Finding all the hidden Boos in Luigi’s Mansion 3 can be an exciting challenge that enhances your ghost-hunting experience. Below is a comprehensive guide on how to locate these elusive spirits, outlining their locations floor-by-floor and providing you with helpful tips to ensure you successfully capture each Boo.

Understanding Boos
Boos are playful ghosts that can only be revealed using the Dark Light feature of your Poltergust G-00. In total, there are 16 Boos hidden throughout the hotel, with one located on almost every floor except the 15th.

Essential Tools
– Poltergust G-00: This high-tech vacuum is indispensable for capturing Boos once they’re revealed.
– Dark Light: An attachment of the Poltergust G-00 that reveals invisible objects, including the sneaky Boos.

Step-by-Step Guide to Capturing Boos
1. Locate the Boo: Utilize the Dark Light to uncover the Boo’s hiding spot. Boos might create clear areas in ghostly fog or alter common objects, signaling their presence.
2. Capture the Boo: Once the Boo is revealed, activate the Poltergust G-00 to suck it in and capture it.
