That could simply have to do with the atomic makeup of carbalite. It may very well be either a highly adhesive mineral, or it could react with the molecules that make up Jhen's hide and create some sort of molecular bond. This could even have developed as part of jhen's evolution so that it could utilize the carbalite as added protection against attackers. Basically, the longer it lives, the better protected it is against attack. Seems like a good adaptation to me.
