Adam gave some great advice on this. But first they are right the S neck thing is normal. My Odin is kinda hissy. He likes to puff up and blow its no biggie. And now for Adams words of wisdom. If it worries you reach in from behind the snake. As you do touch its head with a water misting bottle or somthing. Just touch it's head they will move their head back and stop the the S position and then pick him/her up.
