Yammo
Yammo is a character from Breath of the Wild. He works in the stables in Hyrule Field, and Link can get his first horse, Kyle, from him. However, little is known about Yammo because Breath of the Wild is so new.
Use
Yammo apparently works at the stables, or so is said in Game Informer magazine Issue #317. However, he may just happen to have a spare horse with him. It is most likely that he works at some kind of stable or ranch, though. Link is able to obtain his first horse, Kyle, from him. Please note that this may be incorrect information due to Breath of the Wild's recent release. Zelda Dungeon Wiki got this information from Game Informer magazine.
