Luigi's Mansion 3 presents players with complex puzzles and hidden collectibles scattered across the many floors of the Last Resort hotel. Among these environments, the pirate-themed 12th floor, known as the The Spectral Catch, holds six unique gems that require creative tool usage to collect. Finding all these collectibles requires a combination of Luigi's Dark-Light Device, Suction Shot, and assistance from Gooigi.
Finding the Red and Blue Gems in the Beach Area
The Red Gem is located on the beach section before entering the main ship area. Players must use Gooigi to dig up a hidden chest buried in the sand on the far left side of the shore. Using the Suction Shot on the chest reveals the gem, making it accessible for Luigi to claim.
For the Blue Gem, navigate toward the right side of the beach area near the large statue. Use the Suction Shot to destroy the surrounding structures and reveal a hidden pathway leading behind the terrain. Following this path leads directly to the blue collectible tucked away in a small alcove.
Unlocking the Green and Yellow Gems On Board
The Green Gem is concealed inside the lounge area onboard the pirate ship. Players need to locate the hidden floor hatch using the Suction Shot to pull open the heavy wooden plank. Drop Gooigi into the lower compartment to retrieve the gem sitting safely below the floorboards.
To obtain the Yellow Gem, head over to the main deck near the ship's mast. Use the Suction Shot on the nearby barrel to break it open and reveal a hidden pulley mechanism. Interacting with the pulley lowers a wooden crate containing the yellow collectible.
Locating the Purple and Clear Gems in Secret Areas
The Purple Gem requires using the Dark-Light Device near the chest located in the upper cabin. Shining the light reveals a missing set of pipes that must be reactivated. Once the pipes appear, send Gooigi through them to reach the high ledge where the purple gem rests.
The Clear Gem is obtained inside the storage room hidden behind the bar. Use the Suction Shot to clear away heavy crates blocking the rear wall, then shine the Dark-Light Device to uncover a hidden door. Head inside the secret compartment to pick up the final collectible of Floor 12.
Tips for Completing Floor 12 Collection
Completing the gem collection on Floor 12 requires careful observation of environment details like loose sand and invisible objects. Returning to previous areas after acquiring new abilities ensures you do not miss any well-hidden secrets. Utilizing both Luigi and Gooigi in tandem remains the most effective strategy for solving every environmental puzzle on this floor.
