Firefall Cliffs

Firefall Cliffs, or Peach's Castle-4, is the secret fourth course of Peach's Castle in New Super Mario Bros. U. It is an autoscrolling course that involves climbing walls and dodging fireballs.

Layout
The course is an autoscrolling level, so it constantly moves without the player's consent. Fireballs fall from certain points, and the player must climb on certain parts to make their way through.
