LOL..Barreth, you crack me up. Anyhow, about the boiling water. It just proves of how heat resistant a Yautja is. I mean, c'mon, their homeworld Praedra (Pray - Dra) has an annual average temp of well over 150 degrees so, they've built up quite a resistance to any form of extreme heat. Also, dont worry, I didn't go to Praedra and take instrument measurements lol, but, this is all very credible info from books and websites. Also, about the syringe. Take into consideration the Yautja's supreme technology. Perhaps they had to develop a really advanced sharpness to the syringe to just allow it to penetrate. Take into account of how strong a Yautja is. He was pushing on that syringe when it penetrated. If it was a human trying to stab him with it, it may not have gone through since he would be considerably physically weaker. But you're right in the fact of how the flesh gave way when it went through, made it look rather soft.
