This comic depicts a variation of mammalian pregnancy where baby is connected to the mother with a cord on the crown in a similar fashion to stalk pregnancy. Common mammalian pregnancy involves babies floating in mother's filling, which is used to nourish them when they have developed their mouths (siblings can be food, of course).
