On world 4-1, get the princess. Go up the vine, but go 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.
Finding Fry Guy
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. Go through the second door to fight Fry Guy.
Maximize your coins
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. 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).
In world 3-1, take 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 there is a continuous stream of coins. Enter this door, and grab as many coins as possible. Go out the door you came in, then return, and repeat once.
Each time the spinners start in the bonus round, the second symbol in the first slot is always a cherry. Do it correctly, and you can guarantee yourself an average at least one extra life per coin.
On world 5-3 select Luigi. Climb up the ladder and you will see a ledge. with some grass and a cup like thing. Squat down and when Luigi starts blinking, jump up onto the ledge. Pick up the potion and set it down somewhere. Enter the door and go into the white cup. You will be warped to world 7.
This code is to explain more to one of the cheats. It is in world 3-1, there is a massive waterfall that you must fall down. Do not worry, there is a long fall, and you will not die- just stay at the center at all times. You will reach a piece of land with a door: enter. Before you start ripping through the plants, you must know there is a potion amongst the plants. The potion is 10 plants from the left, so 5 remain on the right after you take it out. Set the potion in the middle to get all plants. Enter the door and start picking up plants like crazy, because each is token for the slot machine.
Warp I-(World 1-3 to 4-1)
Carry a Potionto the right side of the tower. Throw it into the jar. Enter Subspace and warp by going down the jar.
Warp II-(World 3-1 to 5-1)
Go down the waterfall carefully. Enter the door. There will be lots of plants when u enter. Pick up the tenth one on the left. Enter Subspace and warp by going down the jar.
The best characters are Luigi and Princess Peach. Luigi has the best jumping abilities. Princess Peach can stay in the air for a long time.
How to defeat last boss
