Third Course (Gold Rush Pack)

Third Course is the third level of the Gold Rush Pack in New Super Mario Bros. 2, as well as the third DLC level in the game.

Layout
The level begins with a ? Block containing a Gold Flower and a long row of Thwomps before the first Warp Door. Mario will then encounter a pair of Thwomps, followed by a Big Thwomp near a Red Ring. This is followed by two Thwomps guarding a ? Block containing a Mega Mushroom, which is where the level's route diverges.

The normal route sees Mario continue up the vertical area, collecting many Hidden Coins before heading to the next Warp Door. Afterwards, Mario will encounter a Red Ring with a Coin Coffer, followed by a P Switch and a path composed entirely of Blue Coins leading directly to the Goal Pole.

If Mario grabs the Mega Mushroom instead, he will be able to smash through the Brick Block enclosure immediately to the right, leading to an area with Big Thwomps. After a short area with a Checkpoint Flag, Mario will encounter a few more Thwomps before reaching a POW Block which he must Ground Pound to continue on. After one more POW Block, Mario must continue through another Warp Door to reach some columns along with a Big Dry Bones just before the Goal Pole.

Star Coins

 * Star Coin 1: When close to the two Thwomps after the first Big Thwomp, Mario must obtain the Mega Mushroom, head to the right, ground pound the Hard Blocks, and enter the Pipe Cannon when Mario is back to normal size.
 * Star Coin 2: When in the room with the POW Blocks, Mario must go to the left side and keep on going down to find the Star Coin.
 * Star Coin 3: At the bottom of the room with the POW Blocks, when seeing the Thwomps after the second Star Coin, Mario must defeat them with the Gold Flower and jump where the middle Thwomp was, which will reveal some Hidden Blocks. Jumping on top of those and destroying the Brick Blocks above them will make the Star Coin appear.
