Gold Leaf Galaxy

The Gold Leaf Galaxy is a galaxy in Super Mario Galaxy that can be accessed from the Engine Room. The galaxy is a mirrored version of Honeyhive Galaxy - with the galaxy's file name even being titled "ReverseKingdomGalaxy" - and shares the same music, though it has an autumn environment and some changes, such as the disappearance of a cave behind the waterfall, the watch tower now being an observatory and relocated, and the addition of Cataquacks and unique planets and areas.

This is one of the three bee-themed galaxies in the game, the other two being the Honeyhive Galaxy and Honeyclimb Galaxy.

Reverse Kingdom Planet
Reverse Kingdom Planet is almost identical to the Honeyhive Galaxy's main planet but with a few differences. The planet is also always in fall (or autumn). To the immediate left of the starting area, there is a group of Star Bits that form a large letter "L", most likely referring to Luigi, in the same position (mirror-wise) as the group of Star Bits to the right of the starting area in the Honeyhive Galaxy, which form a large letter "M", most likely referring to Mario. The planet is also filled with small piles of leaves that release a coin or three Star Bits when the player spins them. A ? Coin can be found under the planet that transforms into a Sling Star when collected, which also creates a line of Coins that lead to a Warp Pipe at the top of the waterfall. The only way to reach the ? Coin is as Bee Mario/Luigi. There is also a 1-Up Mushroom that can be found on top of the skinny tree on the structure housing boulders.

In the first mission, there are five Blue Star Chips scattered across the planet that Mario must find. Mario is given hints by the Star Bunnies as to where the Star Chips are. In the second mission, lots of blue Cataquacks that are owned by the Honeybees cover the starting planet. In the third mission there is a huge tower called the observation deck. The tower is taken over by an Undergrunt in a bubble cannon called the Undergrunt Gunner.

Bump Appear Planet
Bump Appear Planet is a big wooden planet with several water pools with grates over them. There is a switch that can move the grates and make wooden pegs pop out of the ground. There are also blocks that resemble flat ? blocks that slide around and seem to be made of ice.

Poihana Relay Planet
Poihana Relay Planet is a small wooden planet with a small pool, two Wigglers, and a Cataquack. Mario must get the Cataquack to stand on its symbol and get it to launch Mario up to go to the next planet.

Poihana Maze Planet
Poihana Maze Planet is a small planet that looks a lot like the Puzzle Cube from the Gusty Garden Galaxy. Mario must lead the Cataquack on the planet through the maze, get it to stand on its designated symbol and then launch Mario up to the next planet.

M Shape Relay Planet
M Shape Relay Planet is a line shaped like an "M". It has three Cataquacks and Mario must get one of the Cataquacks to stand on the end of the planet and get it to launch Mario up to go to the next planet to proceed.

Flower Planet
The Flower Planet is a big round planet with a grass area, a dirt area, a pool area, two tall towers (one that looks like a Jenga tower), and a floating flower garden. The power star is at the end of the flower garden.

Trivia

 * Between Super Mario Galaxy and Super Mario Galaxy 2, Gold Leaf Galaxy is the only bee-themed galaxy not to have "honey" in the name.
