Its an interesting trek, but one that's going to get a whole lot more interesting.
Introducing the siphonophores. This creature lives on our own planet, living in the deep waters. They grow by cloning body parts and rapidly become a sprawling mess of specialized body organs. One set of body parts might provide locomotion, another set for reproduction, another set for feeding, etc. The cloned parts act more like a colony than a single bodied organisms. But these miss-mashed creatures can extend up to 100 feet.
It looks like next weeks adventure is going to get a whole lot more interesting. They might kill part of it, but there will be a little more.
