Melt chocolate according to package directions and transfer into a piping bag or a plastic ziplock bag with the corner cut off. Pipe melted chocolate into molds and tap the bottom of the molds on counter to settle chocolate and remove air bubbles. Place filled molds in the refrigerator and let set for 15 minutes or longer as needed. Remove skull and bones from the molds and set aside.
