DS Airship Fortress

Airship Fortress is the fourth and last course of the Star Cup in Mario Kart DS. The course is placed in a fortress floating that's in disrepair in the gloomy sky and in an airship as well. All the course was inspired by the environment of boss levels seen in Super Mario Bros. 3 and Super Mario World. Other airships can be seen flying away in the sky.

The most notable feature in the course is the Pipe Cannon that shots racers out to the fortress through the air. Furthermore, the track includes harmful obstacles like Bullet Bills, Rocky Wrenches and more. Airship Fortress is the only course in the entire Mario Kart series to feature Bullet Bills being shot right at a player. Missions 6-2 and 7-7 are carried out here.

Layout
The track starts in a straight way, where a barrage of Bullet Bills shot from a Pipe Cannon of the craft will wipe any vehicle out if they collide. Passing this section of the track players will turn and get a boost running over a Dash Panel to enter to the deck of the airship. Outside the ship, racers must dodge the pesky Rocky Wrenches that pop out from their trenches to attack the racer whom goes toward it. Proceeding inside the airship, players take a tight turn and reach the cellar where some crates spread in the room may contain a useful Mushroom or an unpleasant Banana Peel if the Kart breaks the box at great speed. The next room to follow includes burners moving to the sides, that players can spin out of control if they touch the fire. Players go out from the airship launched by the big Pipe Cannon after a dash pannel, similar to DK Mountain, to arrive in the tower of the fortress through the hole the cannon clearly aimed. Turning around through the corkscrew in the tower to go down, players finish the race. The players can also push other racers into a crack at the very end of the course and once they pass the finish line they will be down one lap. This may not work all the time.

Missions
There is a mission where the player has to hit 15 Rocky Wrenches using Stars. The player has 30 seconds to complete it. But once the player runs out, the player has to get another Star in the Item Box. Stars always appear every time the player breaks one.
