Goblins

Goblins are creatures who dwell in mountains, especially in Moria and the Misty Mountains. They are a separate race from the Orcs.
== The Lord of the Rings ==
In the Peter Jackson movie The Fellowship of the Ring (2001), the Goblins have overrun the dwarven colony in Moria long before the events of the movie. When the Fellowship passes through the abandoned Dwarf city of Dwarrowdelf, Pippin accidentally alerts the Goblins to their presence, causing a fight to break out in Balin's Tomb. In this instance, their main weapon appears to be a Cave Troll, which has to be brought down by the whole Fellowship, but the entire force is wiped out by the end of the battle.
However, the skirmish allows a much larger force of Goblins to close in on the Fellowship, who flee to Bridge of Khazad-dûm. Unfortunately for them, even more Goblins intercept them in one of Dwarrowdelf's great halls, emerging from cracks in the floor and holes in the ceiling to aid their comrades. Trapped in a sea of Goblins, the Fellowship could only prepare for death, but the evil creatures suddenly paused as a menacing roar echoed in the distance. As a distant hall lit with a fiery orange glow, the Goblins inexplicably fled in all directions, leaving the Fellowship to wonder at their fortune — as well as at what was coming next: Durin's Bane.
=== The Hobbit: An Unexpected Journey ===
Goblins appear in the Misty Mountains, where they capture Thorin and Company. However, Bilbo managed to evade capture before he was attacked by one of the Goblins before they plummeted down into Gollum's cave. Despite being held captive, the Goblins lost control of the dwarves when Gandalf rescued them. A small Battle happened in the mountains, resulting in the Goblins chasing Thorin's company out of the mountains.
