Place the white chocolate chips in a bowl and melt them in the microwave for about 1 minute. Repeat this process in 20 second intervals until all the chocolate is melted.
Cover the pretzel rods with the melted white chocolate leaving about 3 inches (7.5 cm) at one of the ends for holding. Hold them upside down to let the extra white chocolate drip off as much as possible and place them on parchment paper. Immediately place two candy eyeballs for the eyes and one mini milk chocolate chip for the mouth. If you don't have candy eyeballs, you can use two mini chocolate chips for the eyes. You can also melt regular milk chocolate chips to make the eyes and the mouth.
