Go past the bars in the cell Luigi's not in, and then lose your boo form. If you lose your Boo form, it's alright, just get the Boo mushroom in the corner. Get the Boo to see you, (I hate romance) let it chase you, and then lead it to the chandelier light. Inside, Luigi is locked up with a Boo on guard. Light is their weakness so look for a lit chandelier. Go inside and beat all Boo's in the Haunted Mansion. Spin-killing or using other methods will usually result in a few Star Bits. By jumping on an enemy, which is usually the more difficult way to kill most foes, a Coin will appear. When you fight most enemies, you can control what comes from their dead bodies when defeated (a sort of 'sacrifice'). This may be an obvious hint, but it's one worth stating nonetheless. When the countdown timer starts as you are racing Cosmic 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 Cosmic Mario. Mailtoad addresses that problem, then gives you 20 lives. If you talk to him when he has mail, you get a letter addressed to Mario. When you start with Luigi, after you get a couple of stars, look for the mailtoad. If you havn't gotton all 120 stars with Mario, don't read this.

When you get them all, the sand dissolves and the star is at the bottom. Inside the planet you will have to get 5 transparent stars while the sand level rises and falls. Feed it 20 starbits and it will transform into a new planet.

#3: Go to the Dusty Dune Galaxy and do the 2nd star challenge. Go in the pipe and have a Bullet Bill break the other glass and get the star. #2: Go to the Buoy Base Galaxy swim under water and have the fish Bullet Bill break the glass with the pipe inside. After you blast the cage with a Bullet Bill he will give you a green star. #1: Go to the Battle Rock Galaxy after you get Luigi's letter asking to go find him. Yes there are Green power stars in the game. Instead of pressing A+B at the main menu, hold A+B and 1+2 to unlock two bonus stages. Keep doing this until you get as many lives as you want. 2) Go inside the Kitchen Dome (you don't have to enter any of the galaxies)
