Flipper, from Ivan Tors Films in association with Metro-Goldwyn-Mayer Television, is an American television program first broadcast on NBC from September 19, 1964, until April 15, 1967. Flipper, a bottlenose dolphin, is the companion animal of Porter Ricks, Chief Warden at fictional Coral Key Park and Marine Preserve in southern Florida, and his two young sons, Sandy and Bud. The show has been dubbed an "aquatic Lassie", and a considerable amount of children's merchandise inspired by the show was produced during its first run. With the Ricks family, Flipper helps protect the park and preserve its wild inhabitants. He is also instrumental in apprehending criminals and thugs in the park. Flipper is generally recognized by the characters in the show (and the theme song) as being a particularly intelligent and capable dolphin. Flipper is the special companion of the youngest member of the Ricks family, Bud, and several episodes feature Flipper rescuing Bud from dangerous situations. Flipper is able to somehow communicate through different chatter like tones, head nods and shakes and others attention seeking antics with Sandy and Bud and draw their (and Porter's) attention to danger or in the direction of people needing help.
