3-8 (42? coins)
4-2 (22 coins)
5-5 (28 coins)
6-7 (78 coins)
7-2 (42? coins)

These secret items will allow you to warp. Here are their locations.

Level 1-3
Find the white block near the end and crouch on to of it for 5 seconds. Then proceed to the goal, and go behind it. You will find a Mushroom house with a Whistle.

Level 1 Fortress
Fly over the top of the level when you find the first door with your raccoon powers, and find a hidden door at the far right on the ceiling. It leads to a warp whistle

Level 2 Hammer Brother
Get the Hammer from one of the Hammer Brothers here and use it to destroy the rock at the upper right corner of the Level 2 Map. Then engage the hammer brother on the other side. You should get a chest with a Warp Whistle.

You could just use the warp whistle at level 7...

If you want to go straight to level 8, you must use a Warp Whistle to proceed to the Warp Zone, then use another warp whistle IN THE WARP ZONE. You will be transported to the level 8 pipe at the bottom of the screen.

To get the N-Spade card game to appear on the World Map. You must do gain 80,000 points as one player, and successfully beat the stage that you broke the 80,000 points with.

Get through an airship and defeat the boss as a frog, Hammer Mario, or Tannooki, and you'll receive a letter from the King that reads a little differently.

To turn a wandering hammer brother (the ones that walk about on the world map) into a white ship full of coins, collect a number of coins that is a multiple of 11. Make the tens digit in your score match the multiple of 11. Stop the timer at the end of the stage that you are playing in on an even number.

One combination would be: 11 coins, 9,310 as your score, and the timer at 104. This only works in worlds 1, 3, 5, and 6.

To ''hide'' behind scenery, simply hold down for a couple seconds while standing on a white block. Then your player can ''hide'' behind scenery for about thirty seconds.

Get to World 1-2 as Raccoon Mario, with the tail. Climb the hill at the beginning and jump over the horizontal pipe. Stand there for a bit and a whole bunch of Goombas will start walking out of the pipe. Wait for 2-3 of them to come out of the pipe, then jump ontop of one and HOLD A to fly high into the air. Now that you are in the air, use your tail to slowly glide down from the air. On you landing, be sure to land on a second Goomba. Repeat this process for as long as you can. Eventually, the points you get for hitting each Goomba will turn into extra lives. This can be done for as long as you desire to do so.

This can also be done in 2-Fortress, and 7-5, but it is most notably done in 1-2.

Only the top part of Boswer can hurt you. So, it is possible to run through Bowser as small Mario and not get hurt. Or, you could have big Mario duck while Bowser tries to stomp on him. He'll remain unharmed.

In Bowsers castle at the end of the game, it is possible to make it so he DOES NOT SPIT FIRE AT YOU. This trick is easy and only requires getting to world 8 with a P-wing. First off, use your P-wing on the map before entering the Final Castle. YOU MUST GET TO BOWSER INTACT. If you get to the Bowser fight room and the Bricks that he smashes through are not flush with the rest of the floor, then you are in the wrong room. Now, when you reach Bowsers room, FLY straight up and to the left. You will be able to walk on a wall above the screen. Drop down on the other side. You will be in another room to Fight Bowser in. When you drop, you will be on a door that opens to the princess. Ignore this room and DO NOT GO TOO FAR TO THE LEFT. If you do, you will have to fight Bowser and he will still have his Fire Balls. Fly back over the wall to the first room you were in and start the Bowser fight. He will still throw his head back and make the sound of spitting fire, but nothing will come out. ;)

Complete the game and watch the ending. Now start a new game. You got 28 P-Wings!
