Airway (Mario & Luigi: Bowser's Inside Story)

Airway is the final area Mario and Luigi explore in Mario & Luigi: Bowser's Inside Story. It is apparently located Bowser's lungs. The airway has all of Bowser's DNA and is the place where the Dark Star is fought. In order to progress through the Airway, Bowser must inhale a stream of ice from Blizzard Midbus's snout, and alternate in-between to get to the end of the area.

Trivia

 * If the player saves while the Dark Star is in the Airway, the last sentence in the save message says that the Airway is called the Air Space, the Japanese name for the Airway.
 * The airway is regarded as the best place to train the Mario Bros., as an Emoglobin states that the Mario Bros. can train quickly in the Airway.
