Whoa there, settle down. I would fill a large bowl of cool water and let the little fellow soak. My guess is that the humidity isn't that high in the viv right now. Also, it is a good idea to get a tupperware (a size that can fit your snake) cut a hole in the side, add some moist vermiculite (can be purchased at the garden center of most store and in some pets stores. I boil mine first to make sure it is clean), reclamp the lid, and the place it lid down so that the snake can get into the hole. This provides your snake with a nice moist spot that it can moisten it's scales with. This should help all future sheds. I will surf the forum for the pictures someone else posted about their 'tupperware' boxes so that you can get a better idea of what I am talking about. Also, if your little guy won't go into the bowl to soak then you can get damp paper towels and wrap him in them or offer them to him to get into himself and see if that works. Some corn snakes just HATE water, my female okeetee likes it ALOT and the male doesn't want anything to do with it but to drink from it. Hope I helped and I will keep looking for those pics!
