Bake the cupcakes according to the directions on your package and let them cool completely.

Frost the cupcakes by spreading chocolate frosting out over each cupcake with a butter knife or icing spatula. Don't worry about perfection here.

Break the pretzels apart and use them to make legs. Break the pretzels apart so you have the curved outer part of the pretzel in a c shape. It's ok if they aren't perfect. Once you have the pretzels all broken apart, push 4 into one side of the cupcake to form legs and 4 into the opposite side. Repeat with all the cupcakes.

Decorate the faces. Put the eyeballs on the face of the spider. Then draw a smile for the mouth. Cut the white part off of candy corn and press that into the mouth icing as fangs. Then enjoy!
