Put the white candy melting wafers and the red candy melting wafers in 2 separate small microwave-safe bowls and melt in the microwave in 30 seconds intervals, stirring between each. Fill a piping bag fitted with a small round tip with the melted white candy.
Put the red sanding sugar, white sanding sugar, white nonpareils and pink round sprinkles in 4 separate bowls.
Dip the top third of each cake pop into the melted red candy for the hat. Sprinkle with red sanding sugar and top with a halved marshmallow. Pipe a line of melted white candy around the edge of the hat and sprinkle with white sanding sugar.
Pipe 2 curved lines to form a beard with the melted white candy. With a small paintbrush, lightly dab the curved lines to widen the beard. Place a pink sprinkle on the center of the beard for the nose. Sprinkle the beard white nonpareils. Pipe 2 small dots for the eyes and place a black sprinkle on each dot. Chill in the refrigerator for 10 minutes before serving.
