There’s Money Everywhere
After spending a couple of hours with Luigi’s Mansion 3, you would probably think that our boy Luigi here is in some type of financial trouble because he loves picking up tons and tons of money with that vacuum cleaner of his.
I’m not sure if Luigi is in debt or if the Mushroom Kingdom Mafia is after him and his bro, but good lord, there is so much money to collect in Luigi’s Mansion 3 and you can literally find it in every single room in some form, whether it be gold bricks, dollar bills, gems, pearls, or gold coins.
Make sure to interact with every little thing that you can so that you can rack up your savings account though because later on in the story, you’ll need that cash for E. Gadd as he has his own shopping network for you to check out in his lab.
It’s basically just used to track down all of the secret gems and Boo’s in the game by purchasing trackers but if you’re not good at puzzles, the trackers will definitely come in handy at the end of the day.
