Well .... To be fair I'd say that SOME do benefit from a soak .
My first Royal ( albino ) was in pretty poor condition when I 'saved' it from the local pet store and she wasn't happy or wanting to eat for a few weeks afterwards .
I posted a photo of it onto a Snake forum and within hours somebody suggested that she thought it was probably dehydrated and to give it a soak in water for 30 minutes . I did everything she said and within the hour the snake had transformed into a plump brightly coloured Albino .. and she ate the very next day ...
