Mamamu Yan

Mamamu Yan (ママム・ヤン, Mamamu・Yan) is a dog-loving woman found in three 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. The racetrack is located within Romani's Ranch outside of town. 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).

She is the Terminan counterpart of the lady who gives you a Piece of Heart after delivering her dog to her in Hyrule Castle Town. This lady is one of the survivors who flee to Kakariko Village after the castle town was destroyed in the future.

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.
