Battle Belt Galaxy

Battle Belt Galaxy is a galaxy in the game Super Mario Galaxy 2, located in World 6. The galaxy is unique in that in order for Mario or Luigi to advance, he will need to defeat every enemy on a planet. The enemies start easily with foes such as Goombas, Urchins, Li'l Cinders, and Crabbers. However, the planets will get progressively more complex with enemies like Jack O'Goombas, Boos, Li'l Brrs, and Undergrunts. On the final planet, Mario will need to defeat four Homing Chomps using the rubbery bulbs. A fiery version of Gobblegut is fought as a hidden boss when the player feeds a Hungry Luma on the Li'l Brr Planet 20 coins. The music of this galaxy is the same as the music of the Space Storm Galaxy's first mission.

Planets
NOTE: Unless otherwise noted, all names are unofficial.

Starting Planet
The planet is a small brown planetoid that bears mathematical similarity to a truncated icosahedron. It could be referencing a Soccer Ball. The only enemy here is a Mini Goomba. Defeating the Goomba will make the Sling Star appear.

Li'l Cinder Planet
This is a small, brown planet covered in pools of lava. Only three Li'l Cinders reside here and the Comet Medal is found here, on top of one of the lava pools. There is also a Bill Board here, who informs Mario that the only way to finish the level is to defeat every enemy.

Urchin Planet
This is a small, brown planet with three crates and three red Urchins. A Fire Flower is found here to help the player defeat the Urchins. The player can stand on a wooden crate and backflip to land on the Crabber Planet.

Crabber Planet
This planet is covered in sand and is generally small. The only enemies here are Crabbers, two red and one blue.

Jack O'Goomba Planet
The planet is shaped like a Jack O'Goomba's head. There is a Warp Pipe being protected by a shield. There are three Jack O'Goombas on the outside of the planet. After they are defeated, a key will appear on the planet's nose which will deactivate the shield and the player will need to enter the newly opened Warp Pipe that leads inside the planet. Inside, the player will need to defeat six Boos using the light from a Green Shell.

Li'l Brr Planet
This is a small planet made completely of ice and shaped like a Li'l Brr. The only enemies here are Li'l Brrs. A Hungry Luma can be found here and will ask for 20 coins. If the player feeds it the 20 coins, it will transform into the Gobblegut Planet. The shape of the planet is geometrically similar to an. This planet is also one of three planets that appear on the cover of Super Mario Galaxy 2.

Gobblegut Planet
This is a small brown planet that the player travels to during the Snacktime for Gobblegut mission. On this planet, the player fights a fiery version of Gobblegut.

Undergrunt Planet
The planet is small and grassy. It is the dot of the Question Mark Planet of the Gusty Garden Galaxy from Super Mario Galaxy but with a few differences. There is a shield guarding a Warp Pipe. Two Undergrunts dig around the dirt roads on the planet. After the player defeats the Undergrunts, a key appears that deactivates the shield and the player should travel down the Warp Pipe. Inside, there are three Swaphoppers. Inside this area, the player needs to wait for the gravity field to change with the beat of the music. After all three Swaphoppers are defeated, the way to the final planet is revealed.

Homing Chomp Planet
This is the final and biggest planet of the galaxy. The Power Star is being protected by a shield that needs a key to open it. On this planet, there are four Homing Chomps. They will home-in on the player and try to ram into them. If the Chomps ram into each other, they will simply bounce off. The only way to defeat the Homing Chomps is to use the plethora of rubbery bulbs located on the planet. After all four are defeated, a key should appear and unlock the shield, allowing the player to collect the Power Star.
