Calvin is one of the Harvest Sprites in Harvest Moon: Skytree Village.
Calvin is the harvest sprite of animals who lives in the Harvest Goddess Springs. He is very passionate and loves to eat.
Ring the bell outside your barn and Calvin will let your animals out to graze. You can only let out one barn at a time.
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.
Calvin can be found at the Harvest Goddess spring from 8am-8pm.
