by crystal do you mean transparent? i'm not familiar with anything that is called crystal being skwishy skwashy. i mean other then there's a character named crystal whom i'm sure has some skwishy skwashy body parts, but her skull isn't transparent nor skwishy either. i have seen some pictures of clear glass or some clear substance sculpted in the form of skulls. these did not however, appear to be particularly skwishy skwashy either.
