What's a dragon without horns? I'm not sure but they insist that they have to have them so let's give him some. Start with a small amount of clay and roll it into a cigar styled shape. Next twist it from each end to make it look like a spiral horn. Figure out how long you would like his horns to be. Cut first one end and then lay it next to the other end and make the second cut. They should be roughly the same size.
