Place melting wafers in separate small bowls. Microwave for 15-second intervals, stirring in between, until melted. Insert one end of lollipop sticks into melted green wafers. Push green-colored end of each stick into a marshmallow. Let set 3 minutes.
Dunk marshmallows into orange or purple melted wafers, shaking off any excess coating. Place on a sheet of wax paper, and top with assorted sprinkles or decorations.
To make faces, place melted chocolate in a resealable plastic bag, and snip off one tiny corner. Pipe face designs onto marshmallows.
Remove any decorations or small pieces of candy before giving treats to children 3 years old or younger.
