Filbert the Good Little Fiend

In the demon kingdom, bad is good and good is bad
Everything works in reverse in their world. Daddy and Mommy Fiend want their little Filbert to be gruesome and ghastly, but he won't trample or terrify, roar or holler. He'd much rather help an old lady with her bags or go bird-watching. What are they to do with him?

When Filbert starts school, he quickly learns that good behavior isn't tolerated in class, and he is banished outside until he can act like a proper little fiend. Suddenly a little angel appears, flying fast and furious until... bump! Could this naughty Angel-School dropout be just the friend Filbert needs? Could they find a way together to make everyone accept them as they are?
