Oliver is a Harvest Sprite in Harvest Moon: Skytree Village.
Oliver is the Harvest Sprite of Life. He lives at the Harvest Goddess Spring once awakened after the seventh Skytree is revived. Talk to him to cure sick animals or prolong the life of your animals.
There is no gift-giving in Skytree Village. The only way to build chemistry is to talk to the villagers every day. Unlike previous games, chemistry will not decrease if you do not talk to someone for awhile.
Oliver can be found at the Harvest Goddess spring from 8am-8pm.
