Good Egg Galaxy

The Good Egg Galaxy is one of the first galaxies that Mario will travel to in Super Mario Galaxy. This galaxy features multiple stars, some required and some hidden. Finding a certain amount of stars will lead you to the next galaxy. Bosses here include the Prehistoric Piranha and the Gooper Blooper that is engulfed in flames.

The galaxy features a wide-range of different types of planets, from the one that resembles a Yoshi Egg to another that takes place in one appears to be an oversized transparent pill. The planets are usually grassy or rocky, and often times you find a black hole in the middle of some, indicating that you shouldn't attempt to go underneath this particular planet, as you would be sucked in.
