There is nothing new about practical jokes at Macdonald Hall. The latest round includes water in the swimming pool being turned blue, the statue of Sir John A. getting a snazzy new outfit, and extra soap being snuck into the dishwasher just for fun. Of course, all fingers point to the usual suspects--Bruno Walton and Boots O'Neal. The funny thing--they are not the ones pulling the pranks this time! But they are unsure just who the new prankster is, and they have to prove they're innocent before they get expelled.
