Hint: Defeating O2:
After you get all 100 shards, you will have to defeat the Ripple Star Boss again. If you do, you will go to the next star. To defeat O2 (the next Boss) keep shooting his eye -- you will automatically get a gun that shoots shards. After awhile his head will face the screen. Keep shooting his halo. If you shoot it long enough, a large spike will appear from under him. Do not stop shooting it. Repeat this approximately three times to defeat him. You can also shoot the red part of his wings off when he flaps them in front of his face.

Hint: Free Star Piece or Treat:
Return to the beginning of most levels to find a Star Piece or Treat.

Get under an enemy that you want to defeat. Then, jump under them and they will freeze for a few seconds. Jump under them two times in order to defeat them.

Hint: Protection from dynamite:
Hold Down when using dynamite to protect yourself from the explosion.
