Ash's Adventures of Rudolph the Red-Nosed Reindeer is the third upcoming Pokémon crossover planned to be made by David Graham (aka BowserMovies1989). It will appear on Google Drive in near future.
Santa Claus's reindeer Donner's wife gives birth to a fawn named Rudolph, but the two are shocked to discover that Rudolph's unusually red nose is capable of glowing. When Santa Claus visits their cave to meet the fawn and sees the glowing nose, he warns Mr. & Mrs. Donner that Rudolph won't be able to pull the sleigh if he continues to carry this trait for the rest of his life. Consequently, Donner tries to conceal Rudolph's nose at first with mud and later a small round cap.
A year later, Rudolph's parents take him out to the reindeer games where Rudolph, along with all of the other young bucks, will be trained to fly and pull Santa's sleigh when they get older. There, Rudolph meets a friendly reindeer named Fireball and they quickly become friends. The pair then sees a group of does including one named Clarice, who seems to love Rudolph. Fireball then encourages Rudolph to speak with her. She thinks he's cute which causes Rudolph to perform a dazzling leap into the air and fly. However, when Rudolph and Fireball engage in celebratory play, the cover pops off Rudolph's nose and unveils his "non-conformity," scaring Fireball and ending their friendship. All of the other yearlings then make fun at Rudolph's nose and he is not allowed to join in any more reindeer games. Clarice, who is not the least bit bothered by Rudolph's secret, catches up with the sulking Rudolph to try to comfort him. Soon after, Clarice's father forbids her to hang around with Rudolph, breaking his heart and runs away. Meanwhile, an elf named Hermey dreams of becoming a dentist rather than making toys. His supervisor is outraged at his persistent disruption with his dentistry studies. Feeling ridiculed and misunderstood, Hermey also decides to run away. Later, Rudolph meets up with Hermey and the pair decide to set off together.
Along the way, they meet a cheerfully and boisterous prospector named Yukon Cornelius, who dreams of discovering silver and gold, before the trio bumps into the Abominable Snow Monster who is attracted to Rudolph's nose. Escaping on an iceberg, they arrive on the Island of Misfit Toys where unwanted toys live with a winged lion named King Moonracer, until he can find homes for them. The king agrees to let them stay for one night in exchange for a promise from Rudolph that as soon as he, Yukon, and Hermey return, they will ask Santa to deliver the Misfit Toys to children who need them. However, Rudolph decides to leave the island alone knowing that his nose will endanger his friends.
Rudolph grows older and drifts from place to place, making and losing friends as he is continually rejected for his glowing nose. Eventually deciding to go home, he returns to his cave to find that his parents, along with Clarice, have left to search for him. Rudolph then sets out to find his family and discovers that they have been captured by the Abominable Snow Monster, who plans to eat them. After a brief fight, Rudolph is knocked unconscious. Fortunately, Hermey and Yukon Cornelius arrive and hatch a rescue plan. Luring the monster out of the cave, the pair knock the Snow Monster unconscious and Hermey extracts his teeth. Rudolph awakens, but he and his family are blocked from their escape by the also awakened beast who blocks the entrance to the cave. Yukon chases the now toothless monster to a cliff, driving him off the edge. Mourning Yukon's loss, Rudolph, the Donners, Clarice, and Hermey nonetheless return home. where everyone apologizes for the way they acted while telling them about their adventure. Santa promises Rudolph that he'll find homes for all the Misfit Toys, the Elf Foreman agrees to let Hermey open his own dentist's office a week after Christmas, and even Donner apologizes to Rudolph for being critical about his nose. Upon celebrating, Yukon returns with a tamed Abominable Snow Monster, now a kinder and gentler monster. However, a huge blizzard blows in which threatens to cancel Santa's flight. While announcing the news to the elves and reindeer, Santa is caught by Rudolph's gleaming nose and decides that its light could cut through the storm. Meanwhile, the Misfit Toys, grieving about being left out and unloved, are cheered up when Santa and Rudolph arrive to pick them up. The special ends with Santa wishing the viewers a merry Christmas as he and Rudolph fly off into the night.
