When Santa's reindeer go missing just before Christmas, Rudolph and Grover go a-searching. After breaking the reindeer from Mr. Bumble's circus, they are captured themselves. At last they escape, and Santa's sleigh leaves on time.; Rudolph and Grover inadvertently cause trouble as Christmas approaches. Baddy Bear causes trouble deliberately. When all of Santa's crew is trapped by an avalanche, Baddy suggests strapping Rudolph to a spinning fan so that his nose can melt the snow.; Rudolph's cranky Uncle Bloogle despises Christmas, insults Santa, and tries to separate Santa from Rudolph. He's attacked by a polar bear while marooned on an ice floe, then rescued by Rudolph, Santa, and an Eskimo boy, after which he has a change of heart.
