"Lock, move over!" complained Shock. "Why don't you just make me?" Lock growled back. "Look we're almost there!" said Barrel. A few minute later they arrived at trick-or-treaters school. They parked their walking bathtub and walked through the front door. There was a black carpet and white walls. Spider webs covered the ceiling. "There's the principal's office." Shock pointed out. "Who are you three?" asked the principal as they walked through the door. "Lock!" said Lock. "Shock!" said Shock. "Barrel!" said Barrel. "Oh, the new students." said the principal. "Welcome to trick-or-treaters school. Here is the key to your dorm room, Lock and Barrel. Shock here is the key to your room, you get one all to yourself because all of the other girl's rooms are filled and it's the only open one." They went to their rooms and put their stuff down. It was about 9:30pm when they got there so by the time they got settled in it was 10:00 and time to go to sleep.
