Lob did it! He did it, he...didn't have any vials to catch the stuff in! There is no curse in Elvish, Entish, or the tongues of Men for this irony. 

Now lob had to think, not his strong suit. Slowly lob walked around the cave and picked 'catch' back up as he tried to figure out what to do. He needed one gland from it to get its tears, but he never cut one up before so he had no idea how they worked. As he stumbled around, he smacked a tie into onre of the little crystals from its tears and gave a roar of frustration. That roar slowed down as lob thought about it and rubbed some sleep from his eyes...

Getting to work, Lob closed the eye with one hand as he used the flat of his blade to smear the eye-gunk over the closed eye as he blew upon it, watching it crystallize in exposure to air. Now it would be sealed good enough for him to bring it back. With a pleased grunt to himself. Lob threw the eyeball over his back, adjusted the rocks in his crotch, and marched back to the cave entrance.
