Super Mario 64 Manifestation
Bowser's Castle is oddly missing from Super Mario 64, when it usually appears in most Mario games. However, the Personalization A.I. can make it manifest in place of Princess Peach's Castle or a level, usually in the form of the Eternal Fortress. In the case it manifests in place of Princess Peach's Castle, it is usually a simple reskin, with no new levels, but can also have new geography. It often manifests after a Bad Ending.
