It's funny what stays with you from books.
First of all, let me say that I'm aware that
Tik Tok of Oz is generally considered to be a weak Oz book. There are a number of character inconsistencies. Betsy is a poor Dorothy substitute. The Shaggy Man and Polychrome have met each other before this. Reading this as a grown-up who is currently re-reading the whole series, I see these errors and acknowledge the point.
Still, I have to say that as a child, this was one of the Oz books that stuck with me the most strongly. First of all, Polychrome was one of my favorite Oz characters, and I loved every book in which she made an appearance. Second of all, I was secretly quite sympathetic with Ann of Oogaboo. Even at a young age I wasn't very fond of Ozma, absolute ruler. Third of all, I was absolutely fascinated with the Rose Princess, and the idea of a royal family grown on vines. I was heartbroken on behalf of poor Ozga by the reception of her subjects. Something about that bit stayed with me quite strongly, entering my personal mythology.
I do think that the plot is reasonably well-formed in this book, compared to others in the series. While adults may take issue with some of the errors, there are many aspects that I believe would appeal strongly to children. At least, I can say that it certainly appealed strongly to me. As a kid I was reading these from the library, and I must have checked this particular book out twenty times. That's certainly got to earn it some points.
