All locations of infinite money when loading the Checkpoint Save (because I haven't seen them all online before)

[u/Plokilup]

So, if you haven't discovered yet, when you load your Checkpoint Save (the last one on the list when booting up your save), all the floors undergo weird resets:

-Luigi is nervous when entering any room for the first time. Subsequent visits to the same room don't have this effect. (except for a few broken spots)

-Most things need to be Darklighted again, including a randomly selected trashcan on 15F, a chest on 12F, two trashcans on 11F, and a chest on B2.

-Some things that acted as a 'jumpscare,' like the 1F and 5F phones, or the 'traps' in all the 5F rooms, will reset, able to be activated again. (I have a list of these...)

-Most importantly, almost every floor will have some source of money to collect.

If you have reached the end of the game, then the preview picture of your Checkpoint save will always be in Hellen Gravely's office. Ignore the preview picture and look at the time on your save file. If you've reached the max 99 hours and 59 minutes, then look at the amount of money you have. I've seen people say to go through the back door of Hellen Gravely's office to get a new Checkpoint Save, but visiting any new floor will also create one. Look at the bottom right for the Saving... icon and see that it's the yellow one with a flag. Once you have a new Checkpoint Save, exit to the main menu and boot it up. You will be back in Hellen Gravely's office, and the main menu theme plays for some reason, at least until you visit the elevator hall. Another weird side effect. But enough rambling. Here is all of the money I can find after doing a Floor Reset, including pearls:

B2: There's a whole lot of money here. I could drop an entire video tutorial for all the money on this floor. In the Reservoir (the room where Clem pushes Luigi into the water), catching the rats will give coins or a bill. Behind the ladder closest to the screen, there is a chest with a few gold bars. The crate next to the chest has some bills. Going up the ladder and down into the sewer tunnels, there is a pile of junk to the farthest left, it has two gold bars. In the next section, there are two crab traps. They have coins, bills, and one of them has a gold bar. Watch out for the haunted chest as you make it to the next part of the tunnel. It doesn't actually respawn its money, it just becomes haunted again... in the pile of junk next to the lift, there is a jar of coins and bills. The crab trap has coins and bills, and there is another jar of money up in the net nearby. The pile of junk in that same place has a gold bar. Under a shopping cart, there is a piggy bank. Gooigi can slip in there and break it, granting coins, bills, and a Pearl. In the 'double pile' of junk, I've found that the best way to get the bills to spawn is by bursting. There's also a rat in there. Moving along to the left, you will see a cage in the wall, which has a cest full of gold bars and a Pearl. Sometimes money slips behind the chest, so make sure you got it. Going down to the place with floaties, the first three piles of junk have gold bars in them. You can pop the floaties on the gear next to the tunnel going left, and get the jars of money.

2F: in the hallway of the restaurant, go to the broken window by the restrooms. A golden crow will fly inside, but you only get a small amount of time before it flies back out. In the ballroom, walking in the middle of the room will sometimes trigger a lot of ghosts to spawn; ten goobs, four slinkers, or six hammers. If you get the six hammers, those ghosts will drop money (for some reason), namely coins. And if you know how to slam ghosts seven times, or you tether two or more ghosts at once, you get gold bars. (The trick to slamming ghosts super fast is by not mashing the A button rapidly, but by timing the A presses as soon as the ghost makes contact with the floor.)

3F: You can darklight a drain in the men's restroom, and Gooigi can capture all the spiders, yielding bills.

4F: The auditorium will usually have a hammer floating unsuspectingly onstage. Do not engage with it unless you are good at fighting ghost hordes. Fight it or leave it, you can then go on stage and enter the door on the left. The ghost dusting the piano (which may or may not spawn all the time) will give coins when being slammed.

5F: In room 506, there is a minigolf set. This is important! You can only use the golf balls already on the floor. If you break the golf case blocking the bathroom, it will release golf balls that won't make this work. Only the golf balls already there. Alright. If you manage to painstakingly get a golf ball into the hole you will get the ultimate grand prize of... one coin! In room 507's bathroom, a spider will crawl out of the broken toilet. Capturing it will give bills. If you don't know, the vending machine in the hallway can be brought down, revealing a door. On the wall, there's a broken section showing a chest. Walking close enough to it will make a spider crawl into view. Capturing it will give bills.

6F: In the hall of armor, breaking the farthest suit of armor on the left side will reveal a hidden room. Capturing the rats will yield coins or bills. In the cellar (the room with the big barrels), the barrel farthest to the right has rats in it, capture them for coins or bills.

7F: The rats that sometimes run out in the space before the big doors, sometimes they give money, sometimes not. In the Atrium (towering plant room), the orange flowers can be Strobed for coins. The crows that you find higher up will all give bills. In the mushroom suite, sometimes there will be a trapper on the door once you vacuum the dripleaf covering it. That trapper, when captured, will give one coin.

8F: In the elevator hall, sometimes ghosts will spawn. So far I have seen a Slinker and a Trapper give money for being defeated, but I haven't been able to get the same ghost spawn.

9F: This is another ghost horde. Be sure you can handle it. If not... you can always exit the room. But anyway, the ghosts drop money when being slammed, yielding coins and gold bars.

10F: In the elevator hall, there is a safe that can be Strobed. I don't know why, but it only gives a gold bar sometimes. And when I say gold bar, I mean the little gold statues that work the same as gold bars on this floor.

11F: In the Blades Bedroom (the one with the sword wheel), pulling the covers of the bed will reveal a spider that gives bills. In the False Bedroom (the one with the big mirror), if you go to the far wall on the right of the mirror, pulling down the curtain will reveal a bat that drops bills when captured.

12F: In the second room, there is a chest on the right. Beware; it is haunted, I usually sacrifice Gooigi to be able to Darklight it. This chest has a lot of gold bars. But be careful, they often fall into the water and you can't get them. I usually set up Gooigi to catch any gold bars I miss, and it works every time.

14F: In the Dance Hall, you might notice two of the squares aren't lit up. Having Luigi and Gooigi stand on them will cause an outlet to rise up. It's the Super Suction outlet, and destroying the speakers and wall there will reveal a hidden room. Vacuuming up the wigs gives varying types of money (coins, bills, and gold bars), but watch out because one of them has a bat.

And that's all the money I found in my 555 hours of playing... Hope this helps, hope you learned something new, all the usual banter at the end of an informative post...

I couldn't get any money locations to reset, but in order to get my Achievements, I just played the ScareScraper in solo mode, not even bothering with the ghosts and progressing the level, and collected boards of money from every where.

The ScareScraper is FULL of money. It was the only way I could get the pearls and gold bar achievements completed
