I've been trying to figure this movie out for years. I watched it when I was a kid and all I remember is that it's either 1980 or 1990 movie. It was a cartoon, and very dark looking. There was a boy and a girl creature, they had a weird color to them and they were underground trying to out of the underworld. I just remember at the end of the movie the ground had shattered and light came down through, where they accomplished there journey.
Any ideas of what this film could have been?
