Lakebed Temple

The Lakebed Cavern is the third dungeon of The Legend of Zelda: Twilight Princess, located at the bottom of Lake Hylia and accessed through the use of water bombs and the iron boots. The item is the clawshot, the miniboss is a Giant Frog, and the boss is Morpheel. It may be the Water Temple from Ocarina of Time.

Role within the story
The Lakebed Cavern was once a place of worship for the Zora race, but one day, monsters filled the cavern and it was forced to be abandoned (which may imply the cavern is the Water Temple, hence the name change from "temple" to "cavern".) It is the location of the third Fused Shadow.

After delivering light back to Lanayru, Link and Midna used the Zora Armor to venture down beneath Lake Hylia and blow the entrance open with a water bomb.

During the battle with Morpheel], Link pierces the eel's eye, blinding it, and the eel rammed into the side of the chamber, causing a huge hole in the wall to drain the chamber of water. Link and Midna got the last Fused Shadow. Upon going back to the shrine of Lanayru, [[Zant appears and causes Twilight to overun the area again, turning Link permanantly into a wolf with a Shadow Crystal, and nearly killing Midna by exposing her to the light. The two were forced to see Princess Zelda to help them.
