The weather is turning colder, and Olga overhears the Sawdusts talking about preparations for the winter. Her imagination goes wild, and she tells Daisy and the other animals to get ready for a polar adventure inspired by her story of Sir Ernest Piggleton. Daisy dutifully practises by building a hay igloo, but it turns out the guinea pigs are really heading into the Sawdust's cosy house for the winter.
