I'm a firm believer in getting the most out of things you pay good money for or even find in the trash for that matter. This Instructable shows you how to quickly & easily turn an animatronic Santa (working or not) into a Creepy Clown for Halloween. It can be done without permanently* damaging the Santa, so you can use him for both Halloween & Christmas. 2 props for the price of 1 is my idea of getting more bang for your buck!
*Depending on the mask you use, you may have to remove Santa's hat but the hat can be re-attached with either hot glue or Velcro dots.
