Underground Waterway

The Underground Waterway is a cave filled with water and an explorable area in both Final Fantasy IV and Final Fantasy IV: The After Years. In Final Fantasy IVs original Super Nintendo version, the location is named Watery Pass, and in the PlayStation version, it is named Water Cavern.
The Underground Waterway is unique in that it is a single area that is divided into two caves. The first cave consists of two areas, distinctly named Underground Waterway SouthFinal Fantasy IV (Nintendo DS) BradyGames Official Strategy Guide, page 69. and Underground Waterway North in the 3D remake. The end of the latter portion leads to an exit to a small valley area on the World Map. To the north is another cave entrance, which leads into the northern part of Underground Waterway (distinctly named Underground Falls on floor B1 and Underground Lake on floor B2 in the 3D remake).
In Final Fantasy IV, the Underground Waterway is the first place to have a Save Point.
==History==
===Final Fantasy IV===
In Final Fantasy IV, the Underground Waterway is the second dungeon, and Cecil and Rydia travel through it during their search for the Sand Pearl. In the first room, they meet Tellah, who is a blocking the wooden bridge, preventing Cecil and Rydia from progressing. Tellah refuses to let them pass because he says that it is too dangerous with all the monsters in the area. However, if the party has talked to Rosa in Kaipo, Tellah realizes that Cecil is wielding the Dark Sword. He asks for their help in finding his daughter, Anna, who ran off to Damcyan to meet with Edward. Tellah agrees to join the party, and the three of them continue in the Underground Waterway.
On floor B2F, the party enters a camp site. Tellah sets up a tent and says that they should get some rest for the the battle ahead. That night, as Rydia is sleeping, Tellah and Cecil sit around a campfire and discuss a few things; they first talk about how Rydia is a Summoner, to which Tellah says that she has great potential. Both Tellah and Cecil then further introduce themselves, and each of them elaborate on their reason for traveling to Damcyan. Tellah provides a brief description of the boss that lies ahead.
In the North Entrance, which comes after floor B3F, the party takes an exit on the right side, leading them back out on the world map, in an enclosed area within the mountains. Here, the party has a second opportunity to use a Tent before entering the second cave entrance to the north, which features a waterfall. The party jumps down a waterfall which leads down to a lake area where they fight the boss, Octomammoth.
