2F Mezzanine Gem Locations
The 2F Mezzanine Gems are spread across the Restroom, Ball Room, Kitchen Room, Dressing Room, Entertainment Room and Hallway. The Blue Gem is locked behind the Chef ghost boss fight, so sweep the other five rooms first and return to the Kitchen once the boss is defeated.
White Gem #1 – Restroom
- Head to the Restroom on 2F Mezzanine and aim the Plunger at the middle stall door.
- Pull the door open with the Plunger. A hidden ghost jumps out of the stall.
- Defeat the ghost with the Poltergust so it bursts apart and drops the White Gem.
Red Gem #2 – Ball Room
- In the Ball Room, aim the Poltergust G-00 at the hanging chandelier and vacuum it until it spins.
- Spinning the chandelier opens a secret door at the back of the room.
- Go through the secret door and collect the Red Gem from the sheeted furniture inside.
Blue Gem #3 – Kitchen Room
- Defeat the Chef ghost boss on 2F Mezzanine first. The Blue Gem will not appear until he is gone.
- Return to the Kitchen Room, turn on the stove, then summon Gooigi to hold a block of ice above the flame.
- Let the ice melt over the fire to release and collect the Blue Gem.
Green Gem #4 – Dressing Room
- In the Dressing Room, use the Poltergust to vacuum the hanging clothes on the left wall.
- A hidden safe appears behind the clothes rack once the clothes are cleared.
- Flash the Strobulb on the safe’s dial to pop it open and collect the Green Gem.
Purple Gem #5 – Entertainment Room
- In the Entertainment Room, use Suction Shot to pull the sword mounted on the wall to the right.
- Aim the sucked-up sword at the dartboard on the far wall and fire it.
- Defeat the dog ghost that appears to claim the Purple Gem.
Yellow Gem #6 – Hallway
- Go to the Hallway and use the Plunger on the fish-shaped sign at the end, beside the carved double doors.
- Summon Gooigi, then have Luigi and Gooigi blow into both wall fans at the same time.
- The double doors react to the fans and release the Yellow Gem.
