BOth of mine are babies and I know exactly what you are talking about. My BCI is a baby but as far as I know "Likes" to come out. He is very active, tongue flicking and likes to expolre, but my baby ball (im getting used to using ball python now) just seems to sit them like "yeah look at me" but doesn't move as much. I think just in general BCIs are more active, well as babies I have found anyway.
