Dear Claire,
Nice to virtually meet you.
When I was growing up on Guam, we had a gecko that I fell in love with that was a sort of baby blue with pink spots, rather large through a child's eyes, maybe 6 inches in the body and then there was the magnificent tail. It came out at night on the other side of our house screens from the boondocks. I was amazed partly that something so large could walk on the screens and not fall off, and of course I loved the colors as opposed to the other brownish geckos and the size, for the others were much smaller and hunted for them in the day without seeing a one? Are you familiar with this glorious gecko and what is it's name? This was the year before our first TV which we got back in the states so the snakes of midday and the geckos and insects of night were kind of primo0 kid entertainment.
btw, don't know what is a brummie lass nor a yum yum
