patches. If Candace could do it… why can't we?" Phineas exclaimed. All of the Fireside Girls cheered, and rushed to find their replacements. Isabella only left as a token. Once no one was looking, she slipped back into the lodge, and found the rulebook. She found the rule that was causing all this drama. 'All Fireside Girls must be of school age to attend official duties'. She sighed, and took out the quill.

'All Fireside Girls must be of school age to be officially recognised as such. Patch-collecting is exempted.'

Isabella quickly rushed out before the others caught on.

"Ah, the Plateam! How unusual for you to come. And by unusual, I mean COMPLETELY USUAL!" Dr Doofenshmirtz told them. Since losing Vanessa, he had become much more mentally unstable. Perry was worried that he might follow on behind Dictator Doofenshmirtz someday. "Anyway, Roger always got away with destroying my evil schemes, just like he did with my stuff as a child. So now… THE DESTRUCTINATOR! I'll destroy his pathetic government house, hopefully with him in it!" Vanessa gasped, and tried to escape. Ferb simply looked around for something he could use to channel Phineas' ingenuity. Why did it have to be him who discovered Perry?

He found a small nail, which he used to break out of the trap. He released Vanessa, and they released the two pets. "Wha… Ferb Fletcher?" Doofenshmirtz cried out. Ferb held up a finger, and made Doofenshmirtz chase it. When Perry was nearby, he stopped, and Perry punched Doofenshmirtz. Doofenshmirtz retaliated… Perry's instincts weren't what they once were. Perry flew against the wall, and a sickening crunch was audible. Ferb rushed over to Perry, and Vanessa looked at her father.

*POW*!

"CURSE YOU, VANESSA DOOFENSHMIRTZ!" "It's muffin time, sir!" "Not the time, Norm. I was in the zone." "I thought you were defeated." "Alright, that's it. How do I release the squirrels?"

Ferb grabbed Perry, and rushed to the nearest vet. Vanessa grabbed Pinky and followed suit. "Look, I'm sorry, little boy…" the vet told Ferb when he arrived. "I'm afraid this platypus is at the end of its lifespan. There's nothing we can do." Ferb nodded sadly. "But still, can you keep him alive long enough for his true owner to come say his final goodbye?" he asked. The vet nodded, and Ferb pulled out his phone.

"All right, girls, I officially declare all of you Fireside Girls!" Isabella declared. *Ctrtrtrtr* echoed from somewhere. Phineas pulled out his phone, and put his ear to the receiver. "Look Ferb, I'm in the middle of… what? Are you sure? That's… that's terrible. And there's nothing we can do? Oh… at least I can do what? Oh… can I… well thanks… see you there," Phineas talked into it. "Isabella, come along with me. We've got so many sights to see, but not a whole load of time. We're in a hurry… Adyson, can you continue this meeting?" he then told the room.

Phineas and Isabella rushed into Perry's makeshift bed. "Perry… I can't imagine a world without you… please don't go," Phineas murmured to his pet platypus. Perry shook his head, and saluted. "Ferb?" both Phineas and Isabella sobbed. Ferb cleared his throat, and began.

"Perry the Platypus is a secret agent, who's mission was to stop Heinz Doofenshmirtz from gaining power in the Tri-State Area. He's been fighting him since we adopted him, maybe even sooner. He's always cared for us, but his work has always separated us. However, most of the times our big ideas have vanished, it was caused by Perry and Doofenshmirtz. We owe him so much… and he owes us just as much. We'll be sad to see him go," Ferb said. Isabella cried into Phineas' shoulder. "Oh, Phineas… why did he have to go?" she whispered. Phineas put his head to her shoulder, shedding almost as many tears as Isabella. "Doofenshmirtz. I'll never forgive you! …Sorry, Vanessa," Phineas shouted. Perry breathed his last breath… he… "Oh Phineas…" Isabella cried. All four of them burst into tears.

Perry's funeral was a simple affair, yet no less tear-jerking than a fancy one. The entire Flynn-Fletcher family, along with the older Fireside Girls and some of Phineas' other friends like Django, was present on one side of the aisle. The O.W.C.A. and all those who knew Perry as Agent P sat on the other side. In the middle, holding the body of the world's greatest pet, was Phineas Flynn. He laid the body squarely in the centre of the small coffin they had made especially for Perry.

"Perry the Platypus. Some knew him as an ordinary platypus who didn't do much. Some knew him as a crime-fighting elite who kept the Tri-State Area safe. No matter who the person was, Perry was there. He was great. He was good. He was… special. No one sitting before me, man, woman, child, or animal, can say that Perry wasn't one of their friends. Old boy… this is one trip outside your family that you won't be coming back from. We'll all miss you, Perry," Phineas spoke. Everyone had out something to wipe away the tears (except the smaller animals, who had to make do with the grass), as Perry was lowered into his final resting place. No one could stand to stay here after the sermon was done. Except…

"Phineas, that was a great speech," Isabella told him. "It's just sad… to know that Perry is gone forever…" Phineas sobbed. He turned- Isabella had just as many tears as himself. "Listen, Phineas. Ferb told me something that Agent P chattered to him. He said… Perry had come to see me as a surrogate sister. Phineas…" she said. Phineas gulped… Isabella was getting a little close… "I love you, Phineas Flynn. And so did he…" she whispered, and gave him… well, not their first kiss, but their most romantic one. "Phineas…" she whispered one final time.
