Animated tales for preschoolers about carnival denizens and a 9-year-old who works with them. 'Marvin' was cocreated by children's book authors Betty and Michael Paraskevas and aired under PBS's 'Bookworm Bunch' weekend-morning umbrella.
Viewers flipped for the megasmart dolphin that routinely helped his two young owners, Sandy and Bud, the sons of a widower living on the Florida shore (episodes were filmed in the Florida Keys and the Bahamas). Producer Ivan Tors, whose earlier credits included 'Sea Hunt,' adapted the series from a 1963 film he worked on that made a splash, and later produced 'Gentle Ben.' Flipper, by the way, was a male role filled by a female dolphin.
