Get to a part in the game where you fight Birdo. Jump on her head and press B, as if you were picking up a vegetable. You will pick up her Bow. You can either throw it at her, which causes it to appear back on her head, or throw it off the edge or something so she is bald.
When you use the magic potion to get the mushrooms, do not pick up the surrounding vegetables (which are coins in the magic door) immediately. Instead, find the location in each level where there are the most vegetables that are close together. Drop the magic potion and go in the door. Pick up as many coins as possible. Repeat this once, after doing something that will make the potion reappear (such as climbing a vine, going down a pipe, or entering a door).
Find a giant enemy and throw them. Do not through them off a ledge or into an enemy. A heart will pop out of them. You can do this as many times as needed if you do not kill them.
Each time the spinners start in the bonus round, the second symbol in the first slot is always a cherry. If done correctly, you can usually get an average of at least one extra life per coin.
While playing a game, press Select + Start + A + B.

|World 1-1 Quick Ending|
On World 4-1, get the Princess. Go up the vine, but go to the left. Run and fly to a secret door. Go through the door and use the bombs to blow up the wall. Then, jump over the top of the screen and run left.
|World 1-2 Shortcut|
In World 1-2, select Luigi, get the carpet, and fly to the land. Instead of getting the key, pick up the hopping Ninja and throw it in front of the door. Then, prepare a squat jump and wait for him to jump high. If done correctly, you should jump and reach the hill above you. Then, run past the first door and enter the second one to fight the Boss.
|World 1-3 Warp|
At the end of the outside part, there is a vase object. If you carry a red liquid in a bottle and throw it there, you will go down.
Take a potion to the last vase (past the door) and throw it. Enter the new door and then the vase to warp to World 4-1.
|World 3-1 Easy Coins|
In World 3-1, use Toad, because of his lifting power. Fall down the waterfall, onto the platform where the door is at the bottom. Enter the door and get the magic potion. Drop it anywhere where there is a continuous stream of coins. Enter this door, and get as many coins as possible. Go out the door you used to enter, then return, and repeat once.
|World 3-1 Warp|
After you go into the first door, walk into the hole. There is a piece of land with another door located there. After you are in the door, go to the end, then start picking weeds. The red ones are placed at random but are usually near the back. If you want a lot of coins, just throw it where you found it. If you want to warp, just throw it near the vase object.
|World 4-2 Extra Lives|
There is a Giant POW in the level. Use it to kill all of the little porcupines around you. Go up the vine and go back down. Sacrifice your energy to get to the POW and kill them again. Go back up and get the Heart by holding Down for a few seconds and jumping. Repeat the process until you get as many lives as desired.
|World 4-2 Warp|
Take a potion in the second part of the stage, to the only vase. Enter the door and then the vase to warp to World 6-1.

Use the Princess in World 4-3. A castle will appear after crossing the lake. Do not enter the castle. Instead, fly further across the lake to find another part of the castle.
|World 5-3 Warp|
After entering the first door, use Luigi to reach the vase at the top. There is also a potion located there. Enter the new door and then the vase to warp to World 7-1.
|World 6-3 Shortcut|
In World 6-3, climb the vine or go through the door to get to the next area. Then, instead of going right through the world, go left into the quicksand while holding Left. As soon as you see your character's head disappear. Start jumping to the left. Keep going until you reach a door. Go through the door. You should then be on a cloud. Keep jumping from cloud to cloud until you see the door, then enter it.
