Like said before, it produces cementing paste and organic polymer.

Pro tip 1: put it in a wooden cage and set it on wandering. He cant escape, and you wont have to build a pen.

Pro tip 2: put the organic polymer with oil in a cooking pot. I think its like 3 organic polymer and 3 oil to make soap. Soap doesnt spoil. When you need the polymer you can put the soap in the grinder and grind it for like 1 polymer for 1 soap. You lose some polymer but it doesnt spoil.
