| Super Stomp | 100% | |
| If you want to do a specialized stomp with Mario or Luigi, try the following. When you jump, before you press the Z button to do the Ground Pound, spin by shaking the Wii controller. As you are spinning, you can then press the Z button. The result? A stronger stomp that will actually track the enemy and follow it, kind of like a heat-seeking missile! | ||

| Easy Star Bits in Rolling Green Galaxy! | 67% | |
| I've figured out a way to get a lot more star bits in the Rolling Green Galaxy! (The Rolling Green Galaxy is the one with the bal that you have to balance on for the whole level.) You have to have 2 people. Go in the Rolling Green Galaxy. Player one gets up on the ball as Mario. Player 2 (the other star) collects all of the star bits! Once you get to the place with all of the green grass and ? Coins and holes, You can get tons of star bits! Player one gets the ? coins and then gets to the safest path. Player 2 collects the star bits! It makes collecting star bits in this stagea lot less riskier! Glad I could help! :) | ||

| Extra lives | 67% | |
| Where the toads are making their spaceship, there is a life in a crate. This is renewed whenever you go into a room/ observatory, so keep going to the crate, then the nearest room, and back out again. It's slow, but you can get as many as you like! I assume you can do this for any other of the free lives around the observatory as well :) | ||
