Luigi’s Mansion 3 brings back the series’ classic ghost-hunting challenge—tracking down and capturing Boos hidden throughout the haunted hotel. These mischievous spirits are concealed across the floors of The Last Resort, waiting for the player to uncover their hiding spots using Luigi’s upgraded ghost-hunting gear. Unlike standard ghosts, Boos are particularly elusive, demanding patience, careful observation, and an understanding of how the game’s HD rumble system works.
While finding Boos may seem daunting at first, once you understand their patterns and behaviors, the process becomes a satisfying side quest that complements the main story. Capturing all Boos not only rewards players with completion bonuses but also deepens the thrill of exploring each themed floor of the hotel.
How to Find and Capture Boos
Boos are hidden inside random containers on every floor of The Last Resort Hotel. Their positions are not fixed, meaning they may appear in different rooms across playthroughs. To locate them, rely on your controller’s HD rumble feedback—as Luigi approaches the correct hiding spot, the vibration intensity will increase, signaling the Boo’s presence.
When you interact with the correct container, the Boo will reveal itself and the battle will begin. If you choose the wrong one, the Boo will summon a swarm of bats to attack Luigi. To capture a Boo, use the Dark-Light Device to reveal its true form. Once exposed, the Boo will be disoriented with its tongue sticking out—grab it using the Poltergust G-00, then slam it repeatedly on the floor until it’s defeated. Most Boos require this process to be repeated two or three times before being fully captured.
All Luigi’s Mansion 3 Secret Boo Locations
Below is the list of all known Boos in Luigi’s Mansion 3 and the floors where they appear:
- Boosement – B1 Basement
- Gumboo – 1F Grand Lobby
- Booigi – 2F Mezzanine
- Kung Boo – 3F Hotel Shops
- Boogie – 4F The Great Stage
- Boolldog – 5F RIP Suites
- Boo-At-Arms – 6F Castle MacFrights
- Bootanist – 7F Garden Suites
- Booducer – 8F Paranormal Productions
- Boones – 9F Exhibit Hall (Unnatural History Museum)
- Anuboo – 10F Egypt Suite (Tomb Suites)
- Combooster – B2 Boilerworks (Note: Only appears after rescuing Toad and revisiting this area.)
- Boofuddler – 11F Twisted Suites
- Booccaneer – 12F The Spectral Catch
- Boodybuilder – 13F Fitness Center
- Boosician – 14F The Dance Hall
Since Boo hiding spots are randomized, the best approach is to methodically explore each room on the floor while paying attention to rumble feedback. Once the vibrations become stronger, interact with nearby containers, boxes, or decorative objects to trigger the Boo encounter.
Tips for Capturing Boos Efficiently
- Use both Luigi and Gooigi. Some Boos can move through grates or obstacles, so switching between the two characters can help corner them faster.
- Track vibrations carefully. The HD rumble grows stronger the closer Luigi is to the hiding spot—use this as your primary guide.
- Avoid unnecessary interactions. Opening too many containers randomly can trigger bat swarms that interrupt your progress.
- Stay mobile during battles. Boos move erratically, so use the Poltergust’s suction and burst functions to keep them within range.
- Revisit missed floors. Some Boos only appear after story milestones, so returning to earlier levels later in the game may be necessary.
Rewards for Capturing All Boos
Catching every Boo in Luigi’s Mansion 3 contributes toward your completion percentage and unlocks special rewards and cosmetic upgrades. While the exact reward varies depending on completion order, capturing them all is one of the key challenges for 100% completionists.
