Penny: (hears Luigi sneeze) What's the matter?
Luigi: (sneezes) I think I'm allergic to grass. Penny: It's a good thing I like climbing things. (hears the train sounds) What's that noise?
Luigi: The trains, I told you they talk. We'll just hear and find out what they are saying. (the trains puff past as Lightning MacQueen heads by)
Casey Junior: Hey, guys, look, it's Mario. We've found him. (the coaches and caboose realize it turns out to be Luigi) Oh, dear, it's Luigi.
Penny: Luigi, look!
Junior: It's Casey Junior! Casey! Now don't look so surprised I know you haven't seen me since…
Casey Junior: you've stuffed birthday parties into the wheels.
Luigi: We've had a laugh.
Casey Junior: You did.
Penny: You're speaking to each other.
Luigi: Penny. Casey. Casey. Penny. Now where's my cousin?
Casey Junior: Hello, Penny, welcome to Fantasyland.
Junior: Come on, Penny, I'm very home on trains.
Casey Junior: Hey, guys, I'll send Tootle off to fetch you.
Casey Junior's Coaches and Caboose: We've heard that one before!
Penny: What's wrong?
Luigi: Travel sickness. (Casey approaches the windmill and sees Mario)
Penny: What's that shining at the windmill. (Thomas blows Casey's whistle and Emily stokes Casey's fire)
Luigi: No fear, Penny, it's my cousin.
Casey Junior: Mario! Mario!
Mario: Casey Junior!
Casey Junior: Thank throttles your safe!
Luigi: Come on, Penny. Hey, cous, what's up?
Mario: I think so, but have landed here, and have escaped a heavy metal monster. So where have you been?
Casey Junior: Well, is your sparkle back, Mario?
Mario: Nah, it isn't, but I do know the clue. (tries to remember, but fails)
Casey Junior: Bother!
Luigi: Hey, cous, if we get more dust when running out, you can go back home and I can go to the beach.
Mario: Luigi, I want you to listen to me, and I want to listen to me very carefully.
Casey Junior: Uh-oh.
Luigi: (makes some voice lines to Mickey Mouse)
Mario: Yes, Mickey, sir. No, he just wanted to be friendly. No, he's not a dog. Well, let's just say he's a dog, and he'd have a good trainer. No, nothing to worry about, Mickey. Goodbye, Sir.
Luigi: Mario, this is Penny, who is staying with Uncle Gadget.
Mario: Hello, Penny.
Mario: What do you think you're doing up there? Will you come down?!! It's too windy, don't you know!?!
Luigi: This is just like the funfair. Give us two seconds.
Mario: Two seconds is it all takes for you to land in trouble. (Luigi has too much fun that the wind blows and sends him flying out of Mario, Penny, Casey, Thomas, and Emily's reach, when he lands on Cerberus's roof)
Cerberus: Ah, twinkle toes, Luigi!
Luigi: Darn, I've lost my beach bag!
Cerberus: You won't be doing any surfing up here, Mama Luigi.
Luigi: Really? Watch me.
Cerberus: Hang on tight, moon doggy.
Luigi: (cheers for fun)
Casey Junior: Oh no! Cerberus has hijacked him!
Emily: What will happen to Luigi now?
Thomas: Well, we usually are pretty good at getting ourselves out of trouble, and I don't know what eventually means, but it sounds longer than ever before.
Inspector Gadget: Where's Penny?
Pinocchio: I wish I knew. I'm sorry, Uncle Gadget. She wasn't at the station when I went back for her.
Tootle: I'm brave, I'm brave, Casey says, I'm brave. So I'm brave. It's not so easy being brave. Shiver my pistons! There's Samson and the Train. Oh, they've find the buffers. Oh no. Now what will ever happen? (gasps as he hears strange things as a woolly hayball rolls by) I thought it was something.
Samson: Ah, these must be the buffers that we are looking for.
The Train: Uh, are we supposed to go through them?
Samson and The Train: Oh, not me, you. No, not me, you. This is a job for the boss. (both scream) We'll tell him tomorrow. - Yeah, tomorrow's good.
Tootle: I'd better hurry back to warn Casey.
Mario: (while playing cards with Penny, Thomas, and Emily) I was doing my best to keep Penny cheerful. I knew she was worried about being late for her uncle.
Penny: Mario, I was supposed to be back by sunset.
Mario: You know, Penny, perhaps your uncle can guess where you are.
Penny: He can?
Mario: Maybe. Because I think he's been here himself, long ago. And if he can help, I do wish he'd hurry. I haven't told Junior this, but soon he'll grow as weak as I am.
Penny: Luigi said there used to be an engine that traveled on the magic railroad. And if only we could find that, we could still head back to Shining Time.
Mario: Oh, that engine disappeared... never to be seen or heard from again.
Penny: I have to tell you something, Mario. I've heard a train whistle, and it sounded like it came from the mountain.
Mario: (surprised) Mountain?! (smiles) I just remembered another part of the clue! Stoke up the magic in the mountain (Casey is shocked, but smiling) and the Bahia Train will smile! We need more information, Penny. And I know that your uncle can help. If he would just believe he that he could.
Pinocchio: She can whistle. I've heard her.
Inspector Gadget: Yeah. So have I. It's because she's magic.
Pinocchio: This must be the map before the magic railroad. But,... the railroad's energy has faded away. I sensed when we were out riding. Penny and I were travelling on the ground above it.
Inspector Gadget: The railroad needs Bahia Train. And I don't know her special steam. And I need to know it or never.
Pinocchio: Because of Penny?
Inspector Gadget: Yes, because of Penny.
Tootle: So, Casey, we must get Penny back to her uncle, before Cerberus gets rid of the railway.
Casey Junior: But how can Penny go without gold dust.
Mario: Only in the lost engine. Unless...
Casey Junior: Yes, sir?
Mario: Casey, will you and Tootle take Penny?
Tootle: Through the buffers? But what if we go on the railway and our wheels don't work?
Tootle: And cold?
Mario: It will be for a while?
Casey Junior: And how can we get back again?
Mario: Because you two are both really useful engines, who will find some ways.
