The door had always worked perfectly well, until the day that Mr Feed-Me cut a hole in it and fitted a flappy thing. Then the door stopped working and everyone started acting a bit crazy Mr Feed-Me was on the floor using it as a window. Mrs Feed-Me kept calling to Basil through it instead of opening the door, and Small Feed-Me tried to post Basil through it like a letter through a letter box. Then one stormy night Basil found that he had a use for the flappy thing after all.
