The Hulking Labgoblin can be found at the Secret Lab[44, 76.8] in Azshara. He pushes the cart for the below quest.
He is likely a reference to the popular TeamFortress 2 Character, "The Heavy" or "Heavy Weapons Guy." In the quest above, he uses the dialog "We must push tiny cart" which is a direct reference to Heavy Weapons Guy.
