The Ever Grey Swamp (also known as Always Grey Swamp or sometimes spelled with “Gray”) is the hideout of Eva and her gang ever since she attempted to steal the Friendship Heart. Many of its inhabitants include Krakia and Durillia.
The swamp is the eeriest and most disturbing place in all of the Pocket Kingdom. Very few pets are said to set paw in the swamp, as many are too scared to do so. In some areas, there is quicksand that, oddly enough, can leave you glued to it rather than slowly sinking in like in real life. Many of the herbs, flowers, and vegetables grown in the swamp can leave anyone who consumes or inhales their pollen with afflictions such as a stomachache or knocking them unconscious.
