Festari is a Forest Minish elder. He can speak both the Language of the Minish and the Hylian language. He guides Link to find the Jabber Nut, which allows him to speak Minish. Festari is also the town's priest and looks after Deepwood Shrine.
In the manga, Festari is very upset about how the Minish are so old-fashioned. He longs to be trendy, and to make his people that way too. After Link returns from Deepwood Shrine with the Earth Element, Festari gains new found confidence and tries to push the Minish towards his goal.
