Start by sorting the M&M's® candies by individual colors. Placing each color into a small bowl is helpful. In a microwave safe bowl, melt the white candy melts according to package directions.
Dip the tip of the paper straws into the melted candy coating, and insert into the end of the marshmallows. This will help the straws stay secure.Using a toothpick, place a small amount of the white candy coating on the bottom side of two similar color M&M's®, and place closely together on the marshmallow, making the mummies eyes.
Place the remaining candy coating into a resealable plastic bag (or disposable candy piping bag), and cut off the tip/corner of the bag, making a small hole. Using long strokes, coat the marshmallows with strips of white coating, creating the look of the mummy.
