The series follows a 7-year-old girl named Lucy who lives next door to a Zoo at 64 Zoo Lane. Each night, she is told a story by the animals. Characters include Georgina the Giraffe, Nelson the Elephant, Tickles and Giggles the Monkeys, Boris the Bear, and Molly the Hippopotamus. The cartoon emphasizes friendship and responsibility. At the story's end, friendly morals are discussed, then bedtime is declared. Georgina deposits Lucy into bed via the bedroom window (later episodes show Lucy yawning and then sleeping soundly in bed; in the original episodes she would be lulled to sleep by the storytelling itself). This has shown on CBBC, CBeebies and CBeebies Bedtime Hour, Noggin, ABC For Kids and lots more Opportunities for learning: exploring language and vocabulary are enhanced by the use of intonation and expression in the character's voices and the themes of the animals' stories support social and emotional issues, including friendships and helping and caring for others. The creator of the TV series, An Vrombaut, also wrote and illustrated six 64 Zoo Lane picture books based on stories from the TV series.
