Silver Stars on the Cyclone
In this level you have to collect all five Silver Stars, which were distributed quite easily. Take care of the Thwomps and hide in the holes of the Tox box. With the circulating stones, you jump onto the elongated plates, which always jerky to the right and left. This is how you get to the Comet Medal.
Tox Box Speed Run
Make your personal fastest way through the galaxy and collect the clocks to create this Power Star within the time limit. You need perfect timing here in order not to waste unnecessary time. You have to be able to memorize the course practically so that you can progress quickly enough.
Comet Medal
Ride the circulating stone platforms to the long slabs that slide sharply left and right. Time a jump across those slabs to collect the medal without being pushed into the void.
Green Stars — unlock requirement
Collect all 120 regular stars and defeat Bowser again to unlock the Green Star hunt. Choose the corresponding Green Star mission from this galaxy’s mission screen. Follow the detours below rather than collecting the normal mission’s ending star.
Green Star 1
Around the course’s halfway point, locate the high star above the moving route. Build a triple jump from a safe stretch, then spin at its peak. Time the approach so the moving blocks do not cut off your run-up.
Green Star 2
Near the ending, look beyond the edge towards the star over the black hole. Long-jump from the nearest safe corner and spin to extend the reach. Check the direction before committing because there is no platform underneath.
Check each numbered Green Star on the mission screen after collecting it. The routes finish immediately when the star is touched, including stars suspended over a gap.
