i was too (and why everyone was going on about how the big red/orange one is A LITERAL SHITLORD) and then a few days ago someone linked me to a clip on YouTube that shows that she's really obviously meant to represent a victim of abuse.
it's only about two minutes long and pretty well done for a kids show.
so of course now she's the patron fucking saint of abuse victims everywhere according to tumblr. you would seriously think they've never seen a TV show with an allegory for abuse before, or with a main character who came from an abusive background. of course, a lot of those characters usually seem to have their shit together and have tried to move past their abuse and don't enjoy being patronized for their past, so tumblr wouldn't care anyways. the one from SU is the most important because she's a precious delicate flower child that needs to be protected uwu.
