Second Course (Coin Challenge Pack C)

Second Course is the second level of the Coin Challenge Pack C in New Super Mario Bros. 2, as well as the twentieth DLC level in the game.

Layout
The level begins with a few Fire Snakes and a Warp Pipe leading to an underground section with Brick Blocks and Hidden Blocks. Another Warp Pipe takes Mario to a section with Koopa Troopas and a Gold Ring. After the Checkpoint Flag, Mario must enter another Warp Pipe to travel through a series of lifts to the next Warp Pipe. Mario must then enter the furthest left Pipe Cannon followed by the furthest right Pipe Cannon to reach the exit Warp Pipe leading to the Goal Pole.

Star Coins

 * Star Coin 1: In the first underground room, Mario must obtain a trampoline from one of the blocks. Before entering the pipe, he must use the trampoline to reveal two invisible blocks up above, attached to either wall. Mario must use these to take the trampoline up to this new area, and then use the trampoline to enter the yellow pipe up above, containing the Star Coin.
 * Star Coin 2: In the room with the Checkpoint Flag, Mario must wall jump up to the top left to find a secret route. The Star Coin is located within a square of blocks. Two of the bottom blocks are multiple Brick Blocks, and must be successfully hit enough times to turn gold in order to remove them and access the coin. If Mario fails to turn the blocks gold, the Star Coin becomes inaccessible.
 * Star Coin 3: Near the end of the same secret route containing the second Star Coin, Mario must navigate down to the bottom of the area with the blocks he can walk in front of. The Star Coin is in plain sight.

Enemies
