A Train to Catch
In the opening cutscene in the Bunker, Professor E. Gadd informs Luigi he has repaired the image brought back from the Treacherous Mansion, and it is a very recent photo. As soon as he tells Luigi this, they look at the image that was taken, and see the sack with the mysterious painting the Boos had been carrying around, only to discover that Mario has once again been trapped inside a painting. After noting that they are in the Train Exhibit, they notice a very unusual Boo. Suddenly, the Boo turns around and gets right in the camera, laughing maniacally, revealing himself to be King Boo, and he causes the picture to disappear into static. The duo realize that it was King Boo who had been "pulling the strings the whole time", and, after a quick inspection on the Parascope, they find that large paranormal readings are emanating from the Train Exhibit. Finally, after giving Luigi a makeshift rotor for the stairwell in the Inner Courtyard and a thought that his brother needs him, E. Gadd sends Luigi to the mansion.
Upon arrival at the Inner Courtyard, Luigi can attach the rotor to the statue, allowing access to the second floor. Once up there, Luigi will have to enter the Train Exhibit via the Study. After revealing a book on a table with the Dark-Light Device, Luigi can take it and put it in the slot in the bookcase. However, a yellow hand pushes the book out, and after looking through the hole, a Strong Poltergeist scares Luigi, steals the book, and leaves.
After a quick search with the Parascope, E. Gadd informs Luigi that he cannot specify where the ghost is, only that it is on the west side of the mansion. Before this, Luigi should head for the Nautical Exhibit and clear the ghosts in that room, activate the E-Gate, and spin the wheel so the E-Gate points into the Study.
On the west side of the mansion, Luigi can reveal a hidden door leading to the Space Exhibit. After activating the E-Gate in the exhibit, Luigi can look through the telescope to see the Strong Poltergeist on a planet with an asteroid belt surrounding it. When Luigi looks up from the telescope, he will have been transported to the planet, and the battle with the Strong Poltergeist begins. After beating the paranormal baddie, Luigi will be transported back to the Space Exhibit, where he can take the recovered book back through the E-Gate and place it on the bookshelf. After doing so, the shelf disappears into the floor, and Luigi can enter the Train Exhibit. After entering and defeating the ghosts in the exhibit, Luigi can look in the miniature Train Model and see the painting, with tiny Boos around. After a Boo surprises him, E. Gadd calls Luigi and pixelates him back to the Bunker. Once there, E. Gadd reassures Luigi that they will get Mario back. He then says how he noticed a tiny camera he could potentially pixelate Luigi to where he could rescue his brother.
The Toad curators brought a security camera image back with them. Maybe it'll give us some clues about the next Dark Moon piece.
