Hamhock

Hamhock was a level 25 elite two-headed ogre mini-boss found in the Stormwind Stockade prior to the Cataclysm.

He had no significant loot, nor was he associated with any quests.

Speculation
Some rumors spread throughout various fellow roleplayers that Hamhock was a captured ogre from Duskwood, possibly making him a Splinter Fist Ogre. If this were true he would fall under the possible command of Zzarc'Vul, leader of the clan at Vul'Gol Ogre Mound. Alternatively, he could be a captured member of the Defias Brotherhood.
