Dress up as a Mallard with this green duck face mask. I'd give the structure of this one a C, coloration is a solid B. There are small eyeholes at the sides of the duck's bill so you can see when you're swimming around on Halloween night. Pair this with a brown top, tan pants, and orange shoes. Bonus points if you have a white collar and blue chaps. If more than one of your buddies wants to be a duck, this mask also comes in domestic duckling yellow. You'll be trick-or-treating for duckweed and other aquatic vegetation with the occasional worm or snail.
