Red-Hot Run

Red-Hot Run or  is the third level of World Castle in Super Mario 3D World. It is unlocked by completing Fort Fire Bros., and its own completion unlocks Boiling Blue Bully Belt. It is a 100-second level, like Pretty Plaza Panic and Backstreet Bustle, but considerably longer, thus incorporating the use of Dash Panels.
