Place the chocolate chips in a microwave-safe bowl. Microwave for 60 seconds on high. Stir the chocolate quickly until smooth. If you need, microwave for an additional 15 seconds, until all melted.
Dip the pretzel in the melted chocolate, holding it with a stick or a small fork. Coat evenly with chocolate. Lay the pretzels down on a microwave-safe plate lined with parchment or wax paper.
Add two mini marshmallows for the eyes. Microwave for about 10 (no more than 15) seconds. The marshmallows should inflate slightly.
Quickly place one mini chocolate morsel in the middle of each marshmallow. Push the morsels down with the tip of your stick. You should work quickly while the marshmallows are still soft
Let the chocolate set before removing from the wax paper. Freeze for ten minutes, or refrigerate for at about 20 minutes. Once hardened, you can remove the pretzel from the paper.
