After the Muppets became international stars, Jim Henson set out to experiment with his characters. In 1983, he created a new world of Muppet characters for HBO -- Fraggles. "Fraggle Rock" aired from 1983 to 1987. Unlike the vaudevillian style of the Muppets, the Fraggles reflected Henson's interest in fantasy. He would further that interest in the feature films "The Dark Crystal" and "Labyrinth."
