World 8-Airship (New Super Mario Bros. Wii)

The last Airship level in the game, where Bowser Jr. is fought once again, but this time Bowser Jr. is in his dad's Koopa Clown Car.

Layout
The main enemy in the course is the Mecha-Koopa, but the biggest danger in the level is the plethora of Cannons, and the players will have to dodge a barrage of Cannonballs at one point. After that, there is a Warp Pipe along with three Cannons rotating on a cog. This Warp Pipe can only be used if it is facing upwards, and it must be used to progress through the level. Throughout the level, the player will have to spin screws in order to progress. At the end is the last battle against Bowser Jr., whose defeat provides access to Bowser's Castle, the site of the final showdown against Bowser.

Star Coins

 * Star Coin 1 - To grab this Star Coin, the player should simply bounce off a Cannonball to reach it.
 * Star Coin 2 - Found in a small enclosure after the midpoint, the player should carefully jump in between two Mecha-Koopas to rach it.
 * Star Coin 3 - In order to grab this final Star Coin, the player needs to be in propeller form. After the second to last screw (and the final squishing platforms), te player should spin another screw, jump down, grab the Star Coin, and fly up and out to safety.
