You get every green star.
Find the THREE GREEN LUMA STARS and they will take you to that funny little colourful planet in the observatry via the green sling star. There, three challenges await you- Loodeswoop Galaxy, a seemingly IMPOSSIBLE manta ray surfing course, Bubble Blast Galaxy, a VERY HARD bubble Mario galaxy with electric fences, lasers and bulletbills, and Rolling Gizmo Galaxy, a PRETTY MUCH IMPOSSIBLE version of Rolling Green Galaxy. There also is home to the Grand Finale Galaxy.
Super Mario Galaxy 2 has 242 stars in the game, just like the prequel. However, the green stars only appear after you get 120 stars.Green stars appear in every galaxy (except Grandmaster Galaxy). Usually there are 2-3 green stars in a galaxy. Now the objective is to find the hidden stars in the galaxy, which can prove quite challenging.After getting all the green stars, you end up with 240 stars, which will unlock the final galaxy: the aforementioned Grandmaster Galaxy. There are 2 stars in the galaxy, which will bring the total to a satisfying 242.So in summary, you can only get the green stars after having 120 stars.I hope that helped!- Ryanthelion
