Place all the cookies in the bowl of a food processor. Pulse a few times until the cookies are finely crushed. Alternatively, place them in a large sealable freezer bag, seal, and go over with a rolling pin to crush. 

Stir the yogurt, and fold in the chocolate chips. Spoon the yogurt into glasses or dessert bowls, and top with a thick layer of crushed cookies. Decorate with candy worms, and dig in!
