So I'm desperately looking for this cartoon movie where this girl used to live in the mountain, but there is no trees around, just green grass. I think her name was marry or something close to that. I believe the movie starts with an old man which could be her father or grandpa that calls her name, and she's playing around the mountain. I'm not sure I also vaguely remember a evil trying to get her throughout the movie, and also she goes to another world in a flying-ship, where when she gets to this world people are celebrating,like a festival a lot of balloons are up in the sky, and she's trying to rescue something there, and I believe she defeats the evil monster and goes back to her house at the end in the flying ship. Pllleeeease help me if you know the name of this cartoon movie. I believe the girl was blond, but not positive.
Thank you!
