In order to start collecting Green Stars you will first need to find and collect all 120 normal Power Stars, you then need to finish the game by beating Bowser again for the Green Stars to show up.
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
the trial galaxy rock is on top of the observatory (or around it). you have to get the three green power stars and a green launch star will appear use it to get to the trial galaxy rock.
When you get 120 stars you see a green comet and scatters 120 green stars

when you go into the castle.jump on the block and you will see the comic medal.and they make comics appear. if you get all of the stars and comic medals. you make green comics appear in all of the galaxy!

First, you have to beat the game with the regular 120 stars. After that, green stars will appear. Once you have gotten all 120 green stars you will have a total of 240 green stars. After the 240th star, the Grandmaster Galaxy will appear (The Ultimate Test). After you have beaten The Ultimate Test, you will have to collect 9999 star bits to unlock the Prankster Comet (The Perfect Run). Hope I helped!(:
To get green stars, you go through each level and look for green stars. You can also listen for the star "sound."
yes there is you might need help from a friend and walkthroughs/cheats.
