Yeta

Yeta is the wife of Yeto, the yeti living in Snowpeak Ruins in the Peak Province in Twilight Princess.

After you obtain the Pumpkin and The Ordona Goat Cheese for her, she leads you to the top room in the Ruins, and after she gazes into the mirror, she becomes corrupted and is revealed as the dungeon's boss.

She is an avid fan of snowboarding and may give you something if you can beat her in a race down Snowpeak Mountain.
