I'm trying to workout the blooodbugs
they feed on tissue which turns them into bulbous masses of blood. I guess they digest all this and grow larger or into their next form.
They shit out eggs of themselves which are little tadpoles, they aim to get these into a host, which then grow into mites that feed on the organs internally
However we also see one of these crawl into a dead human body through a wound in the last episode. What's that about?
