After defeating the mini-boss in the Water Temple in "The Legend of Zelda: Twilight Princess," you obtain the Boss Key. This allows you to access the main chamber of the temple where the final boss awaits. You will then need to navigate through the temple's puzzles and enemies to reach that chamber and face the boss.
