  Then there was the Gryffindor Trio, Daniel, Janet and some other boy named Thomas Jefferson, a muggleborn. They were also calling themselves Marauders for some reason or another and were pranking everyone. They spent much of their time pranking the Slytherins who weren't even bothering with them. Some hexed them in passing but they just went and cried to Dumbledore. Though the headmaster didn't take sides it was obvious he over looked some of these Marauder pranks that the Slytherins detested.
