[Irving works as a new intern at the OWCA headquarters, taking over from now Commander Carl, heard a beeping sound and wipes the dust covering Dr. Doofenshmirtz's picture in the Evil Scientist Alert System.]:
Sir, it's the old Evil Scientist Alert System! It's showing "-inator" activity on a Doctor... Dooferd...
Doofenshmirtz? Great googly moogly! I thought he'd given up his evil ways when we placed him as a high school science teacher. It's too bad Monogram isn't around to see this.
Well, sir, he's gone to a better place.
Yeah. [self-reflecting as the music starts to fade] Oh what the heck, I'm calling him!
[Carl dials the telephone, and calls a now retired Major Monogram who is on vacation]
[responds to the telephone call while relaxing] Monogram...
Carl! I'm great. Bora Bora really is a better place. How have you been, man?
I've been well. Guess who's just set off the "-inator" alert?
[chuckles on the news] Just like old times. Well, tell him "Hi" from me.
[referring to his and Isabella's childhood and their wasted chances, in song] And now our endless summer is finally coming to an end;
I tried to make the most of every day, but now the years just seem mis-spent…
What might have been?
[Phineas arrives at Isabella's house. As the delivery truck moves away, Isabella is seen sitting down at the steps at Phineas' house. The two eventually looked at each other for a moment.]:
[walks towards Isabella] Watcha doin'? Hehe... [Isabella then smiles at him] Is this step taken? [referring to the steps at Phineas' house where Isabella is sitting]
[allows Phineas to sit beside her] I actually came by to say goodbye to you.
Yeah, I'm going two weeks early because I'm an RA, and in soccer, debate camp, student government.
Yeah. I haven't seen you all summer.
I've been busy. [Isabella pauses]
You know, Baljeet said something funny. He said you had a crush on me back in grade school.
Oh! Yeah, I had a big crush on you.
Really? I thought I was being so obvious.
Absolutely clueless. Sorry. [Phineas pauses]
I sort of gave up when we got to high school.
Yeah. I think that's when I started having a thing for you.
[The two then briefly pause as they both look at each other when Isabella realizes something]
Well, that's unfortunate timing.
Yep. You're off to college.
Tri-State State. Have you decided where you're going yet?
[Phineas brought out two acceptance letters he saved] You know what, I just did.
[Isabella glances at an acceptance letter from Danville U] Oh, huh.
Hey, what's wro-? [retrieves Danville U's acceptance letter from Isabella] Oh shoot! I'm sorry, heh, wrong letter. [passes Tri-State State's acceptance letter to Isabella]
Well, I guess I'll be seeing you in two weeks.
[Candace's alarm goes off saying "I know where we're gonna do today"]
I know what we're gonna do today.
And I know what I'm gonna do today! Bust you guys once and for all! Do your worst or your best. Just make it big and bustable, so I can show Mom!
Wow! That was awfully supportive. And you said Candace wasn't a morning person.
This is it, Candace: the last day of summer vacation! Your last chance to bust the- [Candace slips on a rollerskate and skateboard and falls down the stairwell onto a wagon] Why do we have this many... wheeled objects lying around the house?
[Last lines of the series]
[The entire cast enters the house as Candace and her brothers point and smile at each other. Before entering the house, Phineas waves goodbye to the viewers]
[Danville Middle School; Phineas and Ferb are doing a presentation together with visual aids about their prior summer escapades in a classroom]
And the time loops just kept getting smaller and smaller. And then, using Candace's spoon, we saved the world… Again! And that's what we did for summer vacation.
[Ferb pops a confetti popper]
TTeacher
[impressed] That's a fascinating report, Phineas. We appreciate you breaking it up into nine months of installments for us.
Well, we wanted to be thorough.
And you finished just in time for the end of this school year!
Yeah, I can't wait for tomorrow! The official first day of summer vacation!
Yeah, but we don't have to wait that long.
Good morning, Agent P. I know you've been on venomous insectoid robot duty for the last nine months, but I have good news! Well, news. We suspect that Doofenshmirtz is back to his evil ways. And by "suspect", I mean he emailed us.
He also updated his social media status to "evil again".
[A screenshot of Doof's Instagram with the caption "evil again" appears on the screen]
Yes, it's all very alarming, Agent P...
[Pan away from the monitor, where it's seen that Perry has immediately left his lair]
[seeing a Linda-shaped cloud in the sky, floating over the Flynn-Fletcher house] Guys, is it just me or does that cloud kind of look like your mom?
No, she's right! Look! That is Mom!
Yes! I recognize that look of tired disapproval anywhere!
LCLinda Cloud
Who wants pie?
[looking over his tablet] Inexplicably, your mother's vaporized bits have coalesced with the high humidity in the air to form a "cumulo-mom-bus" if you will.
In English, nerdy boy. [Baljeet hands him a Nerd-to-English dictionary] Oh, a Mom Cloud!
[with Candace panicking back and forth behind him] But she looks very unstable.
Guys, I know we have to do today! Save Mom!
[]
Grab anything what we might need!
[]
I brought Mom out, I bumped out the fan. It's my fault.
[Cut to Phineas and Ferb on the bumper cars. Candace runs into them.]
Wa-wa-wa-wa-wait! What can I do?
Oh, uh, grab the Whack-a-Pest and follow us!
She has absorbed too much water! She is nearly two tons! We cannot fire the device until she is close to her normal density! Otherwise, she could explode!
So how the heck do we get ride of all that water weight?!
Water? Wait! Waterworks! That's it! [goes into the house and upstairs to her room, carrying the family portraits] Mom! [lets go of the pictures and they float up to the Linda Cloud]
[The Linda Cloud looks at all the family photos from every year on the first day of summer and sobs in happiness]
[Cut to the park where a mother is scolding her picky son, who is grumpily crossed his arms and he refusing to eat his broccoli.]
MMother
No dessert until your plate is clear.
[The inator gets the broccoli off of the plate.]
[Cut to the family enjoying their dinner. The inator grabs the whole table.]
