In a large mixing bowl, use a hand mixer to blend cream cheese, blue cheese, sour cream, garlic powder, and chopped nuts until smooth and creamy.

Shape the cheese mixture into a smooth ball resembling Rudolph's head.

Roll the cheese ball gently in chopped nuts to coat it completely.

Use sliced olives for the eyes, a cherry tomato for the nose, and two pretzel sticks as antlers to decorate.

Cover with plastic wrap and refrigerate for at least 2 hours before serving.
