Hi guys this is my first cheat so here goes. This is for all the people who need to get something really high! Just do a triple jump than flip at the top of your flip! Ta-the!
Shortcut #1
Where the luma says he'll become a sling star to bring you to the launch star, you can also backwards somersault to the launch star.
Shortcut #2
Instead of entering the house, you can backwards somersault to the roof.
Shortcut #3
On the big star with blue star chips, you don't need to get any star chips, you can long jump to the star.
1) Whenever you need to go on the house's roof, you don't need the pipe. Backwards somersault and you can reach the top.
2) On "A Snack of Cosmic Proportions," on the big launch star-looking thing, long jump to the star and you can get it.
Don't say "These don't work, they're impossible!", I've done them both before. Hope I helped!
Go to Dreadnought Galaxy, Star 2 (Dreadnought's Colossal Cannons), get to the checkpoint before you start the platforms and avoiding cannons. Then, when you jump to go on the upside-down platform, don't TOUCH IT, just go in between the small platform and the moving one. Your character will fall through, but not die because gravity keeps changing, stopping him from falling. WARNING: I cannot find a way out of it, so you will have to retry the level.
In the observatory grounds use the red star which enables you to fly(unlock gate first and do red luma request). Then fly towards the gate and underneath is a one-up. Hope it helped!
When in the main area (or starting area) use a light teleport on yoshi but fire his tounge at the yellow toad. His tounge should stick to it.
Okay. Go to the dusty dune galaxy and go to the 2nd star. After you go through the first launch star go to the bottom of the planet. The hungry luma will want 20 star bits. Feed him and he will transform into a pyramid planet. Collect all five silver stars inside of it and the green star will spawn at the bottom. Grab it. Peace.
Okay. If you go to the fountain, before you go to the teleporter go to the blue luma go to the corner jump down and when the bubble forms around mario you should be able to see him through the ground. (I tried it and it works.)
1.under gate way galaxy
2.on tip top of observatory(note:you need flying mario)
3.garage--wooden box
4.under library(note:on that green rotating thing)
Go to the Deep Dark Galaxy. Jump in the cannon and shot to the tree right to the planet. You fly into another planet. Remove the bolt and collect the coins,you needn't all. While you are running hold Z and press A. Then you are making a giant jump and the planet is shrinking.
how do u run caz i keep on losing on that thing where the garbage is and u have to throw the bomb on the garbagae?
go to deep dark galaxy and shoot over to the shrinking planet and spin out the screw.when its shrinking coins will apear.long jump and try to get them.mario will go around the planet and wont touch the ground its a fun thing to do.enjoy

You know that the firepower is a limited time well not any more just pause the game and just press 1and2 together and you will hear no music.
you now that your firepower is limited time not any more just puase the game and press1and2 and walla no more limited firepower unless if you get hit
During gameplay use a second Wiimote and although a second player will not appear the second Wiimote will have it's own pointer giving the other player the ability to assist in collecting items and helping Mario's jumps.
This will happen when you have collected 9,999 Star Bits in the Hub.
When you are flying, hold a to float where you are
When you unlock luigi, when you play as him, the 2nd luigi (the one you rescue) will be taller and skinnier than your luigi!
If you have gotten 121 power stars with Mario and Luigi your head will sparkle on the select file screen.
So if you want to get Green power stars do the following.
1st Green power star: rescue Lugi in battle rock galaxy.
2nd Green power star: in bouy boue galaxy go under water and destory the glass cage with a under water bullet bill and go into the tube and destory the 2nd glass cage and there will be a green power star
NOTE:There are three Green power stars but the 3rd green power star is unknow to me...also please rate this cheat
So here is a special butt stomp. First you need a spin luma to do this stomp. Now get near a enemy then jump then spin and do a butt stomp and then you will hit the enemy and you are in a place where you can't hit the enemy. Thanks for reading the cheat.
NOTE:Please RATE or mario will cruch YOU!!!!!!!!!!!!
You can triple jump if you have two players, do a backflip jump, then spin Mario, then tell the second player to click Mario with their pointer, you will do a triple jump, Please Rate!
Have you ever wondered what the Red Luma's secret was? Well. I have your awnser. The red Lumas have a special power you only can use after beating "The Gateways Purple Coins" Level in the gateway Galaxy. Afterwerds you can use this power anytime at the comet observatory. How to use. 1.You must get the red star by the Red Luma or by the garage. 2. Jump with A. 3.While in the air spin. 4. You should be flying. 5. You can steer with the nunchuck. 6. Hold A in the air to hover. Luke .s over and out
First you beat the game as mario. Then become lugi and beat the game then when you look at your profile it will say how many times you died as mario and lugi
After you beat bowser once collect the remaining stars then beat bowser again and you will be able to play the game as lugi
Well I have been seeing this question always being asked.The location of the the final galaxy is underneath the trial galaxy.It is that place were all the green pipes are which is underneath.The green luma says :Will you like to go to the final galaxy ?You say yes collect the purple coins which are easy and your done
If you are in co star mode then p2 prees your star on mario to make him jump but at the same time p1 prres a (requires practes)
In one of the Bowser levels, look for the things that shoot fire. Look closely at them. Those things that shoot bubbles, look at them closely. That Mole Boss that shoots you with water, Look closely. If you are looking close enough, you will see that they look like FLUDD from Super Mario Sunshine.
To paralize enemies,just get a friend to control another wii remote,and when he/she presses A and hold it on a enemy,it will stay paralized!
PS:This cheat does not work on bosses!
Happy Cheating,Lucario987

Go to the shrinking satalite galaxy and collect every star bit and then collect the life and die.Repeat doing this till you have enough star bits or lives than finish the level
On the garden maze where the bunnys are the main inhabatants (i forget what it's called), there is an easier way to catch the bunny to get the star.I thought of this cheat because it's really hard to catch that bunny, so all you really have to do is do a longjump when your in front of him, by pressing R+A.
Make sure that the bunny is not going to turn and that your facing him. It worked for me the first time. If you do, you should be able to catch him.
Once you get all 120 stars with mario you can play as Luigi!! If you get all 120 stars now you can get the 121st star!!!
This isn't exaclty a cheat but more of a glitch. You need to have the Machine Room though. Move to the left just a little bit and fall off the platform. Do a Ground Pound straight into space, a bubble will form around Mario and he will be lifted back to where you started. During this the screen will flip for about two seconds. (Note that this may not always work.)
If you are swimming and are tired of shaking the remote all the time this hint will help. For it to work you must be under the surface, but so that the camera stays above the surface of the water, (it should have an air meter next to Mario) shake the remote and you will get an extra long, boost of speed.
Hope I help with your surface swimming issues!

Hey guy's my name is Rewite this is my first cheat so I hope you enjoy it.
Alright in Deep Dark galaxy I think. On the third level the toad's will be roasting some mutton. There will be a cocanut next to the fire. Spin and it will hit the fire and also blow it out. Then pops out a coin. I'll be back... To make more stupid cheat's! -Rewite
Okay
Click on a save file and point at the spining save file head. Spin the head in one direction by going in a circle through the head then over the head. After spining the head really fast, the head will close it's eyes. Spin it so it is facing you. Try to keep it still. The head will start to blink and open it's eyes again.

To get the red star you must unlock the garden room then go half way up and you will see a house go into it and you will be on another planet. Then go and talk to rosalina and then luma will come and ask you to collect 100 purple coins. If you succeed, you will get the red star.
To do this collect all 120 stars, then go to Rosalina at the comet observatory, and ask to fight Bowser again. When you win you see an alternative ending to the game and unlock Luigi ^_^.
These cheats will help you on your adventure.
Super Spin Attack:
You press and hold [Z] then spin.
Somersaults:
You should no where the lives are after you gain access to the Kitchen, then while you're there, Hold Z and Jump, do this as long as you want until you fall off the ledge.
A "Cat's" Three lives + 5:
1. In the box in the Garage.
2. On one of the green floating panel under the Bedroom.
3. Under the Kitchen "Somersault Area".
4. (The 5) Hold 1+2 right when Pressing A+B on the home screen and go into a file and you will have a 75% chance of the Mailtoad to give 5 lives, and a 5% chance of him giving you 50 lives.
Luigi's help:
After beating getting all 241 stars..
For one of the cosmic races(the one in freezflame galaxy) where you have to skate, run through it like normal until you are near the Power Star. There is a blank space in between this and the Ice Blocks. It is risky, but it helps especially when you have Luigi. This is a shortcut that helped me out with Luigi. Since Cosmic Luigi races are harder, it only fits to have shortcuts that make it all worthwhile.
These are all the power ups in the Game
1.1-up mushroom. 1 extra life
2.Bee mushroom(black&yellow). Lets you fly and climb on honey walls touch water or get hit to turn back
3.Boo mushroom(white). You can float and go through walls touch light or get hit to turn back
4.Spring mushroom(silver). Lets you jump really high touch a launch or sling star or get hit to turn back
5.Power mushroom(red). Gives you 6 life instead 3
6.Fire flower(red&yellow). Lets you shoot fireballs when you spin for a limited time
7.Ice flower(blue).you can walk on lava or water or skate for a limited time
8.Rainbow star(rainbow). You are invincible for a short amount of time
9.Red star(red).lets youfly for a limited amount of time (only in garden and the giant ship)
Go to toy time galaxy, level 1. Go to where you see the 2nd spring mushroom. Instead of going strait, go right. Keep going until you see the pipe. Youll see an oversized blue pencil with a trail of star bits coming from the point. As you go down the pipe, collect some of the star bits. You'll end up in a cylinder room. Bounce around for a little bit until the star bits come flying out of the dark matter around your room.
Ya know those vines you spin on.WELL some are fake!Shocking isn't it?Yes some throw you into a black hole.find them and DIE!ya know?
The Locations of the three green stars are
Battle Rock Galaxy: Get it by saving Luigi
Buoy Base Galaxy: Using a bullet bill destroy the other glass cage and go into the pipe.
Dusty Dune Galaxy: Feed the hungry Luma and go to the new planetoid and get it on top of the stone platforms.
1. The first bunny is under the snow!
2. The second bunny is in the tresure chest at the very top to open it first hit all the blue panals and turn the yellow then the bottom will open (lots of bunnys get traped in there)then get the fire flower and melt the snow men a shell will pop out!grab it and open the chest!
3.the last bunny is in a snow men grab the fire flower and melt it. Then grab the bunny!
Thats how you get the star!
When you are at the golden leaf galaxy take a sudden turn at the first log then you will see a sling star go into it and launch up up and away! P.S. When ever I use it I lose so don't try it!
ALWAYS feed hungry lumas because if you feed it it will turn into a planet or a launch star that will eventualy get you a star! P.S. I am not talking about lumas near places like the terrace. I am talking about the ones at a galaxy.
To get ahead of Shadow Mario you have to be very close to hime and keep on long jumping and then you will suddenly get ahead. Trust me I beat him in the golden leaf galaxy and beat him in less than a teth of a second! P.S. Please rate this

If you've unlocked the Garden dome, and have Deep Dark Galaxy, go to the first mission. Here's a list of all possible 1-ups.
1) Jump your way on top of the Starshroom at the beginning. A 1-up is at the top.
2) Attack the blue crab by spinning into the front of it, then go around and hit his back. A 1-up will appear.
3) Jump into the water, and get the shell, and swim to the left side of the lake (left when facing the lake from the metal bars at the entrance of the cave). Throw the shell at the chest, and a 1-up will come out.
4) Attack all the enemies on the beach, and you'll get tons of Star bits. Get more and more, and every 50 star bits, you get a 1-up.
5) Take the cannon, and aim yourself at whichever planet you want. Read below before firing.

When you have beaten Bowser with Mario go to the gate and step onto the little castle. Agree to help Rosilina protector of the cosmos and she will leave you with a red powerup luma to help you. Collect ALL 100 purple coins and you will get a red star which will give Mario red and black clothing and the ability to fly.
First you have to start out as a regular ground pound ,then right when you pound youspin with it.
Ihave 101 stars and have a few hidden stars to get, have gotten all the green lumas and passed their levels and passed all the cosmic comets. Do I have to search all the galaxies that don't show that they are complete (no crown) to find more hidden stars or are there more levels once I ask Rosalina to go to the center of the universe? The general concensus seems to be 120 total stars the first time.
When you double jump,shake the wii remote to get a boost
You have to unlock the kitchen observatory. You take mario under the step to get to the kitchen. There should be a life mushroom there. Then run into Rosalina's library. Then go back out. Go back to the place where you found the life. There will be another life there. Back to the library. Back to the life. Ect.
P.S: If it is your first time in the library, you have to listen to Rosalina read a chapter of a storybook to the Lumas.
If you are about to get a game over on a level, then you press pluss on the Wii remote and go back to the observatory and do the infinite life cheat.
Try it out!
1.First you need to go to sling pod galaxy (this is a lot easier if you have another person to collect starbits).
2.Then you need to get to the check point (past all of those spikey balls).
3.Before you sling to the next sling pod, look for a mystery coin (the big coin with a ? On it) then sling to it but before you get the coin grab on the blue star. This will cause you to grab the ring and still live.
4.Then you follow th path of starbits till you see this huge arrow made of starbits. Collect them and then fall. When you go back to the stage you will still have your starbits and you will be at the place with the mystery coin.
5.Repeat steps 3-4 until you have 999 starbits (thats the maximum starbits)then get the star.
OK I tested this and found out it worked. It's not much but here it is. When you see a goomba ( or some other enemy) if you want star bits spin (1-5) and run into it or daze it with a star bit and then run into it. If you want coins (1) then you have to ground pound ( jump then [Z] I think)or jump on the enemy.These are the only ways to get coins.

At the very beginning of the game, keep on collecting star bits and go back to the square. The star bits will be in the same place. It is a good way to have alot of star bits and one of the easiest methods I use.
Bonus Stages (Demo version)
Instead of just pressing [A]+[B] at the main menu of the demo, press and hold [1]+[2] when pressing [A]+[B] to access two additional stages.
I have 4 cheat for you.
1.You can colect star bits useing the blue star on your TV.
2.In the VERY start of the game,DON'T go straight to Peach's castle.Stay and get all the star bits you want.
3.If you have another Wiimote,you AND a friend can colect star bits together.
4.Use cheats 1,2&3 together.
I don't know if this is a cheat or not, and it doesn't do anything special, but I just wanted to tell if no one else knew. Ok, to do this, jump into the air (any height doesn't matter), and spin. Right after (immediately, instantly, super fast right after), press Z. Mario will look like he's in crouching position, for 1 second, then go downward for a ground-pound. It looks cool, but I don't think it does anything.
In Gateway Galaxy, when you do the first mission, which is Grand Star Rescue, on the yellowish planets with wires wrapping all around it, do you see those pink pyramid-shaped objects? Spin against them, and a giant stun wave will blast throughout your screen stunning any Goombas nearby (it can most likely stun more, but Goombas are the only enemies there).
This is pretty useless, except for in the Ghostly Galaxy to try and jump across the trees. As Fire Mario only, you can spin/throw fireballs three times, but you don't get as much of a jump boost, like the regular spin. You can only get farther.
Trying to get on a ledge that's high? Or something in the air not reachable? I have a solution for you!
Required:
-1 wall
-1 Mario
-1 Brown Luma
First, run in the opposite direction of the wall, then do a backflip (press A + opposite direction of the way you are running). You should go double the height of a normal jump. Then, when you touch the wall once you hit the peak of your jump, do a wall kick. You get even higher! Then spin once you've gotten the highest possible and tilt the control stick towards the ledge or item you are trying to get. (Note: You can do the same thing in Super Mario Sunshine, except you don't spin with the Brown Luma, you hover with FLUDD.)
When you have collected the final star with Mario and Luigi so you have the required 120 to unlock the 'Grand Finale Galaxy' and saved the game you can then view your death count on your 'Save' file to see how many times you were killed during the game with Mario and Luigi.
The Grand Finale Galaxy, which is the secret galaxy that can be unlocked after 120 Stars are gathered with both Mario and Luigi, holds another secret. Once the final Star is acquired with both characters in this galaxy, you will be able to see your death count on your save file. This will allow you to see how many times you died while playing the game with both Mario and Luigi.
There's actually 121 Stars in the game, not 120. To get it, you must first have all 120 Stars. This unlocks Luigi. Beat the entire game with Luigi, defeating Bowser at the end. After this, a new galaxy will be unlocked. Finish this final galaxy to get the 121st Star.
Because you start each game with only four lives (after shutting the game off and turning it back on), you might be in need of some extra lives upon rebooting the game. You can usually get five right off the bat from Toad (he'll run around with a letter above his head, symbolizing a letter from either Luigi, or more likely Peach). There are four more strewn around the Observatory that you can acquire, however:
* 1.) On the moving green platform below the core.
* 2.) Under the stairs leading to the kitchen.
* 3.) Right at the top of the observatory. (Once the Red Star is unlocked)
* 4.) Underneath the entrance to the gateway to the stars. (Once the Red Star is unlocked)
If you have a second Wii controller, you can have a friend play along with you. While there won't be a second player on-screen, you will have a second cursor to use. This means that Coins, Star Bits, and the like can be collected by the second player. There's also some functionality in controlling Mario's jumps.
The Grand Finale Galaxy, which is the secret galaxy that can be unlocked after 120 Stars are gathered with both Mario and Luigi, holds another secret. Once the final Star is acquired with both characters in this galaxy, you will be able to see your death count on your save file. This will allow you to see how many times you died while playing the game with both Mario and Luigi.
For every level there is no time limit to get a star. For some stars there is a time limit (such as speedy comets and purple coin comets). When you play with p2 you don't have to hold down B to collect star bits. B, for both players is shooting star bits. When you hold down A for p2 you get a circle around the pointer. That is for stunning enemys but it won't work for all enemys. Also, there are several different power ups. One more thing, thankfully for each stage u don't need 100 regular coins but for purple comets u need to collect 100 purple coins within a time limit.
White: turns you into a ghost (touch light to turn back)
Black and yellow:turns you into a bee (touch water to turn back)
Silver: turns you into spring mario (get hit by an enemy I think..
When you are racing against Shadow Mario hold forward when the countdown timer starts and when it hits 2 hold down on Z to crouch. Then press A as soon as the race starts and for several seconds you will turn yellow and recieve a boost that will leave Shadow Mario way behind.
On toy time galaxy, on the first level, heavy metal mecha bowser, after the second or third checkpoint go to the left, you must be spring mario, go in the pipe and get to the top, try not to break any of the blocks, at the top there is a question mark coin, get the coin and all the blocks will turn into star bits. If you didn't break any blocks there should be 61 star bits. Then go through the pipe and jump toward yourself and if your lucky you will land on a red block with a 1-up mushroom then jump off and do it until you have 999 star bits. You can only have 999 star bits in a level but on the observatory you can have way more.
I have only done this three times and I have 4660 star bits.
To perform this special move which attacks the nearest enemy or breakable object in the game you have to press Z when you spin in midair.
Collect ALL 120 stars with Luigi and beat Bowser, when you've done this the Grand Finale Galaxy becomes unlocked which is the Star Festival you saw at the start of the game. When you have collected the 100 purple coins in this galaxy you get Star 121 which is the final star.
To unlock this hidden character you must collect ALL 120 stars and then return to Rosalina on the Comet Observatory and ask to fight Bowser again. When the credits have completed you will see a message that tells you that Luigi is now available as a playable character.
I have learned a lot more about this game. For one there is no time limit, that's just for the demo. You only have to hold B to pick up crystal shards if you're P2. There's a multi-player mode, but only another Wiimote is needed. He/She can shoot, and pick up star shards, stop Mario for as long as they like to help him avoid things. (Though he can't be moved) Or stop enemies long enough for Mario to hit them. Here are the power ups:
The only one you should find in most levels is the Super Mushroom-doubles Mario's health to six.
The rest are:Black and yellow mushroom-Mario becomes a bee and can fly by holding down A, but if you touch water you lose it.
White mushroom-Makes Mario become Boo Huu (I've only heard that though) and you can float around, and become invisible for ..
At the 'Main' menu press A + B + 1 + 2 to unlock two hidden extra stages in the Demo version of this latest installment in the hugely popular series by Nintendo.
