Luigi’s Mansion 3’s fifth floor — 5F : FIP Suites — has six hidden gems. In this guide, we’ll show you their map locations and how to find them all throughout the level.
On every floor, gems appear in the same order from left to right in the menu: clear, red, blue, green, purple, and finally yellow. We’ll follow the same order below.
5F ROOM 508 [CLEAR GEM]
Open the door and head out onto the balcony. Look through the telescope, and fight the ghost who appears. Defeat it for the gem.
5F ROOM 501 [RED GEM]
Have Luigi and Gooigi both shoot a plunger at the couch blocking the left path, so they can use their combined strength to smash it.
Shine your Dark-Light on the wall just past where the couch was, to reveal the hidden door for room 501. Suck up the orbs that appear, and enter the room.
Once again, shine your Dark-Light on the wall, this time at the top right of the room. That’ll reveal another door and more orbs to suck up.
Exit through the door onto the patio.
Take an immediate right, and walk along the path up to the gargoyle. Take the red gem right out of its mouth.
5F LAUNDRY ROOM [BLUE GEM]
Use your plunger on the grate in the upper left corner of the room, and this will be behind it.
5F HALLWAY [GREEN GEM]
You’ll see this green gem in the teeth of a lion on the wall between rooms 505 and 506, but you won’t be able to suck it out. Instead, suck up the ball on the wall to the left of the lion, and throw that at the lion. That’ll destroy the lion but leave the green gem for you to collect.
5F ROOM 507 BATHROOM [PURPLE GEM]
Suck the sheet in the upper left corner of the room to reveal a hidden room north of the bathroom. This crystal is to the right of that room. You can walk over to it. Just use the plunger on the chest to move it first, and that’ll create a path.
5F ROOM 502 BATHROOM [YELLOW GEM]
You’re going to have to work for the final gem, so we’ve broken it down into a series of bite-sized steps.
- Shine your Dark-Light on the wall past room 501 to reveal a hidden door for room 502. Suck up the orbs that appear, and enter the room.
- Use your plunger on the cart blocking the door on the left, and go through the door into the bathroom.
- Become Gooigi, walk onto the grate in the middle of the bathroom floor, and ooze your way down to a room beneath the bathroom.
- Shoot your plunger at the boards in the middle of the room, and pull them loose.
- Use some suction to move the needle and the water to your left.
- Open the chest to collect some money.
- Double-click R3 to become Luigi (because you don’t need to be Gooigi anymore).
- Suck up the shower curtain if you haven’t already, and use your Poltergust to push the knob and turn the shower on. That’ll fill the bath and eject a little suitcase.
- Use your plunger to break the little suitcase and claim this floor’s final gem.
