I have not seen the video. Generally if a ball is trying to bite it is for a reason. Number one reason being because they are scared. If you don't want to get bit you have to make the animal feel comfortable. Let it know you are there. Pick it up in a confident manner. Try not to put it back until it calms down and relaxes. I don't know what kind of morph you have but the only animals in my collection that have had a go at me are pastels. I have four pastels and they are all flighty. My killer bee is the absolute worst. That animal thinks everything is trying to eat her. I work with her every other day at this point but she still thinks she is lunch. It is the only snake I have I won't let my kids play with it. My other pastels do not like to be handled very much. They don't try to bite any more but they really do not want to be held. With spastic larger animals i will hold them like a baby and they seem to feel more secure and calm down. Babies you are better off just cupping in your hands.
