mr. principal is the principal for elliots high school.He has never made an apperence, only talking throw a loudspeaker and a phone (ep. 2). very little is known about him, althogh he may be jewish since mr. higglsworth calls him a jewbot. He might also be Mr cool as they sound exactly the same. It is alsolikely he is Mr cool as if the school he is running is that bad then he might have the same too laid back attitude of Mr cool.
