Man, that was awsome! I love how the missles push the Garden down before they blow. I already knew there was a scene where it blew up because it was shown on an FFVIII music video I had.

Another 'secret' movie scene can be found by talking to Laguna in the Presidential Palace in Esthar on the 3rd disc. It shows 3 or 4 Ragnarok ships flying Adels tomb up into space. It's rather awsome too, but alot easier to get than the Garden blowing up.
