The Earth Dimension is the first dimension that Mario visits in Super Mario 3-D Galaxy. It's very peaceful, with long stretches of grassy hills, bouncy blocks and small caverns. Very few Goombas. The main boss of this dimension is Iggy Koopa.

Once the player has beaten all the stages in a galaxy, the Bonus Challenge is unlocked.
