In order for this cheat to work,you have to take a feather(most important thing)and go to Donut Plain 2
(the second stage)then,go to the place where you found
the key and the keyhole and unlocked the Green Palace.
take the blue shell and climb up the plant ladder.Go to
the side and make the shell float up into the air with
your cape(make sure the shell won't fall).As you float the shell up,it will give you scores first(100,200,400,
800,1000,2000,4000,8000 and 1up).The shell sometimes falls and you have to start all over again.But if you
manage to time your shell,it give you 1ups in no time!!

If your starting the game,find & finish all areas,
fortresses,castles and secret areas to unlock the cheat.
You will see a short movie that Mario & Luigi are replacing shells to Mario & Luigi head costumes that
Koopas are wearing(Not the boss Koopas).Your enemies will change too.The islands that you completed will be
change into many different colors.I completed this cheat twice.I hope that my cheat will be useful!!

Here is how to get a lot of lives! First get the feather on you and in that storage box. Then you go to yoshi's island and keep flying until you find a moon. It gives you 3 level ups and also there is another way!
Here is another way to get a lot of lives go to the donut plain 1 and go into the secret area where you can get the feather...get it and then you run up, hit the coin meter and keep flying this should give you about 6 lives.
These cheats have been tested and I got 140 lives by using these cheats.

At the first Ghost House, have a feather. Go backwards instead of forward and fly up to the sky. Continue on the platform in the sky until the end of the level where there will be a new exit. Go through the exit to unlock an extra level which you can stock up on unlimited mushrooms, fireballs, feathers, lives, and Yoshi.
