Find the Dark-Light Device

Once you arrive in the Entrance, you'll notice that one of the suits of armor is missing. Run through the Guard Hall into the Foyer. Take the door on the left to get to the Common Hall. Go down the Common Hall to reach the Lab. The door will vanish when you approach it. Answer the DS call, then go back to the Foyer and go up the stairs.

When the flames on the candles change color, it means a hidden ghost is nearby. Go back to the center of the Foyer, and you'll find a Hider and a Slammer. Use your Strobulb on the Hider before it hides into an object. After capturing both ghosts, two more hiders will join in. Once all 4 ghosts are captured, you can go up the stairs without worries.

Go through the door on the left at the end of the stairs to reach the Master Hall. Head to the Parlor, the room directly above the Lab. Once you enter the Parlor, interact with objects in the room to trigger a cutscene. Spirit Balls will fly in from the fireplace and the clock will have disappeared. Inspect the now-extinguished fireplace to get to the Lab.

The Dark-Light Device is found on the upper east corner of the room. A Greenie will grab the Dark-Light Device when you try to get it. It will take the device through the chalkboard. Use the Poltergust on the chalkboard to vacuum the Greenie back to the Lab.

Vacuum the sunglasses from the Greenie before you use your Strobulb to stun it, then capture as you normally would. Two more Greenies will appear, capture them all the same to get the Dark-Light Device. After answering the call from E. Gadd, use the Dark-Light Device to reveal Spirit Balls in the area. Capture all the Spirit Balls to reveal the door.

Capture Whoever is Releasing the Spirit Balls

After exiting the Lab, answer the call from E. Gadd. Go back to the Foyer and head for the Entrance. Inspect the vases for a Gold Bone. Go to the Front Yard and use the Dark-Light Device on the fountain to reveal the Spirit Balls. Capture the Spirit Balls and get lots of treasure.

Head to the Garage and you'll find a Gold Greenie to capture hiding in the car. Go back in the Entrance and use the Dark-Light device on the painting on the east wall to get lots of treasure.

Use your Strobulb on the door in the Mudroom to get to the Mudroom Exterior. You'll notice that doghouse is now missing. Shine your Dark-Light Device on the doghouse to reveal some more Spirit Balls. Capture the Spirit Balls to reveal a bonus challenge in the doghouse. Complete the challenge by capturing the Spirit Balls inside the doghouse for bonus treasure.

Head up the Foyer and go to the westernmost door leading to the Master Hall. Go to Bedroom past the Master Hall and interact with the bed to be taken to the Study.

Use the Dark-Light Device on the painting on the northwest wall in the Study to get the Spindle Amethyst. Roll up the carpet with the Poltergust to reveal a floor switch. Step on it extinguish the flames of the fireplace, then you can use it to get down to the Studio.

Exit to the Common Hall and go up the hall to the giant web. Use the Dark-Light Device on the painting to get the Key. Use the Dark-Light Device again on the wall next to the painting, to reveal the Spirit Balls. Capture them to reveal the door to the Patio.

Explore and interact with objects in the area to get treasure. Shine the Dark-Light Device on the west portion of the Patio to reveal a hidden door. Go through Under the Stairs to reach the Star Amethyst behind the aquarium in the Foyer.

Head back to the Patio and use the Dark-Light Device on the fountain to reveal Spirit Balls. Capture the balls to get the Octagon Amethyst.

Shine the Dark-Light Device on the missing E. Gadd statue, then capture the Spirit Balls that emerge. Blow on the propellor atop the statue. This will reveal a hidden compartment containing a Key. Get the key to open the door to the Kitchen from the Patio.

Inside the Kitchen is a couple of Greenies and Hiders. Capture the ghosts to get to the next room. Go to the Library. Shine the Dark-Light Device on the Globe by the ladder to spawn some Spirit Balls. Capture these to reveal the globe. Vacuum the globe in the library using the Poltergust, and fire it towards the fireplace to reveal a hidden gem inside it.

Head back into the kitchen and ride the dumbwaiter to the Dining Room to reveal the Boo. After the cutscene, shine the Dark-Light Device on the missing table, then catch all the Spirit Balls that emerge. Undoing the Boo's work will spawn it. Use the Dark-Light Device to find the Boo when it hides, then suck it up with the Poltergust. Capturing the Boo will complete the mission.
