Lots of 1up's

If you need a decent sized boost (8) to the amount of lives you have in the game, then try this 1up loop.

Watch the video to see it in action or read below:

Die during the credits!

Yes. You can die during the credits! First, you need to have all 120 yellow stars. Now beat the game and wait for the credits. If you have the 120 stars you will get a bee mushroom during the credits. Get it and then in the scene with all the snow, immediately start flying toward the camera. DO NOT hold the fly button instead use it in bursts. Hold for about a second let go for about half a second and repeat. When your fly meter runs out... TOO BAD! You have died in the credits! The screen will go dark but you will still here the page turning. In the very end you will see the "The End" screen but behind it will say "Too Bad". The End Too Bad!

how you get luigi

you get luigi by getting a amount of stars.then at some part of game,you get a letter from luigi and you need to find the L on the starship. go to the back of the deck,it's where lubba is and you will find the L.

Play as Luigi in Any Level

To do this defeat Bowser at Bowser's Galaxy Generator for the first time and then check the Mail Toad for a message from him. Then search for the L on the Spaceship and enter it you will become Luigi. Or alternately, collect the Flotacious Blimp Fruit star in the Tall Trunk Galaxy. When you have this item you will be able to talk to and control Luigi at the beginning of certain levels.

The lumas inside Starship Mario's head (go through the pipe next to the ear)and lumas will be inside. This is my first hint so don't be messed up.

30 Power Stars - 1st Luma (5 Mushrooms, 3 Mushrooms, and I don't know what else)

60 Powers tars - 2nd Luma (It's just like the first one, but the items are better)
