"A flying squirrel gliding between trees": It won't be able to do it. Just telling it "flying squirrel" will often generate squirrels with bat wings coming off their backs.
Ahh, but that's just a tiny, specific thing missing from the data set! Surely that'll get fixed eventually as they add more training data...
"A fox girl hugging a bunny girl hugging a cat girl": The only way to make this work is with fancy stuff like Segment Anything (SAM) working with Stable Diffusion. Alternative prompts of the same thing:
"A fox girl and a bunny girl and a cat girl all hugging each other"
It's such a simple thing; generative AI can make three people hugging each other no problem. However, trying to get it to generate three different types of people in the same scene is really, really hard and largely dependent on luck.
The flying squirrel one, was spot on, it showed an image of the trees, and a squirrel with wings, which kind of looned like bat wings.
The 3 girls hugging each other however worked fairly well, it always created 3 different types of persons, but they never hugged each other. Either two of these 3 hugged each other, or no one hugged someone.
Would be a lot easier if AfterDetailer could handle dynamic prompts.
