Flying lessons?

Somebody once said "An apple a day keeps the doctor away, and an onion a day keeps everybody away". I suppose that when that pearl? of wisdom was coined, years ago, Pickle and Pearl had not been 'discovered' yet. Which makes me wonder with wonder why this angel (Goddess, whatever, Balinese?, I don't know, do you?) wanted to take flying lessons from our intrepid adventurers. I would have thought that 'angels?' would have taken to flying naturally, but what do I know? Be that as it may (another stupid expression) That is the situation as the picture sees it, and who can argue with a picture?
