Gradual Infiltration

A-Bonus: Gradual Infiltration is a bonus level in Gloomy Manor from Luigi's Mansion: Dark Moon. It is unlocked after Luigi clears the mansion's boss level, and captures five Boos from previous missions.

Overview
Luigi has to capture all ghosts in a room in the shortest time he can. The order of the rooms and the amount and variety of ghosts are randomized every time Luigi does this mission. After clearing the fifth room, the mission is completed.

Objectives

 * Capture all the ghosts as soon as possible!
 * (rooms are randomized)

Description
''We have an...interesting situation. The Parascope is picking up mild paranormal signals in the manor. I'm sending you in to investigate.''

Messages
When clearing the Gloomy Manor of ghosts, what E. Gadd will say to Luigi at the end of the mission differs depending how quickly Luigi completes it:

"That'll do, Luigi! You weren't exactly quick about it, but you caught 'em all. Anyhoo, let's bring you back!" (Time over 4 minutes)

"Excellent, Luigi! You got all of 'em! That was really fast! The very definition of posthaste! Heh heh... Let's bring you back!" (Time under 4 minutes)
