dinosaur girl

You were having a normal day and decided to go camping! You were having a great time until suddenly a hole opened up in the side of a hill and some random girl ran out of it! You looked in the cave and saw a bunch of dinosaurs! You know you should probably run away and not get involved in any of this, but you dont want to just leave knowing nothing! You see the girl run over to you.. Hey you! What are you doing here? What is this place? What kind of creature even are you??
