What do bumbles do in Rudolph The Red Nosed Reindeer?

The Abominable Snow Monster of the North (a.k.a. Bumble) - A large, ferocious ape-like mammal of unspecified species, possibly a yeti. As the main antagonist, he pursues Hermey and Rudolph throughout their adventure. The sight of Rudolph's glowing red nose drives Bumble into a rage. Sam the snowman also explains that the monster hates everything to do with Christmas. Later, the Abominable Snow Monster captures Rudolph and his family at his cave. Yukon and Hermey come to the rescue by knocking the monster unconscious and extracting all his teeth. Near the end of the film he has a change of heart, and he is seen putting the star on top of the Christmas tree and becoming a part of Christmastown .
