The Bluff Barn is a large barn located in the Farm Heights of Cliff Farm in Banjo-Kazooie: Grunty's Revenge. There isn't much inside the barn itself besides a Gruntling, but there are two important rooms located within the barn. One room is The Rafters, which can only be accessed through a small hole in the wall as Mouse Banjo, and the other room is Klungo's Lab, a secret room that can only be accessed by activating a nearby Witchy Warp pad. Outside on top of one of the barn's silos, Banjo can find an Empty Honeycomb Piece.
