"The game's story is simple; Banjo and Kazooie are a bear and breegull duo, with Kazooie living inside Banjo's small blue backpack. One fine day, the evil witch Gruntilda decides she's just too old and ugly and sets out to find a young girl whose youth she can take for her own using her youth transferral machine. Unfortunately, the girl she decides on happens to be Banjo's sister, the innocent Tooty. Suddenly swooping down from the sky, she snatches Tooty and takes her back to her lair. Banjo and Kazooie are shocked, and set out to rescue her."
