The Crally Twins went to school with Raven and Stu, and they were a teachers worst nightmare. The two boys never spoke to an adult, and could not be parted. They dressed the same, and look exactly the same. Since know one could distinguish who was who, and the boys never talked, everyone forgot their real names and started calling them Crally One and Crally Two.

Crally One is the one one the right, Two is on the left, no one is really sure if they switch sides or not, it's just easier that way.
