To make reindeer food for Christmas, you'll need a handful of oats, a sprinkle of glitter, and a dash of Christmas spirit. Mix the ingredients together in a bowl, and then spread the mixture on your lawn or sidewalk. The glitter will attract the reindeer, and the oats will provide a tasty snack for them. Just be sure to keep the mixture away from any pets or other animals, as they might mistake it for their own food.
