Getting Mario
To rescue Mario, you need at least 8 Stars. Go into the castle version of the rec room, where Toad is worried about losing Peach's rec room keys. Open the 8 Star door. Go forward, jump across the platforms, climb the pole, and reach the top of the huge tree. Jump down the hole on top of it. To defeat the following Boss, Goomboss as Yoshi, just run behind him, swallow a minion, and throw it back at him. After each hit, he will grow and redden. After three hits, he will be defeated and you will get the key to Mario's room. Then, just unlock the door and go inside.

Mini-game requirements
Mario

Getting Luigi
Go to the courtyard with the fountain and the ghosts. Look for one ghost that larger than the others. Use Mario to stomp him. Enter the small object that it drops to reach Boo's mansion. Get the first Star. On the second one, go up to the second floor. Continue on to defeat Big Boo and get Luigi's key.

More mini-games
To unlock more mini-games in the rec room, catch a rabbit with the character you want more mini-games with. For example, catch a rabbit with Mario to get another Mario mini-game. Additionally, after you have been in Princess Toadstool's (Peach's) room with the big dresser and all the drawers, go outside in the front yard of the castle. You will need to be playing with Yoshi. You will see three rabbits grouped up together. If you go near them, they will run away very fast. Run after them and catch them with your tongue. The rabbit will plead to let it out. You will automatically spit it out. After it complains about you about almost swallowing it, it will give you a key to the drawers, which will unlock more mini games in the rec room for Yoshi. You will get three keys, because there are three rabbits.

Glowing rabbits
There are seven glowing rabbits that randomly replace each of the character's mini-game rabbits. Once you catch all seven, you will receive a key that unlocks the white door to the right of Wario's. You will receive a Star. The rabbits must be caught in order. The order is as follows:

Star bonus
Obtain all 150 stars and go outside the castle. Climb inside the cannon opening that is now located where the grating was near the Fish Pond. Aim to land onto the roof, where you will meet Princess Peach and get 100 lives.

Secret Star in Mirror Room
Once you have access to the second floor, visit the Mirror Room with Luigi. Grab a flower and walk into the mirror to pass through it. Go straight to the door in the background and it will open, bringing you to a completely white room with a star in it. To get back into the main area, grab another flower or go to the right to free Wario (if you already have not done so).

Secret Star
When you go up the stairs and have one Star, you can go through a door with a number one on it. When you go in, go through one of the pictures of Peach. One of them contains a level with a secret Star.

Getting Wario
Play as Luigi in the Mirror Room. Jump into Wario's painting and defeat the Giant Ice Bully to get Wario's key.

Secret in Peach's Castle
Enter the room where you can change into different characters (Before the room with the Toad and pastel colors). Jump into the glass window of Peach next to Yoshi's door (on the right). You will enter a Castle Secret. You can get three Stars here. Make it to the bottom of the slide to get the first. Make it to the end of the slide in under twenty seconds for the second. Get every coin in the level (including blue ones) for the third.

Secret in Ship
Got to the room on the first floor with the entrance to the level with the sunken ship picture. There all small square holes on the walls. Jump in the one on the left to get a 1-Up. Jump into the one on the right to enter the Castle Secret. To earn a Star you must swim through the tank and get all eight red coins. To get air, you must grab the other coins -- their is no way to get out of the water.

Mushroom 1-Ups
When you get a power-up mushroom (that makes your character bigger), start plowing down enemies, signs, etc. A number will appear after every object you hit. After the number "8" appears, you will earn a 1-Up for each enemy hit.

Easy lives
Play a level with a 1-Up, such as Bomb-Omb Battlefield. Collect the 1-Up mushrooms, leave the level, then go back in and repeat. You can do this as many times as desired.

Easily refill health
When Mario's energy is low, find water, swim underwater, then get some air. Additionally, to regain health, just collect coins. You can also try to destroy an enemy to see if an item appears.

Mario loses hat
Go to the level where you can see the snow level in the mirror. Climb the mountain when you get to the head where the penguin is found. The snow head guy will blow you off. If you are Mario, your hat will fall off and you can leave the level without it.

Drain water under bridge and Star
After getting Wario, go to the basement type place. Go though one of the doors with no star on it. You will reach a sign that says something about the two pillars in front of you. Ground Pound both of them, and the water will sink. After that, go outside close to under the bridge. There will be a one of those black brink type things -- make sure you have Wario. Then, ground pound it. You must collect all the red coins to get the Star in that secret spot.

Shortcut to King Bomb-Omb
When you get past the gate, you will see hill with a red coin. The only way to get up that hill is to hold Y (dash). Every once in a while, change the camera angle. Another way is by transportation. Go along the normal path of the level and you will eventually see a hole in the wall. Stand in that hole and do not press anything. You will be instantly warped to the second top layer of the mountain. The last way are the cannons. Just blast yourself up there, but be careful. Mario flies slightly below the target. Make sure you raise the cannon a little above your target. This will save some time.

Stop the clock level
To stop the clock level on the third floor of the castle, jump in at exactly 12 o'clock. Additionally, go in at 3, 6, or 9 o'clock to make it slow, medium, or fast; respectively.

Flood in Wet Dry World
After getting the key from the second Bowser, go upstairs and walk through the door that leads to the room with all the pictures. Stop when you get through it and look around. In front of you is a picture of a spider. It is Wet Dry World. To flood it, jump very high into the picture. If you time the triple jump extremely well, you will flood Wet Dry World.

No water in Wet Dry World
This trick is very similar to the "Flood in Wet Dry World" hint. The only difference is, instead of jumping high into the picture, jump very low into it. You should try to jump directly into the bottom of the picture.

Mysterious mountainside in Tall, Tall Mountain
Go to the top of the mountain and get the Wario hat. Jump down until you see a group of coins on the side of the mountain. Jump through the wall to enter a secret slide game, in which the reward is a Star.

Fun with Goomboss
Go back to the place behind the Princess's Drawers to the door with an 8 on it with Mario. Enter the fight with Goomboss, and eventually he will throw a mushroom. Touch the mushroom and Mario will grow tall, just like in the classic Mario games.

Defeating the Goomboss
As Yoshi, run around the arena as fast as possible and try to get behind the Goomboss. Swallow a Goomba that follows him. Wait for it to become an egg and throw it at him. Repeat this two more times.

Defeating King Boo
Get to King Boo by going through the Luigi picture in the Boo House. You can tell where he is when he disappears in the mirror by looking for his shadow on the floor.

Classic Mario game reference
When the game starts, go to the rec room. You will hear the level selection screen music from Super Mario Bros. 3.

Drawing
When the game starts and Mario's head appears, touch him. The screen will draw Mario. To draw your own picture, touch the pencil on the bottom-right. You have a paint meter at the bottom. This determines how much more you can draw before it automatically makes it into an object. Additionally, if you cannot figure out what to draw, press R or L before you start drawing. A faded image of Mario will appear. The same happens for Yoshi if he was on the screen that was touched at the start.

Drawing controls
Thicker lines: To make your picture's lines thicker, press Up.

Mario's basic techniques
Note: These basic techniques can be performed in standard mode:

Character power-ups
Luigi

Rabbit for Luigi
Go to the area with all the ghosts and where the door is located. Jump, then grab the ledge. Climb it, then jump up again. There should be a green rabbit up there.

Secret Star in Castle
Stand on the sun platform in the middle of the main room in the castle with Mario. Gaze up at the sun above the final Boss door. You must perform this trick with Mario because he is the only person that can fly. Inside, you must collect eight red coins and a Star will appear on the center platform. Note: You can only receive this star after you reach a certain point in the game. You will know you have reached this point when the sun shines through onto the platform.

Secret area
When you have a good amount of Stars, go to the part of Peach's castle, where there is a flame-like painting on the wall. Then, go down the left hallway until you reach a dead end. Jump through the wall at the dead end. If done correctly on the correct wall, you will access a secret level.

Easy Stars
Some very easy Stars appear when you talk to some Toads in different rooms around the castle.

Stop The Clock level
To stop the clock level on the third floor of the castle, jump in at exactly 12 o'clock. Additionally, go in at 3, 6, or 9 o'clock to make it slow, medium, or fast; respectively.

Shifting Sand Land
To get to Shifting Sand Land you must enter through a wall hidden down near the Lethal Lava Land level.

Easy lives in Hazy Maze
Go to the part with the poisonous gas maze. Get to the section aboveground that has two gopher holes on it. Near that area should be a breakable box with a Super Mushroom inside. Get the Super Mushroom and run to the two gopher holes. Walk over the holes, killing the alternating gophers back and forth until the mushroom wears off. It is possible to get 40 lives this way. Note: This works best with Wario.

Defeating Lethal Bombs
To kill the Lethal Bombs, either jump at them or punch/kick them ahead of time.

Luigi drawing
At the main menu, when Mario's face is looking around, tap his face the first time he turns and faces all the way to the right. It will draw Luigi's face instead of Mario's.

Psyche Out! mini-game
The mini-game tests your psychic abilities. There is a trick to beating this game. If you look carefully at the waving card, you should see a faint outline of the image that is on the back of the card. If you can not see the image immediately, wait a few seconds and you should get a glimpse. This will happen more frequently on the harder levels.

Secret Star in Hazy Mazy Cave
Go to the Hazy Mazy Cave course. Go to the left and follow the path to the underground lake. Jump on the dinosaur and grab the Wario Cap. Point in the direction of the metal doors and he will take you there. When you get inside, jump in the metal pool. Collect eight Red Coins to get a Star. Note: Use Wario's Power Flower to help you get the underwater coins.

Avoid death from high falls
If you fall from a very high location, wait until you are just above the ground and press R. You will do a butt slam and will not get hurt.

Snowmans Land
Go in the mirror room and find the snowman painting in the mirror. You will see that it is only in the reflection. Jump in the wall that the snowman painting should be on and you will be in Snowmans Land.

Extra life on Princess' Secret Slide
If you get the first 1-Up mushroom, there is a second 1-Up behind the Star Box's platform.

Star in Tick Tock-Clock
As you enter the room with the Tick-Tock-Clock level, there is a Toad standing against the right brick column. Talk to him as Mario and he will give you a Star.

Slide in Tall, Tall Mountain
Go to the bridge at the top of the mountain. Go underneath. There should be a cloud that is trying to blow you down. Follow the coins. At the end of the slide, you should end up in a cage. There should be a Star here.

Defeating Koopa the Quick
After you challenge Koopa the Quick, run up the bridge as usual. However, when you get past the bridge, run over to the flower patch near the red block. If you go to around the middle of it, you should teleport directly in front of the mountain. From there, instead of going to where the rolling bowling balls are found, go up the steep hill. This may not seem it is faster, but it is. Continue running up the mountain until you reach the first hole where the bowling balls are coming from. Jump into the hole. You should be teleported to the second bowling ball hole. Then, run up to the flag. If done correctly, this should be an unbeatable strategy for defeating Koopa the Quick.

Walk while underwater
Play as Yoshi and find Wario's hat. Then, get his power-up so that you are metal. Before it runs out, get hit by an enemy while near a slope like the sunken ship. For example, jump off the bow to the wall and get hit by the eel. Yoshi will lose his cap, but not swim. You can walk around on the bottom slowly, but can still drown.

Mario's floating power in Bob-Omb Battlefield
Select Mario and collect either Wario's or Luigi's cap to turn into that character. Then, lure an enemy to the red power-up box. Break the box while wearing Wario or Luigi's cap and a Power Flower will appear instead of the Feather. Then. get hit by an enemy to turn back into Mario and collect the flower. Mario will float instead of getting the Wing-Cap. This trick can also be done in other levels that will give Power Flowers to Wario or Luigi (but not to Mario), as long as you can get hit to lose the other character's cap and collect the Power Flower as Mario before it disappears.

Alternate Mario or Yoshi introduction drawings
At the first time on the start up screen, you will see Mario:

Luigi's 5 Card Draw Poker mini-game
To get a very high score, exit the game and come back to it if you get a bad hand. Doing so will not effect your coins or winning streak.

Secret Underwater level
When you enter the castle, go to your right. There will be a door with a "3" on it. Enter it. There will be a painting with bubbles inside. Go to your right. There will be a raised box up in the wall. Jump inside and it will take you to an underwater level. Collect all the red coins and a Star will appear in the center, on the bottom.

1-Up Mushrooms
When you get a power-up mushroom (that makes your character bigger), start plowing down enemies, signs, etc. A number will appear after every object you hit. After the number "8" appears, you will earn a 1-Up for each enemy hit. Additionally, when you enter the castle, go to your right. There will be a door with a "3" on it. Enter it. There will be a painting with bubbles inside. Go to your left. There will be a raised box up in the wall. Jump inside and there should be a 1-Up Mushroom.

Star in Whomp's Fortress
Use the following steps to get the sixth Star in course 2. Go into the cannon by the water. Aim the cannon by the far, thin wall. Hit the corner and the wall will break. Soon after that, a Star appears.

Mario, Luigi, or Mario acting like Yoshi
While playing as Yoshi, get anyone's cap. While flashing blue, use Yoshi's tongue power. You will see Mario, Luigi, or Wario bending over like Yoshi when he uses his tongue attack.
