Winnie the Pooh is a bear from the Winnie the Pooh Books by A. A. Milne, but is most famous for his many cartoon adaptations by the Walt Disney Company, going back to 1966. He has many friends in the Hundred Acre Wood including Eeyore, Gopher, Tigger, Piglet, Owl, Kanga, Lumpy, Roo, Kessie, and Christopher Robin.
Homer is attacked by a bear at the Springfield Dump. The experience traumatizes him. Later at his home, he imagines fictional bears, including Winnie the Pooh Smokey the Bear, Snuggle the Fabric-Softener Bear, two large bears wearing Chicago Bears uniforms, Gummi Bears, Teddy Grahams, Baloo, Fozzie Bear, Rupert Pudsey, Yogi Bear, and Paddington Bear, marching towards him.
Winnie the Pooh was voiced by Sterling Holloway until his death on November 22, 1992, then Hal Smith along with Owl until his death on January 28, 1994, and now Jim Cummings voices Winnie the Pooh and Tigger as well.
