There are not too many items in this Animal Crossing room design, and even the display is messy, just applying Magma-cavern Wall and Mossy-garden Flooring, then added some ACNH items from nature like Birdcage and Hamster Cage. Of course, you can put other types of items to make it more real, like a potted plant, and design a different layout. A wide diversity of items are available to select at akrpg.com, as well as cheap ACNH bells for sale.
