MY FAVORITE CHARACTER

That would be Gossamer.
He's the sweetest 9-year old I've ever seen, even if he looks like a giant tooth with orange hair and sneakers, LOL.
I love his musical episode, "I Love to Singa" (which, incidentally, was the title and song of a terrific early Tex Avery cartoon at WB).
I just wish he appeared in more episodes than he did.
