The Treacherous Mansion serves as the climactic finale of Luigi’s ghost-hunting adventure, and finding all its hidden Boos is essential for unlocking the bonus mission and achieving 100% completion. These mischievous spirits are masters at hide-and-seek, but with my detailed guide and the Dark-Light Device, you’ll capture every single one.

Luigi’s Mansion 2 HD: Detailed Treacherous Mansion Boo Locations

E-1: Front-Door Key – Boolldog

The first Boo in Treacherous Mansion awaits in the Underground Lab, and catching Boolldog requires a bit of electrical work.

Step-by-Step Guide:

Make your way to the Underground Lab
Defeat all the green and purple ghosts in the room
Locate the wheel mechanism at the back of the room
Use the Poltergust 5000’s vacuum function to turn the wheel
Keep turning until the meter reaches the red zone
This sends electricity through the knight’s armor suit in the center
Boolldog will appear after the shock

Pro Tip: Make sure to clear all enemies first, as trying to turn the wheel while being attacked makes this much harder!

E-2: Double Trouble – Boopa Troopa

Boopa Troopa presents one of the more puzzle-oriented Boo captures in the game, requiring you to work with both Toad companions.

How to Find Boopa Troopa:

First, locate and rescue both Green Toad and Purple Toad
Guide them to the Inner Courtyard on the first floor
Look for the statue with two cages/scales in the middle of the courtyard
Use your Poltergust to launch Green Toad into one cage
Launch Purple Toad into the other cage
Once both Toads are properly placed, Boopa Troopa appears
This triggers a mandatory boss fight

Important Note: You cannot skip this Boo – it’s required for mission progression!

E-3: A Train to Catch – Booreaucrat

Booreaucrat might be the trickiest Boo to capture in Treacherous Mansion, requiring precise timing and platforming skills.

Detailed Capture Method:

Enter the Study after activating all portals
Ensure the Nautical Exhibit’s portal has been moved to the Study
Grab a purple balloon from the back of the Study
Use the portal to travel to the Dark Age Exhibit
Inflate the balloon to float up to the upper level
Float to the right side of the room
Land on top of the bed (don’t pop the balloon yet!)
Replace your purple balloon with the gold balloon
A timed coin challenge begins – coins form a Boo shape in the air
Collect ALL coins before time runs out
Success spawns a treasure chest on the ground floor
Open it to reveal Booreaucrat

Challenge Tip: Practice the coin route once before attempting with the gold balloon, as you only get one shot per mission attempt!

E-4: Ambush Maneuver – Big Boo

Big Boo serves as both a boss fight and a Boo capture, counting as 10 regular Boos toward your collection!

Boss Fight Strategy:

Enter the Train Exhibit on the second floor
Dodge Big Boo’s charge attacks by moving side to side
Wait for Big Boo to tire and stick out his tongue
Grab the tongue with your Poltergust
Aim and launch Big Boo at the front of the train
This scatters him into multiple smaller Boos
Capture each small Boo by grabbing their tongues
Aim and shoot them into different train carriages
Repeat until all Boos are captured

Battle Tips:

Stay mobile to avoid attacks
The fight gets harder as fewer Boos remain
Each captured Boo reduces Big Boo’s health

E-5: Paranormal Chaos – MaraBoo

The final Boo in Treacherous Mansion requires quick action during a timed mission segment.

MaraBoo Location Guide:

Before heading to the Terrace (mission objective)
Enter the Aviation Exhibit on the second floor
Look for the missing hot air balloon in the room’s center
Use your Dark-Light Device to reveal the balloon
Collect all Spirit Balls that appear
MaraBoo will materialize after the balloon is restored

Critical Warning: This level has a time limit! Capture MaraBoo BEFORE going to the Terrace, or you’ll miss your chance and need to replay the entire mission.

Essential Boo-Hunting Tips

Dark-Light Device Mastery

Always scan rooms thoroughly with the Dark-Light Device
Look for subtle visual cues like missing objects or furniture outlines
Spirit Balls must ALL be collected for objects to fully materialize

Boo Capture Technique

Use Dark-Light to reveal invisible Boos
Flash them with the Strobulb when they materialize
Grab their tongue with the Poltergust
Pull and slam them to deal damage
Repeat until their HP depletes
Final vacuum capture when they’re defeated

General Strategies

Save your game after capturing each Boo
Some Boos only appear after clearing all enemies
Check every room, even if it seems empty
Boos love hiding near or inside restored objects

Treacherous Mansion Overview

Frequently Asked Questions

Can I replay missions to find missed Boos?

Yes! You can replay any mission from the mansion selection screen to capture Boos you missed. Your Boo captures are saved even if you don’t complete the entire mission again.

Do I need the Dark-Light Device for all Boos?

Yes, the Dark-Light Device is essential for finding and capturing all Boos in Treacherous Mansion. You’ll have it by the time you reach this mansion.

What happens if I defeat Big Boo?

Big Boo counts as 10 regular Boos toward your total collection of 32. This is why there are only 23 regular missions with Boos but 32 total Boos to collect.

Can I capture MaraBoo after the mission timer starts?

While technically possible, it’s extremely risky. The mission timer is tight, so I strongly recommend capturing MaraBoo before triggering the final sequence.

Do Treacherous Mansion Boos have higher HP?

Yes, Boos in later mansions generally have more HP than earlier ones. Treacherous Mansion Boos require 3-4 slam cycles to defeat.

Is there a reward for getting all Treacherous Mansion Boos specifically?

Collecting all 5 Boos unlocks the mansion’s bonus mission “Terrifying Invasion,” which must be completed with 3 stars for 100% game completion.
