The Bone Dry Dimension with the Saturn-like planet in the background.
The Sacred Realm, or Bone Dry Dimension, is a realm in the Epic Mario Bros series that was first revealed in the Boot Camp episode. It is a realm that is purple in color, and has a hot pink grid as a floor. Underneath the floor is a raging pinkish fire. The realm seems to be in outer space, near a very large Saturn-like planet. A pink cloud hovers in between. On the other side of the horizon is a pink moon-like planet. It is a rather mysterious dimension, and the purpose of it is unclear. It can be accessed via Warp Portal, but apparently only Dry Koopas have the knowledge to access it.
