Grimer may be distantly related to Koffing (since both Pokémon are associated with pollution, and whose evolutionary lines are the only ones to learn Sludge). Grimer emits an odor so strong and disgusting, many cities in the Pokémon world have been evacuated because of its presence. Since Grimer's body lacks a solid form, it can slip through the smallest of openings. Grimer thrive anywhere there is pollution and even feed on it. As it moves, it loses bits of its body from which new Grimer emerge, which worsens the stench around it. Grimer also exudes a germ-infested liquid from its body that acts as a herbicide and makes the land around it uninhabitable for any new plants. Not even weeds will grow in the path of a Grimer.
