In a large mixing bowl, combine the cream cheese, shredded cheese, bacon, ranch dressing mix, and chives. Stir until well combined. (If using a stand mixer, fold the bacon and chives in by hand at the end).
Transfer the cheese mixture to a piece of plastic wrap. Use the wrap to form the mixture into an oval shape with a slight point on one end. Wrap with the plastic and refrigerate for a minimum of one hour (or as long as overnight).
Decorate the chilled cheeseball with the pecans to create the hedgehog's spines. Add raisins for eyes and a peppercorn for the nose. Serve immediately. (Note 1)
Store tightly covered in the refrigerator for up to one week.
