Let him do it on his own. Sometimes they take a little while to get it all off. If you want to help, try misting him with a spray bottle on the affected areas. Fill it with warm water, it is less shocking to their system than cool water. Make sure it is not too hot though. That is what I do for mine, and it usually works. Don't pull on the skin, it can hurt them. Just make sure that his hidebox is moist, and use the spray bottle. Post again if it doesn't work, or if you need more help. Hope this helps.
