Melt chocolate melting wafers in a microwaveable safe bowl. Melt in 30 second increments so you don't burn chocolate. You shouldn't need to go over 1 minute and 30 seconds.
Using a fork, dip pretzel in the chocolate and coat.
Remove and add to a cookie sheet with parchment paper or wax paper.
Add the eyes.
If you need to, use a tooth pick to remove some of the chocolate from the chocolate ghost's mouth area.
Let dry and break off any stringy or extra pieces of chocolate. then serve and enjoy!
