I thought that as well (I also thought of the "Planet Hydra Incident" that Isamu had some part in, according the file on him that Guld tapped into), but enh, whatever. My biggest problem with the Hydra is that, in Mac Plus, it appears that life on Eden is very young and primitive...nothing has quite evolved out of the age of the dinosaurs, and yet, the Hydra looks like a rather more complex lifeform.
Not to say that it COULDN'T exist on Eden, but the difference between it, and the pterosaur and the pelican thingy is a little TOO pronounced, I think...like if they had a new Zolan lifeform that wasn't a marsupial.
