Yeta

"NOT TAKE MIRROR!!"

- Yeta under the influence of a Mirror Shard

Yeta is the wife of Yeto and lives with him in the Snowpeak Ruins in Twilight Princess.

Biography
Yeta is apparently sick ever since they found a piece of the Mirror Shard. After Link obtains the Ordon Pumpkin and the Ordon Goat Cheese for Yeto, he will put it into his soup and serve it to Yeta, who will become well enough to lead Link to the top room in the Ruins, where the Mirror Shard is located. However, after she gazes into the mirror, she becomes corrupted and is revealed to be the dungeon's boss, Blizzeta.

Her original form appears to have a human-like face, and she looks like she is wrapped in an extremely large blanket, though it is never confirmed as to whether or not it's clothing, or fur.

She is an avid fan of snowboarding and will give Link a Piece of Heart if he can beat her in a Snowboard Race down Snowpeak Mountain. She is faster than her husband and prefers to take a shorter, albeit, more dangerous route down the mountain.

Super Smash Bros. Brawl
Yeta appears as a trophy in Super Smash Bros. Brawl.

Theory
Some fans theorize that Yeto and Yeta found the shard of the Mirror of Twilight in Zora's Domain, and Yeta's sickness is a result of being corrupted by the shard's evil magic and becoming Blizzeta. This would also account for Zora's Domain having been frozen over, as it would have been Blizzeta's doing.
