I’m totally into the idea of making the mermaid black. I spend all day going, “yes, you absolutely look like Elsa. Yes, you are a spitting image of Rapunzel.” I once suggested Klara could be Anna for a change because she has more of Anna’s personality but this caused extreme offense because Anna’s hair is red. This shit really matters to toddlers. If they don’t have a character who looks like them, they get really sad. So I think adults should suck it up and deal with a black mermaid.
It’s very weird for adults to care. As long as the babies are happy, who cares what the characters look like?
