While Mario, Luigi, or Wario, lose a cap in any of the stages that you can lose a cap... and leave the level... While you have no cap, go to any other level, get any star and when you return to the castle, go back to the main hall and toad is there wearing your cap!!! He will say that he found it outside the castle front. This is also good in case you lost your cap somewhere but you don't know where you left it. Check it out, it's pretty neat.

After getting all 150 stars, return to Cool, Cool Mountain and you can race a fatter version of the penguin.

Start as Yoshi, then go somewhere with the small square crates (like in the start of Hazy Maze Cave), lick it up, then swallow, you egg should be a square egg now, talk about easter egg.

It is possible to have certain characters gone in the final ending sequence of the game. In order to eliminate characters from the final ending sequence, you must complete a simple task. You must not unlock them in the game. If you do not unlock a character in the game, he will be missing from the final ending sequence. The entire sequence will go by and you will never see the character. Also, on the cake at the end, the locked character will be missing and the other characters will be in different positions.

Instead of pounding the wooden posts found in some levels circle around them three times to reveal five coins.

If you are low on health, just find a body of water and jump in. Stay at the surface and your health meter will refill.

Jump in the clock on 3 and it will be slow. Jump in the clock on 6 and it will be medium speed. Jump in on 9, and it will be fast.

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.

In Cool, Cool Mountain, there's a transport from the 2 broken bridges, 1 near the starting point, and 1 near the big penguin outside(next to a sign and red coin). Walk to the edge of the broken bridge, stop for a second, and you will be teleported to the other bridge.

In Lethal Lava Land, at the beginning of the level, turn left and walk across the platform, jump across to the island in the lava. On a certain place on the island, if you just stand there, you will be transported underneath the giant eyeball near the center of the level. (do not try with luigi while invisible because you will keep bouncing on the lava and probably die, since you go through the platform)

In order to stop the gears and platforms in the Tick Tock Clock, simply jump into the clock when the minute hand is on the 12.

After collecting all 150 power stars, beat Bowser in his final stage, he will say something different than normal, I won't spoil it

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.

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.

There is a warp in Bob-omb Battlefield that allows you to go up the mountain quickly. Begin by heading up the mountain until you come to the first indentation in the mountain that metal balls come out of. Go into the indentation, and stand there. The game will warp you to another indentation higher up in the mountain.

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.

In Shifting Sand Land, head over to the tree that is next to the oasis. Stand under the tree, and the game will warp you to a metal platform in the quicksand area. The cannon is there, as well as a black brick block. You can also warp from the metal platform to the tree.

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.

You can destroy those annoying Tox Boxes in Shifting Sand Land by Being/Turning into Wario, then wait for the tox box to come to you and right when you get in the part that is hollow, punch in any direction and you will send it flying and you will have a clear walkway.

For this warp, head over to fenced in area where three Goombas are huddled around a campfire. Stay outside of the fenced in area, and stand under the tree closest to the fence. Your character will warp to another tree, right next to the freezing pond. You can also warp from the tree in the freezing pond to the tree next to the campfire.

For this warp, the water level needs to be as low as it can get. Walk around the base of the level until you find the brick structure that is made of several steps. Stand at the base of the structure, in the corner between the highest and lowest steps. The game will warp you to the top of the structure that holds the entrance to the cannon. You can also warp from the cannon to the other structure.

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.

On level 6, Hazy Maze Cave, go into the hazy maze as any character except yoshi (preferably wario since he can become metal) and navigate until you find a red brick block, inside will be a mushroom. Grab that mushroom and go around the corner.

There will be 2 moles, (i forgot their real names), keep running in circles over the holes in the ground that they pop out of and you will repeatedly kill them. After killing 10 you will start gaining lives, continue this until the mushroom runs out. You should have 40-60 extra lives now.

As soon as you start seeing glowing rabbits (they randomly appear in place of the character's other rabbits) go change to Yoshi. Yoshi always has three rabbits right at the end of the bridge of the castle. Go outside and check and see if any of them are shining. If not, walk back in and walk back out and check again. Eventually, one (or more) of them will be glowing. You can keep doing this until you get all eight rabbits.

First go into Whomps Fortress as Mario and choose 2nd-7th star. Then, go to the teleport near between the wired fence and wall, but don't use it. While there break open the box with the Red Mushroom in it. Get the Red Mushroom you should become large, then use the teleport. After you re-teleport, jump over the small fence and jump on the ledge with the castle on it, and pull yourself up. Go to your left, and touch the thinner side of the board, it should fall and you still should be large. Now just keep on walking/touching it and your life should go up FAST.

Use this trick to get the star "Red-Hot Log Rolling" easily. Start as Wario. Instead of going forward, turn back. Rotate the camera, and you will see a small island with a red "?" block. Do a long-jump to get to the island, and take the flower in the block. Wario will be turned into metal, and can now walk on the Lava. (Be careful, the lava works like the quicksand in "Shifting Sands Land")

Go to the area with the Pirrahna Plants and hit the switch. Run across the bricks and onto the island. Now get the coin and wait in that spot. You will be teleported to the pipe near the Pirrahna Plants again.

Enter Wet-Dry world, and set the water level so just the tip of the large gray spiral ramp is in the water. Swim around to the underside of the ramp, and swim up towards the ramp while jumping. If done correctly, you should fall down to the bottom of the level, and be able to move like normal under water.

As Wario, go outside to the Boo-infested courtyard. Position yourself so that a Boo is between you and the rabbit. Run and dive for the rabbit. As you do, the Boo will solidify and knock you away while you catch the rabbit. Then walk back to the rabbit. It will not move, but it is now untouchable, like a Boo when it transparent. This can also get funny screenshots if Wario stands inside the rabbit, which makes it look like Wario has rabbit ears.

When Bowser's Submarine is still in the docking area, head over to one of the back propellers. It is just slightly above the water. While underwater, jump up under it then quickly Ground Pound. Your character will fall fast through the water and land at the bottom. You can now walk underwater, so you can easily grab several of the Stars that lie there. This only works while Bowser's Submarine is there.

In Cool,Cool Mountain, go down into the cottage and go down the slide. Exit the cottage and kill the three goomba and grab their coins. After you get the coins, go to the warp and repeat the steps above. The coin counter only goes to 255 so that will be you're high score. It takes time but eventually you will get there.

In multiplayer mode, get the Wario hat and grab a player by standing next to them and try to punch them. Throw them, and grab the star that falls out of them, (If they have a star). Pick the enemy up again and ground pound with them in your hands. They will drop another star, even if they have none in their count. Rinse and repeat for as long as you like.

Ordinarily, you're supposed to have 80 stars to finish the game, but with this glitch, you can finish it with 50. Go into the room on the third floor which contains the levels "Tick Tock Clock" and "Rainbow Ride". Once you enter this room (which requires 50 stars to enter), run to your right, and climb onto the second step. Angle your character so that they're about halfway between the corner and the edge (and have them facing the corner). When they're in this position, charge up a run, start running, slide kick, and hold right on the D-pad. If all goes well, you'll slide into the corner, and get shot into the sky. From here, you can navigate your way to the top of the endless stairs while they are still endless, and enter "Bowser in the Sky", and hence finish the game, with only 50 stars. This glitch can also be used to access "Bowser in the Sky" as characters other than Mario.
