Goblin

"Goblins have green skin, pointed ears and sharp, white teeth. Many Goblins of both sexes are completely hairless. When a Goblin does have hair, it's dark, wiry and grows only on the very top of the head. Their heads are extremely elongated, with high foreheads and pointed chins. The rest of their bodies are quite Human, though their nails are long, sharp and clawlike."

Goblins and Technology

"Don't underestimate the aerodynamic qualities of the common goblin"

In many setting goblins are very tech savvy people, opposing to the more "magically oriented mind" goblin seen in otherwise. In the Warcraft universe, for instance, goblins are described as lovers of money, explosives and technology"

Tolkien's Imaginarium Goblins

Tolkien utilized the word "gobling" and "orc" interchangeably. See Orc#Tolkien's_Orc for reference.
