Yeta is a character from The Legend of Zelda: Twilight Princess. A female Yeti, she lives in the Snowpeak Ruins with her husband, Yeto. Though Yeta appears to be armless, she actually wears a white, brown and green sleeveless sweater that gives her an “armless” appearance. This also explains the colored argyle pattern across her body, which also has a different texture than the rest of her body.
