While he was not originally a one of the available bachelors in the Japanese version, he became one later with a free update. Woofio will reside in Lulukoko Village after he has become available to interact with. He will not participate in any Festivals except for Fruit Festival and Winter Thanksgiving Festival. You can have a child with Woofio and you can get all family events with him, but he doesn't have a spouse exclusive event (that is usually required to be seen before you can get the pregnancy scene) and you can't have meals with him either.
