clay project for my daughter

My daughter needs to present a "box report" for her class about the story she read. And there are dragon and sea witch (mermaid maybe?) in the book. We tried the air-dry clay at first but they were all cracked after a day or two. Then we tried the polymer clay (shown in picture). The polymer clay is a better compound to make these little figures and so far they haven't cracked yet. We are going to bake them over the weekend once the stove is free... (from cooking?) Just for your eyes only ~

My son thought the dragons were Dinos... XD
