Playing with some ideas mostly regarding gender/reproduction in RW, and slugcat colonies.
Full transcript under the cut!
Creatures in Rain World are typically simultaneous hermaphrodites but require partners to reproduce, with either individual capable of being a genetic donor or carrier. Alongside what we are familiar with, this has lead to interesting reproductive strategies such as rotating donor/carrier roles, or dual/simultaneous genetic swaps.
Rotating donor/carrier roles - A K-selection reproductive strategy. One partner carries the first child, the other partner carries the next child, and so forth. Allows each partner to recover from the demands of childbearing.
Rain Deer aren't quite monogamous, but they tend to choose the same breeding partner whenever mating season rolls around. They serve as a donor one season, then bear and raise a child the next. Calves are raised away from the rain and worm grass, in places that have less food but more safety. Calf wool is softer, not yet gunked up by the dirty rainfall. Their legs are sturdier as children, allowing them to run for cover while the parent wards off threats.
Dual/simultaneous genetic swap - An r-selection reproductive strategy. Parents fulfill the donor and carrier role for each other. The more children you make, the more likely some are to survive!
Multiple batflies lay thousands of eggs in a single "blue fruit." Several eggs congeal and become nutrient paste for the surviving eggs (and for hungry slugcats). Like some plant seeds, batfly eggs that are consumed before pupating can survive passing through the digestive system. Ew.
Ancients also fell under this umbrella. Their genders (and the genders of iterators by extension, who have no sex anyways) could have been determined by a variety of other factors, such as societal role, donor/carrier preference, or simply different categorizations of personal expression.
It's difficult to say how well their common pronouns would translate to ours, but it seems they can translate to an extent, given what Moon and Pebbles use canonically.
Slugcats, like real slugs, can have children with a partner or self-fertilize. Unlike real slugs, they are often known to adopt.
In the case of self-fertilization: children who are born from one parent may display a large amount of genetic diversity despite the circumstances. Maybe slugcats have some sort of... genetic reservoir independent of their own genetic code?
Slugcats live 20-30 years on average... if they manage to reach adulthood. Their mortality rate is sadly rather high, especially in pups. If they were to develop as a civilization, it's likely their lifespan would increase dramatically.
Slugcats in a colony are more likely to have more children, and to successfully rear those children to adulthood, than those who wander alone or in small groups. The safety and stability of a colony cannot be understated.
Colonies either have a set, cycling migration path, or wander continuously. Survivor and Monk's tree home was a nesting site that their colony frequents about once a year. So it's likely that they'll see their family again!
...also, the strength of large colonies are why scavengers are likely to become the dominant species. In the time of Saint's era, continuous migration has become more of a risk, and it has become more difficult to support large populations. Slugcat populations have shrunk back to the more forgiving equatorial zones.
Saint's tongue is pretty unusual and probably unique to them, or to a small population that they hail from. Fur (of varying thickness) is much more common.
Meanwhile, scavengers are bulkier and covered in thicker insulating fur. They:
have seemingly massive populations
have a burgeoning society (the existence of merchants, tolls, bartering, elites and leaders)
are adept at communicating (non-verbally)
manipulate their environment
can build structures (scavenger-made structures were a scrapped idea from Saint's campaign)
can create complex weapons and tools
may have agriculture behind the scenes (unsure if scout parties prioritize exploration or hunting)
I would wager on scavengers developing more quickly than slugcats, but it would be nice if there was a future where both could co-exist.

okay, i think any time anyone asks what superpower we’d like to have most everyone on this website would say shapeshifting but what kind of shapeshifting would you like
type 1- wild shape, you can turn into any animal, real or fictional
type 2- mystique, you can turn into any real person
type 3- cosplay, you can turn into any humanoid fictional character
type 4- jake the dog, you’re super stretchy
type 5- character creator, you can alter your own appearance- like changing voice hair length texture color, changing height and weight, transing gender, etc, but you can’t add anything non-human (ie horns, wings, claws, etc)
type 6- additional features, you can add things like snake eyes, horns, cat ears, tail, claws, wings, mermaid tail, but you remain humanoid overall and can’t change things like height or gender presentation or hair color. you can still change your voice tho
type 7- were-wolf, we all know what a werewolf is, lads. can be any kind of animal. can be straight up wolf or more monstrous wolf form that’s up to you.
type 8- furry, you just become your fursona. or any kind of fursona really you can change between them
type 9- antman, can become small or big
type 10- other, say what kind ya want

My favorite new Halsin kiss is the one where Tav has to get on their toes because he just REFUSES to bend down this time. A man just a little ashamed of his size. Never uses it to intimidate, never uses it to coerce. Gentle man who always tries to be smaller than he is. Speaking softly, carving little ducks. He stops and grins to himself as his partner has to stretch to meet him. Eagerly stretches, even. He gets the tiniest THRILL of just allowing himself, for once, to tower over his partner, and his partner loving that about him.

"For the first time, genetically modified pig kidneys provided “life-sustaining kidney function” during the course of a planned seven-day clinical study—a first step in addressing the critical crisis worldwide of kidney donor organ shortage.
The University of Alabama’s pre-clinical human study at Birmingham also advances the science and promise of xenotransplantation as a therapy to potentially cure end-stage kidney disease—just as a human-to-human transplants can.
“It has been truly extraordinary to see the first-ever preclinical demonstration that appropriately modified pig kidneys can provide normal, life-sustaining kidney function in a human safely and be achieved using a standard immunosuppression regimen,” said UAB transplant surgeon scientist Jayme Locke, M.D., director of UAB’s Comprehensive Transplant Institute and lead author of the paper...
The peer-reviewed findings published last month in JAMA Surgery describes the pioneering pre-clinical human research performed on a recipient experiencing brain death...
The pre-clinical human brain death model developed at UAB can evaluate the safety and feasibility of pig-to-human kidney xenografts, or transplants, without risk to a living human. It is named for transplant pioneer Jim Parsons, an organ donor whose family generously donated his body to advance xenotransplant kidney research, like the latest patient did.
A Critical Need
Kidney disease kills more people each year than breast or prostate cancer, while more than 90,000 people are on the transplant waiting list. More than 800,000 Americans are living with kidney failure and 240 Americans on dialysis die every day. The wait for a deceased donor kidney can be as long as five to 10 years, and almost 5,000 people per year die waiting for a kidney transplant.
Groundbreaking Study Details
The 52-year-old study subject for this research lived with hypertension and stage 2 chronic kidney disease, which affects more than one in seven U.S. adults, or an estimated 37 million Americans. As part of this study, the subject had both of his native kidneys removed and dialysis stopped, followed by a crossmatch-compatible xenotransplant with two 10 gene-edited pig kidneys, or UKidney.
The transplanted pig kidneys made urine within four minutes of re-perfusion and produced more than 37 liters of urine in the first 24 hours. The pig kidneys continued to function as they would in a living human for the entirety of the seven-day study. Also, the kidneys were still viable at the time the study was concluded.
“In the first 24 hours these kidneys made over 37 liters of urine,” said Dr. Locke. “It was really a remarkable thing to see.” ...
Gene editing in pigs to reduce immune rejection has made organ transplants from pigs to humans possible. The natural lifespan of a pig is 30 years, they are easily bred, and they have organs of similar size to humans. Genetically modified pig kidneys have been extensively tested in non-human primates, and the addition of UAB’s preclinical human research model—the Parsons Model—now provides important information about the safety and efficacy of kidneys in human transplant recipients."
