I can see the sign in my head, but #3 just isn't coming to me. For #4, I'm going to guess they're both sponsored by Pepsi. Wasn't there a shuttle coaster over 200' tall in Japan? "Moonsault Scramble" or something to that effect comes to mind. As for Tremors, I think it's got four underground tunnels. I remember hearing about some interesting effect on the ride, but I can't remember exactly what it is.
