Yoto Says: On their Christmas holidays the Five Find Outers find themselves in a sticky situation as they stumble across a secret room. But who lives there? Let's find out!
Pip discovers a room in Miss Crump's old empty house isn't empty at all - someone has been using it! It's the perfect mystery for Fatty to put his new talent for disguises to use. Now it's up to Fatty and Pip along with Bets, Larry, Daisy and Buster the dog to find out who has been using Miss Crump's old house.
In the original 1945 text, Fatty's nickname is based on the fact that his initials are F.A.T. as well as his size. All references to his size have been removed from this recording (based on the text from 2016) so that Fatty's nickname refers to his initials only.
