The Base itself is built into the face of a rock shelf on the southeastern section of Bonechip Island.
The Hero first ventures here after thwarting the BB Brigade at the Seabed Cavern. Here the player fights Lola and Lester before finally battling Don Boneyard, the head honcho of the BareBones Brigade.
In the postgame, the BareBones Brigade Base is the location of The Champions Tournament.
