I've been racking my brain trying to figure out what movie this is.

It's about a young girl and her brother (I think) and they end up in an another world and there's some type of little troll or goblin helping them and they have to save a princess.

I really don't remember much else than that, I know it's not Never ending story. And I want to say the title had green in it, like the green emerald or something.

Any ideas?

Maybe The Great Land of Small?

Yes! You're amazing! Thank you!
