Mr. Zebra the Postman is delivering the post and today his daughter Zoë is helping him. Zoë Zebra delivers a very special letter for Peppa & George; - an invitation to her birthday party.

Daddy Pig winds up the old cuckoo clock in Peppa and George's bedroom. When the clock strikes the hour, a wooden cuckoo bird pops out, flapping its wings and singing 'Cuckoo!', but George wasn't looking and missed the whole thing. George does not want to miss the cuckoo again.
