Matter Splatter Galaxy

Matter Splatter Galaxy is a galaxy from Super Mario Galaxy. Matter Splatter is a primary stage element in this galaxy, and it consists of droplets of matter that act as disappearing and reappearing platforms Mario can land on; the Darkness Room Planet in the Ghostly Galaxy uses the same concept as this level, although it is much shorter. Magikoopas are the only enemies in this level which appear frequently. Space Fantasy is the music that plays throughout the entire level.

Dark Hopper Planet A
Dark Hopper Planet A is the first 3-D area in the level. It contains what seems to be a large room, however, players can stand only on the parts of the room they can see. There are tiny droplets of matter, and players must jump in the puddles of matter they make. Players must also avoid Magikoopas to get to the pipe.

Dark Hopper Planet B
Although Dark Hopper Planet B seems 2-D, players can fall off the edge towards the camera. It is a dark area with more matter droplets that players must follow to get to the pipe. There are also more Magikoopas trying to stop players.

Dark Hopper Planet C
Dark Hopper Planet C is a 2-D area in the level. In this part, players must grab a Spring Mushroom and climb a wall to reach a pipe at the top. There is an ascending spotlight of matter that players must follow or they fall off the planet.

Dark Hopper Planet D
Dark Hopper Planet D is the second 3-D area in the level. In this part of the level, a small network of walkways lead to the power star, but are hidden until shone upon by the spotlight of matter, which players must again follow. Once players reach the Power Star at the end, however, there is a Magikoopa that tries to prevent them from reaching the Power Star.

Mission
This galaxy contains only the following mission.
