Mr Sawdust and Karen are washing the car, and Olga overhears them playing with the hose, or 'the snake' as Mr Sawdust calls it. Olga tells Noel, Fangio and Graham that there is a dangerous snake loose in the garden.
Olga worries that Karen will be dressing as a cat like Noel for Halloween. But to her delight, when Karen comes out to show off her costume, she is dressed as Olga.
