I'm so happy to learn the title of this movie. I remember it being shown to our elementary school in the 80s when we'd a have special movie day in the gymnasium where all grades got to watch. I thought I recalled it being a projected movie, but if it was a TV movie, then it must have just been something one of the teachers recorded and played back on the "giant silver top loading VCR." Same as a poster up above, I wasn't even sure I had really seen this or imagined it. The movies that stick in my mind from elementary school viewings are Seventh Voyage of Sinbad, Disney's Ichabod Crane, the Pippi Longstocking movies (I had no idea as a child that she was poorly dubbed) and now that I know the name, Sammy's Super T-shirt.
