Stacy: Who are you anyway, and what have you done to the real Buck Rockgut?
Becky: Yeah what did you do to him?
Rockgut: Oh we kept Rockgut sealed tight in his cell allright; he won't be out anytime soon (laughs)
Buck uses a morphing device to change back into his true form. The impostor is revealed to be none other than the hypnotized Darla the Baboon.
Leonard: (gasps in horror) You're Darla
Darla: That's right darlings, It's me Darla the Baboon, and there's nothing you can do to stop us. All hail Dr. Blowhole!
Leonard (annoyed): (picks up a small stone) wanna bet witch? (Throws the stone)
Then out of luck, the stone that Leonard threw hits Darla's eye, momentarily stunning her in the process.
Darla: Oww! Why you little (while covering her injured left eye and writhing in pain)
Lobster warriors: You alright Madame?
The lobster minions just continued looking at Darla who is squealing in pain as a result of being hit in the eye.
Leonard: You girls go ahead and get out of here, find Skipper and Douglas and tell them that Buck is actually Darla in disguise.
Stacy: But what about you?
Becky: Yeah what about you?
Leonard (While cranking the blaster): Don't worry about me, I don't like this anymore than you do. I'll try to hold off these guys for as long as I can. Now go before they catch all three of us.
Stacy: But?
Leonard: Go!
Becky (while tugging Stacy's paw): Come on Stacy, we have to find to Skipper
They then run back to find Skipper and Douglas to warn them about the Buck impostor. Meanwhile Darla, having gained recovery from her struggle, commands the lobster warriors to capture Stacy, Becky and Leonard.
Darla: (annoyed) Don't just stand there you lazy pokes, what are you waiting around for, Christmas? Get those varmints!
The lobster warriors target and corner the helpless koala, leaving no possible escape route for him. But before they do so, Leonard manages to blast off three of the lobsters before finally becoming overpowered and buried under the pile of Lobsters leaping on him.
Stacy (looking back at Leonard): Leonard!
Becky (while tugging Stacy's paw): Come on, we have to hurry. He'll be fine once we rescue him.
Lobster warrior: Madame they're escaping, we don't think we can catch them in time.
Darla (annoyed): Idiots, if you want something done you'll have to do it yourself.
Darla takes out a pair of bolas to capture the badgers. She gives the balls momentum by swinging them in the air before aiming it at the badgers, hoping to ensnare them both. One of the bolas successfully manages to hit Becky but misses Stacy. The device quickly entangles Becky's legs, thus preventing her from escaping, leaving Stacy as the sole badger who has one opportunity to escape.
Stacy (terrified): Becky! Noooo!
Becky: Forget about me Stacy, just get out of here. It's all up to you now.
Caught between saving her other half or running away to find Skipper, she decides to run back to the sewers and ask for help.
Stacy: I'll be back, I promise
But before she gets there, she bumps into the hypnotized Private, not knowing that he is under the control of Dr. Blowhole.
Stacy (bumps into Private): (gasps) Private it's you, come on we have to warn Skipper that Buck is an imposter (while tugging Private's flipper)
Private (hypnotized state): No, I don't think it will be necessary to tell Skipper
Stacy: What, don't be silly, of course we have to tell Skipper, what makes you think (gasps)
Before she could finish her sentence, Stacy quickly realizes that Private is already hypnotized due to the hypnotic bracelet attached to his feet.
Stacy: You're, you're hypnotized, aaah! (Runs off, letting go of Private's flipper)
Private (cranks the electric net gun): Yes, and you're next
Stacy manages to escape, but it's not long before Private prepares to fire the weapon at the scurrying badger. He successfully hits Stacy and stuns her with the electric net gun, thus capturing the last of the badgers. Darla catches up to Private, congratulating him for the work he's done.
Darla (slaps Private on the back): Good job Private. I could have done it better myself.
Private: Yes, you would have, we're only doing this to please Dr. Blowhole.
Darla and Private: Hail Dr. Blowhole! Hail Dr. Blowhole!
Darla goes on to inform Hans that they have captured Stacy, Becky and Leonard.
Darla (while talking on a video watch): Sir, we've captured the badgers and the koala.
We're now going after the other two in the sewers. With your permission, should we reattach the hypnotic bracelets?
Hans (seen on the video phone): No, I have something else planned special for Skipper and his so called team. Tie them up and place them in the room where the top secret project used to be. And by the way, just let Skipper and his friend go through the sewers, eventually they'll find their way inside and when they do, we'll be waiting for them.
Darla and Private smiled at each other as if knowing what Hans meant.
Darla: Your druthers is my ruthers.
Private drags the immobilized Stacy to an undisclosed location as she screams for help, hoping that Skipper can hear her plea for help.
Stacy: Skipper!
Meanwhile, at the same time that Stacy was screaming for help, Douglas hears her desperate plea for help and he taps Skipper lightly on the back to tell him that their friends are in trouble.
Douglas: Skipper I think I hear them crying for help, we have to go back and save them
Skipper: Sweet mother MacArthur! You're Right! Let's move out
But before they could do so, a series of traps were activated, delaying their heroic ascent back to the top. They were greeted in surprise when a bunch of blow darts come flying out from the walls.
Douglas: Skipper watch out for those blow darts!
Skipper: Evasive!
Luckily for them, Skipper and Douglas were able to dodge the incoming projectiles.
Then a pillar of flames shot out from the ceiling emanating against the two penguins. Out of panic, they immediately slid out from the fire infested traps with ease, thus avoiding a fiery end and being burned to a crisp.
At that moment, when the penguins think they are safe from harm, a giant robot in a gold plated suit of armour appears from nowhere, warning them that they have trespassed on private property.
Robot: Intruder alert, intruder alert, you have trespassed upon private property. I have been designed by Dr. Blowhole himself to get rid of you. Now leave before I am forced to evict you two.
Skipper: Make us, were not leaving this place 'till we get our friends back. And you can't stop us you mechanical monstrosity.
Robot (preparing to use its laser): Fine, you've asked for it punks.
Douglas (annoyed): Oh I hate it when they do that
The robot fired at its target with huge pulses of light; at the same time it also uses its large knuckle hands to crush both penguins flat to the ground. The darkness of the sewer made it harder for them to see the robots attacks with their bare eyes.
Douglas (while avoided being pounded): Great, now you've made it even angrier
Skipper: Yeah and this is why I never trust robots in the first place, these mechanical machines just don't like to play fair.
While dodging the robots attacks, one if its laser accidentally fires at the sewer walls, causing the whole structure to collapse upon itself. Realizing they have to get out fast in time or be crushed under the rubble, Douglas tells Skipper to escape the sewers while he tries to hold off the mechanical machine.
Douglas: Skipper you have to get out here now, the walls are starting to collapse. Don't worry about the robot I'll take care of it. You just have to go on without me.
Skipper: What about you, I can't just leave you. It's the penguin credo, never swim alone.
Douglas (while fighting the robot): I'll be fine I promise, I won't die I assure you that. Just make sure when you get out of here, you save all of your friends and the world from Dr. Blowhole. Now go.
Realizing he has no other choice, Skipper escapes through the manhole where they entered a couple of minutes ago. And just when he barely escapes a harrowing encounter, an explosion is heard from deep inside the sewers. Skipper ran for cover when he heard the explosion rumbling through the sewers.
Skipper (shouting): Douglas!
It was then he realized that Douglas was gone; his friend had sacrificed himself in order to save Skipper from being annihilated.
Skipper: I promise you my friend, you won't be wasted. It's time I take down Blowhole and his evil minions once and for all. Now it's personal than ever before.
He hurries along to help his friends who were heard screaming earlier; unfortunately what he finds is nothing more than rocks and dirt. With nothing more to lose, he heads on to the secret base to infiltrate Hans's secret base alone without any of his companions.
Meanwhile in an imprisonment chamber, the real Buck Rockgut is still locked tight in his cell, possibly trying an attempt to escape the confined corners of his room. Unfortunately for him, the doors of his cell are equipped with electric shocks that deter him from slipping away, making an escape attempt even harder.
Rockgut (muttering): Hmmm, It seems the doors are armed with an electric shock. I can't escape unless I touch the handle bars of the entrance door. Maybe I don't have to; I'll just let someone open the door for me and then I'll ambush them from behind, yeah that's right it will work. I'll just have to wait 'till someone comes along, but that could take weeks, oh well I'll just have to wait.
Then an opportunity comes along, he hears an approaching lobster. The crustacean was assigned to deliver the food to Rockgut and the only way to do that is to open the door and hand over the food. In order for an ambush to be successful, Rockgut will need to find a way to conceal himself from his attackers, and when the time comes they are unaware of his location, he attacks them from behind and knocks them out cold.
He spots the dark ceiling as the perfect concealing place for an ambush, Rockgut just needs to buy a few time to stay hidden in the roof.
Lobster: Ok Mr. Rockgut here is your food, enjoy while it...
The lobster couldn't believe his eyes; Rockgut is missing from his cell. He quickly scours through the ring of keys looking for the right one to open Buck Rockgut's cell. The lobster wanders around the room in a panic state in order locate Buck. Realizing that he had escaped, he radioed his co-workers for reinforcements and to tell them that the penguin has flown the coop.
Lobster (on the walkie talkie): Code Red, Code Red, we have an emergency, Special Agent Buck Rockgut has escaped from his cell, I repeat Spe...
Buck cuts him off and ambushes him from above the cell.
Rockgut (falls down on the lobster): Hey! Up here, surprise
Lobster: Aaaah!
Before he can finish, Rockgut falls down on from the ceiling and attacks him, making his escape attempt successful. The fighting goes on for a short time, and it is already implied that Buck fought his opponent with ease and for a short moment later imprisons him from the inside.
Lobster (panicking): Hey listen buddy; you can't keep me locked up here can you? Come on, please let me out (fake crying)
Rockgut: Oh yes I can, and you stay there 'till I say you can
Lobster (panicking): Oh come on, were friends aren't we?
Rockgut: Not in this lifetime punk
Rockgut then leaves the lobster still locked up inside his prison and proceeds to free the other prisoners. Initially he goes to Kowalski's jail cell to free him and to snap him out to consciousness. He violently shakes Kowalski's long, unconscious slender body.
Rockgut (while shaking Kowalski violently): Wake up soldier, wake up; we need to free the others and get out of here.
Kowalski (dizzy): Ugh, where am I? What happened?
Rockgut: You were imprisoned soldier, now get up, we need to move fast
Kowalski: Now I remember, I tried to escape lots of times but I always ended up being captured, it looks like even my brain isn't that smart enough to outsmart Dr. Blowhole, by the way, thanks for saving me, I wouldn't have gotten out from that cell if it wasn't for you Buck.
Rockgut (giving a salute to Kowalski): No problem soldier, it's all in a day's work. Now quit your fantasies and help me to free the others.
Kowalski: Right. Sorry 'bout that.
Without wasting time, Rockgut and Kowalski manage to free the remaining imprisoned animals; one of those prisoners seen is Joey, one of the missing zoo residents from Central Park Zoo. His bad temper and aggressive characteristics made it harder for them to place a hypnotic bracelet on his leg. So, as a last resort, they decided to imprison him.
Joey: Oi, get away your dirty claws away from me, I'm a boomer and I can take you down in seconds mate.
Rockgut: Relax Kangaroo were not here for a fight, we came here to get everybody escape
Kowalski: He's right Joey; we come in peace, really.
Joey: Hey, you're that digger from the zoo. Alright I believe you, but no tricks mate.
Kowalski: I don't know what you meant by digger, but fine, no tricks.
Moments after freeing every animal, they slowly proceed to sneak out of the cell without being noticed. Rockgut tells Kowalski that Joey might be useful to help them fight off against those lobster guards.
Rockgut: Umm Kowalski isn't it?
Kowalski: Yes I am Kowalski, why? Do you a question?
Rockgut: Something likes that, I'm asking you a favour, could you convince Kangaroo boy over there to distract the guards while we destroy the top secret project. Not only him, could you at least convince everybody to join in.
Kowalski: Sure, after saving me back there, I definitely owe you one
The tallest penguin Kowalski turns to Joey and the other animals for aid, convincing them to beat up those unsuspecting lobster guards.
Kowalski: Umm Joey, I'm asking you a favour if you and the other animals would like to beat up those guards. Are you in favour of that decision?
Joey (punches Kowalski lightly on the arm): Sure, we'll give it a fair go. After all, we owe you one back there.
Kowalski: Hmm, I guess karma does apply here, although there is no scientific basis for that phenomenon. Still the results are really quite convincing.
Meanwhile, one of the lobster guards spot Skipper approaching a small cabin, Skipper very wells knows that's it's the entrance to the secret hatchway so he can get enter the underground base.
The lobster informs Hans the Skipper already on his way alone.
Lobster: Sir the target is approaching the base; I repeat the target is approaching the base with no companion in sight.
Hans: Perfect, with Skipper alone and no one to help him, he doesn't stand a chance against my hypnotized army. And Dr. Blowhole's plan to rule the world will finally come to fruition, and I, Hans the Puffin, will become the most respected evil sidekick in the whole world. (Laughs maniacally)
The final scene shows hypnotized Private, a feral Marlene, Bada and Bing, Darla, Savio, and some lobster warriors, together with Stacy, Becky and Leonard all tied up to a chair, eagerly waiting for Skipper to arrive.
For those of you who are wondering what Darla had said, "Your druthers is my ruthers", it means "You're preferences are mine", "We agree".
