|On the bottom of the planet.|
|On one of the branches of the tree near the middle.|
Mario starts on the base of the massive planet. It has a giant tree, the namesake of the galaxy, with branches and leaves that Mario can jump on and explore. Some lead to surrounding planets. Mario must use the Bee Mushroom to climb up the tree and make his way counter-clockwise around the tree. Mario can then reach a branch about halfway up, which he can navigate and climb to find a star.
|On a root that springs off to the side.|
Mario must now enter the inside of the tree by discovering a warp pipe on the tree that takes Mario there. Then he drops all the way under the tree to an area where all the roots are exposed. It is hard to navigate, but after searching all the way around and finding a good path, Mario can make it to the star.
|In the middle of the Beeninja hive.|
Although the Honeybees and Beeninjas have made peace over in Ninja Honeycomb Galaxy, they still remain at war over here. Mario must explore the tree and find the hideout, a small hive on the middle of the tree. Mario can enter it and then pick up a star.
|On on of the massive leaves, all the way at its end.|
With the Beeninja conflict now solved, Mario has to complete his last task - climbing all the way up to the top of the tree. He can do this by using platforming skills, as well as many objects placed in his way. The Bee Mushroom is used heavily. At the top, Mario must find Silver Stars on each of the massive leaves of the tree.
Mario must complete the third star under only one wedge of health.
Mario must complete the fourth star in only five minutes.

|Next to a large cluster of Gearpills on the top of the factory.|
Mario begins on the bottom of this massive new clocktower constructed by the Gearmos. With General Gear vanquished for good, they are glad that he won't interfere in their affairs any longer... until a new foe called Owlingwork emerges. This is a large mechanical owl who was a construction project gone wrong. One of the Gearmos takes blame. Mario must track down Owlingwork at the top of the clocktower by the use of his honed platforming skills and travel several planets. The fight has Mario attempt to use the Super Gear to track down Owlingwork and spin in its way.

|Mario must blow up a wall of cement with a Bob-omb.|
The Gearmos tell Mario that he will need to perform some excavation work for them and show him how to use Bob-ombs. Mario must complete a course that makes use of Bob-ombs to blow up cages, as well as piles of trash. Mario can fly all around the surrounding planets and side of the clocktower before finding the star.
