Stone Flowers are used by Zalleo. If Zalleo eats "Over 9000!" Stone Flowers, Zalleo will become Toon Zalleo. If another being touches a stone flower, they will likely turn into stone, or become very dazed and stupid. Certain beings can have a "stone" form, which is a stone statue that is very strong, but restricts their movement a hundred fold.
Stone flowers are made by adding rocks and a certain plant ingredient to a base flower. The stone has no energy, but it makes the flower very hard. The plant adds the energy, which causes the flower's effects.
