Super Mario Galaxy 2 Green Stars - Supermassive Galaxy Star 3

Green Star locations in Mario Galaxy 2. To unlock Green Stars you first need to collect the first 120 normal stars then beat the final bowser fight again. Alot of this is just me playing around and going by memory so if I don't do perfect in a world you can just skip to the last 10 seconds or so to see the stars location.
