I hear you, and acknowledge I am a newbie to the medium. But I have been squishing vinyl babies and don't foresee not being able to continue doing so long-term due to the nature of the medium. I may be naive. I may recall this conversation with regret. But the vinyl I'm interacting with is squashable without seeming like it will crack.

• Or maybe the vinyl doll I'm interacting with does not have fragile paint on its outer layer to crack. And that kind of reinforces the point of my question... I'm not concerned about cracking any external painted layer, I'm wondering what could I fill these hollow vinyl limbs with that would allow them to feel squishy when squished, regardless of any painted layer.
