Continuity mistake: In 'The Frog's Legacy' (1987), Del & Rodney learnt the story of Freddy The Frog for the first time - neither of them had ever heard of him before (Aunt Irene explains to Del who Freddy was. She mentions both 'Freddy The Frog' and his real name 'Frederick Robdal'. Del has heard of neither of these names). Yet in 'Sleepless In Peckham', it would seem that Del had known Freddy since he was 15. He even went on their first Jolly Boys' Outing with the rest of the gang.
