Underground Waterway

The Underground Waterway is a cave location in Final Fantasy IV, and as its name suggests, is filled with water. In the Super Nintendo release, the location is named Watery Pass, and in the PlayStation version, it is named Water Cavern.

The Underground Waterway is divided into two portions. The first portion ends with an exit to a small valley area in the overworld. To the north is another cave entrance, which leads into the northern part of Underground Waterway. This portion starts with a jump down the waterfall. At the end, the party has to fight Octomammoth and continue to Damcyan.
