Unlock Bonus Stages in the Demo
Instead of pressing [A]+[B] at the main menu, press and hold + when pressing [A]+[B] to access two additional stages.
Unlock Hidden Character
Get all 120 stars, and then return to Rosalina (on the Comet Observatory). Request to fight Bowser again. Finish the credits and you will get a message saying that Luigi is now playable.
Grand Finale Galaxy and Star 121
Collect all 120 stars with Luigi and then beat Bowser. Doing so unlocks the Grand Finale Galaxy, which is the Star Festival seen in the beginning of the game. Collecting the 100 purple coins in this galaxy will get you the final star.
Spin in mid-air and press [Z] to do a homing attack on the nearest enemy or breakable item.
Starting Boost When Racing Shadow Mario
When the countdown timer starts as you are racing Shadow Mario, hold [Forward], then as it hits 2, hold down on [Z] to crouch, and when the race starts hit [A] right away and you will turn yellow for a few seconds and get a really good boost that will put you way ahead of Shadow Mario.
The Grand Finale Galaxy (a secret galaxy that can be unlocked after 120 Stars are gathered with both Mario and Luigi) holds another secret -- once this final Star from the stage is acquired with both Mario and Luigi, you will be able to see your death count on your save file. You can now see how many times you died while playing the game with both Mario and Luigi.
All Coconuts Become Watermelons
Collect 9,999 star bits in the hub, and all the coconuts in the game become watermelons.
Once you have unlocked the Rolling Gizmo Galaxy as one of the trial galaxies go into it's level. Walk past the ball and get on top of the metal cubes. Do some fancy wall jumping onto the bridge. Once on top, go to the edge and pan the camera down. You will see a Zelda Rupee made out of star bits!
