Silver Chomp Grudge Match
Jump on the ball and roll with it on the rocky platform into the circle to be catapulted to the next planet. Roll straight along the Star Bits until you reach green brush. Here the key is hidden in between to roll into the next hole. Follow the approaching platforms extremely carefully and drive up with the colorful platform. Then color all the bottom plates yellow so that you are maneuvered through the entrance to the next hole.
Touch the Checkpoint Flag and quickly grab the Comet Medal before sawing off the wooden floor underneath. Then always follow the path straight ahead and finally crash the silver Chain Chomp off the platform. Just always roll with strong steering movements against the monster. As a result, a further inlet appears. Roll into the pink hole and grab the Power Star at the top of the pole.
Masterpiece Speed Run
Select this challenge when the Prankster Comet appears.
For this comet star, you have to complete the exact same course – but this time within 120 seconds. So do not pay attention to the details, but race with the ball through the planets. This time the key is not found on the green but on the blue brushes.
Comet Medal
On the long wooden cylinder before the Homing Chomp arena, steer the Star Ball through the medal while the saws are cutting the course. Avoid waiting until the supporting wood disappears.
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
Reach the rising elevator in Silver Chomp Grudge Match. Move to its far left before it starts ascending. Follow the line of Star Bits at that side to meet the star during the ride.
Green Star 2
At the Homing Chomp arena, the star is high near the upper-left edge. You can steer the Star Ball into it, or first knock the Chomp out, dismount and use a backflip followed by a spin for a more controlled jump.
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.
