Line a large baking sheet with parchment or wax paper. Put a lollipop stick into each marshmallow from the top down so it goes nearly to the end but doesn’t pierce all the way through.

In a heatproof bowl, melt the candy melts in the microwave at 30 second intervals, stirring each time, until melted and smooth. Add more orange candy coloring for a more vibrant color.

Dip the marshmallows into the melted mixture, coating them evenly all over. Use a small rubber spatula to help spread the coating over the marshmallow then roll the marshmallow on the edge of the bowl to remove some of the excess melted goo and to coat the marshmallow thinly and evenly. Place a 'stem' on top of each pumpkin. Let sit until firm, about 30 minutes.

Melt the chocolate chips in a bowl in the microwave at 30 second intervals, stirring each time, until melted and smooth. Using a toothpick, draw spooky eyes and a scary mouth onto the marshmallow pumpkins. Let set until firm. Alternatively, put a blob of chocolate on the pumpkins and add candy eyeballs.
