Today we will be giving you a complete run down of all the unlocables in the game and how to get them so lets get started. Also check out how to get the Infinite Lives and Infinite Flutter Jump.
Unlockable: Profile Crowns
Perform the following actions to win the image of a crown next to your save profile.
* Silver Crown – Get 120 Stars
* Gold Crown – Get 240 Stars
Unlockable: Alternate Ending
Collect 120 Stars to see an alternate ending cutscene with Rosalina reading to Lumas and discussing Green Stars.
Unlockable: Grandmaster Galaxy
Collect 240 Stars (120 Gold + 120 Green) to unlock the Grandmaster Galaxy in World S. This 2D level will test your Yoshi tongue-slinging skills. It has a Comet Medal and a single Star to collect, pushing your star count to a whopping 242 Stars!
Unlockable: World S
Beat World 6 and you'll view the game's ending … but it's not over yet! You'll unlock an entire new world, World S, as well.
Unlockable: Luigi
Get 30 Stars to unlock Luigi for play on certain levels. You can talk to Luigi at the start of a level to control him. Beat the level and you'll unlock a time trial "ghost."
Beat the game and you'll be able to walk into a door on Starship Mario (on Mario's forehead, just below the main area) and transform into Luigi to play any level.
Unlockable: Staff Ghosts
Beat the game after you get the 120 Stars and you'll unlock 120 more Green Stars to collect! Green Stars are stars located at tough-to-reach locations in the previous galaxies. They have NOTHING to do with Luigi.
Unlockable: Green Stars
Beat the game after you get the 120 gold stars and you'll unlock 120 more green stars to collect!
Hint: 1-Up Mushrooms on Spaceship Mario
You can collect several 1-Up Mushrooms on Spaceship Mario. As you collect stars, the following 1-Up options will appear on Spaceship Mario.
* Grab Yoshi off of the "nose" and use the star pegs to swing up to a hidden island with 10 fruit. Eat them all for a 1-Up.
* Grab a Cloud Flower and make platforms to reach a 1-Up on a cloud high above.
* Spin into the random item block for a chance at a 1-Up.
* Near Mario's left ear (your right) is a warp pipe that takes you to a 1-Up minigame. Feed the Luma to spin a number of random item blocks for a chance to win 1-Ups.
* Talk to the Gearmo Robots when they show up on the planet to receive 1-Ups.
Hint: Super Ground Pound
Jump, shake the Wii-Remote to spin and QUICKLY press Z to perform a super ground pound. This move will allow you to hone-in on enemies below you; a heat-seeking butt-stomp, if you will.
Hint: Luigi on Title Screen
Exit the game while playing as Luigi instead of Mario and you'll see his face on the title screen (as long as you chose Mario's for your default profile face).
