 Move map
Press A on the map screen to zoom in. Then, use the C-stick to scroll around the floor that you are on.

 Treasure rooms
Go to the southwest corner of the on the mansion's first floor. Vacuum the butler that carries a candle. Look at the room with the Game Boy Horror to find a mouse hole. Press A to examine the mouse hole and enter a hidden treasure room.

Take the elevator in the toy chamber up to get on the chimney in the mansion's roof. Fall off to land in a hidden treasure room.

After you defeat the three clock soldiers, the Shyguys, and the Ice Element ghost, pick up the key that is in the top of the left ladder tower. Do not go back downstairs after you get i. Instead, go to the top right ladder tower with the hole at the top. Walk the plank that is above it and drop down. You will learn that it is really a chimney in the room where the door is boarded up. This is the only way to get into this location, which is a treasure room. The first treasure chest you open will contain a ghost. There are not that many, and you do not need a special element to defeat them. Defeat the ghost and open all the treasure chests. You will also get a key to another room. Exit through the mirror transport.

 Finding Boos
You can capture the fifty Boos that were let go at the start of the game to get a large diamond. To do this, use the Game Boy Horror in Boo sensor mode. Boos tend to hide in rooms with lights. Search all locations within such rooms. A blue Boo sensor light indicates that there is no Boo present. A yellow Boo sensor light indicates that a Boo, Booball, or Bomb is near. A red Boo sensor light indicates you are directly next to a Boo, Booball, or Bomb. Get the Boo sensor to be red, then turn on the vacuum or press A to examine the target object. If Booball appears, leave it alone to send it at a wall. Run away if a bomb

You can only find Boos in rooms that you have lit up. This is because the Boos draw their power from the darkness. After you find a Boo (in a lit room), it may escape to an unlit room. If a Boo escapes into a dark room, it will be much more difficult to capture because its HP will drop much more slowly. This is because the Boos are stronger when they are in the dark.

 Capturing Boos
To capture a Boo easier, all you need is an Ice element. When you use an Ice element on a Boo, it will momentarily hesitate to move. This gives you a chance to use your Poltergust 3000 on them.

 Defeating Boolousus
When you get a chance, try to locate one of the frozen unicorns at one of the end of the balcony. While he's chasing you, just run circles around the unicorn. He will eventually run into the spike and pop on his own. Be careful -- once the Boos are separated, you have to watch your back. They will run up behind you if you are not looking at them.

 Defeating Chauncey
After you defeat the Neville and Lydia, you get to Chauncey (the baby). You have to defeat him two times. The first time, you have to pick up the ball with the Poultergust 3000, aim, and press L to fire. Hit her and she will blab about her owee. You become small and she will be very big. She will throw rocking horses and balls. When all the balls are done bouncing, one will be stationary. Pick it up, aim, and shoot it at her.

 Defeating Lydia
Use the following trick to capture Lydia. After you defeat the Neville, he will give you a key. Go to the room at the end of the hall. Enter and a girl ghost will be there, setting her hair. Go to the window go in front of the curtain to the right. Stand facing to the right then vacuum with the Poultergust 3000. It will move to the right and the ghost will walk to the window saying "Oh what a draft". Use this chance to vacuum her up.

 Defeating Mr. Luggs
Use our Fire element to light the two candles. Suck up his food with the vacuum. Ghosts will appear and serve him -- vacuum them up. When the food is gone, he will shoot fireballs at you. Dodge them and when he starts panting, vacuum him up.

 Defeating Neville
To capture Neville, go over to the bookcase and vacuum with the Poultergust 3000. Books will fly out and he will go over to fix them. Use this opportunity to flash the light and vacuum him in. You still have to vacuum in 100 heart power. If you fail the first time, he will still not regain health. Repeat this a few times to vacuum him in.

 Finding Henry And Orville
After the twins tell you to hide and you reenter, vacuum the boxes. If the box shakes, open it.

 King Boo
When you finally make it to King Boo, you will have to walk very close to start him talking. Instead, go directly to the right. You will see two vase-like objects with purple flames coming out of them. Hit them (to check inside) to find a gold bat in one and a lot of coins in the other.

 Vacuuming ghosts and Boos
If you can barely catch a Ghost while vacuuming, or just want a faster way to do so, quickly rotate the C-stick. This is easier for those who do not have too great of a time holding the C-stick in the opposite direction of the Ghost, as each rotation will land at least one heart off the ghosts.

When you have one of those Ghosts in your reach, you have to go through the difficulty of rotating the C-stick, which can be troublesome. To avoid this, when you find and consume those scattering spirits, try staying in a corner of the room. , and stay in that corner. See, that gives them only so much room to escape. When you are in a corner, it minimizes their rotation to only 90 degrees, eliminating 75% of the struggle.

When vacuuming ghosts, instead of just holding the Analog-sticks in the opposite direction of the ghost(s), repeatedly tap them in the opposite direction. The ghost's hearts will drop a lot faster.

Use the Analog-stick and C-stick to aim at a Boo. Once its HP begins to drop, stop using the C-stick and use only the Analog-stick to follow the Boo around the room. Luigi will automatically change direction according to the Boo's movement. The closer you are to the Boo, the faster its HP will drop. However, if you touch the Boo, you will get hurt and the Boo will escape the vacuum. If the Boo escapes through a wall, check your map to see which room it has escaped to. Go to that room as quickly as possible.

 Throwing Element balls
First, get an Element. Start to shoot the Element, and when you see the Element to start to flow out of your Poltergust 3000, press L again. An Element ball should shoot out of it.

To see an Element ball approach you, go to the first floor corridor where the door on the left is the Dining Room and the door on the right is the Ballroom. Have Luigi face you and fire an Element ball. This works with all three balls.

 Avoiding trapped doors
To avoid losing coins and life from trap doors, just vacuum towards the door you want to enter. If it rattles and shakes around, it is safe to enter. If it does not move or rattle, it is a trap.

To avoid being hit by the trapped doors, note that Luigi will look at them as he walks past. Luigis will also do this if he is near jars or anything else with money or a ghost in them.

To avoid being smashed by trapped doors, look to see if there is a doormat at the base of the door. If there is a mat, it is safe to open.

 Get rid of fake doors
Use the Flamethrower element on the annoying fake doors and they will melt and disappear. Note They will return after you enter another door.

 Warp mirrors
Any mirror in the mansion (except for the large one that reflects the invisible ghosts) can be used to warp back to the entrance hall. Set the Game Boy Horror to first person mode and press A to examine the mirror.

 Warp from the well to the main entrance
Go to the well where you can see Mario In the picture. Look directly ahead with your Gameboy Horror, and press the A button. You will be teleported to the main entrance (the mansion door).

 Secret altar
You can view the secret altar by going down in the bottom of the well and looking into it. Access all the rooms in the house to finally obtain the key to the secret altar. Once you have the key, the door with the thorns in the basement level will open. You will see the Boo King looking at the Mario painting. Before you get too close, vacuum up the candles to your right, in front of the mirror just as you walk in. A lot of coins will appear from the candle while you vacuum them out. Some bills will also appear. The candle next to it has a bar of gold that you can vacuum out. You can then go over to the King Boo and battle him on the roof top. Note He will take the appearance of Bowser.

 Treadmill Key
In the weight room is a treadmill. Run on it to get the key to the hall door just to the left of the room. With the hall door unlocked, you will not have to run around the back side of the house to get to the stairs that lead to the second floor.

 Treasures from plants
Go to the outside section and find the seen to the right of the dog house, towards the graveyard. It can be found under Toad's balcony. Get the Water Element ability and water the seed. A plant will appear. Press A on the Game Boy Horror while examining the dog house to enter it.. Defeat the Boss that is inside, then water the plant again. Continue playing the game, then water the plant again after defeating the next Boss. The plant will flower and give you a diamond. If you do not water the plant after each Boss battle, it will die.

On Area 2, after you get the Water Elemental Medal and before you defeat Bogmire, go past the kitchen and go through the next door that has caught on fire. After you get the ghostly dog Spooky, go to the green thing with white polka-dots in the sand. Get a Water Elemental Ghost into your Poltergust 3000. Water that colorful thing. On Area 3, the plant will be larger. Water it again. On Area 4, the plant will be a big yellow thing. Water that again, and many coins and a golden diamond worth 20,000,000 g will appear.

When you get the Water element, water all the plants to find hidden treasures growing in them.

 Change vacuum power
There are three different medals you can collect to change the powers of the Poltergust 3000 vacuum cleaner. They are the Fire, Ice, and Water medals. When you collect the Fire Medal, you can suck up ghosts that have a ring of fire around the health hearts. Also, you can press L to spray fire from your vacuum to light candles and hit ghosts with a ice health meter. When you collect the Water Medal, you can extinguish flames that are too powerful for your vacuum to put out. Also, you can press L to spray water.

 Big heart locations

First floor graveyard When you interact with the leftmost gravestone, you will collect a big heart.

Second floor nursery The design of the heart-shaped dresser is a clue. Open the drawer to find a 50-point heart.

Third floor safari room Your first destination on the third floor is a difficult room. Its big heart is in a chest on a corner table.

Basement cellar The shelves in the center of the cellar hold a big heart. Pull it out with your vacuum.

 Extra hearts and money
Use your vacuum to clean all lamps, chandeliers, and vases. Most of them will contain either hearts (life) and money.

 Bigger hearts
Collect as much money and pearls as possible. The more you collect, the bigger the hearts will get. They can almost restore as much health as the large hearts do.

 Rubies
There are two large rubies in the game. One is the King Boo's Crown and the other is hidden in a plant on the Boolosus Balcony.

On Area 2, after you defeat Spooky, walk near the entrance of the dog house and press X. Press A while aiming at the door to go to the graveyard. To your right will be a rain drain. Walk to it and press A to get a ruby.

 Pokemon painting
On level two, when you catch five Boos go to the bathroom where you get key out of the toilet to find a painting of a Pokemon.

 The Munsters poster
Enter the twin's room. After you get the twins and the Boo inside their room, you can see a poster of the television show, "The Munsters" next to the bunk bed.

 Mario calls
When you press A, Luigi will call "Mario!". The more damage Luigi has taken, the more desperate his call for Mario will be.

 Hidden Boo picture
Although you cannot pull off the projection room screen, you can make it change. Give it a tug with the Poltergust 3000. If you are persistent, you will reveal a huge picture of a Boo.

There is another hidden Boo picture in the first floor bathroom. Vacuum at the poster with the word "Monster" on it. A picture of a Boo will appear.
