When u go to the hall on floor 1 take a right where the yellow and pink ghosts pop out.( I think that's right) you will see 2 lights on the wall. in between the lights press A and you will hear a sound that just doesn't sound right. (Luigi will say "hmm....") I'm not sure how too get through though.

How 2 beat Ghost Ghost and an Extra Bonus Hint!

Squash the Purple Ghost Ghost:
When you are a midget, use your Poltergust 3000 to form the black outlines into Footballs, then Fire them at the Purple Ghost
He will be mixed with Black and Purple and then you know what 2 do...

Bonus Ruby:
In the Dog's yard, stand in the middle of the garden and go to the bottom right hand corner, and use your GAMEBOY HORROR on the opening in the gutter. Now you get a very, very valuable Ruby! ;-)

Beating Melody

Melody is the ghost in the room with all the instruments.  To get to her, you need to go up to all the instruments and press A.  Once music notes are coming out of the instruments, she'll appear at the piano.  Melody will play a piece of music and ask you a question about it.  If you get it right then shine your light at her.  Then suck her up.

Beat Bogmire the Graveyard Ghost

Once you beat the fat ghost in the 2nd area, go into the kitchen on the left of his room. Suck up the pots, pans, and the blue ghost. You will get the water medal. Get water at the sink. Put out the fire on the burning door. Go through into the dog's yard. Once the skeleton says to make the dog quiet, suck him up. When the dog eats on his bone, suck him up. Go do a X+A on the weird sparkling light in his doghouse. You will go to the bone yard. Examine each grave until three skeletons pop up. Suck them all up. Go to the big blue grave. When you are in the round fenced off ring, suck up the clear Bogmire duplicates. You will have a shadow ball in the vacuum. This is similar to Chauncey. Shoot the ball at the real pink Bogmire. While he is struggling with the shadow, suck him up and avoid the duplicates.

Finding Uncle Grimmly

After you beat Area 3 and the power goes out, Professor E. Gadd will tell you to find a ghost in a room with a mirror. This is Grimmly and he in Area 1. About the 3rd room after starting the game. He is an easy ghost to catch. Just reflect the light off of the mirror to get his heart.

Get Elemental Medals

I'm not quite sure where you get the first element card, or the fire one.
To get the ice one, go through the door under the stairs in the foyer, then go right along the hallway in front of you. When you come to a hallway that intersects with the one you're on. Then, go through the first door to your left. Next, point and use your vacuum on the vase with the cubes of ice in it.
To get the water card, go in the backyard near the place you find Bogmire, the second boss ghost. Then, go to the place where the broken water pipe is. Finally, suck the bouncing bubble of water to get the third and last element card

50 point heart

When you go into the cellar, turn your Poltergust 3000 on the shelf and start sucking. A heart will pop out, and if you keep sucking a large heart will pop out.

Go to Main Entrance

Use a Game Boy Advance and look at the mirror in the rear of the gym.  Now on the Gameboy Advance press A while facing the mirror in the 1st person

Reset Game

Surprise the Secret Ghosts

Have you noticed that in some rooms there are ghosts that won't appear until you turn your back to them? Well in one room where you meet the first one, there is a shelf of books that
explain that you should wait a few seconds and pretend that you aren't doing anything and then turn around with the flashlight on and stun the ghost so that you can press the R button to suck up the 100 lifepoint ghoul!

Easiest way to catch the Big book reading Ghost

When you go to the room where the books fly at you go to the fireplace and start sucking the vacuum slowly walk backwards with the vacuum still on when you get to his tail like thing he will get sucked up and just hold on!

Get reading ghost

This made me very frustrated and i could never figure it out, but I finally figured it out a day or 2 ago.  There is this one room where there is this ghost and he is rocking in a rocking chair and reading a book (I think it's a book).  Anyway, leave your light off because it won't effect him.  Wait for him to yawn, then hit him with the flashlight!  I don't know why the designers made him vulnerable to the flashlight only when he is yawning, but just like the tootsie-pop commercial says "The world may never know...."

Unlimited health

Go to the room where the baby is. Make the baby wake up. When the baby try's to get you,run around him 20 times. Now when ever you get hurt it won't take away any hearts!

More Treasure

If you water all the plants in the mansion, most of them will give you treasure.

The Big, Bad Boo's Attacks

In the start of the game, Luigi releases 50 Boos. Yes, 50 Boos. To find the Boos, search lighted rooms with your Gameboy Horror in the corners. Yes, in lighted rooms. A green light means there's no Boo, yellow means you're close, and red means you're right on target! Press the A button to examine the area and hopefully find a Boo. Your reward, a large diamond!

Water the Diamond Plant

Below the balcony where Toad is there is a dog house and a plant where you can get one of the game's secrets. Once you have the water element go to the plant before you face the second boss and water it. Then, return and
water the plant after you beat the second boss. Then, once more, return to water it after you beat the third boss. Your reward is a large diamond (Note: if you fail to return and water it, then the plant will wither and die).

The Hidden Hearts and Money

If you are low on life energy, then get out your vacuum and suck in any lamps, chandeliers, or vases. Almost every one will have money or hearts in it, so do it often!

The 2 Treasure Rooms

There are 2 treasure rooms that are hidden pretty well. The first one can be found on the southwest corner of the mansion on the first floor. Use your Gameboy Horror in the room to find the mouse hole and then press the A button to go in to the treasure room. The second room is hidden so well that you can only access it from the rooftop. Fall down the chimney and you'll be in the last treasure room!

Extra Treasures

When you are sucking up a large ghost (Like the one sitting in the library), he will drop more treasures the longer you hold on to him. If you manage to suck up 90 of his HP continuously (note CONTINUOUSLY), he will drop EXTREMELY expensive treasure worth up to $10,000!

Ceiling Fan Secret

In the room with the ghost brushing her hair, there's a ceiling fan. Use your vacum on it. By now, you would of thought that there is nothing in it, but if you make it goes faster and faster, lots of treasure will come out.

Hidden Hole

There's a mouse hole on the east wall of the butler's room. When you select the hole with the Game Boy Horror and press the A button, you'll earn passage to the treasure-filled hidden room.

How to Catch SuperModel Ghost

In the Master Bed room there is a chair in the corner by the window, if you turn your back to it or look at it through the Gameboy horror, you will see a ghost that has a red dress on, if you go over to the window and pull the curtain back, she will go over and close the curtain back, and that is your time to suck her up.... OH yeah watch out for her mushroom things!

Mirror Trick

Go to any mirror, than use the Gameboy Horror and do a search directly at mirror. Should take you to Mansion Lobby. Good if you want to save and you dont want to travel through ghosts and stuff.

Beat The Big Baby

If you are trying to beat the baby Chauncey then, here is your answer. Ok first, go to the rocking horse in the back of the room. Then, start sucking the rocking horse so that it begins to rock back and forth. Chauncey will appear over top of the horse and ask if you want to play with him. As soon as he starts attacking, suck up the ball so that it gets stuck on the vacuum, then, keep sucking until you are aiming at Chauncey, finally, stop the sucking and switch to blowing, the ball should shoot at Chauncey, after that he will turn Luigi little. Avoid the rocking horses and when he starts throwing balls at you. When one hits the back of the crib and bounces to the front, suck it like you did when you were normal size and shoot it at him, if it hits him then aim your vacuum up a little bit and when his heart appears, start sucking him in, if you don't get him the first time try again, before he starts throwing the rocking horses, he will cry and start pounding the ground with his stomach, avoid this and repeat the above. When you have finished him off, you will be transported back to the lab.

How to beat Bowser

When bowser throws his spiked bombs at you wait for them to stop moving. Then pick them up with you vacuum. Then you have to wait till bowser lowers his head to breath fire or to breath you into his mouth and shoot it at his mouth the head will pop off and boo will pop out now turn on the vacuum and lower his health points while avoiding the ice blasts that comm from bowsers head. Repeat this process and you will beat bowser.

50 Boos = A Big Reward

This one is not really a challenge! Throughout the game, you will be catching Boos with your Boo radar. As you can see there are 50 in all (NOT including King Boo). All you have to do is catch all 50 and Professer E. Gadd will reward you with a golden diamond that is worth
$20,000. That is a lot of dough!

Beat the ghost in the dining hall

First you must have the fire that comes out of your gun. Then light all of the candles next to the ghost[there are 6 candles]. Once you have done that, you can scoop up the food he is eating. Now made ghosts will show up to give the fat ghost more food. While they are out capture them. Now you can scoop up all of the food there for making the big ghost mad. When he gets up and shoots fire at you, you need to go hide behind cabinet near the door on the right side of the screen. Then he will stop shooting fire at you and just sit there. Now you have to be real quick and go over to him and you can see his heart. Apparently now go scoop him up and you should capture him!

Money Ghost

First, start the game. Go get the key that ghost has at the begging. Then go upstairs and meet prof. E. Gadd. Then....blah...blah...blah. Now go back to the room get all the ghost.Go to the next room and get the ghost. Now in the last room with the clothes thingies, get all the ghost but don't get the one in the left clothes thingy.

She won't notice you unless you move the curtain in the background with the poltergust 3000. She will be disturbed by a draft giving you the chance to suck her in. 

Chauncey the bad baby.

After capturing Lydia, go into the nursery directed by the map. You won't be able to capture Chauncey the same way you did Neville and Lydia. First, make his little rocking horse rock really fast. Chauncy will cry and then wake up. He'll ask if you want to play with him. Avoid his flying teddy bears and suck up his ball. hit him with it. Chauncey will get mad and make you really small. So small, his crib is a battlefeiled. He'll then start throwing rocking horses at you. Run to evade them. then he'll throw big balls at you. All but one disapears. Suck it up then fire the ball at him while he does his crazy dance. If you hit him, you'll be able to suck him in with the poltergust 3000.
