 ::Thanks for the reply. I disagree that the blood is more significant that the drooling. The drooling sets up every single alien encountersome fool always steps in it, and then BAM. Although it is not covered in the body, it should as it is pretty central to the identity of the Xenomorph. And yes, it should be in the secretions section. But I do think the drooling is one of the central signatures of the creature. and a continuous visual motif.
