There is a warp in Whomp's Fortress that makes going up the fortress a lot easier. Go
until you reach the area where a Thwomp is pounding the ground. There are several boxes
and a ? box there as well. Stand in the corner between the wire wall and the fortress
wall. The game will warp you to a ledge coming out of the fortress, next to a large pole.
You can also warp from the ledge to the area where the Whomp is.

Go to the first mission of Jolly Roger Bay. You must have Mario to do this. From the
starting point, there should be some of those orange brick blocks near you. Destroy them,
and get the Shell that's inside. Take the shell out onto the water, and look at your
map.Surf over to the ship (The dark circle with the star over it), and when you get there,
try to jump off of your shell. (I think you jump and press R in the air.) You should land
back on the water and then fall under the surface. Swim down and let the eel come out of
the door. Then, go inside the boat. You will be underwater and a Treasure chest will be
there. DO NOT TOUCH THE TREASURE CHEST YET! First, swim up to the other end of the room
and get some air. Then, swim back to the treasure chest, but turn twoards the star. Now,
swim at the treasure chest, and swim as fast as you can twoards the star. Hopefully you
will land on a high ledge. Now, you can either jump to the top ledge, (hard) or crawl up
the hill. (Easy but slow. If you hit a high ledge, it makes this a lot easier and
quicker.) Now, open the box, and get the star inside.

You know those invisible red ? blocks? Well, when you have 14 or more stars, go stand in
the sun and look up (X). You will be taken to the Castles in the Sky area. Fly down and
hit the big red ? switch. Red blocks will be activated. To leave the area, you can either
collect all eight red coins or dive down into the sky.

In level 15 Rainbow Ride, ride the carpet all the way up to the Floating Mansion. Walk out
of it and stand in the grey area in between the Mansion Entance and the Wooden Platform.
you will be teleported to the top of the Red Coin Maze or vice versa. Be careful, on top
of the Red Coin Maze, there is a 1-Up Mushroom but you can also be blown off by the wind.

This trick allows you to make new coins appear using Yoshi. You can use the extra coins to
get to one hundred coins faster, or to increase your coin record on a particular level.
This trick is fairly simple to do. Start off by choosing Yoshi and entering any level. Go
up to an enemy, and swallow it. When you swallow the enemy, press R to turn it into an
egg. Then, find another enemy, preferably one that is near several other enemies. Aim so
that your egg will not directly hit the enemy, but will ricochet off of the enemy. Shoot
the egg. The egg will hit the enemy and then bounce of. Since the game thinks that the egg
exploded, it will place the enemy coins at the place where the egg hit the enemy. It will
also give you the coins for the enemy if you defeated it. Since the egg was not destroyed,
however, it will continue to go and hit another enemy. When it hits the other enemy you
will receive coins for defeating the enemy, and you will receive the enemy coins from the
egg again! If the egg bounces off several enemies before it breaks, you will receive coins
multiple times for the enemy that was in the egg. The more times the egg bounces off
enemies, the more coins you get. This is especially useful when you swallow enemies that
give you blue coins, since you can get many blue coins by using this trick. This trick is
difficult to pull off on regular enemies, but it is worth it. This trick is easiest to use
if you shoot the egg at a Bob-omb since they are small and usually do not break the egg.

In Tall, Tall, Mountain, there is a warp that makes it easy to get to the cannon. In the
area with all of the mushrooms, you will see two tiny mushrooms that are next to each
other. Jump to the second tiny mushroom, and you will warp to a hidden area below the
mountain. From there you can head to the cannon. You can also warp from the hidden area to
the mushroom if you decide not to use the cannon.

Whenever you see the ice water at course 10, Snowman's Land, don't stay in for too long.
Your health decreases instead of increasing.

Lose your cap as Mario, then hit a ? Block containing a feather. Because you have no cap,
a short-fused Bob-Omb drops out instead. Run away!

There is a warp in Bob-omb Battlefield that lets you get from one side of the level to
another quickly. After going up the first slanted bridge, go right and stand in the flower
bed. The game will warp you to another flower bed, near the mountain. You can also warp
from the flower bed next to the mountain to the flower bed next to the slanted bridge.

This is for the Cool Cool Mountain slide inside the house. When you come up to the first
tunnel, look for a line of 5 coins going into the wall. Follow the coins into the wall and
you will take a secret path with 3 1-Ups in it. Note: You can't use this to get the star
in the Penguin Race.
