This mission involves Mario fighting Dino Piranha. It had a more realistic house, a pine tree instead of a regular tree, and no stairwell leading up to the twisty walkway. In early versions of the game, the planet looked drastically different. Finally, in 'King Kaliente's Battle Fleet', the Launch Star is on top of the house on the sunnier side of the planet and leads to the Tropic planets.

This leads to a maze of three planets, being the Tropic planets and the Egg planet. In 'A Snack of Cosmic Proportions' and 'Purple Coin Omelet', the Launch Star is located at the top of three Pull Stars at the end of a stone walkway next to the tower. In the missions 'Dino Piranha', 'Dino Piranha Speed Run' and 'Luigi on the Roof', it can be found at the top of the tower and leads to the Boulder planet. In various levels, there will be Launch Stars placed in three different locations. At the end of the side, there is an Electrogoomba.

In the center of the planet, there is a giant tower with a special side without gravity and allows Mario to walk up it. The other side of the planet has many dead trees with Star Bits on their branches and a constant rain of them coming down from above. The game cover of Super Mario Galaxy also features five planets from this galaxy. The galaxy's level select model has a hemispherical grassy dirt planet that is not found anywhere in the galaxy. The galaxy went through a few revisions before its final version, mostly involving planets getting redesigned or removed, as seen in the GDC 2007 Trailer. The original E3 demo and gameplay footage mostly featured segments from Good Egg Galaxy, along with a mixed-in level from Space Junk Galaxy. The name of this galaxy is most likely a pun on 'good egg', which means a reliable and pleasant person. Good Egg Galaxy has the most planets out of any other galaxy in the two Super Mario Galaxy games, having 19 accessible planets in total. Dino Piranha and King Kaliente are the bosses in this galaxy. Most of the planets in this galaxy are lush and grassy, with some of them resembling food. It is the first level within the Terrace dome. Good Egg Galaxy is the second galaxy in Super Mario Galaxy. The starting planet, the Boulder planet, Dino Piranha's planet, the Egg planet, an unused grassy bowl-shaped planet, and some small asteroids
