Yes, I've been a Marvelous Melmo fan for some time now. There is actually a series based on it, but it's hard to find more than a few clips... It was made by the same guy who created the orignal Kimba (excellently remade as The Lion King, by Disney - but that's a secret. They won't admit it.) And Astro Boy, which has been remade into a CGI and is being released this weekend.
