Spin-Dig Galaxy

Spin-Dig Galaxy is a galaxy in Super Mario Galaxy 2. Most of the planets seen in this galaxy are dirt. Mario can find and pick a drill item to bore the ground of these planets to come down the other side across them or also enter into underground areas. Digga-Leg is the boss that appears in the galaxy.

This is a small planet completely made of dirt. There are three towers of dirt with different heights that Mario can only reach if he finds a Spin Drill around the planet and use it over three marked spots that lead to the towers. The highest tower of the planet has a Launch Star. The planet also contains a 1-Up Mushroom enclosed in a steel cage and a sum of coins on another dirt tower. During the Digga-Leg's Planet mission, there are Diggas and during the Silver Stars Down Deep mission, Cosmic Clones and Piranha Plants are found here. Some of the towers have coins, but one has Spin Lights and a Luma.

This planet looks like a double-sided peanut-shaped platform that has two sides surrounded by a tall steel fence. The player can use again the Spin Drill to access to the other side of the planet. In the upper side there are two high towers of dirt, a small round iron platform and two Twirlips. On the lower side, there are other two towers, in which one is connected to another one on the planet's upper side. Over them, the player can find a Luma that turns into a Launch Star and also a Comet Medal. There are also mini lights that Mario or Luigi can destroy to get three Star Bits

The planet is a ring-shaped platform of steel blocks surrounding a Black Hole. Some big Used Blocks can be found around the ring and are connected to it by yellow platforms that appear and disappear at times. Over these Blocks, the plumber can find a Midway Flag, a Teleporter, and a Launch Star. A 1-Up Mushroom can be found as well over two yellow platforms. Twirlips are found here.

Is accessed by the Teleporter on the Steel Ring Planet. The Bonus Planet contains Twirlips and a Rainbow Star which the player has to use to romp all the enemies on the planet.

This planet is similar to the starting planet, but it is covered in gray dirt and has only a tower, which gives the planet a pear-like shape. The player uses the Spin Drill to bore through the ground and go to the hollow center of the planet to find a plethora of Coins. Inside the planet there is a hole where Mario uses his Drill to go to the top of the tower. A few Goombas can be found on this planet.

This a small circular planet made of dirt where the boss Digga-Leg lies. Stepping on this planet, the player must move to the sides like in a two-dimensional environment during their fight with Digga-Leg. Some black and yellow security bars decorate the planet and two Spin Drills can be found lying here.

In the second mission Mario uses a Beanstalk from the Starting Planet to swing to this planet. At the top is a Warp Pipe and a Teleporter. Inside the first part of the planet there are Spin Drills and Diggas. The player must navigate their way through the dirt by aiming for the corners in the walls to turn and get to another Warp Pipe. In the second area there are three levels of dirt with Amps beneath them. The player must drill at the right time to avoid the Amps and get to the bottom safely. Then the player must take another Warp Pipe at the bottom of the Cylinder Planet where there is a Launch Star encased in an Item Crystal and Star Bits.

This planet that is shaped in the form of a square. The player will need to navigate the planet in a 2D view to find all the five Silver Stars buried. There are many Diggas that keep spawning, and Mario must use the Spin Drill to get inside the core of the planet and collect the five Silver Stars to make the Power Star appear.
