When does Lassie's Rescue Rangers return?

The hour-long pilot, Lassie and the Spirit of Thunder Mountain, was part of The ABC Saturday Superstar Movie. The Rescue Rangers were eight animals including Groucho the owl, Toothless the mountain lion, Musty the skunk, and Robbie the raccoon. The National Association of Broadcasters agreed: "The manufacturers of this rubbish have incorporated violence, crime and stupidity into what is probably the worst show for children"
