Winnie the Pooh
Winnie the Pooh is a book by A.A. Milne about a bear "of very little brain", called Winnie the Pooh, and his friends in the Hundred Acre Wood. Among his friends are Piglet, Rabbit, Eeyore, Owl, and Christopher Robin.  Milne wrote a second book about the characters, called The House at Pooh Corner.
Disney made several popular short films (and recently many other less popular feature-length ones). Walt Disney personally took part in creating Winnie the Pooh and the Honey Tree and Winnie the Pooh and the Blustery Day. Sterling Holloway was the original voice for Pooh.
