The worlds biggest park

Here I am going to a secret, a secret that hasn't been told. It is the world's  biggest park and there's a fantastic roller coaster that goes crackle crackle. It goes to Mars and that is why at the start it goes crackle crackle. At the end it goes tap tap that is why it goes crackle, tap with a roller coaster. What is the secret? Is it the park? Yes folks it is time to go back to New Zealand yay!
