Buoy Base Galaxy

The Buoy Base Galaxy is a galaxy that appears in Super Mario Galaxy. The galaxy contains a large fortress floating atop a large, spherical pool of water. Mario has to climb this fortress in order to get the main Power Star in this galaxy.

Buoy Base
The Buoy Base is the main part of the galaxy that is made of a large water area and an area above it which contains many obstacles along with a lower portion. The obstacles include Thwomps and Topmen. The main goal of this portion of the planet is to collect Star Chips to build a Pull Star that leads to the Aquatic Dome Planet. The bottom portion has Bill Blasters and a cage containing a Green Star.

Poké Ball Planet
The Poké Ball Planet is a giant sphere filled with water above the Buoy Base. It has a screw on it that Mario must Star Spin to open the planet and retrieve a power star inside of it and also two pulse-wave generating machines, one of which is actually the screw. It is remarkably small in comparison to the Buoy Base, and is remarkably easier as well. It looks like a giant Poké Ball.

The Floating Fortress
In The Floating Fortress, the objective is to scale the fortress and receive the Power Star, located on a planetoid above the fortress. In order to do this, the player must first enter the pool of water and release the weight from within by directing the attacking Torpedo Teds towards the weight. Then Mario must begin his ascent, surviving the various traps that have been put in place to stop him, collecting the five blue star chips, to eventually lay out a path of Pull Stars towards the next planet. There, Mario has to head to the top of the planet, where it is opened by spinning on a gold screw.Then Mario/Luigi must dives in to retrieve the Power Star.

The Secret of Buoy Base
This time, when Mario dives into the surrounding pool of water, he must seek out a caged green pipe, and open it by luring the Torpedo Teds into it. The pipe takes Mario to the outside of the planet, where Mario must lure Bullet Bills into a cage that contains the Green Power Star. Falling off the platforms underneath the planet results in Mario ending up back in Buoy Base's water pool.

Trivia

 * It is one of the two ? Block galaxies to have only two stars, the other being the Gateway Galaxy.
 * The second star of Space Storm Galaxy in Super Mario Galaxy 2 is partially based on Buoy Base Galaxy, even reusing its background music and utilizing a similar tower, with many of the same obstacles returning including Thwomps and Amps.
 * The large tower in this galaxy is almost identical to the Topman Tower from the Space Storm Galaxy. It features many of the same obstacles and enemies, as well as having an overall similar appearance (excluding of course the wide portion of the Topman Tower towards the bottom).
