Another Timed Ghost Hunt
Disturbing… I receive clear paranormal signals from the ivy towers. Luigi, you are on the train!
After you catch all the boos in the ivy towers, this mission is available. For the locations see either in the corresponding section of the walkthrough or here. Your task is to find all the spirits as soon as possible. Go from the yard to the left into the sapling house. Vacuum in all the spirits and return to the courtyard. Now use the door on the right and remove all ghosts at the water generator. Go up the stairs and also clean up in the botany laboratory. Your next destination is the Bathroom. After that, only Family Room and Sapling House are to free ghosts. After that, the mission is over.
