Boss Blitz Galaxy

The Boss Blitz Galaxy is one of the many galaxies found in Super Mario Galaxy 2. It is located in World S and can be unlocked after obtaining 100 Power Stars.

This galaxy pits the player against five bosses from the first game. The player faces off against Dino Piranha, King Kaliente, Major Burrows, Bouldergeist and Fiery Dino Piranha, in that specific order. It contains six planets surrounding a white dwarf star. With the exception of the background music, all five bosses have their original battle themes from Super Mario Galaxy.

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

Dino Piranha's planet
This planet is where the player must face Dino Piranha. It is almost an exact replica of the planet from Super Mario Galaxy, except that now there are no flowers that give coins when shot with Star Bits. All of the other planets in the Boss Blitz can be seen in the distance.

King Kaliente's planet
This planet is where Mario must face King Kaliente. The planet has the same appearance as it did in Super Mario Galaxy, with the addition of both the Comet Medal and a Life Mushroom hidden under the battlefield.

Major Burrows' planet
This planet is where Mario must face Major Burrows. The planetoid itself is an exact replica of the planet found in the Gusty Garden Galaxy in Super Mario Galaxy, except that Major Burrows is not seen chasing a Star Bunny this time around, and it takes place at night rather than day. While the Ghostly Galaxy is encountered before Gusty Garden Galaxy in the original game, in this galaxy, Bouldergeist is instead fought after Major Burrows.

Bouldergeist's planet
This planet is where the player must face Bouldergeist. Little has changed from the original in Super Mario Galaxy, with a checkpoint flag placed near Lumalee. The player will be launched to a small meteorite after the ghoul's defeat.

Meteor planet
This planet is a small gray meteorite with a Launch Star that will take the player to the final planet.

Fiery Dino Piranha's planet
This last planet is where the player must finally face Fiery Dino Piranha. Like most of the other planets in this galaxy, Fiery Dino Piranha's planet is unchanged. Just like on Dino Piranha's planet, all of the other planets of the galaxy can be seen in the background.

Green Star 1
The first Green Star is located on the planet where Major Burrows is fought. The Green Star is located high in the tree. All the player has to do is simply wall jump or perform a backwards somersault up to the star. If the player is unable to fully meet the heights, then they may need to spin right near the star.

Green Star 2
The last Green Star is located below the edge of the Bouldergeist planet, into the abyss. The player must simply head over to the backside of the circular arena while avoiding Bouldergeist's attacks. The player needs to carefully fall off the back of the arena in order to land on the Green Star. Another option is to defeat Bouldergeist first before obtaining the Green Star. This will easily ensure the player the star without the hassle of avoiding Bouldergeist's attacks.

Prima Official Game Guide description

 * "This galaxy is a rogue's gallery of bosses from the first Super Mario Galaxy. Dino Piranha, King Kaliente, Major Burrows, and Bouldergeist have all booked return tickets to the cosmos for this challenge. But none of them is as tough as Fiery Dino Piranha. That fired-up Piranha Plant is back and madder than ever!"

Trivia

 * When Starship Mario goes near or beside the icon, it will give off glittering sounds.
