(Cut to the boys getting treatment at an alien spa.)

(Song: Spa Day (instrumental))

Phineas: Wow, I got to say, this is relaxing

Super Super Big Doctor: Stapler-Fist there is my toughest guard, but, boy, if he doesn't give the finest foot massage on Feebla-Oot.

Phineas: Well the pressure is perfect, so thanks Mr. Fist.

Stapler Fist: OMG, one of the Beacon of Light just thank me! I can't believe it! I'm so excited, I could actually explode. Seriously, I could just

Candace: Well, I am glad that you— (gasps as Stapler Fist just exploded) whoa! What the heck?

Shoe Monkey: Oh, geez, he got his goop all over me.

Candace: uh...what just happen?

Super Super Big Doctor: Oh, don't worry. He'll grow back.

Shoe Monkey: All right. Come on, Stapler-Fist's legs. This way.

Candace: well that was gruesome

Super Super Big Doctor: Yea, It happens whenever they get excited. Especially when they get free stuff. Birthdays here are a bloodbath.

Phineas: make a note on that Ferb: no free stuff. (Ferb wrote it down on his notebook)

Super Super Big Doctor: Now just relax. We're gonna have a beautiful day!

(Song: Our Days Out)

(Yeah, it's our days out...)

(Yeah, it's our days out...)

You and I

Should take the afternoon to unwind.

So get ready

We can lay out and rest our minds.

Go for a drive or stop for a bite,

It all depends upon your appetite.

We could do knitting,

Or copper fitting,

Weather permitting...

I never seem to have any free time.

I just need to get a little me time.

I mean, "and you time, too."

It's a girls day out, time to get away

From the hustle and bustle of the day-to-day.

We all need a little time to play.

Super Super Big Doctor: Cucumber spray?

Phineas: No doubt!

We can just do brunch or catch a matinee

Or something a little bit less cliché.

I've got this, honey,

Put your money away,

'Cause I am all about our days out.

(Yeah, it's our days out...)

(Yeah, its our days out...)

(Cut back to the trees as we pan by various weird-looking insects, until we finally meet back up with the gang. Isabella steps on a mound and surveys her surroundings.)

Isabella: This way, team. The fortress is three klicks away.

Doofenshmirtz: Wait a minute! What's a "klick"? And who put you in charge, young lady? I'm the grown-up.

Isabella: Well, some people think I'm a natural leader.

(Isabella unravels her Fireside Girl sash revealing her many accomplishment patches.)

Isabella: Huh?

Doofenshmirtz: You got, uh— You got all these for being a leader?

Isabella: Yep.

(Beat.)

Doofenshmirtz: Well, but, have you got one of these? (Doof reaches into his lab jacket and takes out a card.)

Isabella: That's a library card, and, yes, I do.

Doofenshmirtz: (puts the card back) Well, it doesn't matter, because I'm the adult. So, step aside. Doof is in charge!

(Song: Adulting)

So you say you got a patch for leading people through a jungle?

But I've got a prescription for this anti-fungal.

So I win!

Isabella: How is that winning?

Doofenshmirtz: I'm just saying I'm prepared.

Isabella: Undecided whether I should feel

Disturbed or scared.

Doofenshmirtz: I'm older and bolder,

Got this ache in my shoulder

I keep my medical records

In this manilla folder.

Isabella: Meaning?

Doofenshmirtz: Just that I lived more.

Isabella: But I've got a better feelin' for the great outdoors.

Doofenshmirtz: Ya think ya know just what to do,

But I've got a ton more experience than you

In adulting!

Isabella: Is that what it's called?

Doofenshmirtz: I know you don't know what I mean,

But you're not gonna know it till ya turn eighteen.

It's called "adulting"!

Isabella: That's not a verb.

Doofenshmirtz: When you're no longer a private, you're a sarge!

You're all grown up and you're livin' large!

Ya get to be the one in charge!

Get it off of me! Get it off of me!

It's called adulting!

Isabella: It's still not a verb.

Doofenshmirtz: Come on, back me up here.

Candace: It's not a verb.

Doofenshmirtz: Whatever.

Isabella: Can you read a compass?

Doofenshmirtz: No.

Isabella: Or start a fire?

Doofenshmirtz: No.

Isabella: Build a shelter?

Doofenshmirtz: No.

Isabella: Or change a tire?

Doofenshmirtz: No.

Isabella: Dig a hole?

Doofenshmirtz: No.

Isabella: Pitch a tent?

Doofenshmirtz: No.

Isabella: Navigate?

Doofenshmirtz: No.

Isabella: Circumvent?

Doofenshmirtz: No.

Isabella: Chop a tree?

Doofenshmirtz: No.

Isabella: Build a snare?

Doofenshmirtz: No.

Isabella: Catch a fish?

Doofenshmirtz: No.

Isabella: Fight a bear?

Doofenshmirtz: No.

Isabella: Now I think our only care,

And I think this question is really fair,

Is can you get us from here…

Doofenshmirtz: Yeah?

Isabella: …to there?

Doofenshmirtz: Absolutely!

Isabella: You can? How?

Doofenshmirtz: By adulting!

Yes, adulting!

Baljeet: He makes a salient point.

Isabella: Baljeet!

Doofenshmirtz: I'm adulting!

Baljeet: What? He sounds authoritative.

Doofenshmirtz: 'Cause I'm adulting!

I'm an adult! (dusts himself off) And therefore, I, the adult, say... this way, people, single file— (screams as he falls off a cliff and tumbles a la Homer Simpson) Ooh, ooh, whoa, whoa! (Screams)

(Splash!)

Doofenshmirtz: (offscreen) I'm okay! I'm okay! The water at the bottom broke my fall. It's awfully hot, though. It's— (stammers, screams)

(A geyser sprays Doof back up to the cliff.)

Doofenshmirtz: (screams, grunts) Okay, I can confidently say that we should go that way. (Groans)

(Dissolve to a bruised and bandaged Doof limping in the lead.)

Doofenshmirtz: So we all agree that we've passed this spot somewhere between once and not more than, like, 11 times, right?

The gang: Yes.

(Agent P stealthily trails behind them. Suddenly, a screeching is heard. The gang turn around and see a dragon-like creature flying overhead.)

Doofenshmirtz: Okay, well, that's something you don't see every day.

(Doof zaps the creature with his Chicken-Replace-Inator, and the creature is instantly replaced with the nearest chicken.)

Doofenshmirtz: See? Adulting.

Phineas: What just happened?

Doofenshmirtz: Well, thanks to my handy Chicken-Replace-inator, which some people said I shouldn't bring, it switched places with the nearest chicken. Wherever that is.

(Cut to Earth. Cut to a sign reading "Dragon Land Theme Park: 'A Medieval Load of Fun.'" We find out soon enough that this is yet another half-brained business thought up by our favorite henpecked farmer.)

Farmer's Wife: I can't believe you built a dragon theme park without anything that even looks like a dragon. And why haven't you gotten rid of that silly chicken coop?

(The chicken in the coop is soon replaced by the Feebla-Ootian creature.)

Farmer: My support group says you're keeping me down.

(Cut back to the gang on Feebla-Oot.)

Doofenshmirtz: Now, where was I? Ah, that's right. Leading. This way, people. (Screams)

(Doof once again falls off another cliff.)

Doofenshmirtz: Oh, my spleen! Ow! (He crashes into a wall.) Ow!

(The gang look up to find that Doof crashed into the fortress.)

Doofenshmirtz: (groans, pants) Oh, look, we're here! See, I told you I knew the way.
