Bowser Jr.'s Lava Reactor

"If I give up any more Grand Stars, my dad's gonna get MAAAAAAD! So this calls for my ultimate weapon!"

- Bowser Jr.

Bowser Jr.'s Lava Reactor is a Bowser Jr. galaxy in Super Mario Galaxy. This is where Mario battles King Kaliente for the second time and receives a Grand Star. The galaxy is an extremely large sun made out of lava with very few rocks.

This planet is small, made of dirt and is half-gone. There are several Goombas and one Bullet Bill launcher. There are also several cages that can be broken by a Bullet Bill that contain items such as coins, a 1-Up Mushroom and a Launch Star.

This star-like entity is large and is made up solely of lava. There are several sinking platforms around its northernmost region in a circle formation, with more sinking platforms in a path-like formation across its southernmost region. This planet is home to King Kaliente and is where Mario fights him for the second time.

King Kaliente's Spicy Return
Upon entering the galaxy, Mario will land on a small planet with a few Goombas, a Bullet Bill Blaster, a caged 1-Up Mushroom and a caged Launch Star. Mario will have to lure a Bullet Bill to the cage to smash it open, gaining access to the Launch Star. The Launch Star will shoot Mario to the Lava Reactor's surface, which is entirely lava, except for a few sinking platforms. There, Mario will encounter two brown Octopuses that he will have to defeat to access another Launch Star. From there, Mario will encounter Bowser Jr., who will make him fight a much stronger, dark version of King Kaliente while on the sinking platforms. Upon defeating King Kaliente for the second time, Mario will receive the sixth Grand Star.

Trivia

 * It is possible that the player can acquire the 60 Power Stars needed to reach the center of the universe without the Grand Star gained from this particular battle.
 * There is a glitch in this galaxy where one can triple jump on to a cage with a 1-Up Mushroom on the Starting Planet and Star Spin at the height of the jump and actually fall on to the Lava Planet. Since Mario or Luigi will fall no where near where the launch star would take him, the player has no choice but to lose a life by bouncing on the lava.
