I feel like this is a reach... I know we love to nitpick but saying that she looks "manic" just because she's dancing in a weird way is a bit much. There's nothing wrong with doing childish stuff since it can be fun and moving/dancing around like that is a great way to lift your mood.
Hell, one of my favourite things to do in the garden is to just collect long bendy sticks and swing them around because why not

I love to nitpick Roobee too but I think it's nice to see her just being goofy and not worrying about doing something productive or aesthetic.
