The dharma set in the Animal Crossing series consists of three furniture items. They are each red, egg-shaped wishing dolls known as Daruma in Japanese folklore. When making a wish, the owner of the doll colors in the first eye, usually the right. If the wish has been fulfilled, they then color in the other eye.
All dharma have a completely red Feng Shui. Placing them on the east side of a room will bring good luck.
