In Alola, Grimer has a dual-type Poison/Dark regional form, Alolan Grimer. It evolves into Alolan Muk starting at level 38. These Grimer can also be found in Blueberry Academy's Terarium.
Grimer is a slimy, amorphous pokémon, born from sludge in dirty streams or seabeds that are exposed to 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. Should it run out of internal germs, Grimer will die. 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, which is Grimer's main diet. It can be found in polluted lakes and streams, as well as within cities and factories where trash and industrial waste can be found. In recent years, thanks to efforts in environmental improvements and a decrease in their food source of waste, Grimer is now facing extinction.
Prior to Generation IV, Grimer and its evolved form, Muk, were the only known pokémon that could have Stench as an Ability.
