- "You say you've never heard of my little Richard? He was such a famous puppy! You seriously haven't heard of him?"
- — Mamamu Yan
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 home in the 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, and as most are indiscernible from each other, and any dog Link approaches will follow him around, only allowing one to do this at a time, finding Richard is no easy task. Richard can be found behind a stall near the entrance to the market. If Link can manage to find him and bring him back to Mamamu Yan, however, she will give him 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, and then goes on to talk about how famous of a dog he used to be. Though it is never directly stated, this dialogue seems to imply that Richard had passed away sometime during the seven years Link was trapped in the Sacred Realm.
