The Many Adventures of Winnie the Pooh
For the character Piglet, hand gestures and other movements were used by the animators to make expressions, because he (and Pooh) had the look of dolls or stuffed animals with relatively simple button eyes. The scene where Rabbit deals with Pooh's being part of the "decor of his home" was not in the original book, but was reportedly made by Disney when he first read the book.
