This has bothered me for years but I remember taping a movie off the CBC that aired possibly in the late 80s or early 90s with a pink dragon and 2 kids and a magic key. All I remember is that there was a boy and a girl, they had to use or find a magic key that would open a door. There was a Jim Henson-style puppet dragon (kind of dopey in his actions and voice) that was helping them along their quest. I remember the key they had or were looking for was gold with some stones in it. It might have been a made for TV movie or a TV show. The dragon was big, life size I guess, and was a pinky purplely colour. I don't remember much more because I had taped over it by accident with the Fluppy dogs movie. This movie was live action and I believe the kids were siblings. Any help figuring out what movie this was would be great!
