https://www.furaffinity.net/view/36732635/ Man to woman, to Gorgon which is like multiple partial snake TFs. Also oviposition but that's not relevant.
https://www.furaffinity.net/view/36369715/ Women to snake and vores a man. Or I guess woman turning back to snake since its implied she was born a snake and the human was just a guise
https://www.furaffinity.net/view/35890367/ or here is a specific one- Woman to Seething Bazelguise from Monster Hunter.
https://www.furaffinity.net/view/34666086/ Well.. its half fish. Mermaid TF and BE n Hairgrowth. Don't worry, legs definitely do not fuse.
https://www.furaffinity.net/view/35372956/ Anthro mink changes a woman to have some cat features, reverts, then half frog features, reverts, then turns her completely into a mouse, does some tribbing to earn her humanity back.
Male TF seems a bit frowned on so I link these with a Warning;
https://www.furaffinity.net/view/32924581/ man to mouse with some minor AR
https://www.furaffinity.net/view/35290750/ This one is multiple people to different things, the first TF is Woman to rabbit, BUT, it overlaps the start of a man to stag TF, and the remainder is two men to stags.
Now I know its close to horse/donkey/zebra, but I think giraffe are underrated;

I have lots of oddball TFs too, like man or woman turning into a hybrid of 12+ different animals, an entire series based on a man turning into various mythical beasts to make love to mythic demi humans. A story about a demon incarnated as a living dress, a woman turning into a camel/dragon hybrid, a man turning into a ram/wolf hybrid, man into an alien horse, woman into a unique species I call a Pinlion and has sex with a hermaphrodite centaur, etc. I like variety. But I generally avoid things really far off like insects, and keep reptiles to a minimum just because I don't think it would do well favourites wise. I don't generally have a big audience to begin with, so the farther out I go the bigger a risk it is at being a flop.
Hmm, I also wouldn't mind a nice slug TF- there are some elaborate looking slugs out there. Although I guess that might be kinda horrifying on human scale since even garden slugs have thousands of microscopic teeth on their underside...
