Biography
When Link is a child, he meets Mamamu Yan in Hyrule Castle Town. She seems to be infatuated with her pet dog Richard, and she thinks that no other dog could ever match his greatness, referring to them often as "mutts". During nightfall, if Link visits Mamamu Yan's house in a back alley of Hyrule Castle Town, she will tell Link that Richard has run away and asks if he can find him for her. Many dogs roam the streets at night so finding Richard is no easy task, but if Link manages to find him and bring him back to Mamamu Yan, she will give Link a Piece of Heart as thanks.

When Link is an adult Mamamu Yan can be found in Kakariko Village. Here she tells Link that Talon reminds her of Richard. Though it is never directly stated, this dialogue probably means that Richard had passed away during the seven years Link was trapped in the Sacred Realm.
