Course 3
This course is another underground area, with an industrial theme. The level is devided into two major inside areas and two minor outside areas. The pink pipe route is both a shortcut and a hub for the many chambers of the lower area, the factory interior, which is the central area of the level. Both the beginning and the end of the level takes place outside during the quiet night. This level is full of flipping and rotating platforms, conveyor belts and spikepits. Some sets of brick blocks flip open as the player approaches them while some require a push of a button or defeating a Chain Chomp.

Star Coins

 * Star Coin 1: At the end of the fall, as the player enters the level, they must use a Bob-omb, Gold Flower or Super Leaf to break away the brick wall on the left. The Star Coin is behind that wall.
 * Star Coin 2: In the area with the 2 doors, the player must hit the ?-Switch to make the left one accessible. The player must then defeat the Chain Chomp inside the room to open the top part of the room where the Star Coin lies.
 * Star Coin 3: At the very end of the level, the player has to break away the brick wall with the tanooki tail or golden fireballs. The Star Coin is behind that wall, hovering above a set of spikes.

Enemies

 * Bob-ombs
 * Chain Chomps
