I think what I said the first time is still the reason. They didn't change baby AJ's eyes until last season after all and the first time we saw her was in season 3 when Flurry wasn't a concept and the twins were the only babies. They might have been testing the eyes on her and they either forgot she had the dot eyes or didn't care. I think there's another reason too, toys. If a Flurry Heart toy had the dot eyes, there's a good chance of it looking very creepy. I've seen it done right before on twins' plushies, but hasbro wouldn't care too much for getting the eyes right. That and it's also easier to make toys if you use the same styled eyes on every character.



Sorry if that's a bit long. I love thinking of reasons why things are the way they are and once you get me thinking, I don't stop. xp
