File:GrandStarIcon.gif
Bowser's Dark Matter Plant is a one of Bowser's galaxies in the game Super Mario Galaxy. This galaxy has a two gravity-flipping area, along with patches of Dark Matter which are deadly to touch. Bowser is fought at the end; the fight is much tougher than the previous one. If Mario wins, he receives a Grand Star.
Missions
Darkness on the Horizon
Mario must go through the plant (including two side-scrolling area), avoiding black holes, Dark Matter and the holes it burns into the ground. To avoid the dark matter, Mario must use platforms to travel over the dark matter. However, in the 2D areas Mario must climb to different sides of the platforms because the gravity changes often and will result in Mario falling into the dark matter if he is on the wrong side. Eventually he will reach Bowser who must be defeated the same way he was last time, only this time Bowser's attacks are harder to avoid and additionally Bowser uses his own Dark Spin to attack Mario.
