The Legend of Zelda: Ocarina of Time Walkthrough: (6) ice cavern
As soon as you enter the Ice Cavern you will notice ice sta- lagmites and stalactites, as well as red ice. This is the same red ice that encases King Zora. Red ice can be melted with Blue Fire, which you will find deeper with- in the cavern. Stalagmites can be removed with a swing of your sword. If you walk underneath stalactites, they will drop to the ground. Protect yourself with your shield, and don’t let the ice get the best of you.
