I used the secret LEGO Universe mode on LEGO Digital Designer (which was removed last I heard) to rebuild the Crystal King. I was able to change the colors on the crystal parts of the monster, and make look as though there were different types of monsters all the size of the Crystal King. Now Boulderax, Meltrox, Glaciator, and Firox have their own kings, too.
