Mutoh is an old and short-tempered boss of a group of carpenters who are responsible for building structures around Hyrule and other lands. However his employees are always lazy or either lost to which he has to yell at them. He first appears in Ocarina of Time where during the present he's busy constructing a building in Kakariko Village.

Seven years later in the future, they're found in Gerudo Valley where all the carpenters except for Mutoh are captured by the Gerudo after a failed attempt in joining them. Link later has to help free them so they can escape. In this game only, he has two children, Anju and Grog.
