Red Ice

Red Ice is found in The Legend of Zelda: Ocarina of Time. When Link becomes Adult Link by pulling the Master Sword out of its pedestal in the Temple of Time, It is found in Zora's Domain and the Ice Cavern.

Appearance
The Red Ice closely resembles Nayru's Love, appearing in the form of a diamond and protecting anything within it from damage. But the Red Ice is apparently a red diamond and Nayru's Love is blue. When Adult Link first enters the now frozen Zora's Domain, most of the Zoras are gone and King Zora is now trapped within Red Ice. The only way it can be melted is with Blue Fire, which can be bought for around 300 Rupees (empty bottle required) at some shops. They can also be captured in empty bottles at the Ice Cavern, which has an unlimited supply of Blue Fire in some areas. Many objects in the Ice Cavern are incased within Red Ice.
