A ball is much different that is the point. The point is if they find it in you room doing an inspection or whatever your school may do they could have it removed from the campus and there isn't much you can do unless you can get them to allow you to take it back to your parents house.

Because you broke their rules for living in a dorm. I don't mean to sound mean but I know a guy the worked as security for a college and got a lot of snakes from room inspections that were done by housing.
