Moon is the general practitioner in Tim's Town and can be found at the doctor's office on the second floor above the tailor.
According to gossip overheard at the Pacific Union Camp, Dr. Moon appears to be a serial killer and rapist, however, very little people believe these false claims.
Other than being able to purchase his medicines from the doctor's office, Moon can routinely be found at the blackjack table in the Tim's Town Saloon or just loitering around it and drinking.
