Looking for something a little bit wilder to spice up your indefinite stay at The Last Resort? Then look no further than our Twisted Suites. Outside a puzzling stay in these optically illusive rooms, you can check out a live performance by our magical trio: Nikki, Lindsey, and Ginny.

What a perplexing floor, Luigi. You may have your work cut our for yourself here. These Mad Hatter girls are no joke. It looks like we need a key to chase after them. Use the plunger on that vending machine, I think I see a door behind it. Ah, I was right. Now pull down that wallpaper and use your dark light to reveal a door. Oof! The ghosts went into that vent, use Gooigi to track them down!

There it is! The key. Wait, what is that? A bunny? Quickly grab it before it gets away! Use Gooigi to hold it while you use your dark light to get that key. Use it to go into the room with the giant mirror! Keep after those three ghosts.  

A Show Unlike Any Other

Witness daring magical stunts, like a man holding his breath in a giant tank of water and a bed floating in mid air, it'll be an evening to remember for the rest of your life. However long that may be. All hosted by the wonderful trio of women wonders.

Prepare for the fight of your life Luigi! It looks like these ghost magicians are playing with the physical layout of the floor. Your gonna have to fight ghosts in every room until you find them. You've done this before so no sweat!

There they are, be careful of the playing cards they shoot. Use your vacuum jump to disorient them once they fly by in their hats! Be careful. Once you capture one of them, they'll add a bomb to the mix. The key is keeping your eye on one hat each time, until you've caught all three with the same method. Good luck!

I didn't think you'd pull through! Congratulations Luigi. I need you back at the Lab as soon as possible! I have bad news. 

Toad is missing...I sent him to get apart to update your vacuum and he has yet to return. I know he is down in the pipework system below the basement though in the boiler room (B2). Can you go down and get him and retrieve the part?

There he is, in the main room with the rotating bridge. He ran into that side closet near the front, left-hand side of the room. Use Gooigi to slip through the pipes and shoot Toad over the wall with he Poltergust! Remember Luigi, Toad is a useful guy to have around. You can shoot him at objects with red and white stripes, like ladders or shelves, and he'll help you out. Do that if you ever get stuck down there in the sewer.

Good, you got him? Get back up here. What's that? The door is blocked by a ghost? Darn. Try making your way through the waterway, just like you did a few hours ago. There should be another exit. Just be careful, ghosts will come for you! Use Toad!

Look, there's the missing part to the Poltergust I mentioned, use Toad to shoot down the ladder near the closet, go up it, and then shoot down the part with Toad again. Then head right back into the sewers. They should be drained now so you can jus roll on through, fighting any ghosts you see along the way. Head to that last room and then through the passage way on the left. Now it's time to get back to conquering this hotel!

Take a Ride on the High Seas (12F)

The Spectral Catch name is an authentic 1670s experience where it actually feels like you're on Tortuga, enjoying a great night out. Grab a drink, take a walk, and enjoy the moonlight on our to-scale model of an actual pirate ship in our lake-sized tank on the 12th floor.

Luigi! Use the attachment I just gave you to blow through that ship. Walk up to that special plug and press X! Then head through the bar to the area with the lake, I have a feeling something will be waiting for us on that ship. Once you're in the outdoor area head to the dock.

Luigi! This shark is no joke, he'll bend the floor boards to attack you, grab and shoot shoot the bombs at his mouth to hurt him. Once he's back on the desk as a shark, wait until he attacks downward with his hook! Dodge it and then capture him in your vacuum!

Be careful! This is a tough battle. He'll take control of the whole ship and force you to use your plunger on the small target to stay hanging while he tips the ship over. Once he's done shoot as many bombs that are rolling by into his mouth. He'll get knocked out once you send three into his mouth. Then he'll pop out and attack you directly. Wait until he attacks downward with his hook, it'll get stuck in the ground so you can stun and capture him. 

Oh my! A Toad, get him with the Dark Light and bring him back Luigi!

Fitness Center (13F)

Our state of the art fitness center includes an Olympic swimming pool, an extensive amount of training equipment, a fully functional weight room and much, much more. You may even get a sneak peak of Johnny Deepend training for his next otherworldly competition.

 Alright Luigi, it's just a fitness center. What's worse is that we could run into? Head past the lobby and into the locker rooms, careful of any ghosts you might encounter. Use your dark light to reveal a bell on the lobby desk, ring it and some ghosts should appear! Defeat them to grab a key for the next room.

Go directly into the weight room when you can, you'll find two powerhouse red ghosts. One lifting weights and one boxing. Lure the one that's boxing into the middle of the room, the one throwing weights will accidentally hit him with a weight, allowing you to do some damage with your Poltergust. Repeat until you can stun and capture them!

Head into the treadmill room and run on each of treadmills in order to grab a golden key and some extra gold. Then ahead into the next room and make all the yoga mats on the ground match the posters in the mirror. Use the Poltergust to roll some up and others down. Then head into the locker and turn all the showers off using the valves in the booths. Now you're ready for the pool, Luigi!

Johnny Deepend is a world class swimmer who trains for dawn til dusk every single day, only resting to load up on calories and fresh goggles. You can watch him in action all you want during your indefinite stay at The Last Resort.

Luigi, you'll need Gooigi's help a lot for this one. You'll need to distract the swimmer by shooting balls at him. While he's stunned take Gooigi through the metal barriers and to the other side. If he wakes back up switch back and shoot him with another ball. Get to the control point on the other side and drain the pool!

The swimmer will get sucked into the drain, hop down to fight him. Use your Poltergust to shoot another ball at him, stun him, and then pull his glasses off. Then you'll be able to stun and capture him. Grab that button as soon as you do!

Polter Kitty, again?

Looks like that cat got you again Luigi, after him! Do the same thing and chase him to the lobby, the beach on the 12th floor, and the stage on the 11th floor. Wait for him to attack before stunning him. Do so three times and the button is yours!

Hit the Dance Floor (14F)

If you're looking to dance your life away until the crack of every dawn, then The Last Resort's dance club is the final destination for you. Located on our 14th floor, with stunning valley views, our very own DJ Phantasmagloria spins the table deep into the night. Accompanied by our unique dance troupe, you can't find a better place to enjoy some tunes.

Luigi, head down the hall and up the stairs, feel free to explore the coat room and merchandise store. Head to the dance floor when you're ready!

Oh man, is that a ghost dance group? I guess they need some way to spend time around here. Look, they have the elevator button! OK, you'll need to keep an eye on whoever has the button, it looks like they toss it around. Wait until they break off from their group and use the vacuum jump to knock the one with the button. Do that a few times and capture each ghost as you knock their wardrobe off.

Then it's time for DJ Phantasmagloria, she's pretty easy to handle Luigi. Wait until she is juggling her records, use your vacuum jump to get her wig to pop off, then stun and capture her! Do that a few times and you'll capture her.

Luigi! There are four keys you need to get in order to open that big King Boo statue up. Let's get out of this first room, use Gooigi to squeeze through that pipe on the right, climb up the ladder and grab that rope. Walk off the ledge with it to fully extend it! Ok, we're through.

There is a puzzle in each room that you'll need to solve. Head to the first room on the left hand side. It's a library, walk carefully through and dodge all the lasers. Get all the way down the stairs. Shoot the power box with your plunger and pull the rope! This should deactivate the lasers and let you grab the key up top.

Now to the first room on the right, use your dark light to activate the door and head inside the room. There will be a few sofas and a painting. Spin the windmills on the painting to make part of the floor move to reveal different secret compartments. Be careful though, use the vacuum jump to kick powder up in the air and reveal the lasers. Move Luigi in front of the moving compartment while you move the windmill with Gooigi until a power box comes up, then use Luigi's plunger to pull on it. The lasers should fall so you can grab the key that was protected in another compartment. 

Head over to the master bedroom, walk over to the first mannequin and pull it with your plunger, do the same to the other mannequin too. The floor will flip over revealing a large scale, be careful walking to much on one side will make you fall. Balance walking back and forth between the two sides to make it go up slowly. Do so until you reach the power switch to turn the lasers off! Do so and then grab the key!

Lastly, head to the bathroom! Time your jumps by walking out in the path of the laser when it's far away and jump with your vacuum when it gets close. Keep heading down the pathway and dodging lasers until you can turn the power off and make it safe. Then head into the tub and turn the water on with the Poltergust. That will reveal the final key.

Now go out there, fight some ghosts, and open that door!

OK Luigi, this is a big fight. Use Gooigi to slip underground and move through the different barriers, he can turn the lasers she has on. Dodge the spinning one until it goes away, then have Gooigi use his plunger to shut off the different color lasers. Once you do that, wait for her to try and strike you. She'll hit the ground and that's when you stun and capture her. Do it a few times and you should be clear.

Look it's Mario, free him and then follow him to the roof!

Welcome back, Luigi

And now it's time for the final  battle with an angry King Boo. Take breath and get ready to fight. 

(Image credit: Nintendo)

To take King Boo down you'll have to dodge his tongue, slam, and fireball attacks. When he shoots out a spiking ball full of bombs grab one that isn't about the explode fire it into Boo's mouth! Wow! Use Luigi's and Gooigi's Poltergust to slam Boo back and forth.

When Boo is duplicating you'll have to do the same thing but dodge more attacks. The real King Boo has teeth, so Luigi will need to aim for that one with the bomb. Same when Boo triples himself. Keep going and it'll all be over soon.

It looks like it's all over now, the The Last Resort is in shambles but everyone is ok. Let's go home.
