short story, hard to explain.

Try to explain it

well
copepods are real creatures in fact,
but instead of being 20 foot long shrimps with hands, they're microscoping creatures.
they look fairly similiar to the one from the Mystery Flesh pit, albeit much smaller.

Woah
That actually makes sense

so in the flesh pit they're basically meant to be up-to-scale with the superorganism they live in
pretty smart stuff actually
