Sinking the Airships

Sinking the Airships is the only mission of Bowser Jr.'s Airship Armada in Super Mario Galaxy. The mission's objective is to rescue the Grand Star from Bowser Jr.

Layout
The player starts on an Airship with several Electrogoombas and a cannon. The player has to make use of the various cannons on the Airships to travel between them, using any Pull Stars if necessary. After the third Airship, the player will find a platform that will begin moving once they activate the Lever Switch. The platform will travel between three Airship and stop at a boardwalk at the end, which leads into the final Airship and the fight with Bowser Jr.

Bowser Jr. will remain on his Airship throughout the battle, shooting cannonballs and Bullet Bills at Mario. On the Airship Mario is standing on are several Koopa Troopas Mario can jump on to grab their shell. Throwing the shell at Bowser Jr. will deal damage to him and make him change his tactic. After attacking him twice, Magikoopas will join in the fight. Damaging the Airship three times will cause Bowser Jr. to turn his Airship to face the player, and the Bowser face on the front will start firing three fireballs, in addition to the Bullet Bills and Magikoopas from the previous phases. Damaging the Airship two more times will cause Bowser Jr. to abandon his Airship as it explodes, leaving behind the Grand Star.
