Seconded Eating the Creeper that has no sweeper in it.
Seconded after eating, research how the Muk moved.
I figure that since we ate some of it, even though we vomited it out it should be good for DNA to grow jets. I also think that we might want to somehow form a symbiotic relationship with the Creepers after a while. We can let them grow on us and protect them from Sweepers, in exchange for food either by photosynthesis or just eating spare parts of them. We could even let them sprout in the left overs of the dead creatures we eat.
This is all longterm goals though.
