On Christmas Eve, Nathan put out reindeer food for Rudolph. He made it in school and was excited to put it out in the yard. Reindeer food is simply oats and craft sprinkles. The oats for the reindeer to eat and the sparkly sprinkles to shine in the moonlight and light the way to your house. Nathan went around the house to the chimney and sprinkled the baggie of reindeer food on the ground.
