what is "ink" up to?

For me, the main question is - What makes them little and were they ever human in the first place?

Consider this, the zombies are alive, how would they give birth? I'd imagine them eating their way out (lovely image)

The Little One's could be changed children, changed apes, some new permutation of a regular zombie or newborn zombies.

Does anyone know of an animal whose young kill it in order to be born? The reverse of Traumatic Insemination.
