I made this mask by mixing latex with flour and using that latex paste to build up the face. For the eyes I used old christmas ornaments which I spraypainted black. The teeth are made of polymorph plastic and I painted everything with alcohol based paints.
To finish off the look, I put lubricant on the teeth and inner mouth to make it look wet and shiny.
The legs are made of spraypainted newspaper and cotton balls attached to a hairband.
