Melt chocolate chips in a microwave-safe bowl in 20-second intervals, stirring between each, until smooth.
Pour the melted chocolate over the Coco Pops in a large mixing bowl and stir until evenly coated.
Line a sheet pan with parchment paper and spread the Coco Pops mixture evenly across the pan, pressing down to create a compact layer.
Place the pan in the refrigerator for 30 minutes to chill and set.
Remove the chilled Coco Pops mixture from the fridge and cut it into 15 even squares using a sharp knife.
Melt the green and orange chocolate melts in separate bowls according to the package instructions.
Gently insert a lollipop stick into each square.
Dip each square into the melted chocolate, making some green and some orange, and place the dipped squares on a sheet of parchment paper.
While the candy melts are still soft, decorate the treats with candy eyes, candy corns, and black icing to create monster faces.
Allow the treats to set at room temperature or in the fridge for 30 minutes or until the candy coating hardens.
Once set, your Monster Treats are ready to be served!
