Gear #1
We absolutely must find the pieces of the dark moon! The paranormal signals from the northern part of Gloomy Manor are particularly strong. That is where we will continue!
First, go to the foyer where you can watch the gears being stolen. If you try to walk through the door, close it and a Greenie man flees with the key. Follow him into the Entrance and vacuum him up. Return and walk through the door to the left. Here you can pull off the wallpaper on the wall and reach a wall gap, where you will find a key.
Take it through the front door in the Common Hall. Use the Poltergust to turn the board and reveal the ghosts. Capture the Greenies, then the Slammer that appears. Once the room is clear, collect the gear.
Gear #2
Now go back to the foyer and try to take the stairs up. You slip and a Hider appears. Now find it in the different furniture and soak it up.
After that, you can take the stairs up and open the door. Vacuum a little on the gramophone here for a melody to sound. After a short time, the ghosts appear and you can vacuum up them all. Once you have received the second gear, you can fire a flash of light against the clock to get another gem.
Gear #3 and #4
Leave the room and go to the bedroom. If you vacuum up the long red pull cord on the door here, you can drop the bed. Sit up there and you end up in the study. If you try to vacuum up the gear here, the ghosts appear. After four Greenies, the Slammer is also there and waiting for his appearance. When all spirits are captured, the third gear is yours. Remove all curtains to get a few more coins. After that, you will find a switch under the carpet that lets the fire go out. Then examine the fireplace to get to the studio.
Here you look again for the Hider in some objects, then vacuum up the Slammer and collect the last gear. Now look through the camera to see a spider web by the curtains in the mirror. Soak this up for another gem to appear.
Then you try to use the gears to finish the level.
The Boo
After completing Mission A-4, you can make a table visible in the garden entrance in front of the carpet. If this one is back, the BaBoon also appears. Vacuum it in!
