-"the red toy makes no sense": subjective. It's not abnormal. And it's potentially there to give a sense of disorder. It's not a hand with six digits.
Nah, I don't think the AI purposely choose that red toy to create a sense of disorder, since the main theme isn't displaying a sense disorder.
It probably looks like that because the AI doesn't have a clear idea of what that is from the data so it's somewhat distorted, then you see the image and feel a sense of disorder from the final result, but it is likely not the initial design goal.
which is a common problem you would see in AI generated images tbh.
