The Goblins are small creatures that act as street vandals, leaving a wake of destruction wherever they go. They move in large groups and if one of them is killed, the others will not rest until they take revenge of the murderer and whoever gets in their way. They usually work for the Gumm-Gumms and are particularly attracted to the terror pheromone. A lot of Goblins get smashed into green goo. They are the ones that steal humans and replace them with Changelings.
The Goblins are usually blue or green. However, the Blood Goblins that inhabit the Darklands are white.These Goblins are much more ferocious, voracious and bloodthirsty than the other Goblins, chasing any scent until they find it.
