The Spirit World is a world inhabited by spirits of the deceased. The world itself is full of floating islands clouded by fog, containing various platforms, buildings, as well as the spirits of some animals. These can only be seen and/or used, however, by being in Spirit Form, which can be temporarily granted to outsiders through the use of a Spirit Vent. Its first and only appearance has been in Tak and the Power of Juju, where Tak is sent to retrieve Lok's Spirit, as well as collect any nearby Yorbels.
