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?
Based on the Winnie-the-Pooh works by A.A. Milne and E.H. Shepard
