Spin-Dig Galaxy
Template:Newsubject Template:Galaxybox Spin-Dig Galaxy is a galaxy confirmed to appear 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 one of the bosses that appear in the galaxy. Enemies that would include as well are some yellow ground-dweller drill creatures that greatly resemble the Drill Mole from Super Mario Land 2: 6 Golden Coins.
Planets
Starting Planet
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 Drill around the planet and use it over three marked spots that lead to the towers. The highest tower of the planet is found a Launch Star. The planet also contains a 1-Up Mushroom enclosed in a steel cage.
Drill Zone Planet
This planet looks like a platform that has two sides surrounded by a steel fence. Mario can use again the 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 enemies. 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, Mario can find a Launch Star and also a Comet Metal.
Steel Ring Planet
The planet is a ring-shaped platform of steel blocks surrounding a Black Hole. Some big Used Blocks around the ring are connected to it by yellow platforms that appear and disappear at times. Over these Blocks, the plumber can find a Midway Flag, a magic gate, and a Launch Star. A 1-Up Mushroom can be found as well over two yellow platforms.
Dirt Tower Planet
This planet is similar to the starting planet, but it is covered by gray dirt and has only a tower, which gives the planet a pear-like shape. Mario uses the Drill to bore the ground and go to the hollow center of the planet to find a lot of Coins. Inside the planet there is a hole where Mario uses his Drill to go to the top of the tower.
Digga-Leg Planet
A small cylindrical planet made of dirt where the boss Digga-Leg lies. Stepping on this planet, Mario must move to the sides like in a two-dimensional environment during his fight with Digga-Leg. Some black and yellow security bars decorate the planet.
Levels
Digga-Leg's Planet
In this level, Mario arrives in the starting planet. The plumber must find a Drill to bore the surface and travel across the planet to reach one of the towers where a Luma awaits to be transformed into a Launch Star. Taking this Launch Star, Mario lands in the Drill Zone Planet, where again he must find another Drill to reach the high towers of soil to see another Launch Star and also a Comet Metal. The plumber then arrives in the Steel Ring Planet, where he can save the level, taking the Checkpoint Flag and get the Launch Star to go to the Dirt Tower Planet. There, a single tower must be reached with the Drill. Mario has first to go to the hollow center of the planet and find the spot that leads to the tower. The plumber takes the Launch Star there to go the Starshroom. The Red Toad of the Brigade points to the plumber the next planet he will visit. Also, a Flag can be found underneath the spacecraft and a Launch Star over the Red Toad. Mario finally arrives in the planet where Digga-Leg is to battle against the huge robot and get the Power Star that lies in it.
In this level, Mario must find all the Luma that help him to get to the other planets, turning themselves into Launch Stars.
Sliver Stars Down Deep
In this level, Mario need to use the Spin Drill to dig underground to find the 5 silver stars.
Digga-Leg's Daredevil Run
This is a rematch against Digga-Leg with only 1 health.
