The Zora Mask is one of four Masks used for Transformation.When worn, it transforms Link into a Zora. The Mask contains the spirit of the fallen Zoran hero Mikau, and when Link dons the mask he inhabits the hero's body. With the transformation comes all the special abilities of that species, including a new fighting style, the ability to swiftly swim underwater, two boomerang-like fins as an attack, and an electric barrier shield.

Link acquires the Mask while visiting Great Bay, where he notices a Zora near death floating in the water surrounded by seagulls.Once Link helps the Zora to shore, he tells him that he is Mikau, guitarist for the Zora band The Indigo-Go's.He sings a song explaining that he was trying to help Lulu recover her eggs that were stolen from her by Gerudo Pirates, but was fatally injured in the process. Full of regret, he cannot die in peace, and asks someone to heal his soul. By playing the "Song of Healing," Link can rest Mikau's soul, leaving behind the Zora Mask.
