If a frog turns up in your well and it too has an apparent ability to speak, go along with it. Your future could bode well if you're nice to the thing. (And unlike the wolf it can't possibly eat you whole!).
Note to witches: if you're keeping someone captive in a tower, do check regularly on hair growth or they will find a way to use it to escape. Also watch what you feed them? What on earth made Rapunzel's hair so strong it could take the weight of a man climbing up that tower? (Note: the Philistines made the same mistake over Samson and his re-growth of hair and from their viewpoint the story did not end at all well).
