The original dragon came as a gift from my sister and brother-in-law. First I just wanted to change its claws; they just did not seem right to me. But things got out of hand (hmm, recurring theme, it seems). I modified it with some Bionicle LEGO and other parts to fit my needs. Now it fetches the newspaper for me, keeps burglars out, and cooks up a delicious lasagna :-S
I like dragons, and what you've done is really cool. You could enter it in the hallowe'en competition on http://brickiwiki.wetpaint.com/ and be in with a good chance of winning $50 Amazon gift certificate!
