Ernie, Mr Rails, Millie, the trains, Shrek and Donkey arrive at the tower

This is how Ernie, Mr Rails, Millie, the trains, Shrek and Donkey arrive at the castle goes in Underground Ernie Meets Shrek.

[The heroes climb a mountain side]

Donkey: Oh, Shrek. Did you do that?

Bakerloo: Oh, excuse you!

Donkey: Man, you gotta warn someone before you just crack one off. My mouth was open and everything.

Shrek: Believe me, Donkey. But, if it was me, you'd be dead. [sniffs] It's brimstone. We must be getting close. [moves on]

Victoria: I haven't smelled a smell like that since Circle had onions in her carriages.

Ernie: You couldn't be more right, Victoria.

Donkey: Yeah, right, brimstone. Don't be talking about it's the brimstone. I know what I smell. It wasn't no brimstone. It didn't come off no stone neither.

[They climb up a ridge and peek over the edge towards a castle surrounded by lava and clouds swirling near its tallest turret with a bridge leading to it]

Shrek: Sure, it's big enough. But, look at the location. [laughs]

[He climbs over the edge and climbs down]

Donkey: Umm, Shrek? Remember what you said that ogres have layers?

Shrek: Oh, aye.

Donkey: Well, I have a confession to make. Uh. Donkeys don't have layers. I mean, we wear our fear right here on our sleeves.

Bakerloo: Wait a second. Donkeys do not have sleeves.

Donkey: You know what I mean.

Jubilee: You can't tell us you're afraid of heights.

Donkey: Uhh, no. It's just that I’m not comfortable with being on a rickety bridge over a boiling lake of lava!

Shrek: Look, Donkey. We're right here beside you for emotional support. We shall tackle this thing together one little baby step at a time.

Donkey: Really?

Hammersmith: We're behind you all the way.

Donkey: Okay, that makes me feel so much better.

Ernie: Keep going and don't look down.

Donkey: Okay, don't look down. Don't look down. Don't look down. Keep on moving. Don't look down.

[Donkey steps on a board too hard and it breaks off, causing him to look down]

Donkey: [gasps] Guys. I'm looking down! [screams and turns to the others] Oh, Gosh, I can't do this! Just let me off, please!

Ernie: But, we're halfway already.

Donkey: But I know that half is safe!

City (Underground Ernie): And as a matter of fact, I think finding a safer way in is the best option!

Shrek: Okay, fine. We don't have time for this. You go back.

Victoria: And, City, young man, I suggest you stop your whining and suck in that gut.

Donkey: Guys, no! Wait!

[Ernie and Shrek shake the bridge as they move]

Donkey: Aaahh!! Don't do that!

Ernie: Oh. I am sorry, Donkey. Do what? Oh. [shakes the bridge] This?

Donkey: Yes, That!

Shrek: Yes? Yes, do it.

Ernie: Ok.

[They shake the bridge as they keep moving]

Bakerloo: Ernie, I highly think shaking the bridge is necessary!

Donkey: [screams] No, guys! No! Stop it!

Ernie: You said do it! We're doing it!

Donkey: I'm gonna die. I'm gonna die. Shrek, I'm gonna die.

[He's already on the other side]

Donkey: Oh.

Shrek: That'll do, Donkey. That'll do.

[The trains, Ernie, Mr Rails, Millie and Shrek walk past him]

Donkey: Cool.

Bakerloo: So, Where is that fire-breathing lizard anyway.

Shrek: Inside, waiting for us to rescue her.

Donkey: [chuckles] He was talkin' about the dragon, Shrek.

[Later, the trains, Ernie, Mr Rails, Millie, Donkey and Shrek walk through the castle]

Donkey: You afraid?

City: I am a little. This castle's already giving me the creeps.

Shrek: No. But, shh.

Donkey: Oh, good. Me neither.

[Shrek and the others move on. Donkey stops for a while then rejoins them]

Donkey: 'Cause there's nothin' wrong with bein' afraid. Fear's a sensible response to an unfamiliar situation. Unfamiliar dangerous situation, I might add. With a dragon that breathes fire and eats knights and breathes fire, it sure doesn't mean you're a coward if you're a little scared. I sure as heck ain't no coward. I know that.

[He bumps into some armor and gets a helmet on his head. The knight's head falls off, causing Donkey to jump in fright]

Ernie: Keep it down! The dragon will hear!

Shrek: Donkey. Two things. Ok. [touches one finger] Shut. [touches another finger] Up. Now, go over there and see if you can find any stairs.

Donkey: Stairs? I thought we was lookin' for the princess.

Shrek: The princess will be up the stairs in the highest room in the tallest tower.

Bakerloo: What makes you so sure?

Shrek: I read it in a book once.

Donkey: Cool. You handle the dragon. I'll handle the
