Super Mario Galaxy Tips

Grand final galaxy area.
So many people had trouble finding the grand final galaxy including me so i am here to put the area of it. after you get all the 120 stars with Luigi/Mario and beat Bowser after obtaining them it says "Grand final galaxy now open" or something similar to that. the grand final galaxy is on the planet where you get after getting the 3 green stars. when you land on it there should be a green Luma in the middle opposite side of the tube and talk to him, he will send you to the grand final galaxy.

Have Fun!
