Going to shed or something else?

If it was sold to you as Colombian BCI, that's most likely what it is, but you won't know for sure without knowing its heritage.

The boa's belly looks fine to me. When my boa sheds, his belly gets a little wrinkly and the pinkness varies so sometimes it doesn't look pink and sometimes it looks almost bright red. It always goes right back to normal once he sheds. I'm not really seeing anything on the ball python except for a scale right above its eyes that looks like maybe it's dried out a bit.
