The Mighty Jungle told the story of Dan Winfield, a zookeeper who lived with his family in a large enclosed rainforest, and who on taking up his new job was amazed to find that – the animals could talk. Vinnie, the Brooklyn Sewer Alligator, Jack, the Californian Circus Sea Lion, Winston, the British Orangutan and Viola, the Latin Toucan, all interacted with Dan and his family – his wife Susan, and son and daughter Andrew and Alison (although only Dan knew his animal friends could talk) – in a series of half-hour adventure stories.
