Breaking the Laws of Gravity
You land on a tube that goes inside the planet. The first part is simple, you just have to drop yourself, but take care of the Paragoombas that fly back and forth. Once you have arrived at the bottom, you can get some coins on the left by pressing a switch. Then move on to the right.
The second part is a little more difficult. First, move to the right, avoid the opponents and press the switch that reverses gravity. Then move on to the right, use the platform up and defeat the purple piranha plant, which brings some Star Bits. Turn at the plant to get down where gravity is different. Continue to the right.
In the third part, gravity plays an important role. At the beginning, let yourself slide down, if you collect the big? coin before, there are coins during the slide down. Now jump up onto the platform that is moving. Then, when the upper platform is above the lower one, jump up, gravity works and you get to the lower platform.
Now go on. At the beginning, gravity is down. Now go up using the platform. There's a switch there. Press it around the gravity you rotate. Now you have to go back and progress using the moving platforms in the level.
Now move on so that you come to a place where Chain Chomps roll, they roll only from left to right. Pass them carefully. Now go through under the two Thwomps without being crushed, then you immediately lose a life.
Comet Medal
Between the two Thwomps, you must cleverly use the wall jump to reach the Comet Medal.
Now move on to the right.
In the next part, you need the Fire Flower that often lies around. At the beginning, grab the Fire Flower above and destroy the boxes below to get further. You will find boxes and fire flowers in the complete fourth part, it is easy in itself, but there is one thing to consider: the boxes must not fall on you, otherwise you will lose a life immediately. Follow the path and destroy all the necessary blocks to get ahead.
The fifth part has completely different gravity conditions than in the parts before, this time you will walk along the “wall”. With this camera angle, it is easy that you collide with an opponent or fall down. So pay attention in this part, because there are many opponents and it is not easy. When you do, the last part comes.
The last part is about being fast. Six Thwomps, three from top to bottom and three vice versa are waiting to crush them. Once the first one has ramped up, race quickly and run quickly under all the Thwomps. Once you’ve done that, all you have to do is collect the Power Star.
To reach the star, you must jump as far as possible from the starting point to the right, but still in the red gravity area. With this trick, you stay inside and slide down the walls. You should actually reach the star, if not, help with a spin.
The Great Crate Incinerator
This hidden-star route branches from the first mission.
You need to use the tube that will be accessible in the second part when you rotate gravity for the first time. Through these you come to a red room. Using the Fire Flower you can destroy the boxes. In the corners there is a coin, except in the bottom left, there is a 1-Up Mushroom. Destroy the middle box from the top right and use the tube below.
You come to another planet where a robot and some boxes can be found. The Gearmo gives you the task of destroying all the boxes in 20 seconds. That is not so easy. It is best to try to destroy the boxes in rows (a fireball can destroy several boxes), as they are quite normal boxes. For this you need precision so that you really meet all the boxes in the row. If you destroyed them all, the Gearmo thanks you by giving you a Power Star.
Comet Medal
At the two Thwomps, use the walls between them to wall-jump up to the medal. Wait for a clear opening rather than jumping under a descending Thwomp.
Green Stars — unlock requirement
Collect all 120 regular stars and defeat Bowser again to unlock the Green Star hunt. Choose the corresponding Green Star mission from this galaxy’s mission screen. Follow the detours below rather than collecting the normal mission’s ending star.
Green Star 1
Replay Breaking the Laws of Gravity. After the third checkpoint, stop before the green puzzle-block section. Jump and spin towards the star between the two areas; a wall jump can supply extra height.
Green Star 2
Near the normal mission’s ending, ride the last Thwomp upwards. Jump onto the ledge with the Toad and Star Bit crystal, then backflip towards the wall, wall-jump and spin into the high star.
Check each numbered Green Star on the mission screen after collecting it. The routes finish immediately when the star is touched, including stars suspended over a gap.
