Does anyone know a myth or fable in which a snake claims innocence in some deed, laying blame on 'another snake' who's now 'dead and gone,' pointing to a shed, discarded skin (it's own, of course) as ersatz evidence? Maybe it claims that it's now transformed like a butterfly or moth, or even to not be a snake at all.
This is all in the vein of 'a leopard doesn't change its spots,' or the tale of the frog and the scorpion.
