Bake Mozzarella Sticks according to package directions.
Meanwhile, break pretzel twists into small pieces to make antlers for each cheese stick. Fill the corner of two small plastic bags with mayonnaise and ketchup. Snip a tiny corner from each.
Cut black olives with a drinking straw to make little eyeballs.
When mozzarella sticks are cooked, insert pretzel antlers and bamboo skewers, if using. Pipe mayonnaise on for eyes and top with black olive circles. Add a ketchup red nose. Serve warm.
While the cheese sticks are in the oven, I also prepare some little plastic bags filled with ketchup and mayo. You only need about a tablespoon in each bag. I snip a tiny corner off each and use the mayo for the eyes and the ketchup for the Rudolph-red noses. I make the little edible eyeballs from black olives. My favorite trick: using a drinking straw to cut olive eyes! Just cut the eyeball with the straw and then blow just a bit to pop it out of the end. Love it!
