Gold Leaf Galaxy

The Gold Leaf Galaxy is a galaxy in Super Mario Galaxy. The galaxy greatly resembles and is basically a mirror of the Honeyhive Galaxy, though it has an autumn environment and some changes such as the disappearance of a cave behind the waterfall. Cataquacks can be found here.

Star Bunnies on the Hunt
In this mission, several Star Bunnies are searching for blue star pieces. After Mario collects them all, they create a Pull Star path which allows the player to reach a planet where the player must catch another Star Bunny. After successfully catching it, Mario will receive a Power Star.

Cataquack To The Skies
The player has to use the Cataquacks to get higher jumps, and reach new planets. Bee Mushrooms will be used at the end as well.

When It Rains, It Pours
The Bees inform Mario that there is an Undergrunt Gunner on the top of the Gold Leaf Observatory. Using mainly Bee Mushrooms, Mario must reach the top of the observatory while avoiding the many rain clouds that have gathered. Once he reaches the top, he must defeat the Undergrunt Gunner for a Power Star.

Cosmic Mario Forest Race
Similar to When it Rains, it Pours, but Mario is racing Cosmic Mario.

Purple Coins in the Woods
Mario must search Gold Leaf Galaxy for all 100 Purple Coins before the time limit finishes. The Bees help remind the player how many Star Bits they should have by the time they talk to them, if it is less then the player has missed some and must backtrack, wasting valuable time.

The Bell on the Big Tree
There is a big tree in a corner of the galaxy's main planet that has a bubble machine at its base. While in the bubble, Mario must knock the bell on the tree with the Star Cursor and float around, collecting all the Musical Notes. Once all the notes are collected, a Power star will appear.

Trivia

 * There is a planet in this galaxy which closely resembles the Puzzle Cube from Gusty Garden Galaxy.
 * In Mario Kart Wii, there is a course called Maple Treeway in the Star Cup that closely resembles the Gold Leaf Galaxy.
 * There are Star Bits that assemble into an L to the left of the starting position, referring most likely to Luigi, in the same position mirror-wise as the Star Bits that assembled into an M, referring to Mario, to the right of the starting position in Honey Hive Galaxy.
