Here is how Princess Yuna and her friends freed the Prehistoric Animals in The Lost World: Genesis Park.
Later that night.
Radcliffe: You know Professor Mosquito Amber had a dream, Creating all Extinct Animals. Either Prehistoric, Others from hundreds of years ago. Manehattan is a perfect site, To make my own captivity.
With the foals and close friends.
Alexis: That's why Grandpa was in a hurry for us to come here, he knew they were coming.
Jim: What's the plan, Yuna?
Princess Yuna: We need to free the animals
Stith: I know something Professor Amber did sent a backup plan.
Oh: Backup plan. What backup plan?
IO: (takes out a pair of chain cutter) Me, Stith, Skyla and the Royal Crusaders.
Radcliffe: As you can see, Gentlemen. My uncle has started his plan. So now, It's my turn.
IO, Stith, Skyla, the Royal Crusaders and come in.
Sweetie Heart: Wow. An Elasmotherium.
Princess Skyla: And look. Scutosaurus.
Armor Bride: (approached to the Velociraptors cage and a Smilodons cage) I hope they can be tamed.
Radcliffe: It will be a great pleasure to present all the extinct animals for our finest tourist.
Skyla, The Royal Crusaders, IO and Stith are opening the cages, still continuing freeing the Prehistoric Animals and till they freed a Triceratops, Torosaurus and other horned dinosaurs and prehistoric rhinos.
Radcliffe: Making my own Prehistoric Zoo in Manehattan will be the greatest....
Just then, the Triceratops busted through the tent.
Triceratops: (grunts and charged at one of the trucks)
Velociraptors: (gathered together)
The several Prehistoric Animals destroying half the camp.
Princess Skyla: (hears the infant Carnotaurus) I hear something. Come on!
Radcliffe: It appears we're not alone on this island. Search everywhere!
Poacher: Yes, Sir.
Armor Bride: (is carrying the infant Carnotaurus) It sure is heavy.
Scander: I got your back, Sis. (helping Armor Bride)
Armor Bride: He has a broken leg! We need him to get back to the RV!
Britney Sweet: Right behind you, Armor Bride.
IO: (opens the 4x4 jeep's door)
With the others.
Princess Yuna: Okay, test it, Wilbur.
Wilbur the Albatross: (testing the High Hide Elevator) It works!
Then, the 4x4 Jeep drove by.
Orville: What the heck is that?
Princess Yuna: A baby Carnotaurus and It's got a broken leg.
Then, there was a roar from Carnotaurus.
Princess Yuna: This is not good.
Sunbeam: Where are you going, Yuna?
Princess Yuna rushed to the RV and warned the others.
