How To Get All Gems On Each Floor | 14F & 15F Locations Guide
There are six gems on every floor of the Last Resort Hotel. To find them all, you’ll need to solve puzzles, reach hidden areas, locate gem ghosts, and more. There are many challenges hidden on each floor, and we’ll explain them all below.
14F: The Dance Hall
White Gem: Dance Floor – After defeating the boss, use Gooigi and Luigi to stand on the two unlit squares on the dance floor. You’ll make a Super Suction plug appear. Use it to reveal the hidden room behind the DJ Booth, and use the Strobulb on the light switch. Stairs will unveil in the Dance Floor — go up to the left side and use the Dark-Light to reveal a missing table. A Ghost Gem will appear.
Red Gem: Dance Floor – Use Luigi and Gooigi to suction the giant hanging records up both sets of stairs to make the disco ball drop with this gem.
Blue Gem: Dance Floor – Use Super Suction to destroy everything and clear the way to the DJ room. On the right, use Dark-Light on the shelves to make a wig appear. Pull off the wig to get the gem.
Green Gem: Elevator Hall – Enter the coat check room through the gift shop (use Slam!) and then suck up all the jackets on the left side.
Purple Gem: Elevator Hall – Use Suction on the two hanging records on the far left of the hall. Turn the records to make a brick block appear nearby. Use Gooigi to Slam (causing him to jump!) into the block. Hit it three times.
Yellow Gem: Elevator Hall – In front of the elevator, walk on the unlit floor lights until all of them are lit up. Then, summon Gooigi and stand on both unlit spots. Keep doing it until you complete the puzzle and unlock the path to the Secret Vault.
15F: The Master Suite
White Gem: Hallway – In the lower-left corner of the hallway, there’s a painting of King Boo. Use Suction to turn the small statue so the shadow matches the silhouette of King Boo — do the same for Luigi, and the paintings will reveal a hidden cabinet.
Red Gem: Library – Go to the left hidden room on the lower level and suck up the large book on top of the shelf. Take it upstairs and place it on the shelf to the right of the giant King Boo relief.
Blue Gem: Master Bathroom – Turn off the shower by using Suction on the faucet, then drop down into the sewer below with Gooigi. On the left, there’s a hidden passage with this gem.
Green Gem: Lounge – Use Luigi and Gooigi to stand on the round tables on both sides of the seating area.
Purple Gem: Lounge – To the left of the door to the hallway, enter the green pipe with Gooigi and drop down into the elevator shaft.
Yellow Gem: Master Bedroom – On the platform that raises up when you stand on the left / right sides, send Gooigi high up above the power switch. Only Gooigi can squeeze through the bars.
