in this quiz the last letter of an answer is the first letter of the next, so I already have some clues as to the answer:
14)Plain and simple one Charlie comes after some red flaky bits(6).....starts with "r"
15)He's peering over a steep rock(5)....... ends with "p"
Q16 is Pigeon is ardent supporter of the tuft at the rear(7) for which I've put pigtail, as Q17 starts with "l", and because pigtail starts with "p" so Q 15 ends with "p"
