Grimer is a Poison-type Pokémon.

Biology
Grimer is a slimy, amorphous Pokémon whose body was animated because of lunar radiation. It has two large eyes with beady pupils and a gaping mouth with a gray tongue. While it lacks any visible legs, it does have two arms with three digits on each hand. Its purple sludge body contains a variety of pungent bacteria, which are so potent that it renders soil barren and incapable of supporting plant life. It is constantly oozing a bacteria-rich fluid from all parts of its body. Pieces of it often break off during travel and go on to become new Grimer. When combined with another Grimer, it produces new poisonous compounds.

Due to its lack of a solid form, Grimer is capable of squeezing into any space or crevices with relative ease. It uses this to penetrate sewage pipes and feed off of the filthy wastewater inside. Its population fluctuates based on the availability of waste. It can be found in polluted lakes and streams, as well as within cities and factories where trash and industrial waste can be found.
