Supermassive Galaxy

Supermassive Galaxy is the first galaxy of World 4 in the game Super Mario Galaxy 2. Supermassive Galaxy depicts many common Mario enemies and elements at an extraordinary size. Some include Piranha Plants, Lumas, coins and Platforms. The concept can be compared to that of Giant Land from Super Mario Bros. 3 or the 'huge' part of Tiny-Huge Island in Super Mario 64, in which enemies, blocks, and other objects were also giant compared to Mario himself. Mario can traverse across giant Warp Pipes and Blocks. Many enemies here include Big Goombas, Big Paragoombas, Big Koopa Troopas, Big Piranha Plants, Big Wigglers and Big Thwomps. The Big Goombas and Big Paragoombas can be defeated the normal way, by spinning and kicking, and the Big Koopa Troopas can only be defeated by using a Spin Drill. Big Piranha Plants, Big Wigglers, and Super Thwomps cannot be defeated.

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

Starting Planet
The Starting Planet is an area made of Brick Blocks. A giant Luma is found on it. The player will encounter several giant enemies such as Big Goombas, Big Piranha Plants and Big Thwomps. Most of them are invincible. The Comet Medal can be found near one of the Big Goombas. There is also a giant Warp Pipe serving as an elevator and a giant Coin which the player can perform a Wall Jump off of to progress. The Launch Star can be found near two Big Thwomps. There is also is a shortcut by long jumping off the top of the first Big Thwomp. If the player performs a spin, they can break the gravitational pull and land on the Big Koopas Planet.

Big Koopas Planet
This circle-shaped dirt planet is the second planet that players visit in this galaxy. It is populated by three Big Koopa Troopas that continuously walk around it counterclockwise. It looks slightly similar to the planet in the Spin-Dig Galaxy where players fight Digga-Leg. They must use the Spin Drill found on this planet to defeat the three Big Koopa Troopas.

On this planet, if players can jump repeatedly on any Big Koopa Troopa shell eight times in a row and then continue to do so, they can earn extra lives until the total is 99.

Giant Star Chips Planet
Like the first one, this planet is made of giant Brick Blocks. However, the first path is made up of large Star Chips. Another giant Luma is seen here, as well as Big Goombas, Big Piranha Plants and Big Paragoombas. At the end of the planet, there is a series of yellow moving platforms. They will disappear as time progresses, so the player has to jump on them with timed movements. The Launch Star here will take the player to the Blooming Garden planet.

Giant Warp Pipe Planet
This planet is not accessed, but Mario flies through it after being launched by the second Launch Star from the Big Koopa Planet. There are Star Bits found on the walls.

Blooming Garden Planet
When the player lands on this planet, they'll notice it to be just a simple, grassy planet. However, when the player walks around it, flowers will start to appear and bloom. When the flowers completely cover the planet, a vine will sprout, allowing the player to reach the hidden Power Star and complete the mission.

Stone Tube Planet
This planet is shaped like a cylinder made of stones. This planet is inhabited by Big Wigglers, the last two being enraged and running at a faster pace than the others. The player can get past them by using the Long Jump. The Power Star for Huge Trouble With Big Wigglers is located on top of a pole at the end of this planet.

Trivia

 * The Supermassive Galaxy is located in World 4, and World 4 in Super Mario Bros. 3 was named Giant Land, which this galaxy is very similar to.
 * The pole Mario has to slide up to get the first power star is similar to the Goal Pole from various Mario games.
 * In E3 2009, the Blooming Garden Planet was a dirt planet rather than a grass planet, and there were regular Goombas on it.
 * The Stone Tube Planet in this galaxy bears a strong resemblance to The Cyclone Stone in the Beach Bowl Galaxy, as well as the Starting Planet in the Stone Cyclone Galaxy.
 * The music for this galaxy is a remix of Toy Time Galaxy's music from Super Mario Galaxy, which in turn is a remix of the overworld theme from Super Mario Bros.
