you've got to be kidding! the most that could attack you at once is like 3, and you could easily punch them in the face, one at a time, and they'd stop fighting.
3??? I don't think so.... I agree that their physical abilities are low but if they were smart than they would attack you from all sides simultaneously
You could take on 21 five year old kids in a fight. Nah, I can take on much more. I would say about 35-45.
