Water blue is the lowest growth of monsters in mushrooms. In addition, you don't have to worry about mushrooms, pure white, melody, aegis and mouse king if you need 300 spiritual pets. Among nostalgic mushrooms, the most cost-effective one is green mushrooms. Recently, the new 1 grade mushroom is good and beautiful, but the price is very expensive. In addition, I recommend changing swamp trees and dragons, which have the same ability as pink mushrooms.
