My Friends Tigger & Pooh is an American computer-animated children's television series inspired by A. A. Milne's Winnie-the-Pooh. The series features Pooh and other characters from the book and prior television adaptations and introduces two new characters: 6-year-old Darby and her dog Buster. Darby is the main human character, but Pooh's owner, Christopher Robin, makes two appearances over the course of the series. Developed by Walt Disney Television Animation, the show premiered on Disney Channel's Playhouse Disney block on May 12, 2007. The show's theme song is a pop song that is played at the beginning of each episode. It was written by Jellyfish lead singer Andy Sturmer and is performed by former Letters to Cleo singer Kay Hanley. In Season 2, Chloí Grace Moretz as Darby (replacing Kay Hanley) performed the theme. Also, beginning with this series Travis Oates assumed the role of Piglet, taking over for John Fiedler, who died in 2005, two years prior to the debut of the series.
