Narrator. (Calendar flips to the last day of summer; Music plays) There's… only one day left of summer vacation, before fall and school come to end it! (Zoom in to Flynn-Fletcher backyard) So… the annual problem for this generation, is finding a good way to end... it! Like… maybe…!
Phineas Flynn-Fletcher. (Jamming on his guitar; Ferb is playing the drums) Building a rocket,
or fighting a mummy, or climbing up the Eiffel Tower. Discovering something that doesn't exist, or giving a monkey a shower. Surfing tidal waves, creating nanobots, or locating Frankenstein's brain. Finding a dodo bird, Painting a continent, or driving our sister insane.
Candace Flynn-Fletcher. (On the microphone) Phineas!
Phineas Flynn-Fletcher. …As you can see, there's a whole lotta' stuff to do before school starts on the very first day of Fall. So… stick with us because Phineas and Ferb are gonna' do it… all! So stick with us because Phineas and Ferb are gonna do it all!!!
Candace Flynn-Fletcher. Mom! Phineas, and Ferb are making a Musical!
Ferb Flynn-Fletcher. (Bangs on the drums a final time; Phineas strums a lasting beat on the guitar)
Act I:
(Stage: Phineas and Ferb are outside the Flynn-Fletcher house with Perry the Platypus, Isabella, Pinky the Chihuahua , Baljeet, Buford the Bully, and surprisingly Irving. Pinky is shaking like always, and our beloved are dealing with the fact of Summer coming to an abrupt end.)
Phineas. "What!? Summer's officially ending tomorrow… how could it be? I thought we still had like… [3] more seasons… I mean weeks to go?" (He would look down; saddened)
Ferb. "Time passes when you're having fun…" (He held up a finger; making a logical point.)
Isabella Garcia-Shapiro. "Yeah…, this summer sure has been great." (Isabella said with her usual smile; the hearts in her eyes saddened to her crushes sadness.)
Baljeet. "Friends, let us remember all of the good times we've had…" (As the flashbacks occurred, a song could be heard.)
Backup-singers. "Summer, I love summer, Give me that summer time, summer, maybe 86,400 seconds that's fast. Have to make summer last." (They repeated it several times, them stopping after the flashback ended.
Buford. "Hey. How come I wasn't in that flashback of yours?" (He looked furiously at Baljeet; he cracked his knuckles, preparing to do his job as a bully.)
Phineas. (Smiled again) "Yeah… they were." (He looked around, noticing his pet platypus' disappearance.) "Hey. Where's Perry?"
Isabella. (Looking around, noticing her pet Chihuahua is gone too.) "Hey! Where's Pinky?!"
Irving. (Jumping up and down, laughing like a schoolgirl.) "He said the words!"
Baljeet. (Given a Wedgie; rolling eyes at Irving) "What a nerd!"
Phineas. "Hm…" (Music plays)
Where are you Perry? – Song Start
'Where did he go?
Why can't I know?
Every day he vanishes,
Without a trace.
Why can't I find his…
Simple face?
Oh… Perry!
Perry!
Why is it so tough?
Perry!
Was I too rough?
Perry!
Please… come home.
Perry…
Don't leave us alone…'
Where are you Perry? – Song End
(Music Stops)
"Hey guys… lets go see if we can find, Perry & Pinky. Maybe… hey Ferb! Maybe we can use that Secret Agent lair you made us around the beginning of the summer to find Perry and Pinky! You didn't destroy it did you?"
Ferb. "Actually I-…" (He was interrupted)
Phineas. (Pushing in on the Tree's lair entrance chute; it opening up) "Yes! I knew you wouldn't let us down Ferb! C'mon everybody!" (He slide down the chute-slide)
Backup-singers. "Summer, I love summer, Give me that summer time, summer, maybe 86,400 seconds that's fast. Have to make summer last."
Everyone. (Slide down)
Major Francis Monogram. "Agent P, Dr. Doofenshmirtz is up to his u-u-u-usu…! Ah!" (Ducked down under the camera screen; whispering) "Carl! I thought I told you to tear out the Tree Entrance!"
Carl the Intern. "Sir, I hired a Demolition, but they can't do it with the Flynn-Fletcher's around. Sorry, sir."
Monogram. "Great Carl… just great."
Perry. (Turned to notice the boys, panicking, and removing the Agent Fedora, making his Platypus noise)
Phineas. "Hey. Where'd that guy go?" (He looked around, walking to Perry, and picking him up)
Isabella. "So this is where Perry went… now we just need to find Pinky."
Phineas. "Perry. You see Pinky walk by here?" (He looked at his pet platypus, just remembering something) "Oh right, you're just a platypus… of course. Now where, oh where, could little Pinky have shook off to?"
Baljeet. "Well… maybe he went back to Isabella's house?"
Isabella. "No way, Pinky never runs off just to go to my house… Pinky usually pops up out o-…"
Phineas. "What the? Look guys… some kind of Fedora was left lying on the ground…?" (Picks it up; he pulls a hair out of it) "And… look, this green hair sort of reminds me of… Perry's fur…"
Ferb. "Perhaps this is where Perry runs off to everyday…?" (Everyone looks at Perry)
Perry. (Makes his Platypus sound; beginning to get nervous)
Monogram. "Carl, we better make a distraction so Agent P can get away from his owners', and his owners' friends, to stop Doofenshmirtz."
Carl. "I'm on it, sir."
Monogram. (On-screen again.) "Hehehe… hello, Agent P… uhh… again. We need you… uhh… for a mission! Yes, that's it! You've got a 'special assignment' to do today."
Phineas. "An assignment… I don't know, I'm kind of busy… what do I got to do?"
Monogram. "Umm… the dastardly, Doctor Carlon… Internus… umm… has created a Laser beam to… freeze Danville's Freshwater supply. …We need you to put… a… stop… to… it."
Phineas. "Hm… sounds important… c'mon guys. This should probably be fast. Grab all the spy gadgets you can."
Carl. (Off-screen) "Sir! The kids could get seriously hurt… and also me! I hope you're sure about this. Cause… I don't want to hurt them?"
Monogram. (Turned off screen; facing Carl.) "Well… do you want Agent P to be discovered, either?"
Carl. "No, sir. I'm sorry… I'll do what I can. Just send Agent P over to Doofenshmirtz', cause if your briefing with Agent P was correct… we could have a Final Ice Age on our hands…"
