When Mrs. Cramp decides to extend her kitchen to accomodate a new autoclave for sterilising the dishes, Wayne suggests they save money by doing it themselves. With Mr. Cramp’s consent and encouragement, Wayne knocks down the kitchen wall and almost collapses the whole house. The family ends up having to survive together in a cramped hotel bedroom until the works are done. This is not easy. Lucien then realises he’s forgotten to bring his worms and has to go back to the house to rescue them. Wayne follows him and blackmails him into colluding in a candybar fraud.
