Mr and Mrs Frog run a charming little Lost & Found shop in the middle of a large city. Their tiny premises is overflowing with lost items which they hope to reunite with their owners. One day a mouse enters and asks them for help – but he can only speak French.

He is desperately looking for his ‘chapeau’, but as Mr & Mrs Frog can only speak English they are confused. . They muddle around the shop, pulling out objects at random and waving them questioningly at the mouse. Each time the mouse shakes his head. He’s not looking for ‘un parapluie’, ‘un manteau’, ‘des lunettes de soleil’ or ‘un pantalon’. He definitely hasn’t lost any ‘fromage’ or ‘un ordinateur’ or ‘une banane’.

All the mouse wants is his ‘chapeau’ – but how can he explain that to Mr & Mrs Frog?
