There are eight reindeer pulling Santa's sleigh on Christmas Eve: Dasher, Dancer, Prancer, Vixen, Comet, Cupid, Donner, and Blitzen. In addition, there is a ninth reindeer named Rudolph who has a special role in guiding the sleigh through stormy weather and thick clouds. Together, these nine reindeer form a formidable team that allows Santa to deliver presents to children all over the world in one night.
