Grimer

Grimer is a slimy, amorphous blob-like Pokémon, made of living purple sludge. Its body is a pungent cesspool of bacteria, which are so potent that it renders soil barren and incapable of supporting plant life ever again. It has two large eyes with beady little pupils, and a gaping mouth with a grey tongue. While it lacks any visible legs, it does have two arms with three digits on each hand. It is constantly oozing; endlessly leaking a germ-infected fluid from all parts of its body. Pieces of it often breaks off during travel, and from these pieces new Grimer will begin to grow. When combined with another Grimer, it produces new poisonous compounds.
