Easy Energy:
1) Check the pots in the main corridors of the mansion - hoovering them hard usually causes them to spurt out a heart.
2) Remember that if you hoover more than 1 ghost at a time, hearts will appear.
3) Most lights, fans and sinks will give out hearts or money when hoovered.
Hidden Mansion:
After completing the main mansion, a new mansion will appear. It is the old mansion, but mirrored - also, your hoover is much stronger, and the ghosts are much harder!
Gold mice:
If you find a gold mouse, hoover it up quick - it will explode into loads of cash!
The locations of the gold mice are:
The 2nd floor study behind a desk.
The 1st floor dining room underneath a chair.
The 2nd floor dining room at the back.
The 1st floor room with the crystal ball behind the fortune teller.
The 3rd floor trophy room behind a chair.
The 2nd floor corridor near the stairs to the attic, you hear a chime and a mouse runs up the corridor.
Rank A:
To obtain an A rank, get all the gold mice, catch all the blue ghosts, get both gold diamonds, and collect as much money as possible. You need $100,000,000 to get an A. At the end of the game, Professor Gadd will build a huge mansion for you!
Two hidden rooms:
1) Go to the Butler's Room. Use the Game Boy Horror on the mouse hole, then get sucked into it.
2) After you defeat the Shy-guys on the roof, 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 secret room. The only way to exit is through the mirror warp.
Mirror Warp:
Use the Game Boy Horror on a mirror to warp back to the main hall.
Door Traps:
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. Brun them using the fire element to watch them melt away.
