Though not commonly visited, this room contains 90 rupees in total and can be useful if extra money is needed, e.g. for an upcoming trip to Zora or Palace of Darkness.

Note that like the rupees in the Houlihan Room and Palace of Darkness basement, collecting at least one of these rupees will set a flag that will cause ALL of them to disappear permanently. This happens as soon as you leave the supertile that this room is in -- in other words, after transitioning more than one room away. This persists in your save data, so farming this rupee room multiple times is not possible.
