I went i enjoyed this and completed it before I came here, which is unusual. I am less precise than Chrise but I was definitely put off by the wrong definition in 19A, I don’t think a theme forgives such a complete mistake - I don’t know the theme at all and am only defining it from the chat here
I have to throw a word in support of the dog in 12a, who provides some of the best TV for any age ever. Look for ‘Sleepytime’ or 'Camping’ - this is the Dickens of kid’s cartoons! I think all series are on Disney +, with only a (changing) selection on BBC IPlayer. I read that Disney considered changing the Darwin accents for US audiences but the original producers rightly said no.
