Frogzards are the result of an ill-fated experiment of the combination of reptile and amphibian. They are carnivarous, are tamed for work (such as the Rayzard is used by many dwarf miners) or used in battle. Or if you're crazy enough, a pet. Frogzards have many diffent element types such as water, fire, darkness-their elements are recognizable by their color.
I think this is quite a good creation. It is actually a very good rendition of the creatures from AdventureQuest. However, they are somewhat unatractive in design. I'm afraid the 'zards don't cross over into LEGO very well. Because of your acurate rendition, I give you 4 out of 5.
