The story of Rudolph is most famously told in the animated Christmas special Rudolph the Red-Nosed Reindeer, which premiered in 1964. It’s based on the 1939 story by Robert L. May and the popular song by Johnny Marks. Here’s a summary of the classic tale:

The Story of Rudolph the Red-Nosed Reindeer:
Rudolph is a young reindeer born with an unusual glowing red nose, which makes him stand out from the other reindeer. Unfortunately, this unique trait causes him to be ridiculed and excluded by his peers and even the adults in his community, including Santa’s reindeer team.
Feeling out of place, Rudolph decides to leave the North Pole. Along the way, he meets Hermey, an elf who dreams of being a dentist instead of making toys, and Yukon Cornelius, a quirky prospector searching for silver and gold. Together, they embark on an adventure, eventually arriving at the Island of Misfit Toys, where unwanted toys live.
Meanwhile, back at the North Pole, a fierce snowstorm threatens to cancel Christmas. Santa realizes that Rudolph’s glowing nose could guide his sleigh through the blizzard. Rudolph returns just in time to save the day. With his newfound confidence and acceptance, Rudolph leads Santa’s sleigh, and they distribute toys to children all over the world.
In the end, Rudolph is celebrated for his unique talent, and he helps bring joy to everyone, teaching a lesson about embracing differences and finding one’s place in the world.
