Rudolph's red nose was a gift from Santa himself. Santa noticed that Rudolph was a bit shy and timid, so he wanted to give him a special feature that would make him stand out from the other reindeer. So he used his magic to give Rudolph a shiny red nose that glowed brighter than any other reindeer's. It was Rudolph's unique nose that made him the lead reindeer and the most famous reindeer of all.
