After this Greenie is defeated, two more wearing sunglasses appear. In order to defeat this Greenie, Luigi should suck up the sunglasses, then use the Strobulb on it to suck it in. Just as in Gear Up, Luigi should suck the blackboard, flipping the ghost until it is thrown out. In the Lab, Luigi sees the Dark-Light Device as soon as he is about to take it, however, a Greenie with sunglasses jumpscares him and takes the Dark-Light Device, and it hides in the blackboard. As he enters the room, the fire in the fireplace goes out, enabling Luigi to use it to access the Lab.

As soon as all ghosts get defeated, the room lightens up and Luigi has access to the second floor. Once the Hider has been defeated, two more appear. If Luigi goes up the stairs, however, the room turns dark and the stairs slide him down to the bottom, similar to what happens in Gear Up. Luigi has to find another way to access the Lab he should go upstairs to find a way down. When Luigi arrives at the door, it disappears due to the presence of Spirit Balls. Luigi has to go to the Lab to retrieve the Dark-Light Device.
