All 120 Green Stars | Super Mario Galaxy 2

The Green Star hunt opens after collecting all 120 regular Power Stars and defeating Bowser again. There are 120 Green Stars across the original 48 galaxies; Grandmaster Galaxy has none. Each linked chapter gives the exact numbered detours alongside its normal walkthrough.

Select the numbered mission

Choose Green Star 1, 2 or 3 from the mission screen. A star may use the first or second normal mission’s layout, so check the opening instruction before following a route. Collecting the regular ending star does not award the green one.

Use the chime and camera

The sound becomes a useful location clue when the star is behind a wall, below a ledge or high above the normal route. Rotate the camera from safe ground to line up a jump. For stars over a void, collecting the star ends the attempt immediately; the risk is missing the target during the fall.

Completion check

Add each galaxy’s Green Star total to its regular-star total on the mission screen. A galaxy showing an unfinished slot is your next return destination. Once all 120 Green Stars and all 120 regular stars are complete, continue to Grandmaster for the last two stars.
