Piglet Does A Very Grand Thing

One blusterous day, Pooh and piglet decide to visit everybody. After seeing Kanga, Rabbit and Eeyore, they hurry on to have a proper tea with owl.
At Owl's house, they hear a loud cracking noise.
The room tilts slowly upwards until Owl's letterbox is in the ceiling! Can piglet do a very grand thing to save them all?
