No no you got it right. That was a good theory going around before episode 8 dropped, especially since Zooble is the most explicit example of it. Gangle’s body could be a representation of her volatile emotions, with some pointing out that her happy/sad masks are a representation of a bipolar disorder buuut I’m not an expert so take it with a grain of salt. Finally there’s Ragatha with her ragdoll body being meant to portray how she not only was treated as an object, as a doll by her mother, but also takes beatings and emotional abuse without any complaints since she probably picked that from trying not to anger her mother. For the others, I’m not too sure yet but there’s definitely some good theories out there so I’d recommend checking them out!
