Is this the one (from fading memory) on specific dates or events had a Gonzilla character stomp through the city as a bit of silliness?
I do kind of remember that. Godzilla rises out of the sea and comes ashore and destroys everything including the airport. If I recall correctly, the only way to get Godzilla to leave was to pay money and get a key to remove him. There have been a few sceneries that had some annoying thing that you had to pay to get rid of. Of course an easy way around it would be to take Godzilla's textures and use a giant black alpha and then save it as a dxt1. It would still be there, but would be completely invisible.
Personally, if it was up to me, I would relocate Godzilla's bgl to Cleveland.
There has been several Godzilla sceneries out there, and there is even a flyable Mothra model at Flightsim.
