When Luigi first enters the Back access before the boss battle, he won't be able to enter the Pool since it's blocked by a bunch of towels. The is a treasure chest near the bench that Luigi can use the Dark-Light Device to reveal and obtain Bills and Coins. There's also a trash can near the stairs filled with gold bars, bills, and coins by using the Dark-Light Device.
