I'm 22 about to be 23 in the next few days. When I was a kid there used to be this kid carnival(for lack of a better term or actual name) I used to go to. Every year this mobile Radio station replica would be there handing out gold coins with a picture of it on it. It's from a movie about Atlantis and supposedly it was kept at the Atlantis waterpark. It's a massive amphibious(in the movie) 6wheeled vehicle that I think is either purple or blue. I Can't think of the name of it. I was trying to find a picture of it earlier.
