Melt the green candy melts in a microwave or double boiler according to package directions until they are fully melted.

Push the lollipop sticks into the marshmallows then dip the marshmallows into the melted candy, turning to cover them completely. Stand the marshmallows upright in a glass filled with uncooked rice or oatmeal and place the glass in the fridge until the chocolate has cooled and hardened slightly, about 5 minutes.

Melt the chocolate chips in a microwave or double boiler until smooth. Dip the tops of each of the coated marshmallows in the chocolate to form the hair, and using a toothpick, drag the chocolate down toward the base of the marshmallow to form spikes of hair. Return the marshmallows to the fridge until the chocolate has hardened, about 5 minutes.

Break the ends off of the pretzel rods to form the small (about 1/8-inch) "bolts" for Frankenstein's neck. Carefully push one piece of pretzel into each side of the marshmallow about 1/3 of the way from the bottom.

Using a toothpick and the remaining melted chocolate, dab two small dots of chocolate onto each marshmallow and press on the candy eyeballs.

Using the black edible marker, draw on a mouth, and then using the red edible marker, draw on a laceration on Frankenstein's forehead. Enjoy the marshmallow pops immediately or store them in an air-tight contained in the fridge until ready to serve.

Candy melts can be found at most bakeware stores. Do not substitute white chocolate and green food coloring for the candy melts, as most food colorings are water-based and will cause the chocolate to seize.
