Grinnah



Grinnah appears only in Peter Jackson's The Hobbit: An Unexpected Journey (2012), in which he is the chief interrogator of the Goblins of Goblin Town, the goblin who ensures that Thorin Oakenshield and Company are brought before the Great Goblin.

History
Grinnah revels in every chance he gets to use his whip on the dwarves. Although cunning and vicious, he is, like all goblins, a coward at heart. Obsequious and fawning, in secret he loathes his master, the fat and capricious, Great Goblin king.

He is first seen leading the captured dwarves to his master, The Goblin King, When he sees Orcrist he panics along with the other goblins and starts attacking Thorin and Co. He attempts to use his whip on several of the Dwarves but is ultimately killed by Kili when the dwarf impales Grinnah through the chest with his sword after Gandalf comes to the dwarves aid.
