A. A. Milne named the character Winnie-the-Pooh after a teddy bear owned by his son, Christopher Robin Milne, on whom the character Christopher Robin was based. The rest of Christopher Robin Milne's toys – Piglet, Eeyore, Kanga, Roo, and Tigger – were incorporated into Milne's stories. Two more characters, Owl and Rabbit, were created by Milne's imagination, while Gopher was added to the Disney version. Christopher Robin's toy bear is on display at the Main Branch of the New York Public Library in New York City.
