This is the story about the two lazy cats Duff and Puff. One day they jump out of the window and end up at a farm where Duff gets the idea to play hide and seek. Puff can't find Duff anywhere. Not at the chickens, not at the cows, not at the sheep, not at the horses. Can you find Duff and help Puff solve the mystery? And how do they get back home before their human comes home?
