"Defeat Wattle Gobbler" is an objective in the quest The Hunger Pangs in The Horrible Hunger of the Ravenous Wattle Gobbler DLC
The Wattle Gobbler is now vulnerable to attack. Turn your fire on it. Deal with the Tributes and other various Chefs or butchers that cross your line of fire. Save the basic foes for when you need to get a second wind. Keep some distance from the Gobbler and it will not be able to do much to you.
