Rudolph is a fictional reindeer known for his bright red nose. He is often depicted as the ninth reindeer in Santa Claus's team, guiding the sleigh through foggy weather. The character first appeared in a 1939 booklet written by Robert L. May and later became popular through the song "Rudolph the Red-Nosed Reindeer." Rudolph's story emphasizes themes of acceptance and individuality. Initially shunned by other reindeer due to his unusual nose, he ultimately becomes a hero by helping Santa deliver gifts on Christmas Eve. This tale has made Rudolph a beloved symbol of the holiday season.
