Deep Dark Galaxy

Deep Dark Galaxy is a ghost-type galaxy in Super Mario Galaxy, like the Boo's Boneyard Galaxy and the Ghostly Galaxy. However, the main planet in it has a beach with many Toads and crab-like enemies. There are also Magikoopas near it. The thing that makes it "spooky" is that there is an underwater cavern (it's rather dark, giving the Galaxy its name) filled with "ghost ships". There are very few planets aside from the big, main one. This is also the second appearance of Guppy.

The Underground Ghost Ship
Mario begins on an island of some sort with the Toad Brigade already inhabiting it(They are on a "vacation" although they claim they are searching for Power Stars). Take the spinning Toad's advice and jump into the cannon on the center of the island. Make sure to point your target at the Starman which will give you invincibility. Become Fire Mario and then take the launch star back to the island. Important-try to light both urns in one turn to save an extra trip. Once you've opened the gate, travel into the cave to find yourself facing a small lake. Dive deep into the lake and you will find a lever of some signifigance. Do a spin to activate the lever and open the gate, where you will face a giant jelly. Ignore the jelly thing and swim to the surface. There you will find a ghost ship surrounded by Boos. Climb aboard the ghost ship to fight Kamella. Once you've defeated Kamella, the prize is a Power Star.

Helpful Hints:
 * On the island there is a glowing treasure chest in the water which contains and extra life. Use the floating shell to break open the chest.
 * On the island there are also many star bits. The more the merrier!!!!
 * Before boarding the ghost ship, travel to the west wall to find a super shroom, which will give you three more health points.

Ghost Ship Daredevil Run
This is a semi-difficult challenge involving good skill. Mario starts off in the scene where he lands in front of the ghost ship that is surrounded by Boos. The player will have to go on the ghost ship to fight Kamella, the ugly Magikoopa. The trick is to successfully defeat the clever witch with only one health point. Every now and then Kamella throws a green shell at Mario, which he must use to attack her. The best way to defeat Kamella is to take out the Magikoopas and then wait for her to throw a shell at Mario. Once Kamella is defeated, the player gets a Power Star.

Helpful Hint: Before boarding the ghost ship, the player also has the option to dive down under the ship, collect the ? Coin, and recieve an extra life for collecting fifty or more star bits.
