When Tad Stones first came up with the idea for the Rescue Rangers series, Chip and Dale were not part of the show. He initially pitched doing a TV series based on The Rescuers, but Disney rejected that idea as a sequel to that film was already in production. He created a new concept with the working title of Metro Mice. In the original draft, the main character was an Indiana Jones-type mouse named Kit Colby who sported a fedora and a fluffy collared leather jacket, and the rest of the team included a chameleon, an earlier version of Gadget, and a character resembling Monterey Jack with a different name. When he proposed the show in a meeting with Michael Eisner and Jeffrey Katzenberg, the idea was well received except for the character of Kit. At Eisner’s suggestion, they replaced him with the chipmunk duo to give the show some established Disney characters to work with. By late 1987, two years before its television debut, the show was announced under its original proposed title of “Chip ‘n Dale and the Rescue Rangers”.
