Super Mario Galaxy

Chapter 10

Ghostly Galaxy

As I was still going up, I saw the mansion a few feet from me. I jumped up and landed on this new world as I looked around this new galaxy. The goomba's had pumpkins for heads and in the distance I can see the huge mansion, filled with ghosts and ghouls of all sizes. I knew for certain that my brother Luigi is somewhere in that mansion. I needed to take action, so I ran my way towards the mansion.

After taking care of the pumpkin heads, I reached the spiraling path that lead into the castle, but as I was walking, I saw a Chain Chomp rolling towards me. I saw an area that was just big enough for me to dodge the incoming ball of doom. After it rolled away, I was able to enter the mansion. I saw a Boo nearby, just hiding its eyes. I already know about these guys. As long as I'm looking at it, it is basically harmless. Anyways, I hit a switch that turned on a light and the Boo was gone. I saw another Boo, so I lured it towards the light and it disappeared, leaving a key on the floor. I grabbed it, unlocking the door behind me.

I stepped inside the room and saw star pieces around the room…and upside down. Looks like I need gravity on my side. I went and walked on the side wall and started chasing after the pieces. After I collected three star pieces, I noticed that the last two pieces were near a black hole. Man, for a mansion, this place really gives me the creeps. I carefully walked around the black hole and got the last pieces of the Launch Star, which appeared above the black hole. I jumped in and launched myself out the window. I managed to stop myself by using the Pull Star. I pulled myself up and was standing near the window of were my brother was being held. I looked to my right and saw a Pull Star so I used it to get around the mansion. I almost fell to my doom if it wasn't for the Pull Star. Once I was back inside, I looked around the room.

I saw a ? Coin, so I picked it up, revealing a ghostly white mushroom. I picked it up and I felt lighter for some reason. I realized that I became a Boo. I decided to put my new power-up to the test as I went through a fenced wall. I decided to turn back into myself as I jumped over the bookcase to find my brother. He looked at me and we just an up o each other and we hugged.

"MARIO! It's so good to see you again. You won't believe all the stuff I had to endure. But, I managed to find a Power Star when I was trapped here." Luigi then gave me the Power Star. I saw a Launch Star right next to me, but before I left, Luigi stopped me. "Don't take that Launch Star, Mario. It will lead you to the Bouldergiest." I just smiled, grabbed Luigi's arm, and launched myself and Luigi near the platform of the so called "ghost". I got to the center of the platform when I heard a rumbling noise and then grunting. I saw Luigi giving me the "Don't look behind you" look on his face, but I turned around. There stood a giant Bouldergiest, just staring at me. I did a quick side flip to dodge the incoming boulders.

As I was running from the incoming rocks, I saw a few black Boos appearing in front of me. "Mario, those are Bomb-Boos. Be careful!" Luigi yelled at me. I decided to pick up one of the Boos, swinging it around, and then I hit the Bouldergiest. It cracked, but was still standing, so I did the same thing again until I saw the heart of the east. I did one mighty Boo swing and hit the heart. But then it came back and with hands this time. He cornered me and was about to swing its giant hand but it's hand fell apart by my brother. "Mario, I'll break the hands while you aim for the heart again." Luigi said while he aimed for the beasts other hands. I managed to grab another Boo and I swinged it at the heart of the Bouldergiest again, but this time, it was destroyed for good. A Power Star appeared as I grabbed it and was thanking Luigi for defeating the foe. "Don't mention it brother. Now, let's get out of this place." As we launched out of the Ghostly Galaxy, I looked back and saw the Bouldergiest reforming again, but a bit bigger this time. I wonder if I was going to see it again. At least I saved my brother from the ghosts but I have a feeling that this won't be the last time that I would see that ghost.

Comet Observatory

I walked towards the garage where my brother was talking to the other Toads and he gave me some great news. "Since you are looking for the Power Stars, I decided to help you on your quest to find them. While you are in another galaxy, just find a green letter from me saying that I found a Power Star in another galaxy and then you can go get the Power Star. Well, see you later bro." Luigi hugged me and ran off towards another galaxy as a Luma was coming towards me. "Mario, head back to the Kitchen observatory, we found another enemy base." I just smiled and ran towards the Kitchen and was preparing for battle. I entered the Kitchen, chose the hidden enemy base, and launched towards the next Grand Star. I'm now thinking of what Bowser and hi son has planned for me. I also wonder what my brother is doing right now.

I landed on an airship a n the distance with Bowser Jr. on it. "Welcome to your doom Mario! Prepare for your final battle!" Bowser Jr. yelled out as he loaded his airship from the distance and started firing at me. I did a side flip and the battle was on!
