MRC4CAT and my idea

The primordy oil is the gel like stuff the tarrs give off while moving around. Some things that support this are that it can be found everywhere, it looks like tarr, and in it's description is the Slimepedia it states: "primordy oil is an ancient substance containing a wide array of organic compounds..." Tarrs could be made from a wide array of kinds of slime and tarrs leave blobs. so you could get broken glass from drills to make empty bottles. to collect the tarr blobs
