For being a fairly decent cook and baker, I'm horrible at making RKTs. I use them already boxed which, I know, is more expensive overall but they dry so well and so hard. I know that's does not help your current situation...
That being said, if the body parts are not affixed, you can roll them in some corn starch which might help dry them out. Coat them fairly well so the corn starch covers the surface. Then brush off the excess with a soft feathered paint brush. Let that sit for a bit. The corn starch should help to adsorb the extra moisture.
If your area is humid, it might be a different situation altogether... then you are fighting a losing battle. However, still try the above method.

here is another dumb question. Do you have a recipe for them you can share

it's usually on the box of rice krispy's, just cereal marshmallows and it calls for butter, but if your using for a sculpter, it may work better without the butter
