Bowser's Dark Matter Planet - Darkness on the Horizon

Welcome to the Galaxy!
Mario
We land in the galaxy, which has a lot of dark matter. Falling into dark matter is like falling into the quicksand: instant death. We take the green and yellow platforms that rotate to an area with Dry Bones. We enter a 2D area with gravity arrows. There are moving platforms that will move into areas where the gravity arrows change directions, so look ahead and stay on parts of the platform that you won't fall from when the arrows change. At the end of the path, we find a Goomba and a flagpole.
At the top of the flagpole is a Luma and moving squares in the floor. The Luma informs us, "The dark matter is eating holes in space! Watch out for those holes, or you'll fall into that dark matter!" We have to avoid falling into the "clear holes" in the floor. Next are three pink platforms that pass through the holes. We must take them to the other side, avoiding the holes in space. On the lowest of the three is a 1-up. After that are circling platforms that pass through holes as well. On the other side is a 1-up in crystal. We walk along the path, going upside down. There is another 2D area with gravity arrows. We take some platforms up and take some checkered platforms. We then find some Lumas in crystal. Breaking the crystal will make stairs to the next area appear. We also get a Life Shroom from the crystal. We go to the top of the stairs.
Bowser drops down, saying, "WHAA--?! IT'S YOU! That's it, Mario! I'm gonna stomp you into space bits!" He roars and we float to a new planet. He jumps and lands, creating shockwaves. He now has our spin move, with purple energy. We, once again, have to make him land on the blue circles so he'll run around and we can spin him. We must do this three times. After the third hit, he says, "BWAHAHAHA! Not bad! I guess I chose the right guy to be my archenemy. At least you always put up a fight. But it's too bad for you, because my master plan is almost complete. Tough luck, Mario!" He spins and poofs away. The Grand Star appears from a blue circle.

Interlude
The Grand Star flies into the Beacon, turning it a cobalt blue. The top area of the Observatory lights up. The map shows us that five galaxies in the Engine Room and one away from the Observatory have been discovered. Rosalina says, "We have ascertained the location of your special one. Please take a look at the circle by your feet." The Star in the center of the ring turns into a number. For us, it's "01". "That number represents the Power Stars you need to reach the center of the universe. That number will decrease with each Power Star you recover. And when it reaches zero, the Comet Observatory will regain full power and fly as a starship again. And then we will be able to reach the center of the universe." The Red Star music plays. Rosalina says, (because we have enough Stars- 60+), "The Comet Observatory has full power! Now it will fly through the cosmos again." The number on the floor drops to zero. Rosalina continues, "It's time. Do you want to go to the location of your special one at the center of the universe? Wait / Go" I decide to wait because I want to get as many Stars as possible before I go there." Rosalina says, "Please speak to me again when you are ready." Just talk to Rosalina when you're ready to go.

Luigi
We land in the galaxy and take the yellow and green platforms to the area with the gravity arrows. We climb up the flagpoles and pass the dark matter holes. We reach the second area with gravity arrows, but fall into the dark matter.
Take 2- We fell of the planet.
Take 3- We get a 1-up and free the Lumas for the stairs. We get a Life Shroom and reach Bowser. He gives the same speech, but calls Luigi by his name. We get in the three hits by tricking him into landing on the blue circles and spinning him.
GRAND STAR GET #4!
Star Get #62, Galaxy Complete!, 14 Coins, 3456 Star Bits, 39 Lives

Interlude
The Grand Star turns the beacon a cobalt blue. We open the Engine Room and the Center of the Universe. Rosalina gives us the same speech and asks us if we want to go to the Center of the Universe. We're going to wait and get more Stars.
