Here is how Here comes the Calvary goes in Fantasyland Rescue.
In the tunnel.
Casey Jr.: Now, What'll we do!?
Princess Yuna: I'm not strong enough to use my magic yet.
Dusty Crophopper: I think I have an idea. Duck, Try to use your whistle!
Duck: Good idea, Dusty!
Train: Let's all do it together!
Casey Jr.: (whistled)
Princess Yuna: That's loud enough for anyone to hear us!
Jones the Steam: Keep whistling, Ivor!
Ivor: (whistled) Come on, Everyone! Start whistling!
Greendale Rocket: (whistled)
Tigatron: Did you hear that?
Airazor: I think so.
Tigatron: Look! It's coming from that tunnel over there!
Airazor: I hears some whistling!
Tigatron: One of them must be Duck!
Airazor: It is Duck!
Tigatron: Come on, We must go and get help!
At Brendam Docks.
Percy: Any luck yet?
Loco: Still no sign of any of them.
Percy: I hope they're okay.
Cranky: We better keep our hopes up.
Percy saw something.
Percy: Cranky! Salty! Porter! Gator! Loco! Look! That must be the tunnel to Fantasyland up there.
Cranky: That's impossible!
Eliza: Mommy? Daddy? Do you think Yuna, Dusty and Duck could be in Fantasyland?
James: Maybe, Eliza.
Molly: We won't know for sure.
Eliza: How long has this tunnel be blocked?
Sir Topham Hatt: It's been blocked for years.
Princess Celestia: Let's hope they're in good hands.
Princess Luna: I hope Yuna is alright.
Sir Topham Hatt: Let's keep our hopes up for their safety.
Gator: Percy, Look!
Percy: It's Tigatron and Airazor!
Tigatron: We found the tunnel!
Airazor: It leads to Fantasyland! And Yuna, Dusty and Duck are inside that tunnel to Fantasyland!
Percy: I can't believe it!
Gator: Thank Goodness!
Percy: We must find a way to dig that tunnel!
Gator: But how!?
Thomas: I have an idea!
