You know, and I don't know why, but I picture a fleshwarped catfolk turning into a feral, serpentine thing with saber-teeth.
Other ideas for fleshwarps:
Kobolds- Mini-linnorm monsters
Bugbears- ogre sized beasts with torsos that double as their mouths
Goblins- gibbering mouthers (or at least something like them)
Boggards- Bloated things that spew swarms of tadpole like leeches
Ratfolk- Furry xenomorphs
Ooze- no apparent change but now said ooze is intelligent and doesn't digest it's prey but transforms it into a fleshwarp itself loyal to its ooze master.
