Melt 1 bag of candy melt in a microwave safe bowl with shortening for 1.5 minutes. Mix and add more shortening of the candy melt is still too thick.
Dip the tip of each lollipop stick into the candy melt and gently put into the oreo. Let fully dry before coating whole oreo.
Once lollipop stick is dry, place one side of oreo into the candy melt to coat fully, let dry and then do the other side and let dry fully.
While one side of oreo is still wet, place candy eyes onto oreo so they can dry and set.
Once dry, take white icing and make "mummy wrap" design by going from corner to corner in different directions, overlapping to give "wrapped" effect.
Once oreos are fully dry, take black icing to draw on face of Jack Skellington.
