Press a popsicle stick in the middle of each marshmallow, until it goes all the way to the other side, so it is secure at the top of the stick.
Place the chopped chocolate in a microwave safe bowl (reserving a handful) and microwave on medium in 30 second increments, stirring in between, until melted. Throw in the remaining chopped chocolate and stir until completely smooth. Adding the extra chocolate at the end sort-of tempers the chocolate without any effort, so it doesn't dry cloudy.
Spoon the melted chocolate over each marshmallow (or dip) rotating the stick to coat completely. Tap the pop on the edge of the bowl to remove excess chocolate. (Remelt the chocolate as needed if it starts to dry.)
While the chocolate is still loose decorate the Chocolate Covered Marshmallow Pops: Sprinkle with crushed graham crackers for S'mores Pops. Decorate with sprinkles, candy eyes, and nose for Monster Pops. Pipe with melted white chocolate and add eyes for Mummy Pops. Or add candy pumpkins and sprinkle with green sprinkles for Pumpkin Patch Pops.
Place in mini muffin papers or in a piece of styrofoam to dry. Once dry, store in an air-tight container for up to 2 weeks.
