Floor 725
In this floor, there are lengthy tables laid out with all kinds of tea, in all kinds of mugs, cups, and glass. You need to guess the kind of each tea you come across in order to progress.
This floor have some souvenirs from Floor 730. The reason the souvenirs are right there is because Floor 730 doesn't have much room for all of the souvenirs.
This floor is where everything lost ends up. Enjoy sifting through the mountain of items trying to find what you've lost because it's going to take a while.
Floor 739
This floor is a display of all the colors you're able to see. All their names are listed as well, it's a huge floor. Nothing exceptional you have to do here, just pretty stuff.
