Luigi's Mansion 3: How to Find and Beat Polterkitty
One of Luigi's Mansion 3's biggest attractions is the return of boss ghosts with unique personalities, such as the Portrait Ghosts from the original game. One of the trickiest is Polterkitty, also known as Polter Kitty. The first time you face off against Polterkitty in Luigi's Mansion 3 is roughly halfway through the game, and it's a multi-part fight spanning two floors and some deadly hide-and-seek.
Fear not, though. We've laid out how to beat Polterkitty. Here's what you need to know.
Polterkitty: Round One
Poor Luigi just wants to collect elevator buttons, but the hotel ghosts have different plans. This time around, it's Polterkitty who steals the elevator button for Floor 9 after you finish the Godzilla-adjacent battle on the Production Floor. From here, you'll need to track Polterkitty down and start the boss fight.
Polterkitty's first location is on Floor 8 (Paranormal Productions), in the Fire Set, under the bench. If you're having trouble finding it, just use the Dark Light function on Luigi's flashlight to uncover its spectral tracks.
Examine the furniture like you would any other object, and out pops Polterkitty, none too happy to see you.
Polterkitty Boss Fight
Polterkitty acts a lot like a Boo. You can't face or attack it directly. Instead, face the other way, and Polterkitty will start to stalk you.
When Polterkitty rears back ready to strike, turn around, charge the Strobulb by holding "A," then release to stun Polterkitty, the same as with other ghosts.
Should you find the timing a bit difficult, you can always position Gooigi behind Luigi, facing Polterkitty, and quickly switch control to Gooigi. Polterkitty doesn't pay Gooigi any attention, so you don't need to worry about him getting harmed.
The ensuing fight plays out the same as with other ghosts as well — latch onto Polterkitty with the Poltergust, pull the opposite direction, Slam, and repeat.
You'll need to do this three times. Each time, you pull off one of Polterkitty's tails, but after the first phase, Polterkitty retreats to the Backstage area and then moves on to Floor 7 after you find it there.
How to Catch Polterkitty on Floor 7
Polterkitty's first hideout on Floor 7 is the Blooming Suite on Floor 7, in the wardrobe. Like before, use the Dark Light if you're having trouble finding it.
After phase two of the Polterkitty boss fight, the spectral feline goes to the Ivy Bathroom on Floor 7. It's lurking in the faucets, and depending on what you did the first time you were here, you might need to repair the pipes under the floor to flush Polterkitty out.
To do that, use Luigi and Gooigi to move the giant watermelon out of the way, then use the Dark Light to uncover a hidden drain on the floor. Send Gooigi into the drain, uncover a vanished pipe beneath the floor with the Dark Light, and turn the taps on with Luigi back above ground.
Polterkitty: Round Two
Polterkitty escapes this fight, and you'll be seeing it again after defeating Johnny Deepend on Floor 13, as Luigi tries to make his way to Floor 14. This time around, though, the Polterkitty fight spans three floors, 13, 12, and 11.
Polterkitty Floor 13
It first hides in the boxing bag in Floor 13's Weight Room. You'll need to use a suction shot to launch one of the boxing gloves into the bag. Afterward, you don't actually fight Polterkitty and are, instead, forced to face off against a horde of ghosts while Polterkitty watches.
After your victory, follow Polterkitty's tracks into the weight room. You'll enter a reception-type area and see Polterkitty dangling from a bar overhead. When it lowers itself, flash it with the Strobulb to start the fight.
Polterkitty Floor 12
Follow Polterkitty down to Floor 12, The Spectral Catch, and trace it to the beach area. After clearing out the enemies already there for convenience, check out the barrel in the middle of the sand. Polterkitty leaps out, and the fight begins again after you successfully flash it with the Strobulb.
Polterkitty Floor 11
Make your way down to Floor 11 after that and follow Polterkitty to the room with the hats. It's hiding under one of them and runs off to the stage room after you uncover it. Use Luigi's special jump ("ZL"+ "ZR") to lift multiple hats at once.
Polterkitty is in the casket on stage that has swords sticking into it. You'll need to use Luigi and Gooigi to fire a plunger shot at each front panel, then pull them off simultaneously. The fight commences, and at last, you capture Polterkitty and can go up to Floor 14.
It's a lengthy process, but that's all you need to know for how to beat Polterkitty in Luigi's Mansion 3. Be on the lookout for our other Luigi's Mansion 3 guides on GameSkinny in the coming days.
