Santa calls his reindeer using their unique names, which he has carefully chosen to reflect their individual personalities and abilities. Some of Santa's reindeer have names that are based on their physical characteristics or appearance, such as Dasher, Dancer, Prancer, Vixen, Comet, Cupid, Donder, and Blitzen. Other reindeer have names that are more whimsical or descriptive, such as Rudolph, who has a shiny red nose that glows in the dark and helps guide Santa's sleigh on foggy nights.
