You find three goblins in a trenchcoat with a shack full of dubiously acquired merchandise of poor quality. They'll buy your loot for 12 silver, a shiny button, and this really cool bug they found yesterday.
If they promise to be my new best friend they can keep the silver

Hey, find a medicine man and you can actually get some good trade for those.
Apparently even today still, IIRC leaches actually do get used for legitimate medicinal purposes in the modern day. Them and maggots, I believe for cleaning out necrotic flesh.

Unrelated, but what is that black/dark grey thing on the desk?
It looks like one of those plastic desk organizer things. They usually have various slots for pens, post-it notes, etc.
They need to unload their diseased rat livers somewhere!
