In "The Legend of Zelda: Phantom Hourglass," the key you seek in the seabed is located in the Temple of the Ocean King. To find it, you need to navigate through the temple's various floors, solve puzzles, and defeat enemies. The key is typically found in a chest after completing certain challenges within the temple. Make sure to explore thoroughly and utilize your map for clues!

Find it in the ocean! If you went to the temple of the ocean king for the third time, then go to the courage symbol on the map, and haul the treasure up! To get the treasure retriever, talk to the guy who gave you the canon.
