I have been to a Belive it or Not theme park... well more like a theme 'house' in Florida. It is a very bizzare place if you haven't visited. The house itself has been built upside-down to show that a hurricane has removed it from the foundations, and it has landed on its roof. Most things inside are also upside down.
There is also another where part of the house has sunk into the ground. All very clever in my opinion
My little brother has a Ripley's Believe it or Not book, it's green and purple I think, with one of those covers what changes when you tilt the book. I think the picture is of this woman what has poppy eyes.
