Find all six gems in 2F — Mezzanine. The colours are white, red, blue, green, purple and yellow. Gem collection is separate from the ending money rank; completing all seventeen floor sets unlocks Suction Shot Type-C.
Required tools and return visits
Unlock Gooigi and the Dark-Light Device before completing the floor. Clear the story route first if a door or room mechanism remains locked.
White gem — Men’s Restroom
Pull off the third cubicle door. Vacuum the floating newspaper to uncover a crystal ghost, then capture it for the white gem.
Red gem — Ballroom
Spin the chandelier with the Poltergust until the side shutters open. Enter the exposed alcove and take the red gem.
Blue gem — Kitchen — freezer ice
After Chef Soulfflé, open the left freezer and take the ice block from its shelf. Carry it to a lit cooker in the kitchen and melt it. Avoid the freezer’s fish while collecting the block.
Green gem — Dressing Room
Vacuum the clothes from the rail until the wall safe is exposed. Flash its green sensor and collect the gem.
Purple gem — Entertainment Room
Vacuum a sword from the wall display above the billiard table. Fire it into the dartboard on the rear wall to open the gem compartment.
Yellow gem — Restaurant corridor — paired fans
Remove the menu board hiding one wall fan. Keep Luigi’s vacuum on one fan and switch to Gooigi for the other. Turn both together to release the yellow gem.
Six-gem check
Open the floor collection screen and check all six colour slots. A missing colour identifies the exact entry to revisit above. Gem ghosts must be fully captured before their gem is awarded.
