Boggspine Knuckles

Boggspine Knuckles drop from Hungarfen in the Underbog.

In Hearthstone
The Boggspine Knuckles appear as HS Boggspine Knuckles (an epic weapon) for the shaman class in the Ashes of Outland expansion for Hearthstone. The flavor text reads: "I would NOT want to put my hand in there. It's... SQUISHY."
