Mamamu Yan

Mamamu Yan (ママム・ヤン, Mamamu・Yan) is a dog-loving woman found in two games in the The Legend of Zelda series.

Majora's Mask
Mamamu Yan is first seen in Majora's Mask. She owns many dogs, and is found with them at her very own Doggy Racetrack. If you place a bet with her, she will allow you to place that bet on the dog that you believe will win the race (this is made easier by using the Mask of Truth).

Oracle of Ages
Mamamu Yan also plays a part in the Oracle of Ages trading sequence, giving link the Dumbbell in return for the Doggie Mask.
