Finally got this film's name; need help with another ...

Like many, I had seen this film, repressed (what I remember as) some of the dark and disturbing parts, and thought the whole thing might have just been a dream or nightmare until I came here and realized it wasn't.

But there's another film that I must've seen very close to seeing this film, a film that for the life of my I can't remember. It's a strange movie my sisters watched a lot when I was younger. It has some strange puppets in it, and the goal of the main character is to go into some wicked witch's realm and retrieve some magic tomatoes (or cherries or something similar) that will heal you, somehow; she's trying to bring them back to her world (through a mirror? I can't recall) to save her dying grandfather. And it's all sorts of craziness - I think I remember a moment where they open a door to a new realm and the whole world has shifted 90 degrees and they have to walk in a strange way - but finally the girl/woman/I don't remember succeeds, brings the tomatoes back, but she slips and they roll on the floor and just disappear in some kind of strange magic puff.

It's not Labyrinth, but those are the kinds of films my sisters watched back then. Any help on what this film is would be much appreciated.
