Kessie is a small bluebird adopted by Rabbit, after he saved her life during a snowstorm when she was just a nestling. Also, she tends to call Rabbit "Rabby", a name she gave to him when she was a baby. She first appeared in The New Adventures of Winnie the Pooh television episode "Find Her, Keep Her" in 1988. Rabbit raised her for a many months, until she was ready to fly south. It was very difficult for him to let her go. Kessie reappeared twice to visit Rabbit and the gang: in the episode "A Bird in the Hand" and during Christmas, at the end of the special Winnie the Pooh: Seasons of Giving. To date, her only appearance outside of "The New Adventures of Winnie the Pooh" is in the series The Book of Pooh, in which she appears in many episodes, and in The Tigger Movie.
Kessie is an inquisitive bird and eager to prove herself. In "The Book of Pooh" episode, "Kessie Wises Up," her curious nature leads her to ask Owl to teach her everything that there is to know. She sang the song "I Want to Know Everything Now" to express this. Owl didn’t think was possible, but did advise her to go out and explore, observing what she saw around her, as this is the best way to learn. In "It's a Bird? Yes!" from the same series, Kessie styled herself as a caped superhero known as the Plumed Protector but due to not knowing the meaning of being a superhero, was concerned only with vanity, until Owl told her.
Kessie was voiced by Laura Mooney and Tracy Rowe (during The New Adventures of Winnie the Pooh and Winnie the Pooh: Seasons of Giving) In The Book of Pooh, she was initially voiced by Stephanie D’Abruzzo and later by Amanda Maddock. It is unknown if Kessie will reappear in any future Winnie-the-Pooh material, as she did in "The Book of Pooh". It is uncertain as to how Kessie got to the Hundred Acre Wood, as bluebirds are not found in Britain and it can be assumed that the series is set there.
