Combine two packages of cream cheese, grated Swiss cheese, Worcestershire sauce, chopped onion and nutmeg in a large bowl.
Using your hands, mix the ingredients until uniformly combined.
Use the cheese mixture to build a "snowman" on your serving tray. The bottom ball will be about the size of a softball.
Use a butter knife to gently spread the whipped cream cheese over your completed snowman. (You don't want him looking like he rolled around in the grass with the green onions showing!)
Use peppercorns to make coal eyes and a mouth.
Cut a small piece of carrot for his nose and give him pretzel stick arms.
Slice the green part of a green onion lengthwise to make a thin scarf and wrap it around his neck.
Serve with assorted crackers and/or apple slices.
