Fire Bar Cliffs

Fire Bar Cliffs, or Superstar Road-6, is the sixth course of Superstar Road in New Super Mario Bros. U. It is unlocked when the player collects every Star Coin in Rock-Candy Mines.

Layout
The course is based of courses from Rock-Candy Mines, most notable Waddlewing's Nest. The main gimmick and obstacle of this course are large Fire Bars that spin at moderate speeds. Climbing and Donut Blocks are used prominently in this course.

Star Coins

 * Star Coin 1: In a crevice guarded by a Fire Bar.
 * Star Coin 2: Before a series of Fire Bars is a wall with a Warp Pipe hidden within. The pipe leads to a underground area where the second Star Coin resides.
 * Star Coin 3: In the last section of the course before the exit is a wall to the left with a Warp Pipe. The pipe leads to another area where the third Star Coin is held.

Enemies

 * Fire Bars
 * Koopa Troopas
 * Buzzy Beetles

Trivia

 * Despite being based of a Rock-Candy Mines course, which normally plays the overworld theme, the volcano theme from New Super Mario Bros. Wii plays instead.
