please help

[The Serpent Merchant]

looks a little on the thin side but he looks very dry and possibly dehydrated.
Soak him in a half inch or an inch of warm water in a container (obviously one he can breathe out of) for about 15 minutes. This should help loosen some of that shed and help hydrate him. I would repeat a warm soak again the following day and then see how he looks.
And I would say that snake could eat rat fuzzies no problem, or mouse hoppers.

if he is actually in shed this could actually be detrimental. I would focus on getting the humidity up, and then go from there.
