The Rescuers (1977)

Join the shy but brave mouse Bernard and his glamorous partner Miss Bianca --- two tiny heroes on a great big mission to save Penny, a young girl who has sent an urgent call for help! Taking off on the wings of the albatross Orville, together they soar to the marshy swamp of Devil's Bayou. There, they find themselves on the riverboat hideout of the hilariously evil Madame Medusa, who wants to use Penny to steal the world's largest diamond!
