Golfimbul
Golfimbul, the goblin king of Mount Gram, is a figure known only through a single, decisive battle that passed into hobbit legend. His death at the Battle of the Green Fields serves as a touchstone for the Took family's reputation for audacity and provides a measure of the latent ferocity that Bilbo Baggins, a descendant of that line, might one day draw upon.
Identity and Legendary Death
Golfimbul was the king of the goblins of Mount Gram. He met his end during the Battle of the Green Fields, a conflict in which the hobbit Bullroarer Took, the great-grand-uncle of Bilbo Baggins, charged the goblin ranks. Bullroarer, who was so large for a hobbit that he could ride a horse, struck Golfimbul's head clean off with a wooden club. The head sailed a hundred yards through the air and went down a rabbit-hole, an event that, according to the narrator, simultaneously won the battle and invented the game of Golf.
Narrative Significance
Golfimbul's story is not a direct event in the main narrative but a piece of family history that Gandalf invokes to reassure the skeptical dwarves about Bilbo's potential. After Bilbo faints at the mention of the dangerous quest, Gandalf describes him as "as fierce as a dragon in a pinch," a claim he immediately qualifies as "poetical exaggeration" by comparing Bilbo to Bullroarer. The tale of Golfimbul's defeat thus serves as the standard of Tookish ferocity against which Bilbo's own courage is measured. It also marks the moment when Bilbo, overhearing the dwarves' doubts, feels the Took side of his nature win out, prompting him to assert himself and declare his willingness to join the adventure. The legend of Golfimbul's death, therefore, functions as a narrative catalyst, linking Bilbo's ancestral heritage to his own incipient bravery and setting the stage for his transformation from a comfort-loving hobbit into a burglar and adventurer.
