Andy Pandy was a character whose dress closely matched Sarah Jane Smith's when she was hospitalised. When Doctor Carter reported her theft of Eldrad's hand, his description of Sarah — "a dark-haired young woman wearing some pink striped overalls" — was likened to Andy Pandy by the receptionist he telephoned. (TV: The Hand of Fear)
Bryony Mailer was also reminded of Andy Pandy when she saw the overalls in the TARDIS. (PROSE: The Drosten's Curse)
