Cheats for Super Mario Galaxy 2 for Wii

First you need 2 players, you go to the Suppermassive Galaxy in World 4. When you get to the part where there are 3 big turtles player 2 freezes the first turtle then P1 goes all the way around and jumps on the last turtle, Then Mario or Luigi start getting ALL 99 lives without even moving they just bounce!

In order for Toad to upgrade you need to collect more star bits about every 1,000 star bits he up grades.

When you get to World 4 the first Star you get in the first galaxy named "Supermassive Galaxy" the first star you go after is named "Huge Trouble with Big Wigglers". What you do is when you get to the tv that says how to do a long jump, before you watch it, do the long jump and get the 1-UP and long jump back to the tv and collect any star bits around you that you see. Now say yes when the tv asks if you want to see how to do the long jump and when it is done you'll see that all Star Bits and the 1-UP you just got are back. Now just keep repeating until you have the desired amount of Star Bits and 1 UPs. I think you can only have 99 at a time but it may go higher.

To unlock the Grandmaster Galaxy in World S, collect the 240 Stars (120 Gold + 120 Green). This 2D Level will check your Yoshi tongue-slinging skills. It has a Comet Medal and a single Star to collect.

In the Tall Trunk Galaxy, get “The Flotacious Blimp Fruit” star to unlock Luigi for play on certain levels. At the starting of level, you can talk to Luigi to control him. Hit the level and you will unlock a time trial “ghost.” If you beat the game, then a door will open on spaceship Mario’s forehead from right under the main plain platform. Enter this door to transform into Luigi and play any level as the clumsier bro.
