Koboli

Koboli is the mail sorter of the Rito people in The Wind Waker. He is currently the third generation of postmen, but a small rumor has been going around that there may be ancestor of his from a long time ago that was a postman just like him.

He hires Link to be an assistant sorter and becomes so impressed with Link that he hires another person, Baito.

Theory
Koboli strongly resembles the Postman from Majora's Mask. This makes some theorists think that he might be descended from the Postman in Majora's Mask. Another fact that supports this theory is that on his figurine, it is mentioned that one of his ancestors was a postman.
