Poohsticks was invented by English author A. A. Milne for his son Christopher Robin Milne. The game first came to prominence upon Milne's description in his 1928 book "The House at Pooh Corner", as well as the 1983 Disney animated featurette "Winnie the Pooh and a Day for Eeyore". As first depicted, protagonist Pooh accidentally drops a pine cone into a river from a bridge and, after observing how it appeared on the other side of the bridge, devises the rules for Poohsticks, later playing the game with the other characters, Christopher Robin, Tigger, and Eeyore.
