Put the white chocolate chips into a microwave-safe bowl. Microwave at 15-second intervals, stirring in between to ensure the chocolate doesn’t burn. It will take only about 30-45 seconds.
Dip the tops of the cookies in the chocolate to coat, then set them on a wire rack.
Add the candy eyes before the chocolate cools.
After the chocolate has cooled and set, you can drizzle on the chocolate bandages. To do this, melt the chocolate again in the microwave, let it cool for a second, then scoop it into a plastic bag.
Cut a very small corner off the bag and squeeze the chocolate back and forth over the cookies to resemble mummy rags. Let the chocolate set fully before serving.
