A Train to Catch

E-3: A Train to Catch is the third mission of the Treacherous Mansion in Luigi's Mansion: Dark Moon.

Plot
E. Gadd tells Luigi that one of the Toads from the previous mission has got a security image (which was fixed due to an unknown cause) and they should have a look at the image.

When it is first looked at, Luigi looks at the portrait the Boos have been dragging all over the valley, it is shown this is Mario, who has been captured and brought to the Train Exhibit. They both look at the security image. Before the player is done looking at it and presses the B button, E. Gadd tells them that one of the Boos is very strange compared to the others. When they zoom in at this Boo, it is revealed to be King Boo, who scares both of them and jams the security image. Luigi is then pixelated to the Front Entrance.

Once done, Luigi must go to the Inner Courtyard and put the rotator on the thing used to get to the second floor, Luigi can visit most of the rooms on either side, but most importantly has to go to the Study.
