You're welcome. Yes, let's make Craig's scene separate.
1) When the Hyena grabs Phillips private parts, and tears them off .will that be everything in one go?
Yes, hyenas take big bites.
2) The whole experience must have been horrific . But made even worse when he sees a hyena with his genitals in its mouth?
Yes, that part was so horrifying that he lost consciousness.
3) Would the Hyena be able to swallow his private parts hole?
They chew their food, but not thoroughly. It would probably chomp down 4 or 4 times, then swallow.
4) Would the Hyena enjoy the feel and taste of that meat as it eat it?
As with many other animals, tender, fatty portions are tastier, and the hyena would think so too. Fat has a smooth feel in the mouth.
5) How long it take the hyena to digest them?
About 24 hours.
6) Would it be just one or more Hyena that eats the black denim shorts, would they be able to digest the material?
The shorts would be shredded during all the tearing. More than one would eat the pieces. They couldn't be digested, and would be found in the droppings. The droppings are mostly white and quite dry, due to the consumption and digestion of bone. The shreds of material would be visible.
