Rudolph after been encouraged by another buck named Fireball to go and talk to her, he and Clarice agree to walk home together and then Clarice tells Rudolph that she thinks he's cute. This causes Rudolph to leap in the air with joy, which impresses, Rudolph's parents Donner and Mrs. Donner, Santa Claus and the coach Comet. However, Rudolph's fake nose falls off, revealing his red nose which causes him to be laughed at by the other young bucks and is banned from the rest of The Reindeer Games by Comet.
