[The episode starts with the Shredder's lair, where Shredder's holding the tortured Kraang in his left hand from the last episode.]
Shredder:[strictly] Why were you hunting the turtles?
[Kraang speaks in an alien language, which Shredder does not understand.]
Karai: They don't talk much outside their little houses.
[Shredder puts Kraang to the damaged exo-suit, he gains control of it. Kraang is about to stand up, but, due to its damages, he can't move. Kraang squeaks in frustration.]
Kraang: Kr-kr-Kraang is lacking the knowledge to answer the questions that the one known as Shredder is asking of Kraang.
Shredder: Do they all speak like this?
Kraang: Even if Kraang is possessing the knowledge, the one known as Shredder will never be getting that knowledge from Kraang.
Karai: You didn't have any other plans for today, did you?
Shredder: Let's try again. [points his blade at the kraang] Why were you hunting the turtles?
Kraang: The ones known as the turtles are protecting the life form needed by Kraang, the one known as April O'Neil.
Shredder: Who is this April O'Neil?
Kraang: She is the one known as the One. She is the link which is missing in the plan which is the plan of Kraang.
Karai: So this April O'Neil is at the center of everything.
Shredder: Then perhaps we can use her to draw the turtles out of hiding. Karai, find this girl, and bring her to me.
[Karai goes on a hunt for the known girl: April O'Neil.]
[theme song]
[In the lair, turtles, April and Splinter are training. Leo easily dodges Donnie's attack, grabs his bo staff and impressively punches him away with his one hand. April tries to hit Splinter, but he turns her head to the turtles. Raph comforts Mikey.]
Raph: What you gonna do? What you gonna do? What you gonna do?
[Raph attacks...but Mikey's Ninjitsu technique gets impressive, after he dodges Raph's attacks, grabs his hands and kicks him to the ground.]
Mikey: Booyakasha! You got faced! Thought you had me, but I played you like a trombone.[mimics trombone]
[Raph grabs Mikey]
Raph: Play time's over, tough guy!
[Raph defeats Mikey.]
Mikey: Put me down! Enough! Uncle!
Raph: I don't see you tapping out.
Mikey: I can't move my arms.
Raph: Then tap your horrible, disgusting middle toe. [drops Mikey]
Mikey: Don't worry, stubby. You're not as horrible as he says.
Splinter: Michelangelo, why did you give up so easily?
Mikey: There was nothing I could do.
Splinter: There is always something you can do. Observe. Raphael, kannuki jime!
[Raph struggles to lift Splinter]
Splinter: The key is to unbalance your opponent.
Mikey: But how?
Splinter: However you can. For example...
[He uses his tongue, licking Raph, causing him to yelp and then knocks Raph.]
Splinter: You see? There is always a way. Blech, and you need to take a bath.
[later on]
Crankshaw: The landing party is under attack by the digesters! We have to save them!
[Crankshaw gets slapped]
Ryan: If we keep bailing them out, they'll never learn to take care of themselves.
Crankshaw: But this is their first mission, and they don't even have weapons!
Ryan: Then they'd better learn fast. Say, Doctor Mindstrong, weren't you in love with that one?
Mindstrong: I was, Captain.
Ryan: Well, it looks like you both learned a lesson today.
Donnie: Hey, guys. Guess what April and I have been up to. That's right! Analyzing sewage.
Raph: Who says you don't know how to show a girl a good time?
[in the lab, Donnie placed down a jar of liquid.]
Donnie: April and I were going through some files on the Kraang storage device. We found out that they're using a special process to change Earth's water into Kraang water.
April: They've already started the process. We found a low concentration of Kraang chemicals in the sewage.
Raph: And I take it that's a bad thing.
Donnie: Watch what happens when I dip this slice of Mikey's shrimp and sardine pizza into pure Kraang water.
[While he puts the pizza in the water, it dissolves.]
Mikey: How do you sleep at night?
Donnie: Presently, there's only a tiny bit in the water supply, but the concentration is increasing, which means...
Mikey: Every slice of pizza in New York will be destroyed?
April: Along with anyone who uses water.
Mikey: I don't want to live in a world without pizza.
[Mikey accidentally caused the beaker to fly off when he grabbed the pizza box]
Donnie: Look out!
[The kraang water landed on April. The turtles squeal in fear. But nothing happened to her.]
Donnie: Nothing happened to you.
Mikey: Maybe it's 'cause she's not made out of pizza.
[The scanner bleeps, catching their attention.]
Donnie: The scanners located the Kraang facility transforming the water supply, which is right here. We gotta stop it!
Leo: Looks like we got a mission. You coming, April?
April: Sounds like a blast, but unfortunately, it's on the bottom of the East River, and equally unfortunately, I have an essay due. Plus I wouldn't mind a little human food.
Mikey: Pizza's human food.
April: Not the way you eat it. [leaves]
Donnie: Whoa, whoa, whoa, you're going topside? You got your T-phone, right?
April: Donnie, don't worry. I'll be fine.
[April leaves the lab.]
Leo: So, Donnie, how are we gonna get out there?
Donnie: Don't worry, guys. I've been working on something that is pretty awesome.
[Later, Donnie had invented a sea turtle submarine. And the turtles are forced to use bicycles to move it.]
Raph: This is not awesome.
Leo: Seriously, Donnie? A submarine powered by bicycles?
Raph: You know what would have been more efficient? Swimming!
Mikey: Ha!
Donnie: Hey, pipe down, guys. Kinetic energy is the only way to charge the engines, which should be done right about now.
[he activates the sea turtle sub. The turtles huffed in exhaustion.]
Leo: We're almost there. Up periscope.
[Leo used the periscope that looks like a toilet lid.]
Leo: Uh, Donnie? Any chance this Kraang facility looks like a giant sea mutant?
Donnie: Oh, that's not a mutant. Based on his physiology, I'd say the Kraang brought him here from Dimension X.
Leo: How is that less horrifying?
Donnie: It's not. I just like to be accurate.
Raph: Well, whatever it is, it looks like it's guarding that.
Donnie: Wow.
Leo: Let's go stealth.
[Meanwhile, April is walking down the street as Karai, in her casual clothing, watches. She looks at the menu at Murakami's shop.]
April: Hmm, this is new. What is this thing?
Karai: Oh, that's how you order. They have these in Tokyo. You give this to the chef.
April: Oh, thanks.
[She inserts a coin]
Karai: Mind if I join you?
April: Sure. Why not?
[April enters the shop.]
April: Hi, Murakami-san.
Murakami: April-chan! How are you? [ She puts the token down] Ah, pizza Gyoza.
April: Hai. Chou Oishi.
Karai: You speak Japanese?
April: I picked up a few words from my brothers.
Karai: Brothers? Tell me about them.
April: Oh, you know, just crazy-
Karai: Animals?
April: Pretty much.
Karai: Although I've never heard of pizza Gyoza back in Tokyo.
April: That's because Murakami invented it. You should try one.
Karai: That sounds great. You should try some of mine.
April: Done.
[Karai placed her coin down. Murakami looks and nods.]
Murakami: Hai.
Karai: What's your name?
April: I'm April.
Karai: My name's Harmony.
[At the underwater world, The sea monster started to see the sub but they distract it by firing a laser. The creature chases after it. ]
Kraang: Kraang should increase the molecular conversion of that which is water.
Leo: We gotta get in there before that sea monster comes back.
Mikey: How are we gonna get past those guards?
Leo: We make them come to us.
[The submarine began to grab a rock with its mouth and used it as a blockage blocking the opening.]
Kraang: Kraang, there is a blockage which is preventing the flow of that which has been blocked.
Kraang 2: Kraang must come with Kraang to dislodge the blockage that needs dislodging.
[The hatch opens up.]
Kraang: But water gives Kraang's membrane wrinkly fingers.
[The turtles enter inside the water dome.]
Leo: We're in.
Raph: And that thing is back. How are we gonna get out of here?
Leo: We'll worry about that later. Right now, we've got bigger fish to fry.
Mikey: I don't think we're gonna find a bigger fish than that. What? Come on, that was good. You gotta give me that one.
[Back to April.]
April: So what brings you to New York?
Karai: I'm with my dad. He's here trying to close an old deal.
April: Oh. What does he do?
Karai: He's in kitchen utensils. Knives, mostly.
[Murakami serves them gyoza and soup.]
Karai: Itadakimasu.
April: "Itatakimas".
Karai: All right, let's see what these pizza potstickers are all about. Mm. Best dumpling ever!
April: I know, right?
Karai: Now you try mine.
April: What is it?
Karai: Suppon nabe. Turtle soup.
April: [suddenly recognizes] Karai.
Karai: In person.
[April begins to step away from Karai.]
April: Uh, I gotta go.
[She starts to leave but Karai held her back]
Karai: I was thinking you'd come with me, April O'Neil. My father would love to meet you.
April: Let go of me!
[Murakami tosses the soup onto Karai as April escapes.]
Murakami: Oh! I am so sorry!
[Karai exits outside and sees April running off. April began to take out her T-phone. Meanwhile the turtles sneak from above.]
Leo: Okay, we have to be quiet.
Donnie: Do you have to say that every time? We're ninjas. We know how to be quiet.
[Donnie's phone rang]
Mikey: Ooh, that is embarrassing.
[The turtles dodge the lasers.]
Donnie: April, hi! It's not a great time!
April: Donnie, Karai's after me!
Donnie: What? ]Leo pins Donnie down] Karai's after April. We gotta help her!
Leo: And who's gonna help us?
Donnie: April, I'm sorry. We can't get there. But don't you worry. You just stay calm [screaming] AND RUN! RUN FOR YOUR LIFE!
[April looked back as Karai chased her.]
April: Is that pizza for O'Neil?
Pizza guy: Nah, it's for, um.. Hey! What are you doing?
[April grabs the motorcycle and drives off.]
April: I'll bring it back! I promise!
[Karai gets into her motorcycle and chases after April. April spots and goes around the corner. and tried to invade Karai. She turned to the alley and quickly dodged a truck.]
Leo: Donnie, focus! April can take care of herself.
Donnie: Against Karai? Are you kidding? I've gotta help her!
Leo: You're not gonna be much help if you get blasted in the head.
Donnie: Good point.
[He whacks a Kraang into the others while the others destroyed the Kraang.]
Mikey: That's a twofer. Thank you, and thank you.
[The Kraang get up but Raph stabs them]
Mikey: And thank you.
Raph: How many times have I told you? No celebrating till the fight is over!
MIkey: How many times have I told you, I assumed it was over?
Donnie: Children, children! We have to go!
Leo: Um, have you forgotten about a little something called completing the mission?
Donnie: But April's in danger!
Raph: If we leave now, the Kraang will poison everyone in New York, which, last time I check, includes April.
Leo: Think, Donnie. How do we take this place out?
Donnie: Well, uh, the chemical is highly explosive.
Mikey: How do you know that?
Donnie: Partly because it has a hydrocarbon on its outer ring, and partly because of that sign. Raph, do you think you can get this blaster open for me?
Raph: With pleasure.
Donnie: But before you do, be careful you don't..
[Raph easily stabs the blaster.]
Donnie: Oh, good. We're still alive. Now I'll short out the power supply and leave it by the chemical tanks. It'll overheat, and the whole place will go boom!
Mikey: All right! Victory dance!
Leo Donnie and Raph: Mikey!
[Screen cracks]
Mikey: Or maybe later.
[Donnie gets to the top with Raph and Leo's help. He jams the gun in.]
Donnie: There, in about 90 seconds, this whole place is gonna blow.
Leo: All right, let's move!
Donnie: April, what's your status?
April: Could be better!
Donnie: Okay, we're on our way. We'll be there soon.
[The sea monster appears scaring the turtles who cuddle up.]
Donnie: Actually, it might be a slight delay.
[They dodged the monster's mouth. The monster tried to eat Raph but Donnie saved him.]
Mikey: Gotcha!
Donnie: We've only got thirty seconds before that blaster explodes!
Leo: Uh, guys, any ideas?
Donnie: Well, let's see. We're cornered by an amphibious sea monster in an underwater base that's about to blow up. I'm out.
[Mikey started to ride the sea monster and closed the hatch around its neck.]
Mikey: Whoa! Whoa! Whoa! That was fun!
Donnie: Mikey, that victory dance better not last more than four seconds!
[They escape as the dome explodes.]
Raph: That wasn't such a chore, now, was it?
Donnie: Great, now we can get back to Apr- Are you kidding me?!
[The sea monster started to go after them. Meanwhile, Karai ran on foot as April continued to drive the motorcycle. She started to throw her ninja stars as she climbed down the fire escape.]
Leo: Donnie, can you make this thing go faster?
Donnie: Of course I can.
[He activates the wrong button which causes the thrusters to explode.]
Mikey: Wow, that is fast.
Donnie: Pedal faster!
Mikey: Feelin' the burn! Go, go, go!
[The sea monster grabbed the submarine, wrapping it around.]
Donnie: [very frightened] That's it. It's got us. We're gonna die!
[For a moment, Donnie opens his eyes. The sea monster was not attacking them. Their faces were stunned. Knowing that the sea monster was in love with the sub, they groan in disgust.]
Mikey: Hey, we're not that kind of sub!
[Leo activates the water smoke bombs and leaves the sea monster. Karai took off her helmet as April started to charge at her.]
Karai: You've got guts. Let's see if I can pound that out of you.
[April takes out her tessen.]
Karai: A tessen? Beautiful. Unassuming but very powerful. In the right hands.
[April starts to attack but Karai dislodges her fan. April punched her cheek.]
Karai: Good one.
April: Glad you enjoyed it.
Karai: Now it's my turn.
[She kicks April. April struggles to fight back but she falls down and gets up.]
Karai: What makes you so special? You're the center of an alien conspiracy, protected by mutants and trained by a great ninja master. Why?
[April fights back.]
April: I don't know! I'm flunking trig. My friends are mutants. Aliens got my dad. And I lost my mother!
[This word hits Karai. She becomes flabbergasted that April lost her mother (realizes that she has something in common with April, because it is heavily implied that she lost hers).]
Karai:[shocked] What? You lost your mother?
Splinter: The key is to unbalance your opponent.
[April threw her aside and crashed into the stands of the subway station.]
April: Not bad for a nobody.
[She leaves as Karai limps toward.]
[Meanwhile. the submarine arrives as the turtles exit out.]
Donnie: Come on, April. Come on, April!
April: Hey, Donnie.
Donnie: April! You're okay! You hear that, guys? My sweet princess is alive! Did I mute that?
April: Let's agree that you did.
Donnie: You got it.
[Later on,]
April: And when her guard was down, I flipped her down the subway steps and bolted.
Donnie: That is awesome!
Mikey: You rock!
Raph: Kick butt!
Splinter: Impressive, April. You used your training well, and you fulfilled the most important goal of the ninja: To come home alive.
April: Thank you, sensei. Looks like I can take care of myself after all.
Splinter: Yes. And no. Karai may have failed this time, but if Shredder wants you, he will stop at nothing to find you. And with the Kraang after you as well, the wisest decision is for you to remain here in the sewer with us.
April: What?
Donnie:[joyful] Oh, that's great! I mean, oh, that's horrible. That, you know, your life as you know it is is over and, um.. I'll shut up now.
April: I can't stay down here. I mean, what about school, my friends, everything?
Leo: April, Master Splinter's right. Until we stop Shredder and the Kraang, this is the only place you're safe.
April: So once we stop them, I can have my life back?
Leo: Yes.
[April realizes she will return to her old life after they defeat Shredder, Foot Clan and the Kraang once and for all or retrieve her father back in safety. April agrees.]
April: [determined] Let's get started.
[Episode ends.]
