Luna Girl: Okay moths, ready to ruin this anniversary?
Luna Girl: Perfect. Go!
Moths: You Hoo!
Moths: (swooping in attack)
(Moths and Snowmugs fighting)
Juliet: Hmm? What does she think she's doing?
Luna Girl: (giggling) This is going to be the best ruin-up ever!
Juliet: (gasps) Why that selfish girl! I better do something about this, and I know just the thing.
Skully: Cold Crackers! FrozenGuard dead ahead.
Romeo: Gee, I guess this is the first time I let someone on my Shark Ship.
Captain Hook: Don't you mean the only time?
Romeo: Don't get all pushy.
Doctor Undergear: My grandson has a good point.
Cubby: Umm. Can just say one thing?
Izzy: Sure Cubby.
Cubby: HIT THE BRAKES!
(Tire screeching sound)
Catboy: Can somebody please tell me, what just happened?
Romeo: Phew! We ran out of gas.
Captain Hook: Oh don't worry. I, the great and highly gifted Captain Hook, has got this under control.
Captain Hook: "No" What?
(Engine starting then vrooming)
(Everyone screaming then oof then screaming)
Romeo: Oof! Hey, I'm okay.
Everyone else: Oof! Hey, we're okay.
Skully: But where's Mini Undergear?
Gekko: I got this. No. No. No. Aha! Here we go.
Izzy: Oh dear. All frozen.
Captain Jake: Don't worry. I'll just heat things up.
Romeo: Brrr! That was c-c-c-cold. Just hope this doesn't get any... (gasps) Juliet!
Mr. Smee: Who's Juliet?
Owlette: Oh she's Romeo's witchy love at first sight.
Doctor Undergear: Wow! That's nice.
Cubby: Well what are we waiting for? Let's go to the party.
10 Minutes Later
Shiverjack: Welcome, me hot-headed enemies! Allow me to show you where the party is.
Gekko: Gee Shiverjack. It was sure nice of you to invite us to FrozenGuard.
Shiverjack: It's the least I can do for you guys. Now who's up to some spaghetti and snowballs?
Romeo: Wow. That crystal is so magnificent. If only I could give to Juliet. (sighs)
Gekko: Looking at something Romeo?
Romeo: Oh. Uhh. Yes, yes. Nothin' out of the ordinary. I was following you guys, until I saw this beautiful crystal and... (gasps) The Heart of Coldness! It's gone. What are we going to do?
Greg: Calm down. We just gotta confess about what has happened.
Romeo: And let everyone think I did it? You've certainly not going to let me do it.
Gekko: Okay, okay. Well I guess there must be another way we can do.
Romeo: You're right. All we have to do is runaway from the party, never return, and everything will go back to normal.
Gekko: No. We can't risk ourselves getting hurt.
Romeo: Fine. Then why don't you think of something?
Gekko: I've got it! We can look if somebody else has the crystal.
Romeo: You know that just might be crazy enough, even I couldn't disagree to it.
25 Minutes Later
Gekko: Well, we've tried all the suspects, but they're all innocent.
Romeo: I know. Looks like the Heart of Coldness will just remain lost.
Gekko: Well I'm not ready to give up yet.
Romeo: Hm. Good luck with that. I'm going to see Juliet.
Gekko: (gasps) That's it!
Romeo: Hey Juliet. Pretty nice party isn't it?
Luna Girl as Juliet: Uhh... Uh yes it certainly is.
Romeo: Huh. That's weird.
Captain Jake: Hi Gekko. What's with the ice cubes?
Gekko: Cause a thief took the Heart of Coldness, and I think I know who.
Romeo: What? Lizard Legs, I told you I didn't took...
Izzy: The Heart of Coldness! It's seeking out the ice cubes!
Romeo: (gasps) Juliet, a thief?
Luna Girl as Juliet: Oh please. I just came here to steal it... (Normal voice) ...so I can put it on everyone's downfall.
Skully: Wow! I didn't know Juliet had two voices.
Romeo: That's not Juliet! That's...
Luna Girl: Ah!
Everyone: Luna Girl?!
Luna Girl: That's right, and now that my cover's blown up, I'll be stealing this. Ta ta!
Romeo: Whoa! Whoa! Whoa!
Luna Girl: Looks like I've got the upper freeze now.
Luna Girl: Oof! Whoa-a-a-a! Aah! What in the world?! I'm stuck!
Romeo: You bet your stuck. I'll take that crystal now, moon-lady.
Luna Girl: Oh, fine.
Romeo: Now how do you reverse this thing?
(Glass breaking sound)
Shiverjack: Yes! You've reversed the power of the Heart of Coldness!
Catboy: Thanks Romeo.
Romeo: No problem. Thank goodness we've the thief, but what was that mysterious rope that grabbed Luna Girl?
Juliet: Oh, Rome.
Romeo: (gasps) Juliet?
Juliet: When I was flying around, I saw someone dressed as myself, and I got suspicious. So I made this iceberg costume, and outwit the thief. Clever huh?
Romeo: Wow that's the most shared genius and a great relief. I knew you weren't a common crook.
Shiverjack: Get out of here, Luna Girl! You are not welcome to FrozenGuard.
Luna Girl: You haven't seen the last of me, Lover-Boy, you too PJ Masks.
Shiverjack: Thank you. Romeo, Lizard-legs, and Juliet for saving Never Land, from becoming a Lunar-mayhem.
Owlette: So now what?
Shiverjack: Now, we dance!
