Space Junk Galaxy



The Space Junk Galaxy is a galaxy in the game Super Mario Galaxy. This Galaxy has a futuristic/space theme. A lot of the objects are silver or blue, and there is a spaceship in it.

The Pull Star is used much more than in the other known galaxies. Also Toads are on a big platform covered in crystals; if Mario frees the Toads trapped in the crystals a Mushroom-shaped spaceship will appear to take Mario to the next location. There is also a wooden planet shaped like Yoshi's head.

The last unique feature of this galaxy is that it has a path that builds itself when Mario approaches it, but crumbles after he leaves.

Mario fights two bosses in this galaxy: Tarantox and Kamella.

Crystal Planet


The Crystal Planet is a planet that is encountered shortly before the battle with Tarantox.

At first, Mario walks on top of it, which is practically a transparent crystal orb. Once he finds the passageway in, he can go under the crystal layer and explore underneath, where 1-Up Mushrooms and other treats are waiting. There are also a few Space Rabbits underneath the crystal layer, who guide Mario through to the Launch Star.

Rock Planet


The Rock Planet is a planet mostly made of maroon, dark red, brownish rock. It has a sort of arch, as seen in the picture. This planet is an entrance to Tarantox's lair. The pre-boss music begins when Mario lands on this planet, and the spider's Sticky Planet is nearby.

The Rock Planet is the first planet in the game to have a Sling Pod and is the beginning of a long path of them.

Space Ship


The Space Ship is a "planet" that consists mostly of just coins. It is a big, long, red-and-tan space ship floating around in space. It is encountered on the route to Tarantox. At the end of it is a Sling Pod, and that's literally all there is, along with a few Cosmic Scuttle Bugs. It's also thought the ship is Olimar's ship, referring to the Pikmin series. But this has not been confirmed.

Sticky Planet


The Sticky Planet is exceptionally large and looks like a giant version of the top of a Sling Pod. In fact, Mario uses a Sling Pod to get to the planet, breaking its shell open and revealing a giant sticky spider web, where he fights Tarantox, who is frozen inside the Sticky Planet.

Yoshi Planet


The Yoshi Planet is a planet in the shape of a large, wooden Yoshi head that shoots red steam out of its nostrils. This appears to be the second reference to the Yoshi clan in Super Mario Galaxy, the first being the Yoshi Egg Planet that was shown earlier.
