Humpty Falls by J.E.Moores.

Stages to make this toy:

1. terra cotta clay
2. bisque fire
3. glaze fire
4. silicone mold
5. hand cast white plastic
6. paint to bring out details

I use Smooth-on.com products. Rebound 25 brush-on silicone mold, with Smoothcast 300 (opaque) or 325 (clear) polyurethane plastic. I learned most of what I know about casting resin toys from the smooth-on youtube videos.
