Grimer and Muk

bills-pokedex:

Grimer
The Sludge Pokémon
Type: Poison
Official Registration #: 88
Entry: Born from polluted rivers, this pokémon’s body consists entirely of highly toxic sludge. It consequently thrives on pollution, and as such, it flocks to polluted waterways, where it has been known to clog up entire sewer systems in its zeal to consume raw waste. Despite all of this, grimer populations are considered to be the most prevalent in Kanto and Hoenn, home to two of the most aggressive green campaigns in the world, despite the fact that other regions historically had difficulties with pollution, are centers of mining and manufacturing, and are currently so polluted that their environment has given birth to sentient garbage bags.

Muk
The Sludge Pokémon
Type: Poison
Official Registration #: 89
Entry: The evolved form of grimer, by battle experience. Like its preevolved form, a muk’s body also consists entirely of a highly toxic sludge. However, due to its increase in mass, power, and age with evolution, muk is able to cultivate highly powerful strains of bacteria and viruses that infest every inch of its skin. Physical contact with this pokémon can kill plants and smaller or weaker animals on contact … which should speak volumes about the resilience of pokémon researchers and their assistants as a whole, considering the fact that certain muk express affection via alarmingly frequent tackling.

Grimer (Alola form)
The Sludge Pokémon
Type: Poison/Dark
Official Registration #: 88
Entry: This sludge-like pokémon actually descends from grimer imported from Kanto. Decades ago, when Alola was facing a pollution crisis, the regional government took notice of how grimer consume waste and attempted to bring in a small but tame population to consume the considerable amounts of garbage clogging Alolan streets. Naturally, some of these grimer escaped and reproduced, and over generations, they mutated to match their comparatively less toxic food sources (that is, compared to the diets of standard grimer) … as well as the psychic and steel predators also brought in to handle the out-of-control grimer population. Long story short, this is exactly why: A) there are infestations of grimer, abra, and magnemite in certain parts of Alola, and B) coming up with good ideas should not be left to people in politics.

Muk (Alola form)
The Sludge Pokémon
Type: Poison/Dark
Official Registration #: 89
Entry: The evolved form of the Alolan variation of grimer, by battle experience. Despite its fangs and sharp spikes, this highly colorful pokémon is actually sweeter, gentler, and far less fragrant than its standard cousins. Additionally, its skin is comparatively clean, making it safe to touch. However, contrary to popular belief, it’s often a bad idea to hug one unless you’re experienced with training this variation of muk, as both its bodily fluids and its spikes are highly toxic. Naturally, considering the toxicity of certain parts of its body, combined with its vivid coloration and docile nature as well as the Alolans’ general ability to make sound decisions, most residents of Alola consider their variation of muk to be a highly popular mascot for children’s programming and products.
