If I may just take a moment to confirm Oz references (even though it’s quite late): Tip was the name of Ozma, queen of Oz but magically transformed into a boy before her true identity was made known, and she was returned to her female form. Moustachio is analogous to Tik Tok the mechanical man. Even look alike. Nick the man tuened into metal airplane relates to the Tin Woodman whose real name was Nick Chopper. Unity, sewn together from body parts reminds me of the Patchwork Girl. Gavot is a swarm of bees not unlike the swarm in the original book. Did I miss anything?
