In spite of drawing maskoon first I struggled the most with this line, and I think it probably shows. Oh well.

Maskoon, the raccoon pokemon
Maskoon is a small water-type pokemon known for its mischievous nature and adaptability. They frequently raid garbages, gardens, and campsites for all kinds of tasty treats - chips and fruit are some of their favourites. In rural and wilder areas they tend to stay in small groups but in cities they can form large gangs and can be quite territorial. However they are still small and a loud noise, bright light, or a thrown boot will cause them to scatter. Maskoon will often bring treats to share with their trainer, but in practice this means having to find the treat's original owner and apologize, more often than not. Maskoon evolves into Racclean at level 17.

Racclean, the raccoon pokemon
Racclean is a medium-sized water-type pokemon from the Ronto region. They are more solitary than maskoon and also spend more time near water, playing in streams and splashing in puddles. When they find food they bring it to their favourite water source to wash it off before eating it, although some human-made foods like puffed corn or cotton candy dissolve in water - a tragic lesson every racclean eventually learns. They often hunt for food in dumpsters, landfills, and other unsanitary areas, but they clean themselves and their food fastidiously after scavenging so they rarely get sick. Racclean evolves into Janitorrent at level 38.

Janitorrent, the wash-bear pokemon
Janitorrent is a large water and poison-type pokemon from the Ronto region. These pokemon can sequester toxins from their environment in their fur so that anything that tries to eat them gets mouthful of the most sour, spoiled taste it ever encountered, and spits them back out. Janitorrent likes a clean space to live in, and it mops up anything dirty or hazardous it encounters with its tail. Once its nest and food is completely clean, it can relax and enjoy the treats it found while scavenging. Many building owners in Rontonian cities employ cleaning staff with janitorrent pokemon to keep their buildings spotless, but nowhere are they more valued than hospitals. Their keen sense of smell can immediately tell a clean room from a contaminated one, so that germs aren't passed on between patients and staff and visitors.
