Pendulum Castle

Pendulum Castle, or Superstar Road-8, is the eighth course of Superstar Road in New Super Mario Bros. U. It is unlocked when the player collects every Star Coin in Peach's Castle. It is usually considered the game's hardest level.

Layout
The course is based off of the castle levels throughout the game, specifically The Final Battle. The main obstacles throughout the entire course are the Spinners. Donut Lifts also make up a majority of the platforms in the level.

Star Coins

 * Star Coin 1: The first Star Coin is located below a row of Donut Lifts and a pair of Spinners.
 * Star Coin 2: Directly after the first Star Coin, the player should wall jump into a hidden area with a Warp Pipe. In there, the star coin is blocked off by three giant Spinners. The Star is required in order to safely obtain the second star coin.
 * Star Coin 3: At the end of the stage, the player needs to hit an Orange ? Switch to make red blocks appear. These red blocks will allow the player to cross the bottomless pit and reach the final Star Coin.

Enemies

 * Spinners
 * Bony Beetles

Trivia

 * This is one of the two castle levels with no boss, the other being Red-Hot Elevator Ride.
