Feruza(LOL god I dunno if anyone can spell this name right, i'm sure I haven't.) sure is in alot of witch type movies. The Craft and The Worst Witch she played a witch. Then in return to oz mambie was sort of a witch type charactor.
I used to watch a wizard of oz cartoon years and years ago where Dorothy had blonde hair and she actually brought pie with her in her picnic basket to oz somehow LOL. I don't think it's the one your talking about though because in this one it was the normal scarecrow, lion, tin man, etc. I remember the tin man I think stepped on a bug and killed it, he was really upset. I do beleive that the voice of dorothy was Aileen Quin the girl who played "Annie". It was from 1982. I also distinctly remember the wizard showing up as a different type of creature to each charactor..like a rhino to say the tin man and a different animal to the scarecrow, etc.
