"Poison Wattle Gobbler" is an objective in the quest The Hunger Pangs in The Horrible Hunger of the Ravenous Wattle Gobbler DLC
The Wattle Gobbler will appear out of the Horn of Plenty that it seems to live in. It will immediately dig into the food that has been prepared for it. Torgue will announce the switch of food to the audience as you are released from the force field. Just watch and enjoy. It's about to become an activate patience game.
