I've figured out what two chemicals in the brain allow for the brief processing of skeeve and from that I think I can quite safely begin to extract it using a simple peice of apparatus like the diagram above. sadly what I lack now is a reliable source to allow the reaction to take place in the first place. obviously because a sponge can't see or think it also can't recreate the exact process that attracts skeeve normally so I'll need to find another way around it.

So for the moment, what is the exact source of skeeve? what is it's most basic form? If it were that easy to find, I wouldn't have to go through all this stuff with human brains and sponges.
