(Sometime later. The gang are still following the aliens.)
Borthos: Finally, we have come to a place of safety. Behold. The hidden city of Cowardalia.
(He pulls a lever revealing a dark cave.)
Buford: (sarcastically) An old dark cave. You must be very proud.
Borthos: Oh, this is just the cave entrance to the city of— (grunts) Borthos, every time you bring somebody here, you do this too soon. (sighs) Follow me.
(Cross-dissolve further in the cave. They approach a boat-like substance.)
Borthos: Everyone, climb aboard.
(They do, and the boat goes over into the water.)
Borthos: Behold, the city of Cowardalia.
(The group passes through two monuments of two Cowards cowering in fear.)
Buford: So ya live in these big statues?
Borthos: Uh, no, no, no. That's just monuments we built up. The city is beyond those and— Oh, Borthos, come on!
(The gang finally reached the city. Borthos inhales to speak, but his thunder is stolen.)
Ernox: The hidden city of Cowardalia.
Borthos: Really, Ernox? Really? (sighs) Make yourself at home.
(Garnoz, an older Coward, emerges from underground.)
Garnoz: Borthos, you escaped from the scary ones. Did you hide under a tarp? Did you cower under some boxes? Did you stand very still and pretend to be modern art?
Borthos: No, Garnoz, we did not hide or cower or stand still. Although, Brizak over there is an excellent example of cubism.
(Whip pan to Brizak, who, indeed, could be mistaken for one of Picasso's masterpieces.)
Borthos: These aliens helped us escape.
Garnoz: Thank you for saving my people. You may hide and cower with us here in Cowardalia as long as you wish.
Candace: Thanks for the offer, but we're worried about my brothers. We've gotta get back to them somehow.
Doofenshmirtz: And I have to get back to my daughter on Earth.
Garnoz: We would love to help you, but we really can't.
Borthos: We're cowards.
Garnoz: Let me explain. We used to be a free and happy, cowardly people.
(Flashback. Yep. It's backstory time.)
Garnoz: (voiceover) Then one day, she arrived.
(A mothership not unlike that of the one that captured Phineas and Ferb looms over the planet. Sure enough, Super Super Big Doctor and her crew emerge from it.)
Garnoz: (voiceover) And she brought with her her evil plant of doom. She sprayed us with mind-controlling spores and put herself in charge. She forced us to build her castle, lavish her with treasures, and make low-quality TV shows.
Super Super Big Doctor: (laughs)
(She pushes a buzzer, and the literally captive audience laughs feebly.)
Garnoz: (voiceover) Then one day, the spores began to disappear. Our minds became clear. So we did the only thing that we could do…
(The Cowards appear to hold their pickaxes threateningly, but…)
Garnoz: (voiceover) We ran away like frightened toddlers. Sadly, some of our people are still under her control. And now, we hear that she has found some unique people. Who has the innate power to make her sinister shrubbery grow once more.
(End flashback as the gang realizes.)
The gang: (gasp) The Beacons of Light!
(Cut to Phineas looking at the shriveled plant.)
Phineas: What the heck is this thing?(The plant comes to life and startles Phineas. He turns around to see Super Super Big Doctor behind him.) (sighs) You startled me.
Super Super Big Doctor: I see you've met Mama.
Phineas: This plant is your mother?
Super Super Big Doctor: No, silly. I named her after my mother, whose name just happened to be Mama. Weird coincidence. She was also green and very controlling.
(Cut back to Cowardalia. Candace steps onto a mound and addresses the populace.)
Candace: Listen, everyone, we came all the way across the universe to save my brothers. And we're not going home without them. If you care about your people as much as we care about Phineas and Ferb, then please help us.
Garnoz: You do not understand. All we do is cower. We are called the cowards. In our language, it means "coward".
Isabella: Just because you are cowards doesn't mean you have to be cowards. And if you can be brave just this once, from here on, "coward" could mean "mighty warrior." What do you say?
(The cowards just stand and stare.)
(Cut back to Phineas, Super Super Big Doctor, and Mama.)
Phineas: But what's it for?
Super Super Big Doctor: It's for you. This is why we're collecting your Remarkalonium. Check this out. Bring in the device!
(A large device emerges from the floor to ominous music. The device unfolds to reveal what appears to be a treadmill.)
Phineas: Wait. Is this a treadmill?
Super Super Big Doctor: Remarkalonium is Mama's lifeblood. She'll shrivel up and die without it. Hop up here.
(Two mechanical arms pop out of the treadmill and take Phineas onto it.)
Phineas: Whoa!
Super Super Big Doctor: But thanks to you, now she can grow again and produce her wonderful mind-controlling spores.
Phineas: Oh, well it's nice doing something environmentally friendly— Wait. Mind-controlling spores?!
Super Super Big Doctor: (scoffs) Yeah, how do you think I got to be in charge in the first place? But now the spores have been wearing off. And more of the populace is slipping from my control every day. See? There's one now. Uh, guys. We're losing another one. Guys!
(The coward runs away dropping his tray.)
Super Super Big Doctor: And… there he goes. Right out the door. Really? One of you guys couldn't have run after him? Ugh! I'm sure he hasn't gotten far.
Guard: (offscreen) Hey, you! You're not allowed in that shuttle craft! You're not allowed to—
(Shuttle craft whirs, departs offscreen, but then crashes.)
Super Super Big Doctor: Ha! Ha! Our shuttles are notoriously hard to fly. Bad design really.
Guard: (offscreen) Hey! You, getting out of that stolen shuttle, freeze!
Super Super Big Doctor: Got him now! There we—
Guard: (offscreen) I said, "freeze!" Hey! Stop! Stop! Get away from that hover bike!
(Hover bike whirs, departs offscreen.)
Guard: (offscreen) Get away!
Super Super Big Doctor: (to her henchmen) Any chance those are hard to fly?
Shoe Monkey: A child could fly it, Your Highness.
Super Super Big Doctor: (groans, to Phineas) Anyway… So that's why you're so important to— WHAT THE?!
(The hover bike crashes through the window.)
Super Super Big Doctor: (to her henchman) I thought you said a child could fly it! Now, just how—
(The coward escapes.)
Super Super Big Doctor: And there he goes again. (grunts) See why I need you? I gotta keep 'em under control. I need new episodes of Clown and Mailman.
Phineas: What you're doing is— is awful! How would your brothers feel if they could see you now?
Super Super Big Doctor: Why don't you ask 'em?(The screen shows Super Super Big Doctor's younger brothers locked up in a cage playing with a makeshift ball.)(Cut to her brothers' cage. A screen appears with her on it.) Hey! You made a ball? I told you not to play in the dungeon!(A laser blaster destroys the ball.)(Cut back to Phineas and Super Super Big Doctor.) (sighs) Now let's grow some spores.
(She turns on the treadmill and Phineas starts walking.)
Phineas: Wait. Wait. How could you imprison your own brothers?
Super Super Big Doctor: Oh, it was super easy. I lured them in with these cheesy snacks—
Phineas: No, I mean, how could you?! I'd never do something like that to my family or my friends!
Super Super Big Doctor: You already did.
Phineas: No, I didn't.
Super Super Big Doctor: I said, "I'll take care of 'em," and you were like, "Would you? That'll be nice." So I thought you were down with the whole dungeon thing.
Phineas: Wait, you threw my sister and my friends in the dungeon?! That's not what I wanted. I never wanted to hurt them!
Super Super Big Doctor: Wow. Wow, wow, wow, wow, wow. this. This is eye-opening. Have I misread things or what?
Phineas: Yeah, I'd say you have. So can we—
(Super Super Big Doctor pushes a button on a remote, chaining Phineas to the treadmill and speeding it up.)
Super Super Big Doctor: oh and just so you won't feel alone, I was able to find your brother (the door is open and it reveal to be Ferb in the treadmill being hover to Phineas)
Phineas: Ferb!
Super Super Big Doctor: my men found him lurking around in places he shouldn't be which would have disrupt everything
Phineas: No! Let us— Let us go!
Super Super Big Doctor: And here I thought it was too good to be true. I thought I finally found someone simpatico. And it turns out you and your people exhaled Remarkalonium.
Phineas: Remarkalonium? What is that anyway? Is it even real?
Super Super Big Doctor: Of course. In your language, I think it's called "carbon dioxide." Or CO2.
Phineas: Wait, your rare element is carbon dioxide? Everybody exhales carbon dioxide.
Super Super Big Doctor: Uh, we don't. We inhale oxygen and exhale oxygen. (then she smirks) but that all changed when my people did some observation on the prisoner that came with you…
Phineas: What? I thought you sent them home.
Super Super Big Doctor: eh so I fib a little, anyway it got me into thinking, if you two and the prisoners have Remarkalonium then imagine if your planet have some as well.
Phineas: no you wouldn't
Super Super Big Doctor: oh I would, and beside I thought you would understand since the universe is against you and all that.
Phineas: (stuttering) Well I..I don't..
Super Super Big Doctor: Oh. (chuckles) Oh, this is— something, I guess you still got a soft spot for your planet, that's cute. But of course it's pointless for you to stop me. Your planet can feed Mama forever. And I can have hundreds of castles and smoothies and hit TV shows! Braxington-ton, Shoe Monkey, fire up the ship! We have an even bigger planet to conquer.
Phineas: (low tone). No
Super Super Big Doctor: We'll load up the portable CO2 generator to the rest of them
Braxington-ton: What now?
Super Super Big Doctor: Them, dummy! Gotta keep Mama alive until we get to Earth.
(The two chain the treadmill to the floor.)
Super Super Big Doctor: (to Phineas) Been a heck of a day for you, huh? Threw your sister and friends in jail then threw your whole planet under the bus. Heh. I guess it is your worst day ever. (maniacal laughter as she left)
Toilet Flower: All right. This way, "Beacons of Light."
(He attempts to control the treadmill's levitation but it keeps crashing.)
Toilet Flower: Okay. This way, Beacon— (shouts) Here we go. (mutters)
Henchman: Have you done this before?
Toilet Flower: Yes, I've done this before. (muttering)
Henchman: Doesn't look like it.
Toilet Flower: I've done this before. Now that oughta do it. (shouts) (under his breath) Controls are stupid. I'm not stupid.
