Bowser Jr.'s Fearsome Fleet

"Don't you know when to quit?! I'm gonna enjoy taking you out from the cozy confines of my robot cockpit!"

- Bowser Jr.

Bowser Jr.'s Fearsome Fleet is the last galaxy of World 3 in Super Mario Galaxy 2. Mario fights Megahammer here, a new boss in the game operated by Bowser Jr. in a stage. Hammer Bros. can be found in the pre-boss area. Yoshi is also found in this galaxy; he is essential to the defeat of Megahammer.

There are a few Fizzlits in this metallic planet, and two Bullet Bill blasters in the walls. At the end of the planet is a crystal Mario must break by making Yoshi eat Bullet Bills, and a big platform that takes Mario through some enemies that shoot more Bullet Bills at him.

There are two Fizzlits on this planet and a Lever Switch that activates moving platforms which lead to the next planet.

There is a Hammer Bro. in this planet, along with several Bullet Bill Blasters. After getting on a moving platform, Mario and Yoshi will have to avoid obstacles such as Airships and Bullet Bills. The Comet Medal can be found on the second Airship.

This planet has a Luma Shop, a checkpoint flag, and the Launch Star leading to the Megahammer Planet.

This is the planet where Mario battles Megahammer. It is shaped like a ring with a few Sling Stars and some black and yellow segments that fall off after Megahammer smashes its hammers against the planet or shoots a Banzai Bill at it. There are also some Star Bits around the top of the Megahammer.

Bowser Jr.'s Mighty Megahammer
Mario will land on the First Platform Planet. He must find Yoshi and make him eat a Bullet Bill to destroy the crystal on the planet. This will unlock a new area on the planet. There are more Fizzlits and a lever. Yoshi must turn the lever to activate a moving platform in order to reach the next planet. In the way are several Undergrunt Gunners shooting Bullet Bills at the duo and many Mines. When Mario and Yoshi reach the second planet two more Fizzlits and another lever and platform await. When the platform is activated, an Undergrunt Gunner, more Mines and another crystal ball with Bullet Bill Blasters block Mario. Mario must break the ball to reach the Third Platform Planet. The lever for this planet is encased in a crystal dome that Yoshi must shoot a Bullet Bill at destroy. Then, when Mario activates the platform, two airships- one with a Hammer Bro.- will appear along with one more crystal ball with Bullet Bill Blasters. When the ball is shattered, the Luma Shop Planet will be unlocked. When the Launch Star is used, the two will fly to the Megahammer Planet, where Bowser Jr. will appear and attach his Robot Cockpit to the body of Megahammer. In the ensuing battle, Yoshi must swallow Bullet Bills to destroy the three blue domes on Megahammer. This will cause Bowser Jr. to expose the windshield of his Robot Cockpit. Mario must hit the cockpit twice with Bullet Bills to bring the mechanical behemoth down. Mario and Yoshi must use a Sling Star to get the third Grand Star so they can enter World 4.

Megahammer's Daredevil Bash
The player will land on the Megahammer Planet. Then he or she will have to fight Megahammer with only one life. The player will have to use Yoshi to defeat the hammering monster once again.

Green Star 1
The first Green Star is located just behind the rightmost Bullet Bill Blaster while riding the platform on the Second Platform Planet. The player must use Yoshi to grab the bullet and destroy the Bullet Bill Blaster to be able to safely grab the star.

Trivia

 * This is the only Galaxy where Yoshi can be in the Grand Star victory pose.
 * In the Italian versions of Super Mario Galaxy and Super Mario Galaxy 2, Bowser Jr.'s Airship Armada and this galaxy share the same name.
 * It is interesting to note that, in this galaxy's Daredevil Comet mission, Megahammer's Daredevil Bash, Bowser Jr. begins the battle by asking Mario if he wants a Grand Star, despite the fact that this mission yields a regular Power Star, as the Grand Star can only be obtained from the first mission.
 * The battle with Megahammer in this galaxy and the battle with Bowser Jr. in Bowser Jr.'s Airship Armada are similar in that each features the use of a Sling Star during the battle. Incidentally, these two battles are the only situations between the two games in which a Sling Star may be used in a battle with either Bowser or Bowser Jr.
