The skull face on the right comes from the plastic skull attached to a candy container at the far left of the photo below. It giggles evilly and screams when jostled in any way and the eyes flash red. The candy contained the red dye called Carmine, which is made from crushed beetles and is thus not vegan.
The various doll face molds are from this lovely object I bought at Good Will. It has a Disney stamp on it, but I don't recognize the character. It had long fake eyelashes which came off when I made the mold. I made a mold of the eyelash itself and the mold survived the bisque kiln, but somehow I lost it while carrying it to my shelf.
