When does Fraggle Rock: Rock On! return?

Fraggle Rock debuted in 1983 as one of the first shows involving the collaboration of Henson International Television (HiT Entertainment from 1989), the international arm of Jim Henson Productions. The producers made the series with the intention of it airing in various forms internationally. The human "wraparound" segments were produced separately in several countries, so the viewer could always relate to the world of the program. The original North American version, filmed in Toronto, features an inventor named Doc (played by Gerry Parkes) and his dog Sprocket.
