Rather than 50 or so Boos to catch, Luigi’s Mansion 3 only has 16. That’s one for every floor except the final floor, where Helen Gravely resides.
Here’s where all the Boos in Luigi’s Mansion 3 are, how to get them, and what you get once you clear them all out.
How to Catch Boos in Luigi’s Mansion 3
How you catch boos hasn’t changed much since Luigi’s Mansion: Dark Moon. They don’t appear on a floor until after you’ve cleared out the boss ghost.
After uncovering their location(s), shine the Dark Light on them so they can’t turn invisible, then use the Polgergust to grab them by the tongue.
What comes next is a bit different. Luigi uses the Slam move to knock the Boos around. Unlike with regular ghosts, though, you get 10 chances to Slam the Boo. So keep mashing “A” until it escapes. Then do it all one more time to cram the Boo in the Poltergust for safe keeping.
If you’re not playing with HD Rumble, you won’t feel any haptic feedback when you get close to a Boo. If you do miss the cue or just make a mistake, the Boo will fly out of its hiding place and go into a nearby room to hide again. Try it all once more until you catch it.
It seems where a Boo appears on a specific floor isn’t the same for each player, so while we’ve striven for accuracy in pointing out specific rooms, we also recognize when it’s likely you could find a Boo in a different area. Additionally, the exact location (i.e., dresser, toilet, trash can) will probably be different for you, even if the room is the same.
Floor B1F Boo: Boosement
This one is lurking in the laundry room. We found it by entering from the right, moving in front of the dresser against the left wall, and interacting with it. Out popped Boosement.
Floor 1F Boo: Gumboo
Gumboo is in the Lobby area. Some found it in the gargoyle near the door, but we also found it hiding in one of the tables near the elevator.
Floor 2F Boo: Booigi
Most people are finding Booigi in the Mezzanine bathrooms, the one with fruit all over the place, although one or two found it hidden away in the Dressing Room table.
Floor 3F Boo: Kungboo
There’s a bit more consensus for where Kungboo is; nearly everyone found it in the telephone at the end of the corridor outside the elevator area.
Floor 4F Boo: Boogie
Boogie is in the women’s bathroom in front of the stage on the Great Stage floor.
Floor 5F Boo: Booldog
This one varies a bit as well, though the most common location for Booldog is in E.Gadd’s room (last one on the right, Room 508).
Floor 6F Boo: Boo-at-Arms
Everyone seems to find Boo-at-Arms in a different location.
Some found it in the area overlooking the Coliseum, some in the room right next to that, and some in the first room with the spike trap; for what it’s worth, we found Boo-at-Arms in the room leading to the Coliseum, in a suit of armor.
Floor 7F Boo: Bootanist
The Bootanist is pretty much consistently in the Thorny Bathroom, probably in the tub or the sink.
Floor 8F Boo: Booducer
The Horror Set seems to be the most common place for Booducer on the Paranormal Productions floor, but it could be lurking in any of the four main set areas.
Floor 9F Boo: Boones
Boones is hidden in one of the paintings in the Unnatural History Museum’s main exhibit area.
Floor B2F Boo: ComBooster
Down in the Boilerworks’ Main Tank area, you’ll come across ComBooster in the fridge — probably. Some found it in the nearby valve room outside the elevator.
Floor 10F Boo: AnuBoo
AnuBoo is more than likely in the Scale Chamber of the Tomb Suites floor. If not there, try the Snake Chamber.
Floor 11F Boo: Boofuddler
Head to the Trainer’s Room in the Twisted Suites, and you should find Boofuddler in the fridge at the back.
Floor 12F Boo: Booccaneer
This one’s up for grabs, really.
We found Booccaneer in the keg on the Beach right when you enter that area, but some found it on the Pirate Ship, and others as far away as in the Grotto Lounge Fortunately, The Spectral Catch is a pretty small floor, so there aren’t that many places to look anyway.
Floor 13F Boo: Boodybuilder
Boodybuilder (yes, that’s really it’s name), could be in the Yoga Room or it could be hiding out in the Pool Room.
Floor 14F Boo: Boosician
Boosician is more than likely near the elevator. It could be as we found it above, near the trash can. Or it could be in the gift shop nearby or the coatroom (also nearby).
What Do You Get For Catching All the Boos?
That’s a good question! And the answer isn’t quite as good. Other than the fun of hunting them down and capturing them, you get an attachment for Luigi’s flashlight that projects a Boo image onto the wall. Oh well.
That’s it for how to catch Boos in Luigi’s Mansion 3 and where to find all Boos, but be sure to check out our other Luigi’s Mansion 3 guides as well.
