The answer to the mutations is not biological. People are not turning into animals, they’re turning into their concepts of cartoon character animals. I don’t hold with the notion it’s to do with DNA changes or any other matter of biology.The changes are not even obeying the laws of physics (or at least the physics of a closed system). People mutate into forms with lesser or greater mass than they started with.The answer is far more metaphysical – it involves shifting dimensions, influenced by the subjects concept of body image. Because there are some definite patterns as to animal or monster, then it’s not entirely subjective and the circumstances do dictate some of the results. But Flask for example was a cruel, scheming human and she became a cat. Holly was a… well, she was probably timid and agile at heart and she did wish she could eat more cheese. So she became a mouse. I suspect each person who mutates is actually slipping sideways into a dimension where everything else is the same except they are a mutant because they ‘always have been’ (as far as this new reality is concerned).Although the mutations are not caused by a virus, they do behave in the manner of a communicable agent, almost without exception. The change will occur even if the subject is not aware of having been exposed, and even (I think) if there is no observer either. So there must be some independent factor going around and causing it. Neathery has not chickened out from explaining it. I have worked out all the above by myself, and that much is fairly plain. His concept is more science than magic or fantasy. This is Endtown, not Harry Potter. What do you think?
