The Fowl Lair

The Fowl Lair is a small dungeon that is a possible outcome of the Ancient Device in Act II of Diablo III.

Just like its name suggests, the dungeon is filled with fowls (chickens) that the player cannot interact with: they just wander around and gobble.

At the end of the dungeon, there is one killable Greasy Pig. Upon death, it drops loot as if opening a Resplendent Chest.

Name of the dungeon is, most likely, a pun towards the "Fo u l Lair".
