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 off courses from Rock-Candy Mines, most notably 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: The first Star Coin sits in a crevice guarded by a Fire Bar.
 * Star Coin 2: Before a series of Fire Bars, there 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 off a Rock-Candy Mines course, which normally plays the overworld theme, the volcano theme from New Super Mario Bros. Wii plays instead.
