Blizzeta

Twilit Ice Mass: Blizzeta is the boss of Snowpeak Ruins, the fifth dungeon in Twilight Princess. The boss is actually Yeta, who leads Link to the second shard of the Twilight Mirror which she holds. She becomes possessed by the Mirror Shard and screams at Link that he cannot have it. The windows of the bedroom then shatter, letting the snow and ice to pour in, surrounding and encapsulating Yeta.
