If you want some strange fantasy or alien biology, just take some existing real world biology and file the serial numbers off. It works especially well for obscure insect and parasite stuff that most people aren't very familiar with, but you can also use well known things - like bees for example.
Bees collect nectar from plants to make honey. So imagine some creature—and let's make it not flying—that collects... sweat from other animals, to turn into salt cakes. These are a common thing in your campaign world, and nobody gives them a second thought. Instant weirdness!
Commentary by memnarch (who has not seen the movie)
Hahaha! I wonder if General Hux is aiming to get Kylo removed; this seems like a great way to sow some extra discord between Admin Snoke and Kylo Ren. And as a bonus, Ben gets to tease his sister! That's always fun when there's a back and forth, and Sally's still up from last time.
Kylo being sans helmet here seems really strange. He wore that thing everywhere previously, including the last meeting with Snoke. Why give it up now? Did he just come straight from the interrogation room and forgot the helmet? Kylo looks so much better with the helmet on, even with how goofy it is from the sides.
Snoke is nicely menacing still; I hope that keeps up. And that he sticks around as the final big bad in all the movies. .....and that he's actually as menacing there as well. The giant hologram is perfect for surprising and scaring Team Good Guy at least once before the metaphorical curtain gets pulled back to show he's normal-sized. Movie-wise, Snoke is also probably the one coming up with the idea of trading Rey for the map. Even excluding the dialog, something about Kylo makes me think he's not the big ideas person for the First Order.
GM: Back on the Peace Moon, Administrator Snoke demands a report. Sally, some dialogue notes for Snoke.
Snoke: So, what have we learnt?
Kylo Ren: I’ve captured Rey Solo.
Snoke: Didn’t I tell you to just kill her?
GM: General Hux walks in. Ben a note for you too.
General Hux: I think he has a thing for her.
Kylo Ren: Ew... What?
General Hux: Boy Force user meets girl Force user. You know how it goes. Midi-chlorians in the air.
Kylo Ren: That’s not how it works.
General Hux: Perhaps there are space bees involved. I never did figure that out.
