Bowser Jr.'s Fearsome Fleet is a galaxy featured in Super Mario Galaxy 2.

Bowser Jr.'s Mighty Megahammer
After Mario completes the obstacles, he fights against Megahammer. He needs Yoshi to help him. To defeat him, Yoshi must swallow a Bullet Bill and shoot it in Bowser Jr.'s Megahamer's glassy parts 3 times (don't forget the back part by using the Launch Star). After Mario defeats him, he obtains the Grand Star and is able to go to World 4.
