A lot of the issues with declaring something “fluffy enough” is that people tend to work on a binary. Something either is fluffy or isn’t.
I suggested this before, but what we need might be a trait list of sorts. Fluffies have a lot of fluffy-esque traits, and that’s what we tend to judge subspecies and OCs and such by even if we don’t realize it. There is an acceptable amount of fluffy that people are subconsciously aware of.
Things like looking pony-like, having thick fur, short limbs, hooves, and a child-like demeanor, using flufftalk, being innocent and naive, stupid as hell and quadrupedal, loving spaghetti, appearing in all colors, shitting a lot, loving babies, being fragile as all hell, being afraid of water, herd dynamics, being mainly herbivores, and so on.
Not all artists use all of these traits. I don’t use the shitting-a-lot or ultra-fragility traits, some artists don’t do the innocent and naive (aka draw exclusively hellgremlins) or have them be less stupid, some people don’t have the short limbs so the fluffies are more actual-horse shaped. But they all still register as fluffies.
Subspecies and OCs need to keep enough of these traits to have a passing grade in fluffy. For example:
- Kitsunefluffs are just fluffies with fox tails (that they love a lot) who don’t love spaghetti.
- Sea fluffies are just fluffies with fins instead of legs (that live underwater).
- Fluffaloes are just size XL fluffies with buffalo horns.
- Micro fluffies are just size XS fluffies.
- Cannibal fluffies are, in a vacuum, just fluffies that eat meat (and have swirly eyes). More on them below.
That said, the personality of the fluffies is very important. That child-like ideology and love for all. If that’s changed, well… I think there’s a reason why people considered hellgremlins to be a separate thing and caused a bunch of wars about it, and that’s because of this. They still read like fluffies, but like a subspecies. “Fluffies but they’re naturally assholes who torture each other for fun.”
Cannibal fluffies specifically run afoul of this a lot. “Fluffy that is carnivorous” is in itself fine, but a lot of cannibal fluffies are also sadistic and smarter and stronger than a fluffy. That changes too many traits, and the result stops reading as a fluffy, causing people to cry foul. It’s a super-smart asshole carnivorous fluffy.
OCs run into this, too. Here’s a herd that behaves more like a Warrior Cats clan than a herd, here’s a human OC that I transplanted into a fluffy body and changed nothing else about, here’s a fluffy that killed her owner with a knife and now hunts for abusers to kill off vigilante style. It removes the childishness and stupidity and herd dynamics and fragility, so too much changes and people cry foul.
For example, sea fluffies are okay and so are cannibal fluffies (in theory). Combine them to make a shark fluffy, which is a sea fluffy but it’s faster and more durable (to catch its prey) and it has fangs and eats other sea fluffies … and I bet some of you just cringed a bit.
Note also, jellens aren’t fluffies. Puffy griffins aren’t fluffies. My Wish Granter creature isn’t a fluffy. So having non-fluffy creatures is fine, HOWEVER, they need to be treated with a lot of extra care and should not be a main character, by virtue of not being fluffies.
Jellens came from hilariously badly drawn foals. Puffy griffins came from the griffins in the MLP show (but evil? for some reason?), and Wish Granter is like a fluffy horror version of Discord from the MLP show. So they’re based on pre-existing ties, and any new creature that doesn’t have such a tie will get some big side glances.
And note, a story that focuses on any of these as a main character will fall flat right away. Because they’re not fluffies. They’re just … other creatures that happen to share a universe.
So yeah that’s my suggestion. A checklist or chart that says “if it’s not at least X% fluffy, people are gonna call foul”. Like one of those Mary Sue tests, maybe! That’d make it fun.
