Boss Fight
The boss fight with Bowser is said to take place on a larger airship than the ones in the regular level. Bowser will have a mixed moveset from all 3 main Bowser levels. The player will not be able to fling Bowser to bombs directly, instead having to throw him into gusts of wind leading to the bombs. The player has to do this 3 times to defeat them.
