I honestly wasn't expecting that! Many thanks to ChrisE, KT17, PeterM and JWS for the votes, and to Dorrien for the mention. Cheers, Mattrom, for the challenge, my prize (is it just humans that are getting bigger and fatter while every other animal has been shrinking?) and, of course for your casting vote. Commiserations, KT and Tyke. Both of your clues were on my shortlist. Until next week.....
Best wishes, all
SW
