Roll a 1 mm ball of black flower paste to form a sausage. Cut it in half. These will be the eyebrows.
Roll two 7 mm balls of grey flower paste to form two sausages that taper towards one end. Use the scalpel to cut the ends which will border with the head. Stick the horns on the top of the head.
Form five tiny sausages that taper towards both ends (you will need a 7 mm ball of white flower paste) and stick them on the top of the head to make the hair.
