BAW, nostalgia is a painful mistress. I would buy Cartoon Network stock just to probe for a spinoff. My only thoughts are on how to make it better. That is to say as cool as a monster school is, its been done just a bit too much to be completely fresh and only has so many stories without something more to it. Its not hard to compete with Monster High's stories, but some staying power would be nice.
Wow, I did not expect to see them again. In fact, I wasn't expecting to see fan art of Scooby-Doo and the Ghoul School at all. Once I saw this, I immediately remembered that movie. Too bad they were a one-time deal. Hmm, I wonder if there's fan art of the Boo Brothers too?
