When Posy goes to stay at Pip’s house, they have lots of fun together before bedtime. But just as they switch out the light, disaster strikes: Posy realizes that she has forgotten her favorite frog toy. Desperate to help his distraught friend, Pip offers Posy a range of different toys to substitute for her frog, but none of them will do. It is only when Pip gives Posy his very favorite pig toy that Posy is comforted and the friends can get a good night’s sleep at last.
