The entrance to this small habitat is found close to the river bank east of Trinsic in the mountain range which encloses Hidden Valley (121.27’S 27.12’E 1710, 3006). Occupants of this primitive dwelling under the mountain are a tribe of Troglodytes; their leader, Lurg; his pet bear, Grobu and various other pet bears, cats and dogs. The condition of the dwelling also has invited giant rats to join them there.
