I'm desperately hunting for some cartoon from my childhood days;
I've already looked in so many directions, it's amazing that I find nothing, aside from other people vaguely making similar mentions in forums but no info really turning up?! Maybe somewhere here does remember it and even has a name?

I must have been around 4-5 years old watching it, so the cartoon has to be from 1992 or (much more likely) earlier.

It was about some green goblin/gremlin/troll, I remember the character had a tail with a tuff at the end and long ears (so less humanoid than say, David the gnome, but more human faced than Toadie from Gummi Bears.). I think the character also wore some big hat.
The style was somewhat similar to The Last Unicorn (I think).
The name of the series was some fantasy word, like the character's name, but it was a rather outstanding one. I just can't remember it. I read "Hubbedidick" in another forum and I think that rings a bell!

I don't remember the plot at all, but I do remember that I absolutely loved the series, and there is a very vivid memory about me sitting above the TV magazine telling my back-then babysitter about my favourite shows, and when I pointed at the screenshot of the series, she said it's one of her favourites, too. I think it was one of those series that always came with morale-of-the-day stories.

I really wished I had more information than that, but I really don't.
