Entrance to the Cave

Themes and Navigation
The Mermaid's Cave is a water-themed dungeon. Unlike other dungeons in, Link visits this dungeon twice in both the present and past. In order to complete the dungeon in its entirety, Link must travel back and forth through the present and past forms of the dungeon. The dungeon's layout and color scheme differs between the two time periods. During the present, the entire first floor of the Cave somewhat resembles the shape of a Mermaid, hence the name of the dungeon. During the past, the layout only partly resembles the makings of the future layout. Both versions of the OoA: use NaN Dials as a means of progression.

In the present time of Mermaid's Cave, Link finds the mini-boss, Vire, along with the Boss Key. There he also finds the Mermaid Suit, which is required to explore the submerged section of the dungeon in the past. The boss of the dungeon, Octogon, and the Essence of Time it is guarding, are found in the past. After defeating Octogon, Link will receive a Heart Container and the Lonely Peak, his sixth Essence of Time.
