Step by step guide to the main adventure

Load your proton packs, or change the filter on your vacuum cleaner, it's time to explore the Hotel Miramostri, Enjoy your stay everyone!


-Explore the lobby for fun animated scenes, then talk to the receptionist to continue. Then visit your room, even the bathroom, and when you're done interact with the bed to rest. When you wake up open the drawer to the left of the bed to find some coins and then go out and visit the other rooms in search of your companions until you reach the elevator.

-After the animated intermezzo run to the left, avoiding obstacles, and use the trapdoor on the wall to reach the laundry room.

Floor B1 - Basement

-Pursue by interacting with everything you can to get coins. Just before you leave the area you will see a green gem in a washing machine. Now you won't be able to pick it up so get out of the laundry room and enter the garage. Go to the bottom right to finally find the Poltergust G-OM inside the car. Now you can suck or repel enemies or jump to destroy the surrounding objects thanks to the Bounce. (you can also go back to the laundry room to absorb a lot of money especially from the top shelves or by turning the red crank just before the washing machines with the gem).

-Go out and continue to the right, there's a gem in the painting but you can't take it now. Use the strobe of light with the Strobobulb to open the door blocked by the device. In the next room use the Strobobulb again to activate the vending machine and get coins. Use the suction jump in front of the fire extinguisher to break it and get more coins, while in the under staircase you will also find a casket with various gold bars and banknotes. Go up the stairs to the top to find yourself in the hotel lobby (just below the end of the stairs you can see another gem that you can't take at the moment).

Floor 1 - Large Hall

-Fantasma -Fantasma: Eliminate the ghosts in the middle of the hall and then use the pumpkins in the right corner to hit and destroy the 4 billboards with Luigi's and his mates' faces (just suck and then fend off the pumpkins). In this way you will get a lot of money.

-In the left area of the hall there is a gem in a painting on the wall, while if you go up the stairs and look in the crack of the wall on the left you will see another gem. At the moment you will not be able to take them so take the key hanging behind the reception, using the jerk to get there and climb the stairs upstairs to open the central door.

Floor 2 - Mezzanine

-Follow the ghost puppy until you need a key. -Mm-hmm. Enter the door to the right of the one where the puppy disappeared to find yourself in the dressing room. Go to the area on the right and you'll see a switch on the wall in the mirror. Use the Strobe to turn it on and pop the key out of the wall.

-Get back to the previous room, defeat the two ghosts, and open the door with the key. Before opening the safe indicated by the puppy, remember to suck out all the curtains from the objects to get lots of money and open the chest in the corner. Then, open the safe to unlock the Rainbow Light, which allows you to bring certain paintings back to life.

-Liberate Professor Strambic and head back to the Garage. -Mm-hmm.

Floor B1 - Basement

-Fantasma BOSS -Welcome: Enter the garage with Stambic to trigger the fight. Avoid the suitcases that he will throw against you, then use the Stroboluce and slam him like the other ghosts. Once defeated you will get the buttons of the elevator 1 and 5.

-Help Strambic to set up his workshop so that it gives you access to various options including the Multiplayer, the Gallery (to view Gems and Ghosts) and the hotel floor map. He will also give you the Virtual Boo and a Planner to install in the elevator. Now you can also shoot with the Suction Cup Hit by pressing L and access the map menu with +.

-Go to the elevator, place the Strambic devices and when you are done exit again before going up to floor 5.

-Go back to the vending machine in the right door and use the suction cup to drop it and reveal a secret room. Here you can find some scattered money and earn more using the Rainbow on the coin painting.

Floor 5 - Spooky rooms

-Pursue to the right using the suction cup and go down the stairs. Use the Strobobulb on the dispenser and after collecting the money pull down the dispenser with the suction cup to access the floor laundry.

-Get in there, suck it all in and use the suction cup on the center washer to reveal a Golden Ghost. Defeat it like normal people to get different money.

-Go out and suck out the left curtains until you find a window crossed out by boards. Use the suction cup to clear the street, go out on the ledge and come towards the screen to turn the corner of the building. Use the Rainbow Light to make the missing brick of the ledge appear and vacuum out the bubbles to make it stable and reach a casket full of money.

To get out you'll have to fight with some mini ghosts and some ghosts who are immune to the rainbow, use the bump to make them lose their glasses and make them vulnerable.

-Go to the last remaining shop and use Luigi to vacuum one of the two flowers on the top of the scissors. Then evoke Gummiluigi and vacuum the other one continuing until the central scissors change position and open the passage.

-Go in with Gummiluigi and vacuum the two chairs on the right at the same time. Turn them so hard until 2 golden ghosts come out. Then use the rainbow next to the sink to make the safe appear and get the star key. Go out and climb the escalator to fight...

Aspire a pumpkin, and when the ghost shields himself with the pan, shoot it at him to make him fall. At this point capture him as always. When he escapes just repeat the process until his vital points are exhausted. If you run out of fruit and vegetables to throw at him, the boss himself will provide you with big fish between attacks.

-Take the button that will be stolen by a mouse. Chase him into the big hall, take a slice of cheese from the basket above the mouse's den and leave it in the middle of the room, hiding to let him out. When the mouse is intent on eating, use the strobobulb to remove it and get the button.

-Unfortunately it will be stolen again and by another rat. Go out and follow him down the hall to the arcade. Go to the lockers and prepare to fight...

-Santasm -Hiding: Like the classic ghosts but able to attack from a distance and hide. Find him by interacting with objects and furniture in the room and then eliminate him as always.

-Shoot a suction cup on the center door and vacuum the mice to get the elevator button 4.

-Get back now to Professor Strambic to find out how to spend the money collected so far in Golden Bones, FindBoo and FindGemme. And also install the new feature to capture Boo or return to the lab instantly.

Floor 4 - Concert Hall

-Air the bottles to the left and shoot them on the crates above the elevator to get bills and coins. Then continue until you get to the cork that makes waves. Avoid them with the jolt and after eliminating the person in charge interact with the left basket to find three gold rats and a wagonload of bars.

-Inspect both bathrooms for coins and ingots. Remember to also use the rainbow in the women's bathroom to make a passage to Gummiluigi appear, and also open all the sinks. Then enter the large room to face...

-Phantom BOSS Ivan Spettrinsky: Initially he will throw all the chairs in the room at you so keep moving to avoid them all. Once finished you will have to defeat the ghosts in ball gown. Use the jerk to drop their masks and the usual method to catch them.

The boss will now take possession of the piano. Keep moving to avoid being crushed 3-4 times then use the jerk to avoid the shock wave of the last attack that will open the piano revealing the boss. Hit him with the strobobulb to make him escape on stage with the whole piano. Aspire one of the bombs that will throw at you (one that is not flashing). Then aim it and throw it into the piano to overturn it. Use the suction cup in the circle engraving and slam the piano to bring out the ghost. Now hit it with the strobe and suck it in. Repeat the process about 3 times and you'll have the upper hand.

-Before going down into the arena, destroy the barrels behind the fruit stand to open the casket with the ingots.

-After the movie, go to the left door and break the armor to get money. Here you defeat the ghosts and if you want you can use the suction cup on the wall in the middle of the weapons racks to open a secret room where you can find a helmet to suck to break through the armor.

-In the next room, go down the stairs and use Gummiluigi to overcome the traps and get Luigi through. Once in the cellar, spread the ghosts and then uncork the first barrel on the left with the suction cup. Enter it and press X on the left to open a door that leads to a chest and a golden ghost. Go out and uncork the central barrel to find a key.

-Open the door and in the next one use Gummiluigi to go over the spikes and suck the rope. Go back to Luigi and pull the chain in the left corner. Once underneath use the strobobulb to activate the monster's flaming mouth, suck the torch and light it near the fire. Now you can burn the cobweb and continue.

-In the room with the elevator take turns with Luigi and Gummiluigi to go down sucking the fans on the wall. Then use the rainbow on the right arch to reveal a golden sarcophagus. Use it to reach a new room with archers. Use Gummiluigi to pass them and suck the rope over the archers' device. Once the right side is broken, go back to the left side and suck the other rope to stop the archers for good and let Luigi pass and when he reaches the casket he will get a key.

-Fantasma - Mini-Sascione:-Go back to the lift room and face the Mini Sfascioni. And then continue to the left door to reach the prisons.

If you want to go down between the spikes under Gummiluigi to open a casket with ingots. Once the bridge is lined up, go on paying attention to the tilting shutters.

-In the new room with the archers, use Gummiluigi to suck the cart on the right and place it in front of the first 3 archers. Then go to the left and, after having used the rainbow to make the chariot appear, do the same.

-Cross the entire corridor and remove the tapestries from the walls by vacuuming them. After taking off the last tapestry, shoot with the rainbow to reveal the treasure room door of Maniero Misteryo full of ingots and coins.

-Fantasma BOSS King Fright: Wait for him to point you with the spear and just before he catches you to throw you in the air hit him with the strobobulb. He'll be stunned, so use the sucker on the armour and slam him. Repeat this process 3 times.

Broken the armor will be invulnerable thanks to the shield that protects it. When it swirls towards you, run away and tire it out without getting hit. Now use the strobe to make it tangible and then aspirate it. Defeated will release the button on elevator 7.

Floor 7 - Botanical chambers

-Pursue until you pick up the button. -Mm-hmm. After the film and the appearance of the tree, climb up, aspiring to everything in your path. Aspirate the creeper to overcome the abyss and then the bush to access the next room. Aspirate the leaves on the wall to reveal the door and continue. However, ghosts will appear, stun them with the strobobulb and then suck away their flower before you eliminate them as always.

-In the next room aspirate all the petals to get ingots, coins and a golden mouse. Then vacuum the left wall and press X to continue. After the movie avoid the pineapples and once on top vacuum the bush to remove it from your path. Go into the bathroom and aspirate all the leaves then take the big vase with the suction cup, drag it and bang it against the toilet releasing a point from which to destroy the brambles that block your way.

-Stritospectrum Ghost: After unblocking the road will appear this new invisible ghost that can be seen from the mirrors. Eliminate it as always. After him a Sfascione with a face full of leaves will appear. Use the jerk to find out and then suck him from behind to eliminate him.

-Go out and continue to the next floor, using Gummiluigi to avoid the pineapples that this time will be double. Enter the new room, activate the rotary saw on the strobe and then saw everything, including furniture, plants and everything in the room. Once you have cleaned it properly from above the bed a chest will fall down, using the rainbow on the hole in the left corner of the entrance door you will find a grate for Gummiluigi and you will also find another one on the right of the exit door. Use everything to earn a lot of money. Then saw the branches in front of the exit and continue.

-As soon as the branch crushes you, use Gummiluigi to free yourself and cut it with the rotary saw. Enter the bathroom with the watermelons and remove the big one by firing a suction cup with Luigi and after having sucked the rope create Gummiluigi and fire another suction cup to remove it in two. Defeated the ghosts you can continue in the hole on the wall.

-Blow with the Poltergust to unroll the branches of the plant and reach the room with the mushrooms. Move the cart with the mushroom to the front of the room and aspirate it. Now climb on the blue branch and then on the mushroom to use the bump and climb. Continue (using Gummiluigi in the duct and taking the chest above the bed to make money) and use the other mushroom to climb. In the upper room aspirate the hammock to reveal a golden ghost. Then use the mushrooms on the side of the canopy bed to climb on it and above the bed use the rainbow to reveal a chest full of pearls and banknotes. Now suck the leaf out the door and get out.

-Breathe in the branches and vines to continue. At the top of the plant use a suction cup with Luigi on one side and a suction cup with Gummiluigi on the other to open it. Then interact with X with the leaf to the south to quickly descend below and pick up the fallen button.

-Phantom BOSS Doctor Plantagrane: Aspirate the rotary saw and hide behind the giant peanuts, attract the carnivorous plant so that it notices you and when it attacks you stand ready to shield yourself with the peanut to get it trapped.

-Pursue until you get to the closed door. -Mm-hmm. Turn on the TV in the corner with the strobe and then interact with it via X. You will end up in the initial area. Use the suction cup to open the door and obtain the key. Also remember to use a suction cup on the last painting on the right to open it and get a glove and lots of gold. The glove is used to break through the top boxes to get coins and bars.

-Use the key and continue. go straight into the door on the right and vacuum everything, destroying the figurines to make many ingots. Then vacuum the machine on the central table until the golden ghost appears. Finally, use the rainbow under the table to reveal 3 ingots.

-Suck as much as you can and get close to the monkey statue and then jerk off to receive lots of gold.

-To continue, you must necessarily return the requested object to the ghost director. To do this you must first enter each of the 4 sets and activate the corresponding TV so that you can teleport to the central room and then face the 4 sets as follows (remember to suck everything you can from each set, especially by opening the electrical boxes with the suction cup):

-SET 4-

Use the camera and activate Gummiluigi. Shoot the sucker on the box and open it. Suck it all in and take the green cap from the bottle. Deactivate the camera and go, teleporting with the TV in set 1.

Run until it shoots a big energy ball at you, at which point you blow with the Poltergust to send it back at him. Use the flash to stun him and make him stop firing the small spheres and wait for the big green sphere instead. To send it back at him you will also need the help of Gummiluigi. Now repeat the process for the last time and then quickly press A to defeat the Ghost-Godzilla. Now normally capture the remaining ghost to get the elevator button 9 from Morty. Before leaving the floor, go to the director's room and capture Morty as well to add him to your collection.

-Fantasma BOSS Polthermicia

Defeat the ghosts and then use the rainbow to find kitty's hiding place. She will escape by hiding under the bench first and then in the house on the left. Leave Gummiluigi outside and enter her new hideout. As soon as she comes out go back to Gummiluigi and flash her while she is under the bench.
  2. Wait with Luigi and prepare Gummiluigi. When the pussycat comes down wait until a second before she attacks Luigi and then use the strobe flash with Gummiluigi. Suck her to remove his first tail.
  3. Chase her into the room with the 4 TVs. Get Luigi on the forklift and use Gummiluigi to blow on the knob and get him up. Use the flash on the kitty with Luigi, she'll run away and slip into the ground. Go to the elevator to be attacked by a basket poltergeist. Blow him to the ground with the suction cup and release him from the poltergeist first by lighting him with the strobe and then by sucking the purple balls. Finally take the elevator and get rid of the ghosts inside it and then go down to the Botanical Chambers, floor 7.
  4. Reach the central area and eliminate the mini ghosts just outside the hive. Use the rainbow on the plant and follow the Poltermicia's footprints. Enter the room on the first floor and inhale the ivy in the left corner to reveal the closet. Open it to let the pussycat escape and hide in a bright flower. Open them all with the flash and suck them all up until the kitty is back in the closet. Before opening it with Luigi, place Gummiluigi outside and as soon as the kitten comes out flash her with Gummiluigi. Repeat now the procedure of point 2 to rip off another tail.
  5. Follow the Poltermicia in the bathroom, blow the petals away until it escapes from the window. Now go upstairs and enter the bathroom from the bedroom. You will be attacked by the Tongue-tied Ghost. To defeat him use Gummiluigi and the flash to free Luigi. Then suck one of his tongues with Gummiluigi and one with Luigi at the same time.
  6. Enter the bathroom and use the rainbow in front of the cup to reveal a grate for Gummiluigi. Bring down your clone and on the wall at the bottom right, always use the rainbow to rebuild the tubes. Now go back to Luigi and blow the knobs of the tub to fill it with water. Call Gummiluigi back and together with him break the big watermelon. The Poltermicia will find herself splashing around in the water. Use the strobobulb to enter the nth phase of the fight already described in point 2. Suck his last tail to get the elevator 9 button.

Floor 9 - Museum of Unnatural History

-Pursue to the big red tent and open it by sucking the ropes together with Gummiluigi.

-Fantasma BOSS Troglospectrum and the Tyrannosaurus: Get to the big Tyrannosaurus skeleton to start the fight. Aspirate one of the two eggs and shoot it at the tyrannosaurus that will chew it. While it is chewing, run immediately to the other egg to shoot it in its bright weak spot on the chest. Now you'll have to repeat this process but instead of the first egg just leave Gummiluigi in front of the dinosaur who will stick to chew it like a piece of gum. Finally the tyrannosaurus will detach from its support. Stay away from him and vacuum the various bones around the area by shooting them on his chest (hit him from the sides).

Once hit 3 times it will crumble and you'll have to face the ghost inside. Wait for it to load the attack and when it hits the bone on the ground dodge and avoid the shock wave with a jolt (or take it in full with Luigi and then summon Gummiluigi while the first is stunned). Use the ghost flash while trying to remove the bone from the ground and aspirate. Now release the Toad to receive the elevator button B2.

-Before leaving the floor use Toad or the scattered bones to break all the windows and get pearls and coins.

Floor B2 - Boiler rooms

-When you get there, use the duct on the left, use the rainbow to near the right shelf to make a ladder appear and go behind the elevator to get money and coins, a casket with ingots and golden mice respectively.

-Breathe in the white wall near the first duct to Gummiluigi in order to reveal the right duct to reach the key.

-In the next room eliminate the ghosts then place all three hands of the knobs on the far right and bring Gummiluigi down the duct. Go on as long as you can then go back to Luigi and position the knob hand on the right to the left. Go forward again as long as you can with Gummiluigi and then return to Luigi and position the central knob hand to the left. Now you just have to move forward again with Gummiluigi and with Luigi move the left hand to the left to turn off the last water jet and reach the switch with Gummiluigi.

-In the circular room use the revolving bridge by operating the machine with suction/blowing. Use Gummiluigi to reach the casket on the right and then Luigi to climb the yellow staircase. After the film enter the door and continue. Go down the stairs, climb up the inflatable duck and move around blowing. Reach the duct to Gummiluigi and go down with X. Pass your green clone through the various ducts and at the bottom aspirate the ball to open the passage. Return to Luigi and continue with the inflatable duck.

-Turn the knob at the bottom to block the water and then continue with Gummiluigi and open the passage again. Continue alternating between Luigi and Gummiluigi to pass through the various areas, making haste with Gummiluigi before the duck holes up.

-Defeat the ghosts and set the 2 valves on the background with light on the right (for the one on the left) and the opposite for the other. Then use Gummiluigi and let it enter the left tube. Now with the green clone set the light of the valve upwards while with Luigi move the right valve to make the right light illuminate. then re-enter the tube with Gummiluigi to go back to the beginning and then enter again to reach the top button. Use the suction cup on the button and once the water has drained you can finally continue.

-Go back to the left to revisit the flooded areas and find more gold. You will also find a possessed chest. To defeat it, make it eat Gummiluigi and light it with a rainbow. At the end, go up and go back to the room where the ghost technician had blocked you. Open the door to the last vault and prepare for battle.

-Fantasma BOSS Brugolo: To defeat him you will have to avoid his attacks being careful not to crash into the thorny walls otherwise you will have to swell a duck and go back into the water. Avoiding its attacks with the fan (or by blowing up a bomb near it) the ghost duck will start spinning and you can suck its inflatable duck and then shoot it against the spikes around the area. Once this is done run to the ladder, press X to go out and flashare and suck the ghost. Repeated this process about three times you will defeat him.

-The problem is that the button on lift 10 will end up in the water but you only need to pull the red button with the suction cup to get it down. To exit follow the map, the exit is not very visible but you just need to come to the wall of the screen to see it.

Floor 10 - Egyptian Rooms

-Go right and suck the carpets off the walls to make money. Suck the sand out of the door and come in. There will be a very big room full of sand, if you don't want to suck it follow the next steps:

  • There are 2 Gems buried in the area.
  • If you suck out the first pile on the left, you'll find a treasure chest.
  • By using the sucker to uncork all the sand shovels on the walls you will get different money and you will find golden bats in the one at the bottom left.
  • On the right, near the initial wall you will find a magic lamp. Suck it in until its genius, a golden ghost, comes out.
  • Pay attention to the small island on the right because there is hidden a Sfascione and many mini-fantasma, as well as another casket.
  • The beach ball Boo must be shot at the tip of the pyramid to get golden bats.
  • Finally you will also find several visible amphorae to break with coins and pearls.

-To continue, climb the stairs of the pyramid and examine the statue on the left. Enter and examine the sarcophagus. Once you have fallen, aspirate to the left and examine the statue. Come out of the crack on the wall blowing sand to reach it. Use Gummiluigi to pass the arrows and block them by sucking the rope. Once you have climbed the stairs, enter the sarcophagus to reach the first room where you fell.

-In the new room open all the sarcophaguses that can be opened with the suction cup and use the rainbow on the left pedestal to reconstruct the statue of the cat and get several ingots... To defeat the mummies you'll have to make a jolt and throw them to the ground, then suck them to rub them. Pay attention to where you put your feet because you could operate the Boo balls that will take away 30 life points.

-Get into the room on the right and eliminate the snakes. Blow the sand towards the statue and reach it to activate the laser trap. Quickly blow the sand towards the pedestals with the lasers and when you are close, use the jerk to turn them off before the ceiling collapses on your head. Once the purple ghost has also been eliminated, examine the statue to restore the purple stone snake.

-Get in the room on the left and you'll have to face the riddle of the scales. To get the crocodile weight, put one of the 4 golden sphinxes on the scale, a bit of sand (blowing it) and yourself. A mechanism will be triggered and the barbed ceiling will slowly descend on your head. Put only yourself and very little sand on the scale to reach the second weight. Now you have to load the scale to the maximum. Put all 4 golden sphinxes to overcome the riddle and activate the statue that will restore the blue stone snake.

-Get in the middle room to face the poison trap. -Mm-hmm. You'll simply have to insert the shapes of the elevator quickly.

Floor 11 - Illusory rooms

-Suck the wall on the left and use the rainbow to reveal a door (if you shoot the dice and make 6 you will get several bills). In the next room if you suck and then blow (procedure to be repeated about 3 times) the saw on the box, it will open in half and reveal 2 golden ghosts.

-In the corridor with the paintings, suck the ball to the right and pull to get a pearl. Suck the painting into the central painting to reveal a stack of coins to be shown with the rainbow. Interact with the red device in the corner to obtain ingots and banknotes. Finally, pull the other ball across the hall to reveal a safe.

-After the ghosts have reversed your gravity. Use the strobe on the clock on the left and then quickly use Gummiluigi with the rainbow to make a door appear behind the bed. Enter, defeat the possessed chest (if you operate the toilet before interacting with the chest you can get a fish to shoot in its mouth to stun it) and get the key.

-In the next room, open the panel next to the dispenser with the suction cup and then use Gummiluigi to move quickly between the display cases and collect the ingots. Rotate the central table and once you have aligned the lights in the same place use the left jerk and go on stage. Stand in the middle of the lights and 2 golden ghosts will appear after bowing. Take the suction cup down and enter the new room.

-Send Gummiluigi in the grate on the floor and then go back to Luigi and suck the left wall. Use the rainbow to reveal a door and then go back to Gummiluigi to suck the balls. Interact with the key then suck the rabbit and with your clone hit it with the rainbow to get a key.

-In the room with the bed hanging, vacuum the curtains in front of the mirror to reveal a door. Continue through the next doors until you reach the three ghosts. Now the rooms will no longer lead directly to the next. You will have to pass several rooms and many fights before you can return to the magicians:

-Fantasma BOSS Magic, Amalia and Divine: You will have to wait for the three hats to approach you with the red border. At that moment jerk and then suck the rope that comes out of a hat to pull one of the sorceresses out of her top hat and defeat her as always. Things will get harder and harder shift after shift. That's why it is important that you always keep an eye on the right hat so that you don't pull the bomb out and have to start again. The last round is the most complex because there will only be one ghost and two bombs. Always follow the hat with the ghost and when the lights go out try to keep the right hat under control by jumping to avoid the cards. Defeat, you will get the elevator button 12.
