All you need is an egg box, black paint, goggly eyes, white paper, glue, ribbon and a paintbrush.
First of all you cut the eggbox in to a block of three, cut two U shapes in the box to make it look like wings. Paint the inside and outside with black paint.
Once dry add the eyes and cut some fangs out of the white paper and stick on. Punch a hole in the top to push though the ribbon. Then hang!
