Place Oreos in a large zip top bag and seal. Finely crush the cookies with a big rock. Open the bag and mix in the cream cheese until well blended.
Roll cookie and cream cheese mixture into 1 inch balls and set aside.
In another zip top bag, crush the candy canes. Toss each dirtball into the bag of crushed candy canes, pressing the candy cane pieces so that they stick to the outside of the dirtballs.
